Problems solved by technology

[0004] However, there are still some problems and room for improvement in the current commercially available Gangbao materials, because Gangbao materials are melted and processed from hot melt adhesive particles into hot-melt film for reuse. In order to pursue processing efficiency, the processing factory hopes that Gangbao materials can be formed as quickly as possible.
In addition, Gangbao also has the phenomenon of wrinkling during wearing or being deformed by high temperature, which not only affects the appearance of the shoes, but also causes problems such as uncomfortable wearing and grinding feet

Abstract

The invention discloses a rapid crystallization hot melt adhesive for a counter material and a preparation method of the rapid crystallization hot melt adhesive, and relates to the technical field of polyurethane hot melt adhesives. The hot melt adhesive is prepared from the following raw materials in parts by mass: 100 parts of polyester polyol, 2 to 5 parts of diisocyanate, 0.3 to 0.6 part of an antioxidant, 0.2 to 0.4 part of an anti-hydrolysis agent, 0.3 to 0.5 part of a light stabilizer, 0.2 to 0.4 part of a lubricant and 0.005 to 0.01 part of a catalyst, the polyester polyol is single polyester polyol or mixed polyester polyol, and the diisocyanate is single diisocyanate or mixed diisocyanate. The preparation method comprises the following steps: mixing the polyester polyol, the antioxidant, the anti-hydrolysis agent, the light stabilizer, the lubricant and the catalyst, heating, uniformly stirring, reacting with the diisocyanate, granulating, and drying to obtain the rapid crystallization hot melt adhesive for the counter material.

Description

technical field [0001] The invention relates to the technical field of polyurethane hot-melt adhesives, in particular to a rapid crystallization hot-melt adhesive for gang treasure materials and a preparation method thereof. Background technique [0002] As one of the most important materials for shoemaking, Gangbao is used in huge amounts every year. It is mainly used for shaping the front toe and heel of shoes. After shaping, the shape of the shoes is straight and round, and it is not easy to deform. The comfort and beauty of the shoes have been greatly improved. . [0003] Gangbao is divided into chemical film Gangbao (Shuigangbao) and hot melt glue Gangbao. Chemical film Gangbao is not environmentally friendly, it needs to be brushed to be compounded, and it is easy to deform. In the past, leather pulp Gangbao and chemical film Gangbao were used in shoemaking. , using water immersion softening method and soaking solvent (toluene) softening method, but the product is thi...
