Abstract

The invention relates to an environment-friendly water-based adhesive and a preparation method thereof and belongs to the technical field of preparation of environment-friendly water-based adhesive. The environment-friendly water-based adhesive is prepared from the following ingredients in percentage by weight: 20-70 parts of neoprene latex, 20-40 percent of deionized water, 1-4 percent of emulgator, 0.5-3 percent of crylic acid or methacrylic acid, 4-30 percent of butyl acrylate, 1-10 percent of methyl methacrylate, 1-3 percent of a stabilizer and 0.3-0.8 percent of an initiator. The environment-friendly water-based adhesive has low requirement on production equipment, non-toxic, environmentally friendly, and difficult to combust, is in a self drying type, and is rapid in bonding, high in bonding strength and suitable for industrial production. The environment-friendly water-based adhesive is convenient to operate and high in safety, and can be subjected to roller coating by virtue of a roller; the production efficiency is high.

Description

technical field [0001] The invention relates to an environment-friendly water-based glue and a preparation method thereof, belonging to the technical field of preparation of the environment-friendly water-based glue. Background technique [0002] Spray glue is used for the bonding of sofa sponge, foam, cloth, leather, paper, wood, plastic, PVC, PE, EVA, metal, rubber, heat insulation cotton, fireproof board, aluminum-plastic board and other materials. However, with the enhancement of environmental protection awareness, the spray glue sold in the existing market has been increasingly unable to meet the needs of the market. Trace it to its cause, mainly be that existing spray glue has the problems of poisonousness, easy burning (low boiling point), and inconvenient transportation. Contents of the invention [0003] In order to solve the above problems, the present invention provides a non-toxic, non-flammable, environmentally friendly water-based adhesive and a preparation ...
