Abstract

The invention relates to a preparation method of an adhesive for shoe materials, and belongs to the technical field of shoe materials. According to the present invention, an aqueous polyurethane emulsion, an acrylate emulsion, an EVA emulsion, a butyronitrile emulsion, a chloroprene rubber emulsion, an epoxy resin emulsion and the like are mixed, and a surfactant is added to improve the interfacecompatibility between the aqueous polyurethane emulsion and the polymer emulsion to uniformly distribute the two components, such that the dried adhesive film is transparent, and is not easily cracked; according to the external cross-linking modification method of the present invention, the cross-linking modification is performed by using the epoxy resin coated curing agent, and a proper amount ofthe modified curing agent is added to the aqueous polyurethane main agent; the used curing agent is the polyisocyanate cross-linking agent, and when the polyisocyanate cross-linking agent is used, the active hydrogen on the surface of the bonding substrate can chemically cross-link with the -NCO group so as to effectively improve the bonding strength and the water resistance; and the epoxy resincoated polyisocyanate cross-linking agent is used for directly adding the curing agent during the preparation so as to ensure the storage stability of the adhesive for shoe materials.

Description

technical field [0001] The invention relates to a preparation method of an adhesive for shoe materials, and belongs to the technical field of shoe-making materials. Background technique [0002] The production of shoes is inseparable from the natural environment and human wisdom. In ancient times, due to the unevenness of the land and the severe cold and heat of the climate, human beings instinctively wanted to protect their feet, so shoes appeared. With the development of economy, footwear products have also made great progress, and various functional footwear, such as casual shoes, hiking shoes, sports shoes, etc., have appeared. [0003] Polyurethane adhesives have the characteristics of low temperature resistance, good flexibility, strong bonding performance and good flexibility and hardness, and their usage in the shoe industry is increasing year by year. Polyurethane adhesives in the domestic market are mainly solvent-based, and are prepared by solution polymerizatio...
