Abstract

The invention provides a TPU (thermoplastic polyurethane) hot melt adhesive membrane. The TPU hot melt adhesive membrane is mainly prepared from the following raw materials in parts by weight: 100 parts of TPU, 30-50 parts of thermoplastic polyester of which the melting point is 90-105 DEG C, 10-30 parts of a tackifier, 5-25 parts of a filling material and 5-30 parts of a functional auxiliary agent. The hot melt adhesive membrane prepared by using the method provided by the invention is of a thermoplastic adhesive, is uniform in thickness and simple in bonding process, is suitable for bonding by adopting an automatic production line, is high in production efficiency and large in peeling strength after bonding, can resist water, heat and salt fog aging in an outdoor harsh environment, is durable in bonding, and can be used for significantly improving the bonding strength of the hot melt adhesive membrane adhered to fabrics.

Description

technical field

[0001] The invention relates to a TPU hot-melt adhesive film with a low melting point and high bonding strength and a preparation method thereof. Background technique

[0002] Hot melt adhesives currently used in the market include ethylene-vinyl acetate copolymer (EVA), polyamide (PA), copolyester (PET), polyethylene (PE) and polyurethane (PU). Melt adhesive pellets, hot melt adhesive powder, hot melt adhesive sticks and hot melt adhesive films, these hot melt adhesive products are widely used in industries such as automobiles, electronics, construction, light industry and textiles. For the bonding between materials in the form of large-scale lamination, hot-melt adhesive films are widely used due to their high efficiency and convenient construction.

[0003] Polyurethane hot-melt adhesive film has the advantages of convenient positioning and high peel strength. It is a hot-melt adhesive with excellent adhesion and sealing performance. It has developed rapi...
