Problems solved by technology

In addition, it is difficult to achieve a high grafting rate during the melt grafting reaction, which is due to the existence of cross-linking side reactions in the grafting reaction, and the increase in the grafting rate will inevitably lead to an increase in the gel content, which seriously Affect the fluidity of hot melt adhesive

Abstract

The invention discloses a polyethylene hot melt adhesive composition comprising a base material, an initiator, a modifier, a graft monomer, a brightener, a viscosity regulator and an antioxidant, wherein the base material is formed by mixing high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE); the initiator is dicumyl peroxide (DCP); the modifier is one of an ethylene elastomer, petroleum resin or styrene elastomer; the graft monomer is a mixture of maleic anhydride (MAH) and acrylic acid (AA); the brightener is inorganic TiO; and the viscosity regulator is polyethylene wax. The hot melt adhesive has good compatibility, adhesive strength and heat stability with the base material.

Description

technical field [0001] The invention relates to a polymer composition, in particular to a graft type polyethylene hot-melt adhesive composition for aluminum-plastic composite pipes. Background technique [0002] Hot melt adhesive refers to an adhesive that is solid at room temperature, liquid when heated and melted, and can be bonded in a short time after coating, wetting, pressing and cooling. Hot melt adhesives mainly include polyethylene (PE) hot melt adhesives, ethylene / vinyl acetate (EVA) hot melt adhesives, polyamide hot melt adhesives and butyl hot melt adhesives according to their different uses. [0003] The aluminum-plastic composite pipe is composed of five layers: PE / hot melt adhesive / aluminum / hot melt adhesive / PE. Since the surface of the aluminum foil of the metal material mostly contains polar groups such as -OAI, -OH and -COOH, while PE is a non-polar substance, it is generally difficult to compound the two. Use maleic anhydride to graft and functionalize P...
