Problems solved by technology

Due to the heat dissipation of electrical appliances, if the heat dissipation is poor or the heating parts of the electrical appliances work continuously for a long time, the local temperature of the wall will be too high, resulting in the risk of melting and flowing of the adhesive bonding the wall covering and the wall, resulting in adhesive leakage Or the consequences of decreased bonding performance

Abstract

The invention discloses a hot melt adhesive membrane for cross-linking polyolefin wall cloth, and a preparation method of the hot melt adhesive membrane. The hot melt adhesive membrane comprises the following raw materials in parts by weight: 20-40 parts of maleic anhydride grafted polyolefin copolymer, 50-70 parts of polyolefin copolymer, 10-25 parts of ethylene-acrylic acid copolymer, 0.3-1 partof peroxide initiator, 0.5-1.5 parts of cross-linking agent, 0.3-1 part of maleic anhydride, and 0.2-1 part of antioxidant. The method comprises the steps of extrusion, granulation, and flow castingforming. The hot melt adhesive membrane for the cross-linking polyolefin wall cloth has physical and chemical bonding effects, and is high in bonding strength and excellent in thermal resistance at the same time; a risk of melting and flowing of the adhesive membrane caused by high temperature is avoided; and the problem in temperature adaptability of the hot melt adhesive membrane for the wall cloth is solved.

Description

technical field [0001] The invention relates to the field of hot-melt adhesive films for decorative materials, in particular to a hot-melt adhesive film for cross-linked polyolefin wall coverings and a preparation method thereof. Background technique [0002] Wall cloth is a kind of indoor wall decoration material. With the change of people's life philosophy, wall coverings are gradually replacing the paint and wallpaper used in traditional interior decoration. [0003] The traditional wall covering bonding process needs to use "cold glue" to bond the wall. "Cold glue" refers to glue used at room temperature, while "cold glue" for wall coverings is generally prepared from ready-made liquid glue or natural plant extracts prepared by chemical reagents. "Cold glue" for wall coverings has excellent bonding performance and flexible applicability, but there are also defects. For example, when "cold glue" is applied to seamless wall coverings, due to the overall construction, the...
