Abstract

The invention discloses a neoprene adhesive. The neoprene adhesive is prepared from, by weight, 15-24 parts of neoprene rubber, 4-13 parts of tackifying resin, 0.4-1.5 parts of active magnesium oxide, 0.3-1.0 part of antiager, 55-70 parts of organic solvent, 1-8 parts of solids and 0.1-1.3 parts of coupling agent. By the adoption of the technical scheme, the neoprene adhesive has the following advantages that the neoprene rubber, the tackifying resin, the solids, the antiager and other additives are combined, and the neoprene adhesive is good in weatherability, high in solid content, low in VOC content, more environmentally friendly, stable in viscosity, non-layering and excellent in bonding performance. The invention further discloses a preparation method of the neoprene adhesive.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a chloroprene adhesive and a preparation method thereof. Background technique [0002] Neoprene adhesive is a solvent-based rubber adhesive. Conventionally prepared neoprene adhesive method, the main components are high crystalline neoprene rubber, tackifier, solvent, additives, etc., with sufficient supply of raw materials and low cost, simple production, high initial adhesion of the adhesive, and high bonding strength , good weather resistance, wide application range and so on. Widely used in furniture, leather, construction, interior decoration and other industries. [0003] In the observation of new urban construction, formaldehyde has become the main source of indoor pollution in the process of interior decoration. In addition, the toxicity of solvents used in adhesives is also an issue that needs to be considered urgently. The tackifier used in the traditional preparation of chl...
