Environmentally-friendly ultraviolet resistance coating

Abstract

The invention discloses an environmentally-friendly ultraviolet resistance coating. The coating is prepared by using the following raw materials, by weight, 4-6 parts of a dispersant, 3.4-5 parts of organic acid phosphate, 3.7-5.4 parts of tin oxide, 2.5-3 parts of pentaerythritol tetracrylate, 0.3-0.8 parts of barium sulfate, 5.5-7 parts of an emulsion, 2.3-3.4 parts of isobornyl acrylate, 0.4-0.7 parts of a thickening agent and 0.1-0.2 parts of a filler. Compared with coatings in the prior art, the coating produced through an environmentally-friendly ultraviolet resistance coating formula provided by the invention has the characteristics of a general ultraviolet light-curable coating, gives a product with a profound layering sense and special glossiness, and has the advantages of improved ultraviolet resistance and stability, non-toxicity, environmental protection, production cost reduction, suitableness for industrial production, prolonged service life, good environmental protection performance and easy popularization application.

Description

technical field [0001] The invention relates to a coating, in particular to an environment-friendly anti-ultraviolet coating, which belongs to the field of coatings. Background technique [0002] With the enhancement of people's awareness of environmental protection, the application of water-based exterior wall coatings is becoming more and more extensive. Among them, styrene-acrylic exterior wall coatings are favored for their excellent water resistance, alkali resistance, scrub resistance and relatively moderate price. However, styrene-acrylic exterior wall coatings have phenomena such as fading, falling off, and powder falling during long-term use, which limits the development of styrene-acrylic coatings as exterior wall coatings. The main cause of these problems is the destructive effect of ultraviolet rays in sunlight, especially short-wave ultraviolet rays with a wavelength of 200-280nm and mid-wavelength ultraviolet rays with a wavelength of 280-320nm are the most de...

Problems solved by technology

The solution is to add additives with anti-ultraviolet properties to the paint. Most of the anti-ultraviolet additives in the past are organic substances, such as salicylate series, benzophenone series, benzotriazole series, etc. These additives have certain toxicity, and its absorption of ultraviolet rays has a certain selectivity; at the same time, with the prolongation of use time, its anti-ultraviolet ability will gradually weaken until it fails
