Abstract

The invention discloses a rubber-type pressure-sensitive adhesive applied to a surface protective film and a preparation method thereof. The rubber-type pressure-sensitive adhesive is prepared by blend refining, thin passing and sheeting natural rubber, an anti-aging agent BHT, a compounding agent, partial tackifying resin and partial vulcanizing agent and a rubber compound is obtained therefrom; at room temperature, a gasoline-ethyl acetate mixed solvent is added into an anti-explosion static-free stirring container; then the rubber compound, remained tackifying resin and vulcanizing agent are added; the container is closed; after even stirring and blending, the remained vulcanizing agent is added; and stirring and filtering are carried out again so as to obtain the rubber-type pressure-sensitive adhesive applied to the surface protective film. The rubber-type pressure-sensitive adhesive applied to the surface protective film can obtain appropriate initial adhesive performance, anti-stripping performance and anti-creeping performance by adjusting the usage of the vulcanizing agent and the adhesive, thereby realizing the balance among the three performances and overcoming the problems of bad keying strength and anti-aging performance and the like of a rubber-type pressure-sensitive adhesive.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive and a preparation method thereof, in particular to a rubber-type pressure-sensitive adhesive for surface protection film and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesives for surface protection films can be divided into four categories according to their forms: solvent-based pressure-sensitive adhesives, emulsion-type pressure-sensitive adhesives, hot-melt pressure-sensitive adhesives and radiation-curable pressure-sensitive adhesives; Divided into rubber-type pressure-sensitive adhesives, polyacrylate-type pressure-sensitive adhesives, thermoplastic elastomer-type pressure-sensitive adhesives, and other polymer series pressure-sensitive adhesives. Rubber-type pressure-sensitive adhesives have the characteristics of high cohesive strength, good elasticity and low-temperature performance, low surface energy, easy to infiltrate various solid surfaces, excell...
