Radiation-proof coating and preparation method thereof

Abstract

The invention proposes a radiation-proof coating and a preparation method thereof. The radiation-proof coating is prepared from the following raw materials in parts by weight: 8-12 parts of talcum powder, 8-12 parts of lime powder, 40-50 parts of porous starch, 8-12 parts of titanium dioxide, 8-12 parts of quartz powder, 35-45 parts of barium carbonate, 8-20 parts of epoxy modified silicone resin powder, 8-12 parts of styrene-acrylic emulsion, 0.8-1.5 parts of sodium polycarboxylate dispersant, 0.3-0.9 part of thickener, 0.1-0.5 part of defoamer, 0.8-1.2 parts of coupling agent and 40-70 parts of water. Compared with the prior art, the radiation-proof coating disclosed by the invention has the beneficial effects that the radiation-proof coating is safe and non-toxic, stable in performance, and easy to transport and store; the lead equivalent is 1.05 mmpb at least when the thickness of the coating achieves 10mm; the radiation-proof coating has strong absorbing ability on X and gamma rays, and is simple in preparation technology, and low in preparation cost; no secondary refraction is generated.

Description

technical field [0001] The invention relates to a paint, in particular to a radiation-proof paint and a preparation method thereof. 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 wall, but this will waste construction costs and occupy space, and the use of anti-radiation coatings on building walls is the most idea...
