Radiation-resistant putty powder

Abstract

The invention discloses radiation-resistant putty powder which comprises the following raw materials in parts by weight: 30-50 parts of heavy calcium carbonate powder, 30-50 parts of ash calcium powder, 5-15 parts of hydroxypropyl methyl cellulose, 5-10 parts of lignocellulose, 0.5-2 parts of pigments, 1-5 parts of diatomite, 2-7 parts of light calcined magnesia, 5-10 parts of shielding materials and 5-10 parts of probiotics powder. The radiation-resistant putty powder is obtained by preparing the raw materials according to a formula and placed into a stirrer to be stirred and sealing in bags after being uniformly stirred, and is stirred with water when used. The putty powder disclosed by the invention ensures that the wall surface of a house has radiation-resistant capacity, can be used for effectively shielding the electromagnetic radiation source and is environmentally friendly, economic and affordable. According to the putty powder, the hydroxypropyl methyl cellulose and the lignocellulose play skeleton roles, so that the use intensity of putty is enhanced; and the diatomite and the light calcined magnesia have excellent moistureproof property and chemical resistant property, so that the wall surface has no scaling, no bulging, no desquamation and excellent abrasion resistance and washing resistance after the putty is brushed to an inner wall.

Description

technical field [0001] The invention relates to a putty powder for interior walls, in particular to a radiation-proof putty powder, which belongs to the technical field of chemical coatings. Background technique [0002] Putty is a kind of decorative coagulation material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. Applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. It is formulated with a small amount of paint base, a large amount of filler and an appropriate amount of coloring pigments. The pigments used are mainly iron red, carbon black, chrome yellow, etc. Fillers are mainly heavy calcium carbonate, talcum powder and so on. It can fill the partially sunken working surface, or scrape off the entire surface. It is usually applied to the surface of the primer layer after the primer layer is completely dry. It is required to have goo...
