Problems solved by technology

These treatment agents based on silica powder as the matting component have a good matting effect, but there is a problem of dispersion of inorganic matting powder, and artificial leather is prone to white marks after folding and rubbing
It has been reported in literature (Yang Xiping: "Preparation and Application of Environment-friendly PVC Artificial Leather Matting Treatment Agent", Shaanxi University of Science and Technology, 2014) that two polymer emulsions that are thermodynamically incompatible are blended, and the film-forming surface of the blended emulsion produces microscopic defects. Undulating, resulting in a matting effect, but no practical product seen

Abstract

The invention relates to a water-based matting finishing agent used for surface treatment of artificial leather and containing no inorganic matting powder, and a preparation method thereof, wherein the water-based matting finishing agent comprises the components in parts by mass: 100 parts of an environmentally friendly acrylate resin emulsion or acrylate-styrene polymerized resin emulsion or their mixed emulsion with the solid content of 45% by mass, 90-300 parts of water, 0-1.5 parts of a film forming auxiliary agent, 1.5-5.0 parts of an acrylic copolymer thickener, 0.9-1.2 parts of a defoamer, 1.2-4.5 parts of a wetting agent, 0-5 parts of a functional auxiliary agent, and 2-5 parts of ammonia water with the content of 25%. The preparation method comprises the steps: under dispersing mixing, successively adding the components into a dispersion pot, stirring and dispersing evenly, filtering, and thus obtaining the water-based matting finishing agent. The matting finishing agent is environmentally friendly, has the advantages of good surface affinity to the artificial leather, strong adhesion power, no folded marks, good water resistance and strong matting effect. With use of different functional auxiliary agents, different impressions and handfeeling effects can be obtained.

Description

technical field [0001] The invention relates to an environment-friendly water-based matting finishing agent which does not contain inorganic matting powder and is used for surface treatment of PVC and PU artificial leather. The invention also relates to a preparation method of the matting finishing agent. Background technique [0002] PVC and PU artificial leather are the two most produced artificial leathers. The production process of PVC artificial leather is mainly coating method and calendering method. PU artificial leather is mainly produced by coating process. With the change of production raw materials and production technology, artificial leather products with different properties and varieties can be obtained to meet different application requirements. [0003] Due to the manufacturing process, the surface of artificial leather without surface treatment has a strong plastic feeling, which is quite different from natural leather in appearance. By adding gloss and...
