Abstract

The invention provides an uvioresistant coating for fabrics. The uvioresistant coating is prepared from the following components in parts by weight of 55-65 parts of epoxy resin, 2-4 parts of a coalescing agent, 0.5-1.5 parts of a thickening agent, 12-18 parts of titanium dioxide, 6-9 parts of zinc oxide, 0.5-1 part of a defoaming agent, 1.5-3 parts of a dispersing agent and 9-13 parts of Tinuvin477. The coating prepared by the invention has good adhesive force on the surface of the fabric, has good sunlight refraction and absorption effects, and particularly has excellent ultraviolet resistance.

Description

technical field [0001] The invention relates to a coating, in particular to an anti-ultraviolet coating for fabrics. Background technique [0002] The ozone layer can reduce the exposure of ultraviolet rays in sunlight to the surface and protect organisms from excessive ultraviolet radiation. With the extensive use of refrigeration equipment, the news that a large number of Freon emissions have caused the hole in the ozone layer in the atmosphere has repeatedly appeared in TV news. The destruction of the ozone layer makes people face the danger and distress of excessive ultraviolet radiation. Excessive ultraviolet radiation can cause skin erythema or sunburn, pigmentation, skin aging and even skin cancer. As people's awareness of the dangers of excessive UV rays grows, leading to an increasing demand for fabrics with UV protection, such as clothing, umbrellas, etc., it appears that the development of a UV-resistant coating for plants necessary.
