Abstract
A water-soluble slurry for treating nylon hasp is prepared from butyl acrylate (12-15.5%), methyl acrylate (2-4%), class-A methyl acrylate (1-4%), styrene (8-21%), emulsifier (0.14-0.16%), trigger (0.24-0.26%)a nd water (56-75%) through polymerization reaction, and features low toxicity and convenient application. The nylon hasp treated with it has high water resistance and rigidity.
Description
The present invention relates in the velcro production process, velcro is carried out the production method of the production method, particularly a kind of water-soluble slurry of nylon hasp of a kind of slurry of post-processed.
At present, in the production process of velcro, to slurry that its post-processed adopted mainly based on polyurethane slurry, produce the raw material that polyurethane slurry adopted and be generally tolylene diisocyanate, arene and amides, the polyurethane slurry cost height that adopts these raw material production to go out, toxicity is big, and flame retardant properties is poor, inflammable and explosive, bad with the stiffening effect of its velcro of handling.
The purpose of this invention is to provide a kind of production method of in the production process of velcro, it being carried out the new slurry of post-processed---the production method of water-soluble paste, adopt this method to produce slurry, low production cost, the slurry nontoxicity of producing, have excellent flame-retardant performance, stiffening effective with its velcro of handling.
For achieving the above object, the technical solution used in the present invention is: raw material of the present invention comprises following various material: butyl acrylate, methyl acrylate, the first class methyl acrylate, vinylbenzene, emulsifying agent, initiator, water, the add-on of various materials is (purity with above-mentioned various materials is being as the criterion more than 99%): butyl acrylate 12-15.5%, methyl acrylate 2-4%, first class methyl acrylate 1-4%, vinylbenzene 8-21%, emulsifying agent 0.14-0.16%, initiator 0.24-0.26%, water 56-75%, various raw materials are added in the reactor, polyreaction is carried out in insulation according to a conventional method, makes the finished product slurry.
For improving the viscosity of the slurry of producing by the inventive method, in raw material, also can add vinylformic acid, its add-on is 0.7-1.5%.
Emulsifying agent is preferably selected at least a of following material for use: Sodium dodecylbenzene sulfonate, dodecyl phenenyl sulfate.
Initiator is preferably selected at least a of following material for use: Potassium Persulphate, ammonium persulphate.
Various materials add in the reactor, carry out series reaction, and its reaction equation is:
Slurry according to method production of the present invention, because of not containing toxic substances such as aromatic solvents, formaldehyde and heavy metal, thereby toxicity is little, safety, convenience during use are through evidence, good with its velcro water tolerance handled and stiffening performance, large percentage because of water in the slurry, thereby have excellent flame-retardant performance, and with low cost, only be 30% of polyurethane slurry commonly used.
For further specifying the present invention, be described below in conjunction with specific embodiment.
