Anti-radon paint

Abstract

The anti-radon paint has the function of shielding and absorbing ray to lower the indoor radon density and avoid the harm of radon on human body. The present invention includes putty, primer and face paint, and features that the putty, the primer and the face paint include composite polymer latex, composite fiber, stuffing, anti-mildew agent, preservative, dispersant, rheologic agent, ARP5, ARG6 and ARB7 material.

Description

1. Technical field: [0001] The invention relates to an environment-friendly building material, in particular to a radon-proof coating for walls specially used for preventing indoor radon pollution of buildings. 2. Background technology: [0002] Radon is an inert gas, colorless and odorless. Radon is an internationally recognized carcinogen. Radon is one of the main pollutants in the indoor environment. Radon is listed as one of the main polluting gases in the indoor air control standards formulated by countries all over the world. Indoor radon pollution is common in high background areas. In the interior of concrete buildings in high-background areas, radon gas and radon daughters that exceed the standard are often released, as well as gamma rays, beta rays, X-rays, neutron rays, etc., especially when radon and radon daughters enter the human body. Further decay, releasing alpha rays and other rays, forming internal radiation. This long-term low-dose internal exposure is...

Problems solved by technology

The above-mentioned methods have certain problems to a certain extent, such as opening the doors and windows will waste energy, are vulnerable to mosquitoes, and are not safe. Installing ventilation pipes will also cause waste of energy and be attacked by mosquitoes. At the same time, the installation cost is high and frequent maintenance is required. , will also occupy a certain amount of indoor space; wallpaper has the problem of high price and cost and poor anti-radon effect; the reason why the successfully developed radon-proof coatings are difficult to popularize is that the price and cost are high and the effect of radon-proof is poor. There are problems such as poor environmental performance such as TVOC (total volatile organic compounds), high formaldehyde, and heavy metal content, as well as poor construction, low strength, and easy cracking; while the patent radon-proof mortar has a good radon-proof effect, but it still has a high price and cost. difficult to promote
