Problems solved by technology

Although the protective layer made by this method can partially block and shield ultraviolet rays, it cannot achieve a complete ultraviolet shielding effect because the mineral particles cover the surface of the adhesive layer and cannot achieve 100% continuous coverage.

Abstract

The invention discloses a weather-resistant coating and a preparation method thereof. The weather-resistant coating comprises the following components in parts by weight: 10-40 parts of water, 10-50 parts of an acrylic acid emulsion, 20-70 parts of packing, 0.1-1 part of an ultraviolet absorbent, 1-30 parts of nano zinc oxide, 0.1-5 parts of a dispersing agent, 0.1-5 parts of a wetting agent, 0.5-5 parts of a defoaming agent, 0.1-5 parts of a leveling agent, 0.1-5 parts of a thickening agent and 0.1-5 parts of a preservative. The invention further discloses a preparation method of the weather-resistant coating. By adopting the weather-resistant coating, the ultraviolet light shielding property of a coated layer can be protected, meanwhile, the density of the coated layer can be greatly increased, the water resistance property of the coated layer can be improved, and thus the water movement prevention property of a pre-installed and inverted adhered waterproof roll can be improved; and in addition, the tensile strength and break elongation of the coated layer can be remarkably improved, and thus the waterproof property of the pre-installed and inverted adhered waterproof roll can be improved.

Description

technical field [0001] The invention relates to a weather-resistant coating and a preparation method thereof, in particular to a weather-resistant coating for pre-laying a protective layer of an anti-adhesive waterproof coil and a preparation method thereof. Background technique [0002] Since it was introduced into the Chinese market in the 1990s, the pre-laid anti-adhesive waterproof membrane has developed rapidly in China due to its excellent anti-channeling performance, and has been widely used in underground projects, open-cut tunnel projects, and underground tunnel projects. Key projects such as underground pipe gallery waterproofing works. The typical structure of pre-laid anti-adhesive waterproof membrane includes the main waterproof layer, adhesive layer and protective layer. The main function of the protective layer is to protect the adhesive layer from external pollution, isolate ultraviolet rays and oxygen environment, and protect the adhesive layer. Chain sciss...
