Abstract

The invention provides a formula for nanometer zinc oxide modified neoprene rubber spray coating adhesive. The formula consists of TA-85 neoprene rubber, nanometer zinc oxide, magnesia, magnesia 150, age inhibitor BHT, calcium silicate, liquid resin, FRJ-551 alkyl phenolic resin, methylbenzene, cyclohexane, n-hexane, acetone and water. The invention also provides a preparation method for the nanometer zinc oxide modified neoprene rubber spray coating adhesive. The heat resistance of the nanometer zinc oxide modified neoprene rubber spray coating adhesive provided by the invention can be improved by 20 to 86 percent than the ordinary neoprene rubber spray coating adhesive.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a spray-type adhesive of nano-zinc oxide modified chloroprene rubber and a preparation method. Background technique [0002] Because neoprene spray adhesive has the characteristics of easy operation, fast drying, high initial tack strength and final strength, it is widely used in industrial manufacturing fields such as architectural decoration, office furniture, kitchen furniture, computer room electrostatic floors, air conditioners, car and locomotive interiors, etc. is widely used. However, the existing neoprene spray-type adhesives have a maximum heat resistance of <110 °C, which is not suitable for the fire-proof board flanging bonding line process and the application environment of the interior parts of the car and other occasions where the ambient temperature is high. Therefore, it is necessary to improve the neoprene spraying. heat resistance of adhesives...
