Abstract

The invention discloses a waterborne tackifying resin exclusively used for a PVC electrical adhesive tape, and relates to the technical field of chemical engineering. The tackifying resin comprises following components by weight: 30-53% of rosin, 1-1.5% of auxiliary agents, 5-18% of polyol, 5-20% of an emulsifier, 30-53% of water, 3-20% of styrene-isoprene-styrene segmented copolymer and 3-20% of styrene-butadiene-styrene segmented copolymer. Compared with the prior art, the initial adhesion and the holding power of the tackifying resin adopting a water miscible tackifying agent using the elastomer styrene-isoprene-styrene segmented copolymer and the elastomer styrene-butadiene-styrene segmented copolymer as tackifying substrates in the fields of tackifying and coating using are several times of those of common rosin type emulsion and polyacrylate emulsion tackifying agents. The waterproofness and the adhesion adaptability of the tackifying agent are significantly improved. The tackifying agent can significantly enhance the adhesive strength of emulsion adhesives.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a special tackifying resin for water-based PVC electrical tape and a preparation method thereof. Background technique [0002] After the 1980s, emulsion-type adhesives have been dominant in the adhesive industry. Since emulsion tackifiers can significantly improve the performance of emulsion adhesives and reduce the cost of adhesives, the development of emulsion tackifiers is very important for my country's adhesives. It is of great significance to the development of coating industry. With the continuous improvement of viscose and paint industry technology, the high performance requirements for water-soluble thickening products are getting higher and higher. Conventional modified pine perfume emulsion products can no longer meet the high-speed requirements of viscose, paint and ink industries. Development needs, at this stage, most of the domestic water-soluble tackifyi...
