Abstract

The invention relates to a solvent type rubber adhesive and a preparation method thereof. The solvent type rubber adhesive comprises the following components in parts by weight: 10 to 20 parts of synthetic rubber, 5 to 30 parts of tackifying resin, 0.5 to 1.3 parts of vulcanizing agent, 0.1 to 0.5 part of catalyst, 40 to 60 parts of mixed solvent, 0.2 to 10 parts of sheet composite powder and 0.1 to 5 parts of migration inhibitor. The solvent type rubber adhesive and the preparation method thereof have the following beneficial effects that: 1. the solvent type rubber adhesive is lowly toxic and environmentally friendly; 2. the plasticizer barrier property is good, the dispersion uniformity of additives in a matrix is improved through the synergistic effect of the sheet composite powder and the migration inhibitor, and the plasticizer migration inhibiting ability and durability of an adhesive film are greatly improved through main body material vulcanization.

Description

technical field [0001] The invention relates to a solvent-type rubber adhesive, in particular to a solvent-type rubber adhesive capable of inhibiting plasticizer migration. The present invention also relates to a preparation method of the solvent-based rubber adhesive. Background technique [0002] Solvent-based rubber adhesive, commonly known as "universal glue", is mainly composed of thermoplastic styrene-butadiene rubber or neoprene, tree tackifying resin, organic solvent, additives and other materials. It has simple preparation process, low viscosity, high solid content, and wide application range. wide features. It is mainly used for the bonding of soft and hard materials such as wood, aluminum-plastic panels, leather, artificial leather, plastics, rubber, and metal. The application fields involve home decoration, architectural decoration, furniture manufacturing, automobile manufacturing, leather luggage products, etc., and are well received by the market. favor. ...
