Problems solved by technology

The above-mentioned methods all have certain problems to varying degrees, such as opening 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), formaldehyde, and high content of heavy metals, as well as poor workability, low strength, and easy cracking; and although the above-mentioned patent radon-proof mortar has a good radon-proof effect, there are still relatively low prices and costs. Difficult to promote

Abstract

The invention discloses primer-free anti-radon interior wall putty powder and a preparation method thereof, and belongs to the technical field of coatings. The putty powder comprises the following components: white cement, silicon dioxide aerogel, activated nano calcium carbonate, superfine talcum powder, redispersible latex powder, superfine wood fibers, hydroxypropylmethyl cellulose, a powder defoaming agent, an organic silicon water repellent, tap water, polyacrylamide, polyvinyl alcohol resin, a dispersing agent, a defoaming agent, a bactericide, a coalescing agent and a high-hydrophobicity waterproof emulsion. The primer-free anti-radon interior wall putty powder can form putty with high strength and high compactness, has very good anti-radiation capacity, and can be used for shielding harm of radon gas in a wall body to human bodies for long, so that the concentration of indoor radon gas is less than 60 Bq*m for a long time and meets requirements of national GBZ / T155-2002.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a primer-free and radon-proof interior wall putty powder and a preparation method thereof. Background technique [0002] Radon is an inert gas, colorless and odorless. Radon is an internationally recognized carcinogen. Radon is one of the main pollution gases in the indoor environment. Radon is listed as one of the main polluting gases in indoor air control standards formulated by countries all over the world. Indoor radon pollution is widespread in high background areas. In high-background areas, there are often more than standard radon gas and radon progeny being released, as well as gamma rays, beta rays, X-rays, neutron rays, etc., especially radon and radon progeny entering the human body. Further decay, releasing Alpha rays and other rays, forming internal radiation. This kind of long-term low-dose internal radiation is quite dangerous, and thus endangers the human health in...
