Abstract

The invention discloses a hot-melt reaction type polyurethane adhesive for compounding an electronic nylon film, and relates to the field of polyurethane adhesives. The hot-melt reaction type polyurethane adhesive comprises the following components in parts by mass: 23-27 parts of irregular reticular polyester polyol; 53-57 parts of polyether polyol; 44-48 parts of isocyanate; and 1-1.5 parts of asilane coupling agent, wherein the irregular reticular polyester polyol is formed by polymerization, esterification and polycondensation of 1,4-butanediol, 2-methyl propylene glycol, neopentyl glycoland adipic acid. By changing the molecular structure of polyurethane, the invention provides a polyurethane adhesive material which has favorable permeability and adhesive force for nylon materials,especially nylon films subjected to water-repellent agent treatment on the surfaces.

Description

technical field [0001] The invention relates to the field of polyurethane adhesives, in particular to a hot-melt reactive polyurethane adhesive for electronic nylon film compounding. Background technique [0002] Existing hot-melt reactive polyurethane adhesives for laminating electronic nylon films are mainly suitable for laminating common films, such as nylon without waterproof treatment or slight waterproof treatment. However, for the nylon film that has been treated with super water repellent on the surface, except for the products of a few foreign manufacturers, similar domestic products are difficult to meet the needs of use. The problem of not maintaining good adhesion in case of application. [0003] Under the trend of green, environmental protection and functional promotion of existing nylon films, domestic film suppliers are in urgent need of a domestically produced adhesive material with good water-repellent performance for production. Therefore, it has a good m...
