A light-curing environment-friendly flexible PVC stain-resistant matte finish and preparation method thereof

Abstract

The invention belongs to the technical field of coatings, and specifically relates to a light-curing environment-friendly flexible PVC stain-resistant matte finish and a preparation method thereof. The matte finish is composed of the following components in parts by weight: silicone modified resin 20‑50 10-35 parts of polyurethane acrylate, 10-15 parts of acrylate monomer, 1-5 parts of anti-settling agent, 1-8 parts of dispersant, 3-8 parts of photoinitiator, 5-15 parts of matting agent, Leveling agent and defoamer 0.5-3 parts. The present invention uses organosilicon-modified resin as matrix resin, relies on the ultra-low surface energy of organosilicon, provides hydrophobicity for the coating film, and realizes good anti-staining effect. In addition, the organosilicon and main chain resin of the organosilicon-modified resin A strong chemical bond is formed between them, therefore, unlike the fluorosilicon additives, after long-term use, the fluorosilicon additives will be precipitated and the stain resistance of the coating film will be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a light-curing environment-friendly flexible PVC stain-resistant matte finish and a preparation method thereof. Background technique [0002] PVC material is a kind of plastic decoration material, which is the abbreviation of polyvinyl chloride material. PVC material has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardancy, and simple construction. There are many specifications, colors and patterns, and they are very decorative, and are widely used in various fields of production and life. In PVC artificial leather, flooring, wallpaper, tarpaulin, film and other daily necessities and industrial products, matte products are loved by many consumers.

AI Technical Summary

Problems solved by technology

[0003] At present, the matte coatings for PVC plastics generally have the following problems: (1) The traditional self-drying coatings have a long drying time and the physical and chemical properties of the paint film are poor; (2) the energy required for curing UV matte coatings is too high, and the The application on soft PVC that is susceptible to heat damage is limited, and the UV coating film is brittle, and the toughness cannot meet the requirements of soft PVC; (3) Most UV matte coatings have a certain matting effect, but matte coatings Unable to meet the user's expectation of stain resistance and easy cleaning
