Problems solved by technology

[0002] In the market, neoprene adhesives are often used for the bonding between many synthetic materials such as artificial leather, synthetic leather, and imitation leather, and genuine leather. Excellent solvent, the performance of the adhesive is also easier to control, the existing neoprene generally contains a large amount of highly toxic "triphenyl" solvent, its use seriously endangers the personal safety of construction workers, such as easy to cause occupational diseases of workers in the shoe industry, and Easy to cause serious pollution to the environment

Embodiment Construction

[0016] The production method of the triphenyl-free high bonding strength environment-friendly neoprene of the present invention: first produce a kind of graft glue, its formula is as follows, methylcyclohexane 35%, ethyl acetate 15%, methyl ethyl ketone 5%, carbonic acid Dimethyl ester 18%, graftable neoprene rubber A-90 13%, SBS HY792 2.5%, monomer MMA 11%, initiator BPO 0.12%, antioxidant BHT 0.38%; then use the graft glue as 100% Parts, add 3 parts of tackifying resin C9 petroleum resin, 2 parts of vinyl resin, 2 parts of p-tert-butylphenolic resin, 1 part of reinforcing agent white carbon black, 0.5 parts of plasticizer dibutyl phthalate, diluent 5 parts of acetone.

[0017] The triphenyl-free mixed solvent system used in the present invention is beneficial to improving the crystallization speed and crystallization regularity of the neoprene, thereby improving the bonding strength; the used auxiliary agent is also beneficial to increasing the viscosity and bonding strength...

Abstract

The invention discloses aromatic hydrocarbon-free neoprene adhesive with high adhesive strength, which is characterized in that graft adhesive is firstly prepared according to the following formula: 10 percent-40 percent of methyl cyclohexane, 5 percent -30 percent of ethyl acetate, 0 percent-10 percent of butanone, 5 percent -30 percent of dimethyl carbonate, 8 percent-15 percent of chlorobutadiene rubber, 0 percent-2.5percent of SBS (thermoplastic styrene-butadiene rubber), 7 percent-15 percent of MMA (methyl methacrylate), 0.1percent-0.2 percent of initiator and 0.1 percent-0.5percent of antioxidant; then the invention is prepared by 100 portions of the graft adhesive prepared according to the formula, 0-10 portions of tackifying resin, 0-3 portions of strengthening agent , 0-3 portions of plasticizers and 0-20 portions of diluents. The product of the invention has the advantages of environmental protection, and high adhesive strength, etc.

Description

technical field [0001] The invention relates to the preparation of neoprene. Background technique [0002] In the market, neoprene adhesives are often used for the bonding between many synthetic materials such as artificial leather, synthetic leather, and imitation leather, and genuine leather. Excellent solvent, the performance of the adhesive is also easier to control, the existing neoprene generally contains a large amount of highly toxic "triphenyl" solvent, its use seriously endangers the personal safety of construction workers, such as easy to cause occupational diseases of workers in the shoe industry, and It is easy to cause serious pollution to the environment. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provide a kind of environmental protection neoprene rubber without triphenyl and high bonding strength. [0004] The technical solution that the present invention adopts in order to achieve above-me...
