Problems solved by technology

[0003] Tackifying resin is usually one of the main components of adhesives, and its performance is directly related to the quality of the adhesive. Tackifying resins can be divided into two categories: solvent-based tackifying resins and water-based tackifying resins. Although solvent-based tackifying resins Relatively good properties such as durability and durability, but because the solvent contained in it is often harmful to human health, it is gradually abandoned in occasions with high environmental protection requirements; and the bonding of most water-based tackifying resin emulsions currently produced in China Relatively poor performance and dispersibility, so it cannot be widely used in occasions with high performance requirements

Abstract

The invention discloses water-based tackifier resin emulsion, which comprises the following raw materials in part by mass: 0 to 50 parts of modified abietic resin, 0 to 50 parts of liquid abietic resin, 0 to 50 parts of liquid terpene resin, 30 to 42 parts of water, 2 to 25 parts of dispersing agent, and 2 to 10 parts of surfactant. The modification of the abietic resin is realized by steps of disproportionation or hydrogenization of resin acid in the rosin and esterification or double bond addition by using polyatomic alcohol; and the mass parts of the modified abietic resin, the liquid abietic resin and the liquid terpene resin are not 0 at the same time. The prepared water-based tackifier resin emulsion has better adherence and dispersibility, is environment-friendly and has no harm toa human body.

Description

technical field [0001] The invention relates to a water-based tackifying resin emulsion and a preparation method thereof. Background technique [0002] With the development of science and technology, the application range of adhesives is becoming wider and wider: adhesives are needed in the bonding of cartons and cartons; the printed matter is coated with a film, and the film can be used without changing the original tone of the printed matter. It increases the luster and makes it more eye-catching, and is moisture-proof, anti-fouling, wear-resistant, etc., thus effectively protecting the inner layer, while the adhesive performance of the coating is directly related to the stability of the product; in the manufacturing process of automobiles, Due to the extensive use of composite materials and metal materials, the bonding strength between components determines the safety of the car itself. Therefore, the application of high-performance adhesives is indispensable. In addition...
