preparation example Construction

[0017] The present invention also provides a method for preparing a neoprene adhesive, wherein the method comprises: mixing the neoprene adhesive composition described in any one of claims 1-5 with a solvent;

[0018] Wherein, relative to 100 parts by weight of chloroprene rubber, the amount of solvent used is 550-850 parts by weight; preferably, relative to 100 parts by weight of neoprene rubber, the amount of solvent used is 650-750 parts by weight.

[0019] The solvent may be an adhesive solvent known in the art, and in the present invention, the solvent is preferably ethyl acetate.

Embodiment 1

[0023] 100g chloroprene rubber, 10g styrene-butadiene-styrene block copolymer, 45g resorcinol formaldehyde, 4g magnesium oxide, 3g zinc oxide and 650g solvent were placed in a sol kettle and mixed and stirred for 30 hours to obtain a viscose Mixture A1.

Embodiment 2

[0025] 100g chloroprene rubber, 15g styrene-butadiene-styrene block copolymer, 50g resorcinol formaldehyde, 5g magnesium oxide, 4g zinc oxide and 700g solvent were placed in a sol kettle and mixed and stirred for 30 hours to obtain a viscose Mixture A2.

Abstract

The invention discloses a neoprene adhesive composition. The composition comprises neoprene, styrene-butadiene-styrene block copolymer, resorcinol formaldehyde resin, magnesium oxide and zinc oxide, wherein relative to 100 parts by weight of neoprene, the content of the styrene-butadiene-styrene block copolymer is 5-35 parts by weight, the content of resorcinol formaldehyde resin is 30-70 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 resorcinol formaldehyde resin into the traditional neoprene adhesive, the adhesive property of the prepared adhesive is better, so that the problem of the ordinary neoprene adhesives that the product quality of rubber products is poor due to the fact that the rubber adhesion is not strong is solved.

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, so in the process of bonding rubber products, especially in the process of bonding different rubber products, it often leads to weak bonding and easy loosening, which makes the adhesive The knot effect is poor, and the product quality is also greatly affected. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a neoprene adhesive with good bonding performance and strong practicability and a preparation method thereof.
