The present invention makes it possible to make shoes in very short period without environmental pollution and to realize mass production of shoes through continuous mechanized and automatic process. The present invention adds an adhesive layer comprising high-frequency magnetic field excited heating material and adhesive between the intermediate sole and outer sole and finish making shoes in short period by selective heating. The said method may be also used for replacing and repairing sole.
Description
The present invention relates to a kind of sole, particularly a kind of sole, particularly, and this sole, it is able to finish in the short time at the utmost point manufacturing of shoes, and is unlikely the pollution operating environment because of using the bonding agent of non-solvent system.
Be not only sport footwear at present, playshoes that other men and women use and footware, industrial operation footwear are arranged again, its most shoes constituent material such as footwear lid, the middle end and outer bottom, all engage with bonding agent, and the operating environment of its manufacturing site location is polluted because of the solvent of bonding agent, becomes maximum problem.Need heat when being engaged, need thermal source in the solvent gas environment, cause to be forced to be in and be operation in the worst adjacent environment with fire.Certainly take all countermeasures for the deterioration that prevents such operating environment, but unavoidably must expend sizable expense.
The deterioration of the operating environment that solvent causes adds that heating and dry a succession of engineering expend time in, and energy efficiency is also poor, how to shorten engineering time and also becomes important problem.
Again at traditional footwear, when its outer bottom wears away, even footwear top portion not damaged is only repaired sole and also is not easy.The result have to be discarded usually.This reclaims today with the environment of preserving our planet shouting resource, and the constituent material that how will discard shoes gives utilization again, also is a problem.
At traditional shoes, outer bottom also adopts foaming method in order to make the shoes lightweight again, the consumption of fast further sole.
Purpose of the present invention is that a kind of sole will be provided, and can form sole through shirtsleeve operation.
Another object of the present invention is that a kind of sole will be provided, and it can be easy to peel off sole, is made the regeneration of footwear become possibility and change sole.
Another purpose of the present invention is that a kind of sole will be provided, and can not use solvent and make shoes under good operating environment.
The object of the present invention is achieved like this:
A kind of sole mainly is made of the middle end and outer bottom, it is characterized in that: be situated between between the middle end and outer bottom at the bond layer of one deck exothermic material and bonding agent combination, this exothermic material is meant the exothermic material that is placed in the high frequency magnetic field.
This exothermic material is by selected at least a in a group magnetic material, metal and the carbon element.
This exothermic material is by selected at least a shape in a group powder, fragmentation shape, laminar, fibrous, the shape of weaving cotton cloth, the netted and multihole lamina shape.
This exothermic material can be covered with priming paint in advance.
This priming paint is thermoplasticity synthetic resin or elastomer.
This priming paint is thermohardening synthetic resin or elastomer.
This bonding agent is thermoplasticity synthetic resin or elastomer.
This bonding agent is thermohardening synthetic resin or elastomer.
Sole of the present invention, it is characterized in that being situated between between the middle end and outer bottom is having novel bond layer.The end and/or outer bottom can engage in when the heating of the exothermic material that this bond layer mat and bonding agent are combined is shaped shoes, when the footwear that have been shaped strip outer bottom, make again shoes body with the end and/or peeling off of outer bottom become possibility.Engage that the bond layer that has only when peeling off between the middle end and outer bottom optionally is heated and the material degradation that do not cause other parts of formation shoes.Can be when peeling off with having produced peeling off of material damage became splitting and other part materials of unlikely damage originally.This moment is can not only amount efficiency high, with implement traditionally around heating means different, the part material that needn't heat does not originally experience heating, so this material does not have the worry of hot deterioration, does not undermine the durability of this material yet.
Sole of the present invention promptly in order to make exothermic material heating, evokes the time of exothermic material its heat time heating time in high frequency magnetic field, for from several seconds to utmost point short time of tens of seconds only.So when adopting sole of the present invention, make the process time of shoes,, significantly shorten than traditional method.
Made shoes with the good local heat of energy efficiency with extremely short process time like this, meaned the epoch-making property rationalization of the manufacture process that can realize shoes.For the footwear manufacturing industry that traditional-handwork carries out has been opened an automation road that converts to by machinery.
The shoes that adopt sole of the present invention to be shaped again because of bond layer is placed in high frequency magnetic field, have only bond layer by the heating and melting of selectivity, and outer bottom is more easily peeled off.So the reparation of the sole of Mo Mieing can be changed the means of outer bottom and become possibility.Because of the fierce outer bottom that consumes of lightweight, also change the prolongation of epoch-making property of the life-span of shoes body as a result easily.Because peeling off easily of sole, the shoes body based on the footwear top when the recovery of shoes is easy to separate with sole, contributes very big for the love of resource.
Sole of shoe of the present invention is because of its use has following all effects.
Sole of the present invention has the bond layer of the exothermic material that generates heat because of evoking of high frequency magnetic field and bonding agent combination, and the heat that only relies on this exothermic material to send out is applied flexibly and made the shoes shaping.Only optionally heat in desired portion, and the heating of the structure of three-D choosing part also becomes possibility, because of as with traditional method from external heat in whole shoes, that is the environment heating means are compared, its energy efficiency is extremely excellent, also can save the energy and the good working environment is provided.Used bonding agent need not used solvent for being the bonding agent at center with the thermoelastic gonosome with hot melt, in this regard and Yan Yike provides good operating environment.Because of it does not use solvent, also do not adopt the environment heating means, so the anxiety of no fire.
Making the means of exothermic material heating, is to adopt the method that is called the high-frequency electromagnetic heating, so can reach the purpose that fulfils assignment in the short time at the utmost point.Again because of belonging to local heat, so can send goods to the back operation after heating is at once.So as use sole of the present invention, not only can significantly shorten the forming process time of shoes, promptly with the automation of the process of mechanization, can realize laborsaving and enhance productivity, and knack must not arranged in the operation, also be one of advantage.
Making the bond layer fusion as long as the bond layer of settling sole in high frequency magnetic field, promptly optionally generates heat, is very easy thing so the shoes of finishing from the present invention will be peeled off its outer bottom, also is another effect of sole of the present invention.For example as you know, the renewal of marathon sports record and the improvement of footwear for marathon running have close connection, so not still lightweight, the functional improvement of shoes material is often pursued.Seeking of lightweight of footwear top and aeration, or the improvement of middle bottom impact absorbency, but the selection of mat material obtains suitable improvement, but the lightweight of outer bottom can say and arrived the limit, and extreme says, and each match is over and just needn't more renew footwear.Yet sole of the present invention, as described above situation its wear off easily, change easily, can be anti-team match institute must maximum lightweight, be replaced with new product and can after match is over, peel off old sole.So still can continue to employ the footwear top of having been habitually practised by the user.For famous marathon runner, be manufactured with difference delicate between the pin of the left and right sides and all given the consideration shoes, can the continuing of footwear top used, be exactly pin wear stability continue keep, do not cause sense of fatigue, can avoid foot's scratch, this is greatest Gospel to the player.
Sole of the present invention is not limited only to the marathon footwear, and to his sport footwear or playshoes of base, the outer bottom of its wearing and tearing all can be easy to regeneration.Only wear away the shoes discarded but footwear top not damaged is also had to because of outer bottom, but mat adopt sole of the present invention and still keep relaxed and comfortable snugness of fit, and help the utilization again of resource.
In addition, adopt the shoes of sole of the present invention, the separating easily of its footwear top and outer bottom when waste treatment, not only the recycling of material is easy, also alleviates the environmental pressure in the offal treatment, and environmental protection and resource are cherished two aspects all to be had in order to do benefit.

As shown in Figure 1 and Figure 2, sole 3 of the present invention constitutes with the middle end 4 and outer bottom 6, in high frequency magnetic field, evoked, itself is with vortex flow and magnetic hysteresis loss and the combined bond layer 5 of the exothermic material that the material that generates heat is made and bonding agent 8, its Jie is between the middle end 4 and the outer bottom 6, constructs with this and form sole 3.The heating of this exothermic material 7 is based on the Joule heat of vortex flow and magnetic hysteresis loss, is its feature and can generate heat at short notice, and utilizes this caloric value in joint.Be placed in the sole 3 in the high frequency magnetic field, preferably with the crimping gently of things such as utensil, the heating of mat bond layer 5 inside, bonding agent 8 moment fusion, and engage.
When formation is equiped with the shoes of sole 3 of the present invention, or when the shoes that sole 3 of the present invention is housed are peeled off its outer bottom 6, then make exothermic material 7 heatings that are fitted to aforementioned bond layer 5.
Exothermic material 7 as used herein, are to belong to because of evoking in high frequency magnetic field, and itself is based on vortex flow and magnetic hysteresis loss and the material that generates heat.Such material, the body that is magnetic, metal or the carbon etc. that can exemplify.These materials can use separately or two or more and usefulness.In this said magnetic, be to refer to the compound with magnetisable character in magnetic field of definition usually, ferromagnetism body preferably, but normal magnetic or diamagnetic substance also can.As with the magnetic particular instantiation, various iron series compounds are arranged then; Ferroalloy and iron series compounds such as iron nickel, ferrimanganic, iron cobalt; Manganese sub-group compound; Nickel series compounds; Titanium sub-group compound; The barium based compound; Palladium based compound etc., but be not to be defined in these.Metal then has iron, cobalt, nickel, various stainless steels etc.Carbon is dielectric constant height preferably then, the carbon of high crystalline, and for example conductive carbon on the market and carbon fiber etc. all are suitable for using.
Beyond the above-mentioned substance, cooperate the moulding material of a large amount of carbon elements such as commercially available electric conductivity polysulfide rubber or its Asia property material in the rubber, all can use.
The shape of exothermic material 7 preferably can produce vortex flow with high efficiency, in the different shape with powder, fragmentation shape, laminar, fibrous, the shape of weaving cotton cloth, adhesive-bonded fabric shape, netted or the multihole lamina shape is preferable.
Exothermic material 7 configuration amount selected, should properly cooperate the bonding agent that uses 8 melt temperatures, it is temperature required that it can be obtained.And for example the frequency of high-frequency generator described later also should take in decision with output.
In order to improve the Combination of exothermic material 7 and bonding agent 8, with the processing mode of priming paint lining exothermic material 7, also be preferable form in advance.
Make the method for these exothermic material 7 heatings, then what is called is called the high-frequency electromagnetic heating means, is divided into medium heating and two kinds of eddy-current heating, and arbitrary mode is all applicable.
Usually to use induction heating method to be advisable.The principle of eddy-current heating, the high frequency electric that promptly utilizes high-frequency generator and produced circulates in induction coil, makes because of induction evokes magnetic field, causes exothermic material and is evoked and produce vortex flow and magnetic hysteresis loss, and utilize the method for the heat that is generated by this.On the other hand, the medium heating principle, promptly be that the high frequency electric that the mat high-frequency generator produces is flowed in two electrodes, exothermic material is placed in the magnetic field of responding between electrode, make it evoke the method that produces vortex flow and magnetic hysteresis loss and utilize its heat that produces.
Being induced field, with the high frequency electric frequency that high-frequency generator produces, is to select for use between 0.1～50MHz when eddy-current heating, limit by the electric wave method during medium heating, usually from 20.3 or 40.6MHz select one among both.Situation as described above, the size of output should be weighed the melt temperature and the properly decision of 7 relations of institute's exothermic material that is used of used bonding agent 8.By the conduction time of the high frequency electric of high-frequency generator vibration, promptly eddy-current heating or medium heat time heating time are its feature with extremely short usually, cooperate bonding agent 8 to reach melt temperature institute calorific requirement and decide heat time heating time, at most short time from the several seconds to tens of seconds.
The combined bonding agent 8 of exothermic material 7 is so-called thermal fusion bonding agent 8 therewith, can suitably select according to purpose.Bonding agent 8 is preferably selected for use and sole 3 homogenous materials resins, and is difficult for heating and goes bad.Usually select thermoplastic elastomer (TPE) for use.For example when formation has the shoes of peeling off comfortable sole, use the bonding agent 8 that is become by thermoplasticity synthetic resin or elastomer.Forming when must not peel off the shoes of outer bottom 6 the available bonding agent 8 that is become by thermohardening synthetic resin or elastomer again.
The softening point that the softening point of bond layer 5 cans be compared to to-be-connected body most is low, when selected bonding agent 8, should consider the softening point of material.When to-be-connected body and bonding agent 8 used the resin of homogeneity, should select the little material of molecular weight for use was bonding agent 8, or cooperates with plasticizer to reach purpose.
The selection of another important document and exothermic material 7 is correlated to some extent when selecting bonding agent 8, and promptly preferably the heat distortion temperature of the resin of bonding agent 8 usefulness should be hanged down 20～30 ℃ than Curie (curie) temperature of exothermic material 7.
To-be-connected body, for example the material and the bonding agent 8 meltability parameters at the middle end 4 are worked in coordination, by this can be as the index that obtains stronger engaging force.Sometimes, be difficult to because of material between to-be-connected body is significantly different with a kind of when connecing agent and engaging, the meltability parameter of preferably considering to-be-connected body is implemented surfaction and is handled, i.e. prime treatment, or use the combination etc. of two or more bonding agents.When peeling off, can cause material damage when working good the meltability parameter usually, but sole of the present invention peels off because of having only bond layer 5 to be satisfied between stratification by the heating of selectivity when peeling off, can not follow the loss that causes the footwear construction material because of destruction.
Can work as bonding agent 8 thermoplasticity synthetic resin, can the person of exemplifying thermoplastic poly urethane for example; Ethylene-vinyl acetate copolymer (EVA); Styrene butadiene styrene piece copolymer (SBS) and the different the eleventh of the twelve Earthly Branches diene of styrene styrene piece copolymer (SIS); Polybutene glycol terephthaldehyde (PBT); Terephthaldehyde's polyester elastomer (TPEE); Polyester elastomer (PEE); Polyamide elastomer (PAE) etc.Wherein more excellent because of hear resistance and low temperature fragility, the thermoplastic poly urethane often is used.The EVA that is commonly used in sole also is fit to as bonding agent 8.But become mobile piece copolymer because of injection molding in the above temperature of glass branchpoint,, also be fit to do bonding agent 8 so often be used to outer bottom 6.The PBT of the ends 4 material also is good bonding agent 8 in being used in.
Shown in Fig. 2～4, constitute the exothermic material of sole bond layer 5 of the present invention and the form of bonding agent 8 combinations, for example have 1) form of disperseing the exothermic material 7 of powder body in the bonding agent 8,2) exothermic material 10 is scattered in the surface of 8 layers of support of bonding agent or inner and make up the form of its support and bonding agent 8,3) as net and multihole lamina, itself have the form of laminal exothermic material 9 and bonding agent 8 combinations, but be not to be defined in this.That is the surface portion that should impose joint of configuration the exothermic material end 4 or outer bottom 6 in shoes, and can use as a kind of distortion of sole 3 of the present invention in the form that basal surface coating adhesive 8 forms bond layers 5.Moreover also can be only make it bring into play the function of bond layer 5 with the surface portion of the material of the middle end 4 or outer bottom 6 itself in the form of this distortion.
When constituting sole in the multilayer mode again, come exfoliation temperature between change layer with the combination of changing each interlayer bonding agent and/or exothermic material kind, only to peel off specific one deck, also belonging to may.Bond layer for example of the present invention can be applicable to engaging of footwear tops and the interior end.The end, can not consume in common, so needn't change, but if use bond layer of the present invention, peeling off and changing of the middle end also belongs to possibility.
The form that is situated between between the middle end and outer bottom at bond layer has 1) evenly mix in the bonding agent with exothermic material, make its dispersion and coat the middle end or outer bottom, 2) with weaving cotton cloth or support such as adhesive-bonded fabric, the bond layer that is become with the convered structure mixture by exothermic material in support surface lamination, 3) the homodisperse support of exothermic material surface coating adhesive is being arranged, 4) coating adhesive is in forms such as lamellar exothermic materials, but and non-limiting that's what it all adds up to.In aforementioned 1) form, preferably use the bond layer that in bonding agent, is dispersed with exothermic material, for example use the anti-setting lotion of permanent hair styling (reverse roll) to coat outer bottom, can prevent the exothermic material sedimentation and separate with bonding agent.The best also anti-setting lotion of coating permanent hair styling during the same bonding agent that uses latex system.In aforementioned 2), 3) and 4) form in prepare lamellar bond layer in advance, cut off this thin plate and become desired shape, patch is practical form in the middle end or outer bottom and form shoes.
