Liquid diatom radiation-proof paint

Abstract

The invention discloses liquid diatom radiation-proof paint. The liquid diatom radiation-proof paint is prepared by the following raw materials according to a weight proportion: 40-50% of compound amino acid kieselguhr, 10-20% of porous starch, 2-6% of starch ether, 5-20% of ash calcium powder, 20-30% of kieselguhr, 5-10% of bentonite, 20-30% of epoxy-modified organic silicon resin powder, 5-15% of quartz sand, 0.4-0.8% of thickener, 0.2-0.4% of defoamer, 1-3% of redispersible rubber powder, 1-3% of humectant, 0.6-1.8% of negative ion powder, 2-8% of water soluble fibers, and a suitable amountof water. The liquid diatom radiation-proof paint is simple in preparation, radiation-proof, economic and environment-friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a liquid diatom anti-radiation coating. Background technique [0002] With the development of society, more and more modernization, radiation technology is widely used in many fields such as national defense, medicine, industry, agriculture and so on. On the one hand, the application of radiation technology reflects the development of science and technology and economy, and on the other hand, radiation can cause varying degrees of damage to human health, especially X and gamma rays, which are the most widely used ionizing radiation and also endanger human health. the largest source of radiation. All of them have strong penetrating power and can pass through building walls of ordinary thickness. One of the ways to prevent radiation is to thicken the walls, but this will waste construction costs and occupy space, and the use of anti-radiation coatings on building walls is the most ideal w...

Problems solved by technology

One of the ways to prevent radiation is to thicken the walls, but this will waste construction costs and occupy space, and the use of anti-radiation coatings on building walls is the most ideal way

At present, lead plates, barium cement layers or composite protective plates are used for protection at home and abroad, but these materials have defects of varying degrees, such as poor adhesion, easy seams, easy cracks, easy to fall off, etc.

Most of the existing anti-radiation coatings and filled anti-radiation materials contain toxic substances exceeding the standard, such as formaldehyde, volatile organic compounds, lead, etc.
