Definitions
- the present invention relates to methods for the production of shoes, in which the shoe upper is adhesively connected to a sole based on foamed thermoplastic polyurethane.
- the invention relates to shoes obtainable in this way, in particular shoes containing a foamed midsole, adhesively bonded to the shoe upper without an adhesion promoter, and a compact outsole, the foamed midsole being expanded thermoplastic polyurethane.
- Thermoplastic polyurethanes are semi-crystalline materials and belong to the class of thermoplastic elastomers. They are characterized, among other things, by good strengths, abrasion, tear propagation resistance and chemical resistance, and can be produced in almost any hardness by a suitable raw material composition.
- the TPE melt e.g. PVC, TR, TPU, etc.
- a so-called rotary table system e.g. 24 stations D612 from DESMA or MainGroup
- Plasticizing unit e.g. SPE 22.65 TPU from DESMA
- DEScom ® process DESMA
- displacer e.g. DEScom ® process
- the upper is positioned over the compact sole, the tool is sealed using side-closing jaws and, in a next step, PUR is introduced into the cavity between the sole and the shaft using a PU metering unit known to the person skilled in the art.
- PUR is introduced into the cavity between the sole and the shaft using a PU metering unit known to the person skilled in the art.
- the shoe is removed from the mold and protrusions on the shoe are deburred.
- tank farms and tank farm connections with heated metering lines are required for processing such a PUR system.
- PUR system waste cannot be recycled using this process.
- Another disadvantage is that contamination of the system and employees can hardly be avoided when handling such a PUR system.
- the mixing element (mixing screw) of the PUR dosing and mixing unit must be replaced at regular intervals after a few shots and cleaned with great effort.
- the object of the present invention was therefore to develop an improved process for the production of shoes in which the shoe upper is adhesively connected to a sole based on foamed thermoplastic polyurethane, which has clear advantages.
- So z. B. the handling of liquid components can be avoided, e.g. to be able to do without tank farms, tank farm connections, heated pipes, PUR mixing and dosing units.
- the recycling of waste should be improved and occupational hygiene at the workplace reduced by reduced pollution.
- the deburring of protrusions should be eliminated, the problems with the lying zone reduced and the surface quality improved.
- the expandable thermoplastic polyurethanes are preferably a mixture of thermoplastic polyurethanes with expandable microspheres, particularly preferably expandable microspheres with a TMA density between 2 and 30 kg / m 3 , preferably between 2 and 10 kg / m 3 , Through this Low TMA densities and comparable density can minimize the weight-based use of microspheres. This leads to cost savings, since the microspheres are usually the price-determining factor with regard to the raw materials of the end product.
- the preferred expandable microspheres can be used in the form of powder or preferably as masterbatches, the microspheres being generally known and commercially available, for example under the Expancell® brand from AKZO Nobel Industries, Sweden.
- masterbatch is to be understood that the expandable microspheres in a carrier z. B. binders, waxes or a thermoplastic (z. B. TPU, EVA, PVC, PE, PP, PES, PS, TR etc. or blends thereof) are bound in granular form.
- a carrier z. B. binders, waxes or a thermoplastic (z. B. TPU, EVA, PVC, PE, PP, PES, PS, TR etc. or blends thereof) are bound in granular form.
- Masterbatches are generally used in thermoplastics with a very low melting point (e.g. 60 - 110 C C) and very low viscosities, in order to avoid premature expansion due to the lowest possible temperatures.
- the use of such masterbatches prevents the formation of dust, such as occurs when using and handling expandable microspheres in powder form.
- the homogeneous mixing of the expandable microspheres with the TPU is easier when using masterbatches.
- the TMA density is defined as the minimum achievable density [kg / m 3 ] of an expandable microspheres powder or a corresponding masterbatch therefrom until the microspheres collapse (conditions: Stare Thermal Analysis System from Mettler Toledo; heating rate 20 ° C / min ; Weight approx. 0.5 mg).
- co-blowing agents such as. B. exothermic (z. B. Azodicarbonamide) and endothermic (z. Citric acid; hydrogen carbonates) chemical blowing agents can be used.
- the expandable thermoplastic polyurethane can preferably contain between 1 and 50% by weight, based on the total weight of the mixture, of plasticizers.
- the TPU can be used as the sole thermoplastic. Alternatively, however, it is possible to use TPU blends made from other generally known thermoplastics. TPU / rubber blends are also possible.
- the TPUs which are generally in the form of powder, granules or pellets, are usually mixed with the expandable microspheres and / or the masterbatch and thermoplastic processed into the shoes and / or shoe parts according to the invention.
- the term “thermoplastic processing” means any processing which is associated with melting the TPU. This can preferably be done by injection molding thermoplastic processing, there is an expansion of the expandable microspheres and thus the formation of the expanded TPU.
- the melt is preferably introduced into molds and cures there.
- the temperature for foaming the TPU is preferably between 130 ° C. and 220 ° C., particularly preferably between 150 ° C. and 190 ° C.
- the expandable thermoplastic polyurethane is preferably injected into a closed mold.
- a tool which is preferably part of a rotary table system which is generally known and commercially available for the production of shoe soles, a preferably compact outsole, preferably based on TPU, crosslinked polyurethane, PVC, TR and / or rubber , particularly preferably produce or insert TPU, cross-linked polyurethane, PVC and / or rubber and then inject and foam the expandable thermoplastic polyurethane into the space of the tool, which is preferably delimited at the bottom by the outsole and preferably at the top by the shoe upper.
- the outsole is preferably based on a compact material.
- the midsole based on the expanded thermoplastic polyurethane preferably has a density between 0.2 and 1.0 g / cm 3 , particularly preferably between 0.4 and 0.7 g / cm 3 .
- adhesion promoters e.g. Avoid the usual adhesives on the interface between the shoe upper and the foamed TPU sole and, if necessary, on the interface between the outsole and the foamed TPU sole.
- the foamed TPU sole sticks sufficiently to the shoe upper or the compact outsole.
- the foamed thermoplastic polyurethane can preferably be laminated with materials such as foils, textiles or leather, particularly preferably by placing the corresponding materials in the tool and then foaming the expandable TPU in contact with the materials. It is surprising that the adhesion of the foamed TPU to the materials is very good.
- the foamed thermoplastic polyurethane is thus particularly preferably adhesively bonded to foils, textiles or leather by the foaming process.
- the customary and known compounds can be used as TPU, as described, for example, in the plastics handbook, volume 7 "Polyurethane", Carl Hanser Verlag, Kunststoff, Vienna, 3rd edition 1993, pages 455 to 466. They are prepared by reacting diisocyanates with compounds with at least two hydrogen atoms reactive with isocyanate groups, preferably difunctional alcohols.
- Aromatic, aliphatic and / or cycloaliphatic diisocyanates customary as diisocyanates for example diphenylmethane diisocyanate (MDI), tolylene diisocyanate (TDI), tri, tetra, penta-, hexa-, hepta- and / or octamethylene diisocyanate, 2- Methyl pentamethylene diisocyanate-1, 5, 2-ethyl-butylene-diisocyanate-1, 4, 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethyl-cyclohexane (isophorone diisocyanate, IPDI), 1.4 - and / or 1,3-bis (isocyanatomethyl) cyclohexane (HXDI), 1,4-cyclohexane diisocyanate, 1-methyl-2,4- and / or -2,6-cyclohexane diisocyanate, 4,
- Well-known polyhydroxyl compounds with molecular weights of 500 to 8000, preferably 600 to 6000, in particular 800 to 4000, and preferably an average functionality of 1.8 to 2.6, preferably 1.9 to 2.2 can be used as compounds which are reactive toward isocyanates , in particular 2 are used, for example polyesterols, polyetherols and / or polycarbonate diols.
- Preferably used as (b) are polyester diols which can be obtained by reacting butanediol and hexanediol as the diol with adipic acid as the dicarboxylic acid, the weight ratio of butanediol to hexanediol preferably being 2 to 1.
- polytetrahydrofuran with a molecular weight of 750 to 2500 g / mol, preferably 750 to 1200 g / mol.
- chain extenders for example diamines and / or alkanediols having 2 to 10 carbon atoms in the alkylene radical, in particular ethylene glycol and / or 1,4-butanediol, and / or hexanediol and / or di- and / or Tri-oxyalkylene glycols with 3 to 8 carbon atoms in the oxyalkylene radical, preferably corresponding oligo-polyoxypropylene glycols, it also being possible to use mixtures of the chain extenders.
- diamines and / or alkanediols having 2 to 10 carbon atoms in the alkylene radical in particular ethylene glycol and / or 1,4-butanediol, and / or hexanediol and / or di- and / or Tri-oxyalkylene glycols with 3 to 8 carbon atoms in the oxyalkylene radical, preferably corresponding oligo-polyoxypropylene glycol
- chain extenders are ethylene glycol and hexanediol, particularly preferably ethylene glycol.
- Catalysts are usually used which accelerate the reaction between the NCO groups of the diisocyanates and the hydroxyl groups of the structural components, for example tertiary amines, such as triethylamine, dimethylcyclohexylamine, N-methylmorpholine, N, N'-dimethylpiperazine, 2- (dimethylaminoethoxy) - ethanol, diazabicyclo (2,2,2) octane and similar and in particular organic metal compounds such as titanium esters, iron compounds such as iron (MI) acetylacetonate, tin compounds such as tin diacetate, tin dilaurate or the tin dialkyl salts of aliphatic carboxylic acids such as dibutyltin diacetate, dibutyltin dilautyltinil or similar.
- tertiary amines such as triethylamine, dimethylcyclohexylamine, N-methylmorpholine, N,
- the catalysts are usually used in amounts of 0.0001 to 0.1 part by weight per 100 parts by weight of polyhydroxyl compound.
- customary auxiliaries can also be added to the structural components. Examples include surface-active substances, flame retardants, nucleating agents, lubricants and mold release agents, flow improvers, abrasion improvers, dyes and pigments, inhibitors, stabilizers against hydrolysis, light, heat, oxidation or discoloration, protective agents against microbial degradation, inorganic and / or organic fillers, reinforcing agents and plasticizers, but also chain regulators, such as.
