Problems solved by technology

However, artificial leather with high wear resistance and high waterproof for labor insurance on the market is mainly polyvinyl chloride artificial leather. Because this material has good air tightness, high density, and waterproof effect, it is relatively bulky, has a strong plastic feel, and has poor air permeability. The material needs to be added with some softeners, plasticizers, slippery agents, etc., and these substanc

Abstract

The invention relates to a method for manufacturing high wear-resisting and high waterproof polyurethane artificial leather for a safety and industrial costume, which comprises the following steps of: blending surface layer slurry containing polyester polyurethane, dimethylformamide, a flatting agent, a stripping auxiliary, a modified polysiloxane hydrocarbon antifoaming agent and a pigment; blending middle layer slurry containing waterborne polyurethane, water, a thickener and an antifoaming agent; blending adhesive coating slurry containing polyurethane, dimethylformamide, toluene, butanone, an accelerant and a cross-linking agent; and then carrying out a coating process. Solvent polyurethane resin and water-soluble polyurethane resin are cooperatively used; a dry coating production process is adopted; the product produced by the formulation technology has excellent wear resistance, waterproofness and ventilation property and is comfortable to wear.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing polyurethane artificial leather, in particular to a method for manufacturing polyurethane artificial leather with high wear resistance and water resistance suitable for labor protection clothing. 【Background technique】 [0002] In recent years, with the rapid development of the artificial leather and synthetic leather industry, products of various specifications have appeared on the market, and their uses are diversified, and they have been widely used in various fields of life and production. Due to market demand, the demand for high wear-resistant and high waterproof artificial leather products is increasing. However, artificial leather with high wear resistance and high waterproof for labor insurance on the market is mainly polyvinyl chloride artificial leather. Due to the material's good air tightness, high density, and waterproof effect, it is relatively bulky, has a strong plastic feel, and ha...
