Amphiphilic polymer chain-containing neoprene latex adhesion agent and preparation method thereof

Abstract

The invention discloses an amphiphilic polymer chain-containing neoprene latex adhesion agent. The adhesion agent comprises the following components in parts by weight: an amphiphilic polymer chain-containing neoprene latex, a tackifying emulsion, a filler, a coagulating agent aqueous solution, an anti-aging agent, a stabilizer, a metal oxide and a thickening agent. With a neoprene latex as a matrix and with methyl methacrylate, methacrylic acid and N,N-dimethyl aminoethyl methacrylate as graft monomers, the amphiphilic polymer chain-containing neoprene latex is prepared by an emulsion graft polymerization reaction. The invention also discloses a preparation method of the amphiphilic polymer chain-containing neoprene latex adhesion agent. The problems of poor storage stability and small initial viscous force are solved, the neoprene latex can be simultaneously skillfully endowed with dispersion stability and demulsification cohesion, and at the same time, the dispersion stability and the initial viscous force of the neoprene latex are improved; and the grafted type neoprene latex adhesion agent has wide application range, high adhesion strength, and remarkable economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a neoprene latex adhesive containing amphiphilic polymer chains and a preparation method thereof. Background technique [0002] Rubber-type adhesives play a pivotal role in many fields of the national economy and in all aspects of daily life, among which neoprene adhesives (referred to as neoprene adhesives) are typical representatives. Solvent-based chloroprene adhesives are strictly restricted by environmental protection and safety regulations because they contain a large amount of toxic, harmful, flammable, and explosive organic solvents, and have been banned by developed countries. Water-based neoprene adhesive is compounded by neoprene latex and other additives, and its main component is neoprene latex. Neoprene latex has the characteristics of environmental friendliness, safety, oil resistance and good contact viscosity, but it has poor storage stability and low initial ...
