Abstract

The invention relates to an aqueous neoprene adhesive agent and the preparation method, which belongs to the fields of the elastic bonding adhesive with porous material and the preparation. According to the mass ratio, the aqueous neoprene adhesive agent comprises 100 mass parts of high crystalline aqueous neoprene latex, 10 mass parts to 35 mass parts of polyacrylate, 0.2 mass part to 2 mass parts of aromatic poly alcohol and ether aqueous dispersion, 0.001 to 0.01 mass part of penetrating agent, and 0.001 to 0.01 mass part of defoaming agent. The invention provides the aqueous neoprene adhesive agent without the pollutant of triphen and the like which is urgently need on the market. The aqueous neoprene adhesive agent has the advantages that the viscosity is moderate, the operating time is long, the adhesive agent can be suitable for the flow line production, spraying and brushing, different construction conditions and operating requirements can be satisfied, and the application scope is wide.

Description

[0001] The invention relates to a water-based neoprene adhesive and a preparation method thereof, and belongs to the field of elastic and porous material bonding glue and its preparation. Background technique [0002] Neoprene adhesives are divided into solvent-based and water-based. Solvent-based chloroprene adhesives have excellent performance indicators, but they are basically triphenyl (benzene, toluene, xylene) solvent-based and contain a large amount of harmful organic substances. Since the solvent in neoprene is often released into the air during use, the excessively released harmful gas will seriously pollute the environment, and at the same time, it will slowly release organic gas after decoration, which will also bring harm to people's health. Neoprene latex has achieved great success in water-based neoprene adhesives. It is characterized by low toxicity and environmental protection, non-combustible safety, and resource saving, which represents the development direct...
