Abstract

The invention relates to the technical field of adhesives, and in particular relates to a polyester hot-melt adhesive. The polyester hot-melt adhesive comprises polyester hot-melt adhesive resin, epoxy resin and curing agents, wherein the mass ratio of the polyester hot-melt adhesive resin to the epoxy resin and to the total amount of the curing agents is 70:(30-99):1. The polyester hot-melt adhesive is low in adhesive strength attenuation, so that the adhesive strength of the polyester hot-melt adhesive on metal can be obviously improved, the melting viscosity of the polyester hot-melt adhesive is reduced, and the film-forming appearance of the polyester hot-melt adhesive is improved; and moreover, the polyester hot-melt adhesive can be prevented from being hydrolyzed, high adhesion of the polyester hot-melt adhesive at low temperature, normal temperature even high temperature is kept, and the mass production property is high.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a polyester hot-melt adhesive and a coating method. Background technique [0002] Polyester hot-melt adhesive is a new type of non-solvent adhesive developed in the past ten years. It can be bonded only by heating and melting on the adherend, and it will be solidified and firm after cooling. Firmly stick to the sticky object. It does not need any solvent, fast bonding, easy operation, can simplify the bonding process, no pollution, no pollution, high bonding strength, wide range of uses, can bond rigid and flexible materials, and the production process is simple, raw materials are cheap and easy to get, and economic benefits high. [0003] At present, polyester hot melt adhesives are mainly used in the manufacture of adhesive interlinings in the clothing industry, the bonding of polyester films, the processing of non-woven fabrics, the bonding of leather outsoles in the shoem...
