Wall paint with radiation protection and corrosion resistance

Abstract

The invention relates to the technical field of building paint, in particular to wall paint with radiation protection and corrosion resistance. The wall paint comprises the following ingredients: water-based polyurethane-acrylate emulsion, organic silicon resin, titanium dioxide, enveloped metal micropowder, graphene, a pigment, a wetting dispersing agent, a silane coupling agent, an isocyanate curing agent, dimethythiotoluene diamine, a defoaming agent, a film formation assistant and an ultraviolet absorber. The wetting dispersing agent is an ammonium polyacrylate dispersing agent or a polyhydroxy acid ammonium dispersing agent; the defoaming agent is an organosilicon defoaming agent; the film formation assistant is texanol; and the ultraviolet absorber is phenyl salicylate or 2-hydroxyl-4-methoxy benzophenone. The paint has relatively excellent radiation protection performance and very excellent corrosion resistance and water resistance.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a wall coating with radiation-proof and corrosion-resistant properties. 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 m...

[0005] 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

[0006] Patent Publication No. CN104650660A discloses a raw material composition of an interior wall anti-radiation coating, in which materials such as metal-plated fabrics, metal fiber imitation fabrics, multi-ion fabrics, and stainless steel fiber slivers are used to improve the anti-radiation performance of the coating. However, the material used in the coating has poor corrosion resistance

[0007] In fact, coatings that achieve radiation protection performance by adding metal products have such problems, because these metals such as Fe, Al, Zn, Mg are easily oxidized and corroded under acid, alkali or strong oxidizing conditions, thereby reducing the chemical properties of the coating. stability and cause the coating to lose its radiation protection properties

If metal materials such as Au, Pt or Ag with relatively low activity are used for addition, the cost of the coating will be too high to be of practical value
