Abstract

The invention relates to a water-based fog surface treatment agent for PVC leather and a preparation method thereof. Contains the following components: water-based polyurethane resin, water, silica matting powder, polysiloxane water dispersion, water-based wax emulsion, water-based wetting agent, water-based defoamer, thickener. The invention also relates to a preparation method of the water-based fog surface treatment agent for PVC leather. The water-based matte surface treatment agent for PVC leather disclosed by the present invention has good matte effect, good thick and heavy skin feel, stain resistance, water-based environmental protection, good adhesion, scratch resistance, twist resistance, and jungle resistance; Decoration, home appliances, furniture, automotive interiors, etc. have higher and higher requirements for skin feel and stain resistance.

Description

technical field [0001] The present invention relates to a surface treatment agent for PVC leather, in particular to a water-based matte skin-feeling treatment agent for PVC leather applied to the surface post-treatment process of PVC leather, and also relates to the water-based matte skin-feeling treatment agent for PVC leather. Preparation. Background technique [0002] PVC leather is light, water-resistant, and low-cost, so it is widely used in the production of clothing, shoes, hats, bags, furniture, decorations and various industrial accessories. Due to the addition of a large amount of plasticizers and other materials during the production of PVC artificial leather, the produced PVC artificial leather is not ideal in terms of gloss and feel. During the production process of leather, the surface treatment of leather must be carried out to give the leather surface a smooth, soft, matte and other comfortable feel, beautiful appearance, and anti-scratch, alcohol-resistant ...
