Description
Involved in the present invention is is the two-component materials of the chemicosolidifying of major ingredient with urethane, has also set forth the method for manufacture and use thereof of these materials simultaneously.
We know, hardenable urethane illustrated in relevant document, for example, United States Patent (USP) 3,933, illustrated with single step process to make diphenylmethanediisocyanate carry out chemical reaction can the harden process of oligourethanes (Oligourethanes) of manufacturing for No. 725 with polyoxypropylene diols and polyoxypropylene triol.
United States Patent (USP) 3,707 has been set forth the process that excessive vulcabond is produced oligourethanes with the chemical reaction of polyoxy enediol for No. 521, obtains still to contain the goods of former isocyanate groups by these processes.Then, products obtained therefrom reacts with polyoxy alkene triol and generates branched urethane, contains the free isocyanate groups.
The goods that obtained according to the method (or similar method) that these patents disclosed are a kind of because of CO
2Effusion and cause the hardened product of inferior quality.The reaction scheme of the sclerosis of the active oligourethanes R-N=C=O of moisture below can proximate usefulness is illustrated:
The sclerosis of making moist may cause the generation of harmful bubble, and hardenability depends on airborne water content on exhausted big degree, is difficult to control.Process of setting is to expand to internal layer from outermost layer lentamente, and for two constituent materials, does not carry out in entire scope simultaneously.
Set forth the hardening technique of the oligourethanes that contains isocyanate groups in No. 30 19 356, Germany patent application, it has used the latent hardening agent, and for example, aldimine is with oxazolidine.Also recommended in the document to be used as the latent hardening agent with two enamines.Under these conditions, although added these stiffening agents, hardened speed still depends on moisture and the rate of diffusion of being transmitted by surrounding environment thereof.Equally, its sclerosis also be little by little from the outside to internal divergence, for thick-layer, just need the longer time.
The isocyanate functional groups protective material is recommended as follows in the urethane: hydroxymethyl ether, malonic ester, hexanolactam, phenol and ketoxime (about this point, see also Germany patent application 29 46 085; 25 42 500; 25 50 156 and 29 29 224).Yet, use protective material hardened shortcoming be need be higher temperature, often may cause the generation of bubble owing to cause the effusion of volatile products.
United States Patent (USP) 3,054 has been described for No. 755 by polymeric polyisocyanate with polyalkenyl glycol (polyalkenyl ether ethylene glycol) reaction, generates the process of urethane then with the reaction of amino alcohol.United States Patent (USP) 3,228, the prepolymer of having described to contain isocyanate group for No. 914 is with the reaction of amino alcohol.This material is depressed with adding at elevated temperature, finally is to come hardened by additional aromatic diisocyanate monomer.United States Patent (USP) 3,114 has been described the compound that is generated by amineothiot and amino two mercaptan and the terminal urethane resin reaction that has isocyanate group for No. 734.This material is to carry out sulfurized by the oxidation of thiohydroxy.
Above-described each pair component system all has weak point,, must use their component according to the stoichiometry mixing match fully usually that is, otherwise, the product that generates will have very big-difference, and its physical property often can not be satisfactory, and hardening strength is also let matters aside.The situation that does not need the stoichiometry mixing match usually is relevant with a kind of low molecule crosslinked vehicle.In this case, setting rate usually is so fast, and it is extremely difficult consequently controlling it, also will cause product to lack required physical property simultaneously.
It is found that, a kind of prepolymer (1) (has the free isocyanate functional group, from a kind of diisocyanate monomer or polymeric polyisocyanate, obtain) and by have a kind of prepolymer of isocyanate group by end, mix with reacting formed second component (2) one of in thiohydroxy alcohol, amino alcohol and same hydroxycarboxylic acid, thiocarboxylic acid or the aminocarboxylic acid simultaneously, the mixture that obtains has as beyond thought beneficial characteristics such as bonding, coating, packing and moulding materials.
The fixedly blending ratio of the advantageous feature of these materials and its component does not have confidential relation.They are easy to control and processing treatment, and noticeable especially advantage is: these hardened materials get soon and thoroughly, therefore also needn't be overheated in its depths, so do not have the bubble generation.
The purpose of this invention is to provide a kind of two-component materials, in this two-component materials, the oligourethanes and second component that contain free isocyanate groups group of common single-component are mixed together processing, compare with material is arranged earlier, and second can find following some improvements.Two-component materials should be able to be in very wide variable ratio scope intermingling, and do not reduce quality.
Under hardened situation, product is uniform and stable all the time.
Than obtaining faster with the active oligourethanes of moisture and sclerosis more completely.
Can prevent generally speaking by CO
2With the formed bubble of the diffusion of other return volatile reactants.
Can simplify process of setting widely.

An example as the bicomponent material production process, the prepolymer of the second component reaction product can be produced by the raw material of the prepolymer same composition that comprises with first component, and NCO content is 0.5 to 1.5 times (preferably 0.8 to 1.2 times) of the NCO amount of prepolymer in first component in the prepolymer of the second component reaction product.
Usually in order more to simplify, the first component prepolymer also can be used as produces second component, because fairly simple like this, product is more even, and can interreaction in bigger proportional range at bicomponent material under the situation that does not change its characteristic.In order to obtain certain effect, can produce the prepolymer of a component by polymeric polyisocyanate as in a component, obtaining bigger degree of crosslinking, and produce the prepolymer of another component by vulcabond.Select for use different polyvalent alcohols to produce prepolymer and can access distinguishing similar possibility.Second component is the reaction product by prepolymer and active compound, comprises bioactive molecule group in this active compound: hydrogen, hydroxyl, sulfydryl, amino and/or carboxyl.
So active compound can contain 2 to 6 (preferably 2 to 3, particularly 2) hydrogenous bioactive molecule groups.Such material has mercapto alcohol, amino alcohol, hydroxycarboxylic acid, thiocarboxylic acid or aminocarboxylic acid.Like this examples of material comprise mercaptoethanol, mercapto-propanediol, dimercaprol dimercaptopropanol, monoethanolamine, aminopropanol, amino-propanediol, N-methylamino ethanol, N-methylamino propylene glycol, N-methylglucosamine, amino-phenol, hydroxyethyl piperazine, oxyacetic acid, lactic acid, thioglycolic acid, thiolactic acid, aminoacetic acid or Methionin.
In the reaction of the prepolymer of producing second component, should be specifically noted that guarantee formed reaction product be a kind of contain free, can with the hydrogenous molecular grouping of isocyanate reaction.According to the present invention, be used for the reactive activity compound have at least two different can with the reaction molecular group of isocyanic ester radical reaction, obtained this conclusion by such fact.
According to the present invention, production process based on the hardened bicomponent material of urethane is: the prepolymer of first and second components is to be formed by at least a aliphatics or aromatic diisocyanate monomer or polymeric polyisocyanate and at least a polyol reaction that is less than an equivalent value, but this polyvalent alcohol polyethers, polythioether, polyester, polycaprolactone, polycaprolactam, polycarbonate, polyacrylic ester, polymethacrylate, urethane and hydrocarbon polymer.No matter select the sort of compound for use, have 2 hydroxyls in the molecule at least.
In implementing the necessary three kinds of reactions of the present invention, the ratio of its concrete dosage is as follows:
(1) vulcabond and polymeric polyisocyanate and polyvalent alcohol generate in the reaction of prepolymer, and its blending ratio still is left some free isocyanate end after being chosen such that i.e. reaction, and these end groups are used as final reaction or are used for preparing second component.The equivalent ratio of isocyanic ester and hydroxyl is about 1.3: 1 to 3 to 1.Proved already that specially suitable equivalent ratio was 1.5: 1 to 2.2: 1.
(2) generate in the reaction of second component for prepolymer,, will by definition, in the compound of reaction molecule, have 2 reactive functionality at least with 0.8 to 1.2 molar compound of reaction to each normal isocyanate functional group.This point has guaranteed that reaction product (i.e. second component) has and can carry out reactive activity group with the isocyanic ester group of first component that final product can be finished reaction thus.
(3) mixture ratio of final step (i.e. the mixing of two kinds of components) is not very strict.It can change in 0.8: 1 to 5: 1 scope.NCO in the normally used mixture: the equivalent ratio H(active hydrogen) be by 1: 1 to 5: 1(preferably 1.2: 1 to 2: 1) in general, though used feed amount mixture blending ratio change also can with moisture phase reaction in the air that is presented under the final condition.
General reaction conditions:
Produce being reflected in 20 ° to 130 ℃ the temperature range of two components and carry out, be preferably in 40 ° to the 80 ℃ scopes, and under shielding gas (as, nitrogen), stir.If compound of reaction is not sufficient fluid, as mentioned above, the reaction in solvent is possible or even desirable.Yet, be not need solvent under many circumstances.As mentioned above, it also is possible using the catalyzer that quickens isocyanate reaction, and the reaction at the higher macromolecular compound that compares also is desirable simultaneously.Additional and the omission of catalyzer can influence characteristic and the setting time that compound keeps.
The bicomponent material of producing according to the present invention can be used as gluing, coating, sealing-in and the compression moulding material of building structure, also can be used as the construction material of aircraft and steamer simultaneously.When they use as binding agent, but the sheet glass of sealing-in and bonding construction and installation sheet glass or vehicle and aircraft.They can be widely used for coating and the seal, sealing materials that the slab gluing is produced, be particularly suitable for the sealing-in of concrete structure, the coating of roofing, the covering on floor, as, the substrate of carpet, carpet, in general, when using as covering material, can be wear-resistant and skid, bump that can anti-stone in vehicle, aircraft and naval construction material.When using as plastic compression material or plastic compression fat, they can be in the product of plastic compression thing and cast thing, for example, but in electronic applications the various elements of compression moulding.
Usually these bicomponent materials can not use separately.They often use with other auxiliary agent and additive, as, fluidizer, solvent, filler and weighting agent, thickening material, protective agent and other can obtain the additive of better characteristic.For example, can improve the silane of clinging power characteristic.By priming paint and priming paint (for example, silane of having known and/or isocyanic ester), various materials all there is very good clinging power.
For refractory equipment, can mix into inhibition flame additive, as aluminium hydroxide, ANTIMONY TRIOXIDE SB 203 99.8 PCT or contain the additive (as polyvinyl chloride powder) of fontanel element.In order to improve conductivity, graphite or metal powder can be added in the material and be gone.In order to make it more inexpensive and improve wearing character, additional rubber meal or rubber grain also are possible.
Therefore, the present invention has also designed the use of mixture, and mixture is made up of the prepolymer that contains isocyanic ester and second component.Second component is to be generated with isocyanate reaction respectively by prepolymer that contains isocyanate end and active compound (this compound has 2 hydrogenous molecular groupings at least).Mixture can be used as self-hardening gluing, coating and seal, sealing materials.
It is to be noted that especially the present invention has established can be as gluing, coating, sealing-in and the plastic compression mixtures of material of self-hardening.Mixture is to be mixed by the prepolymer and second component.Contain isocyanate end in the prepolymer, and be to form by vulcabond or polymeric polyisocyanate monomer and polyol reaction.Second component composition be by prepolymer (may same or similar) and mercapto alcohol, amino alcohol, and hydroxyl, sulfo-or amino carboxylic acid reaction form.
Bicomponent material major advantage of the present invention is as follows:
(1) in view of with the first excessive component, by the airborne moisture excessive N CO group of can hardening, do not changing greatly under the situation of resulting product performance, the ratio of binary mixture (0.8: 1 to 5: 1) in the scope of broad changes.For the production of bicomponent material, usually not that the hand with the chemical analysis trainer carries out, under simple or even primary working conditions, this point is easy to obtain the product of uniform equal in quality.In contrast, with the production of the two-pack of known modern technique, the ratio that must very accurately manage mixture is so that obtain product with the characteristic that requires.Variation range (10～15%) according to known modern technique method may cause tangible downgrade.
(2) the one the second components by the blending ratio of having recommended (approximately from 1: 1 to 2: 1 or more than) can obtain product, under the interaction that does not have atmospheric moisture, form fully soon netted, and depth direction get with surface reaction (fully) the same fast.For the active oligourethanes that contains the isocyanate functional group of known moisture, this is a very big advantage, make this functional group (crosslinked) formation netted, and under the reaction of atmospheric moisture, harden to inside from the surface, on the other hand, CO
2Become unbound state, this free CO
