Example Embodiment

[0026] Example 1

[0027] Mix 10% acrylate rubber, 10% polyethylene-acrylic acid, 30% chlorinated polyethylene, 20% rosin, and 30% calcium carbonate with a high-speed mixer and extrude at 150°C with an extruder Pelletizing, stretching, pulling, and winding through a casting machine to form a 0.15mm thick hot melt adhesive film. The 180° peel strength, water resistance, salt spray resistance, and weather resistance of the film to metal Al / Al, Cu / Cu, and stainless steel were investigated. The specific test results are shown in Table 1.

Example Embodiment

[0028] Example 2

[0029] Mix 20% of acrylic rubber, 30% of polyethylene-butyl acrylate, 20% of polymethyl methacrylate, 15% of maleic rosin, and 15% of white carbon black with a high-speed mixer. It is extruded and granulated at 180°C out of the machine, and then stretched, drawn, and wound by a casting machine to form a 0.15mm thick hot melt adhesive film. The 180° peel strength, water resistance, salt spray resistance, and weather resistance of the film to metal Al / Al, Cu / Cu, and stainless steel were investigated. The specific test results are shown in Table 1.

Example Embodiment

[0030] Example 3

[0031] Mix 30% polyethylene-acrylic acid, 30% polyethylene-methyl acrylate, 20% polyethylene-methyl acrylate-maleic anhydride copolymer, and 20% polyethylene with a high-speed mixer and extrude The machine is extruded and granulated at 150°C, and then stretched, drawn, and wound by a casting machine to form a 0.15mm thick hot melt adhesive film. The 180° peel strength, water resistance, salt spray resistance, and weather resistance of the film to metal Al / Al, Cu / Cu, and stainless steel were investigated. The specific test results are shown in Table 1.

Abstract

The invention provides a hot melt adhesive membrane for bonding a bi-metallic composite plate and a preparation method of the hot melt adhesive membrane. The adhesive membrane is prepared by the following steps: adopting one or several from polyacrylate rubber, polyethylene-acrylic acid (ester) copolymer or polyvinyl chloride-vinyl acetate esters copolymer as adhesive-based resin; adopting one or several blends from polyethylene, chloridize polyethylene, polyethylene-octene copolymer, ethylene propylene rubber, polyethylene-vinyl acetate, polymethyl methacrylate, polymethyl methacrylate-butadiene-styrene copolymer, polystyrene, thermoplastic polyurethane and polyvinyl chloride as a second matrix; adding a certain amount of thickening agents, fillers and functional additives after pre-mixing; and then casting to form the membrane. The hot melt adhesive membrane has high bonding strength and lasting stability, excellent weather resistance, aging resistance of salt mist, and water resistance, and is suitable for compounding and bonding of metal materials such as stainless steel, galvanized steel, iron, aluminum, copper, titanium alloys and the like.

Description

technical field [0001] The invention relates to a hot-melt adhesive, which belongs to the technical field of metal composite materials, in particular to a hot-melt adhesive film for bonding bimetallic composite boards and a preparation method thereof, which is mainly used in stainless steel, galvanized steel, iron, aluminum, Copper, titanium alloy and other homogeneous or dissimilar bimetallic plates are bonded and compounded. Background technique [0002] Layered metal composite material is a new type of material prepared by combining two or more metals with different physical, chemical and mechanical properties at the interface by using composite technology. The metal layered composite material formed by proper combination can greatly improve the thermal expansion, strength, fracture toughness, impact toughness, wear, electrical properties, magnetic properties and many other properties of a single metal material, so it has been widely accepted by countries all over the wor...
