Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0019] Rare earth butyl isoprene rubber has excellent corrosion resistance and excellent adhesion, the Mooney viscosity is 60-70ML(1+4)100℃, and the weight average relative molecular mass is 160×10 -4 -200×10 -4 , under this relative molecular mass and viscosity, the cross-linked structure of rare earth butadiene-isoprene rubber is relatively perfect and uniform, with many entangled structures, high cohesive energy density of polymer chains, high energy consumption for tensile fracture, and high tensile strength. And high viscosity, excellent wear performance.

[0020] There is a small amount of isoprene chains in the styrene-isoprene-styrene block copolymer, which can improve the low temperature resistance of the adhesive. And has good elasticity and bonding strength.

[0021] Rare...

Abstract

The invention relates to a solvent type adhesive, which is prepared from the following raw materials in parts by weight: 80 to 100 parts of rare-earth Nd-BIR, 3 to 5 parts of monoethyl maleate modified epoxy resin, 15 to 20 parts of zinc borate, 10 to 15 parts of polymerized rosin pentaerythritol, 2 to 4 parts of chitosan, 100 to 125 parts of styrene-isoprene-styrene block copolymers, 1 to 2 partsof accelerants, 1 to 2 parts of anti-aging agents, 20 to 30 parts of 3-methyl-ethyl-1,5-pentanediol and 100 to 120 parts of butyl cellosolve. The preparation process is simple and novel; the reactiontime is short; low-toxicity solvents are used for replacing benzene solvents; safety and environment protection are realized; the dissolution performance on rubber is excellent.

Description

technical field [0001] The invention relates to an adhesive, in particular to a solvent-based adhesive. Background technique [0002] Solvent-based adhesive is a type of adhesive with a large output. It is made of rubber and plastic as the main material, and is dissolved in a solvent by adding compounding agents. High strength, high elasticity, high peel strength, etc., especially suitable for bonding materials with different expansion coefficients. Now it has been widely used in shoemaking, paper, building materials, canvas, synthetic fibers, leather, metal, wood, etc. With the widespread use and promotion of solvent adhesives, people have higher requirements for its performance and quality. Therefore, it is imminent to develop new solvent adhesives. Traditionally produced solvent-based adhesives have low solid content, Cold resistance is poor. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, this case provides a solvent-bas...
