Abstract

The invention relates to a wet polyurethane resin textile slurry, which comprises the following components: 2000-2500 parts of a polyester polyol mixture, 1500-1800 parts of diisocyanate, 300-450 parts of polyether diol, 230-280 parts of AS resin, a diol chain extender, 5000-8000 parts of DMAC, 10-13 parts of 2, 6-di-tert-butyl-4-methylphenol, 4-6 parts of dibutyltin dilaurate, 0.05-0.1Kg / 1000Kg a reaction termination agent, 20-30 parts of a cell regulator, and 3-8 parts of CA-630. Specifically, the molar ratio of the polyester polyol mixture to the diol chain extender is 1:1.5-2.0. The AS resin system introduced into the wet polyurethane resin textile slurry provided by the invention, the resin strength, air permeability and peeling properties of resin are improved, also the modulus is increased and the physical properties are improved, the cloth surface dryness and comfortability are improved.

Description

technical field [0001] The invention relates to the technical field of textile raw materials, in particular to an AS resin modified polyurethane resin textile slurry and a preparation method thereof. Background technique [0002] At present, in the fields of shoes, textiles, etc., genuine leather has good air permeability and soft touch, but its price is expensive and resources are limited, so it is the general trend to be replaced by synthetic leather. The production process of synthetic leather is divided into three steps: wet method, dry method and back-end treatment. Among them, the wet method produced by the wet method is the base material of synthetic leather, and the synthetic leather usually mentioned is the base material of the wet method. The surface is made by dry method and back-end treatment process. The impregnation process in the process of wet synthetic leather processing forms a large number of microporous structures on the back of the cloth base, making it ...
