Abstract

The invention discloses water-soluble PU nubuck low-temperature foamex for synthetic leather, prepared by the following raw materials in percentage by weight: 30-40 percent of water-soluble polyurethane, 40-50 percent of water, 2-10 percent of low-temperature nubuck foam powder, 2-5 percent of organosilicon levelling agent, 2-5 percent of organosilicon antifoaming agent and 0.5-2 percent of water-soluble polyurethane thickener. The mixture ratio of each component of the water-soluble PU nubuck low-temperature foamex for synthetic leather is scientific and reasonable, and the components mutually coordinate and jointly act. The nubuck low-temperature foamex has the advantages of good film reforming property and firm adhesion, and coating is resistant to solvent, cold, hydrolysis and thermalageing. The original effect of the leather surface of a finished product prepared from the water-soluble PU nubuck low-temperature foamex can not be influenced; after the leather surface is treated bythe foamex, low-temperature foaming is carried out to produce nubuck leather, and therefore, the effect of the leather surface is unique; moreover, the synthetic leather has exquisite texture, good air permeability and excellent resultant effect of hand feeling, water proofing, adhesion and the like.

Description

technical field [0001] The invention relates to a water-based PU yangbuck low-temperature foaming resin for synthetic leather, in particular to a water-based PU yangbuck low-temperature foaming resin for synthetic leather applied to the back-stage process of synthetic leather. Background technique [0002] With the improvement of people's living standards, people are gradually pursuing high-quality daily products, and the demand for leather products is increasing. With the enhancement of animal protection awareness, animal leather can no longer meet people's needs. At present, synthetic leather products have gradually become a popular trend in the future. Synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. The base fabric of PU leather is canvas PU material with good tensile strength. In addition to being coated on the base fabric In addition to the upper surface, the base fabric can also be included in the middle, so t...
