Abstract

The invention discloses organosilicone and polymerized rosin modified acrylate tackifying resin. The organosilicone and polymerized rosin modified acrylate tackifying resin is prepared from, by weight, 3-5 parts of homemade polymerized rosin tackifying resin, 140-155 parts of 2-ethylhexyl acrylate, 5-8 parts of methyl methacrylate, 45-54 parts of hydroxyethyl acrylate, 10-14 parts of methacrylic acid, 4-6 parts of alkylphenol ethoxylates (op-10), 0.3-0.5 part of organosilicone, 0.9-1.1 parts of a buffering agent, 3.5-4.5 parts of an inorganic initiator, 0.9-1.1 parts of a chain transfer agent and 240-260 parts of deionized water. The homemade polymerized rosin tackifying resin is prepared through the following steps that 7-10 parts of liquid abietate, 9-15 parts of glycerol ester of rosin and 5-8 parts of ethylene glycol monobutyl ether are added into a reactor, reaction is carried out for 2-3 hours at the temperature of 85-90 DEG C, and then the polymerized rosin tackifying resin is obtained. The invention further provides a preparation method of the organosilicone and polymerized rosin modified acrylate tackifying resin. By means of the preparation method, the indexes such as the initial viscous force, the opening time, the adhesive force, the peel strength, the stretching bonding strength and the thermal stability of the organosilicone and polymerized rosin modified acrylate tackifying resin can be improved at the same time.
