Radiation protective paint

Abstract

The invention relates to the technical field of building paints, specifically to a radiation protective paint. The radiation protective paint comprises the following components: styrene-acrylic emulsion, a filler, modified metal powder, a wetting dispersant, a defoaming agent, an anticorrosive agent, a coalescing agent, an antifreezing agent, a flame retardant, hydroxymethyl cellulose and deionized water, wherein the modified metal powder comprises copper powder, aluminium powder, chromium powder, a nickle powder and silver powder; the material mesh number of the metal powder is 450-500 meshes; the filler is titanium dioxide or calcined kaolin; the wetting dispersant is an ammonium polyacrylate dispersant or an ammonium polyhydroxyate dispersant; the anticorrosive agent is potassium sorbate; and the coalescing agent is 2,2,4-trimethyl1-1,3-pentanediol monoisobutyrate. The flame retardant is a mixture which is obtained by mixing aimethyl methylphosphonate and triguaiacyl phosphate according to a mass ratio of 1:3. The radiation protective paint, provided by the invention, has the advantages of more outstanding radiation protective performance, good material stability, uniform material dispersion, uneasy layering, very smooth and delicate film layer and better weather resistance.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a radiation-proof coating. Background technique [0002] Coating refers to the general term for materials that are applied to the surface of objects and can form a tough protective film. Architectural coatings are an important category of coatings. In my country, they are generally used for interior walls, exterior walls, ceilings, floors, and toilets of buildings. Coatings are called architectural coatings. [0003] Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. It mainly includes the conceptual design of flat color, pattern and gloss and the conceptual design of three-dimensional pattern. However, it must be matched with the shape of the building...

But there are fewer types of coatings with radiation protection

Patent Publication No. CN105623325A discloses a fireproof and radiation-proof coating for thick steel structures. Materials such as graphene oxide are added to the coating to improve the radiation-proof performance of the coating. The production cost of graphene is relatively high, so in the current situation, it is not Has the value of large-scale promotion

Moreover, the scope of application of the coating is relatively narrow

[0006] Patent Publication No. CN101831211A discloses a sound-absorbing and anti-radiation coating and its preparation method. The coating not only has the excellent characteristics of general latex paint, but also has good sound absorption, seamless coating, super hiding power, The paint surface is smooth, smooth and comfortable to the touch, strong decorative, rich and bright colors, excellent leveling performance, easy to paint, strong alkali and mildew resistance, long-term use does not fade, good scrub resistance, but the radiation protection of the paint The performance is not very outstanding, and the radiation protection effect is limited
