[0018] The present invention also provides a method for preparing a neoprene adhesive, wherein the method comprises: mixing the above neoprene adhesive composition with a solvent;

[0019] Wherein, relative to 100 parts by weight of chloroprene rubber, the amount of solvent used is 450-700 parts by weight; preferably, relative to 100 parts by weight of neoprene rubber, the amount of solvent used is 550-650 parts by weight.

[0020] The solvent may be a type of organic solvent conventionally used in the preparation of adhesives. In the present invention, in order to achieve a better adhesive effect, the solvent is toluene.

Embodiment 1

[0024] Put 100g of neoprene, 40g of styrene-butadiene-styrene block copolymer, 70g of porcelain powder, 4g of magnesium oxide, 3g of zinc oxide and 550g of solvent in a sol kettle and mix and stir for 30 hours to obtain adhesive A1 .

Embodiment 2

[0026] Put 100g of neoprene, 45g of styrene-butadiene-styrene block copolymer, 75g of porcelain powder, 5g of magnesium oxide, 4g of zinc oxide and 600g of solvent in a sol kettle and mix and stir for 30 hours to obtain adhesive A2 .

Abstract

The invention discloses a neoprene adhesive composition. The composition comprises neoprene, styrene-butadiene-styrene block copolymer, porcelain powder, magnesium oxide and zinc oxide, wherein relative to 100 parts by weight of neoprene, the content of the styrene-butadiene-styrene block copolymer is 30-60 parts by weight, the content of the porcelain powder is 60-90 parts by weight, the content of magnesium oxide is 2-8 parts by weight, and the content of zinc oxide is 2-8 parts by weight. Through adding the styrene-butadiene-styrene block copolymer and the porcelain powder filler into the traditional neoprene adhesive, a prepared adhesive can have the heat resistance of the porcelain powder and accordingly can be applicable to the kind of environments, and the use range of the adhesive is enlarged; meanwhile, through adding the filler into neoprene, the adhesive property of adhesives which simply contain neoprene is further improved, so that the effects of good adhesive property, good heat resistance, convenience and practicability are achieved.

Description

technical field [0001] The invention relates to a rubber adhesive, in particular to a neoprene adhesive composition and a preparation method of the neoprene adhesive. Background technique [0002] Rubber adhesive is widely used in the preparation process of rubber product, and neoprene adhesive is as a kind of rubber adhesive, uses also comparatively general in rubber adhesive, but the neoprene used in the prior art The rubber adhesive is usually a single combination of neoprene and solvent, which makes the heat resistance and adhesion of the adhesive insufficient. Therefore, in the process of bonding rubber products, especially in the process of bonding different rubber products, Often can cause bonding is not firm, because environment overheating causes phenomenons such as the product quality after bonding is poor, and then makes the product quality that makes also be affected greatly. [0003] Therefore, it is an urgent problem to be solved in the present invention to pr...
