Abstract

The invention belongs to the technical field of adhesive, and in particular relates to adhesive resin special for aluminum plastic pipes and a preparation method for the adhesive resin. The adhesive resin is characterized in that: the formula of the adhesive resin comprises the following components in part by mass: 10 to 15 parts of high-density polyethylene (HDPE), 30 to 40 parts of linear low density polyethylene (LLDPE), 0.05 to 0.25 part of dicumyl peroxide, 0.2 to 3 parts of maleic anhydride (MAH), 0.1 to 1 part of acrylic acid (AA), 5 to 10 parts of vinyl tri-methoxysilane or vinyl triethoxysilane, 1 to 5 parts of styrene butadiene styrene block copolymer (SEBS), 35 to 45 parts of tackifying resin, 15 to 20 parts of viscosity regulator, and 0.1 to 0.5 part of antioxidant. The grafted hot melt adhesive is prepared by adopting a melting method, so that many adverse factors during preparing the adhesive resin by adopting the conventional screw extruder are overcome. The adhesive resin obtained by adopting the method has good flow property, good high and low temperature resistance, durability and waterproof performance and excellent mechanical property, and has good adhesive performance on aluminum materials and polyethylene plastics.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a special adhesive resin for aluminum-plastic pipes and a preparation method thereof. Background technique [0002] The aluminum-plastic composite pressure pipe (referred to as the aluminum-plastic pipe) is constructed with a layer of polyethylene on the inner and outer walls, and a composite material pipe formed by five layers of hot melt adhesive and aluminum alloy in the middle layer. The aluminum-plastic composite pipe technology was patented by the British scholar KITI in the late 1970s. After 10 years of industrial research, it was first industrialized in Germany and the United Kingdom in the late 1980s. The biggest advantage of the aluminum-plastic composite pipe is that it combines the strengths of metal and plastic. It has the advantages of high and low temperature resistance, pressure resistance, corrosion resistance, light weight, high strength, and gas p...
