Abstract

The invention relates to an aqueous matt surface finishing agent for PVC (Polyvinyl Chloride) leather and a preparation method thereof. The aqueous matt surface finishing agent is prepared from the following components: aqueous polyurethane resin, water, silicon dioxide matting powder, polysiloxane water dispersoid, aqueous wax emulsion, an aqueous wetting agent, an aqueous de-foaming agent and a thickening agent. The invention further relates to a preparation method of the aqueous matt surface finishing agent for the PVC leather. The aqueous matt surface finishing agent for the PVC leather, disclosed by the invention, has an excellent matt surface effect, a good heavy and skin feeling and a pollution-resisting performance and is aqueous and environment-friendly; meanwhile, the aqueous matt surface finishing agent has the advantages of good adhesive force, scratching resistance, bending resistance and forest resistance, and can meet the higher and higher requirements on skin feeling and pollution resistance of home decorations, electric appliances, furniture, automobile interiors and the like.

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 ...
