Abstract

The invention provides an adhesive resin, which comprises high-density polyethylene, ethylene-vinyl acetate copolymer, low-density polyethylene, 1,1-bis-(t-butylperoxy)-3,3,5-trimethyl cyclohexane, 3,3,6,6,9,9-Hexamethyl-1,2,4,5-teraoxacyclononane, 2,5-dimethyl-2,5-bis (benzoyl peroxide) hexane and maleic anhydride. The maleic anhydride is grafted by adopting active grafting technology, and polarity function groups are grafted on polyethylene molecular chains. Compared with the prior art, the adhesive resin has the characteristics of being high in adhesion intensity, strong in adhesion durability, and strong in weather resistance and water resistance performance, and can be used for a glass filament winding reinforced polyethylene composite tube.

Description

technical field [0001] The invention relates to the field of adhesive compositions, in particular to an adhesive resin used for glass fiber winding reinforced polyethylene composite pipes and its preparation method and application. Background technique [0002] Glass fiber-wound polyethylene composite pipe (STSCP) is a network skeleton formed by high-strength glass fiber spirally wound left and right as a reinforcement, with high-density polyethylene (hereinafter referred to as HDPE) as a matrix, and a high-performance adhesive resin layer. The glass fiber mesh skeleton is closely connected with the inner and outer layers of high-density polyethylene. Therefore, the glass fiber winding reinforced polyethylene composite pipe is a very emerging composite pipe. Compared with traditional pipes, the cost is low and the pressure resistance level is high. It is widely used in water supply, gas transmission, chemical pipelines and other fields in the market. At the same time, the co...
