Abstract
Leather adhesive, it belongs to esters of acrylic acid or α-Qing Jibingxisuanzhi class tackiness agent.This tackiness agent is a caking agent with acrylic ester emulsion or the modification acrylate and the α-Qing Jibingxisuanzhi that are added with the polyvinyl acetal thing, adopts by 2,4 diacetylmethanes, isopropenyl acetate, benzene, methylene dichloride, acetone, ethanol, Resorcinol, 200
#The mixed solvent that solvent oil is formed is formulated.Because of caking agent contains vinyl and various active group, mixed solvent has extremely strong dissolving or swelling effect to polymer substance, thus can bonding effectively leather, and quick solidifying, advantage that cost is low are arranged.
Description
The present invention relates to tackiness agent, relate in particular to esters of acrylic acid and cyano-acrylate binder.
Leather and goods thereof, as: leather shoes, leather boots, fur clothing, leather system case and bag etc., all be people's indispensable article of living, the annual value of production of China's leatherware is more than 5,000,000,000 yuan, so the technological innovation in its production process all will produce considerable social benefit and economic benefit.From adhesive technology progressively substitute sew up technology since, not only the leather utilization ratio is improved, and has improved production efficiency more greatly.Because people are to the demand sharp increase of leather goods and the raising of chemical industry technology, the under-supply vacancy of natural leather has been gone on the market, filled up to imitation leathers such as big weight polyurethane, polymeric amide, amino acid, polyvinyl chloride, ethylene-vinyl acetate successively, so current leather goods material is quite numerous and jumbled.
As everyone knows, make the leatherware troublesome poeration, production efficiency is low, but its goods can keep original snappiness of leather and air permeability and good fully.With the melt viscosity connection substitute make after, production efficiency is greatly improved undoubtedly, but the snappiness of the leatherware after the undeniable thermal treatment and ventilation property have descended.The employing of neoprene latex and polyurethane adhesive, leather and goods thereof bonding removed the processing of heating from, make the quality of leather goods obtain guarantee, but its shortcoming is: tackiness agent set time oversize (more than 20 hours), its price is also more expensive, and the cracking that occurs when goods are bonding is difficult for mending sticking.
The present invention's purpose is: provide a kind of bonding strength higher, can be water-fast, temp. variation resistant, snappiness be good, ageing-resistant, solidify cold bonding type tackiness agent faster.
The present invention realizes above-mentioned purpose like this:
Because the main composition of natural leather is amino acid protein class and animal fibre, and imitation leather is by homopolymer or multipolymer with the vinyl material of some active gene mostly, thus the corresponding selection of tackiness agent of the present invention with the vinyl material of band active group as gluing main composition: the mixed type solvent of selecting in addition natural leather and leatheroid family macromolecule are had strong dissolving or a swelling performance is as one of component of leather adhesive.
This leather adhesive is made up of bonding composition and solvent two parts.Bonding composition wherein is made up of acrylic ester emulsion or modified acrylate emulsion, α-Qing Jibingxisuanzhi, and the ratio of above-mentioned two components was advisable with 3: 1, and the content of the total amount of two components in tackiness agent is advisable with 80%.Described acrylic ester emulsion is any one emulsion in the acrylate such as third-benzene emulsion, the third-the third-benzene emulsion, ABS, EVA, MBS or the mixture of several emulsions.Modified acrylate emulsion is with the contract product of any one or several polyvinyl acetal thing and acrylic ester emulsion mixing gained in urea aldehyde, the polyvinyl alcohol furfural of polyvinyl formal, polyvinylacetal, polyvinyl butyral acetal, polyvinyl alcohol.α-Qing Jibingxisuanzhi is the ester in methyl, ethyl, alpha-cyanoacrylate butyl ester, the isobutyl alpha-cyanoacrylate or the mixing alpha-cyano propylene olefin(e) acid ester of several esters.Mixed solvent in this tackiness agent is by the diketone of 4～6 carbon atoms, isopropenyl acetate, benzene or derivatives thereof, methylene dichloride or tetrachloroethane, acetone, ethanol, Resorcinol, 200
#Solvent oil is formed, and the part by weight of above-mentioned each component in mixed solvent was with 1: 3: 4: 1: 2: 4: be advisable at 1: 4, the content of mixed solvent in tackiness agent is advisable with 20%.The diketone of described 4～6 carbon atoms is saturated diketone or unsaturated diketone or ring diketone, is the best with 2,4 diacetylmethanes wherein; Described benzene derivative is any material in toluene, dimethylbenzene, vinylbenzene, xylidine, the Diethyl Aniline or the mixture of several materials.
The optimum formula of this leather adhesive is:
Third-benzene emulsion or modified acrylate emulsion 60%
α-Qing Jibingxisuanzhi 20%
Mixed solvent 20%
Wherein: 2,4 diacetylmethanes 5%
Isopropenyl acetate 15%
Benzene or toluene or dimethylbenzene 20%
Methylene dichloride or tetrachloroethane 5%
Acetone 10%
Ethanol 20%
Resorcinol 5%
200
#Solvent oil 20%
Embodiment and effect:
This leather adhesive is through using, it is easy to use to prove that it has, can be under 70 ℃ of conditions dry solidification, be not more than 6 hours set time, the bonding strength height, ageing resistance is good, and the adhesive linkage snappiness is good and water-fast, all can implement effectively bondingly to natural leather and leatheroid, and price is far below neoprene latex.After testing, the performance of this tackiness agent is as follows: degree of peeling off: 18kg/2.5 centimetre, and dipping time: 6～8 seconds, drying temperature: 70 ℃, the bonding time at initial stage: 15～20 minutes, normality, bonding time: 48 hours, tentatively realized the present invention's purpose.
