Abstract

Improved indoor environment-friendly coating is prepared from the following raw materials in parts by weight: 40 to 60 parts of tailing powder, 0.2 to 1.5 parts of a photocatalyst, 7 to 8 parts of fillers, 5 to 10 parts of aids and 30 to 40 parts of water. The tailing powder serves as a base material, the tailing powder forms a porous shape after being heated and expanded, the pore diameter enables the air to pass through successfully and dust is blocked. The photocatalyst is added into the coating, so harmful gases such as formaldehyde and ammonia in the air and the coating can be decomposed. Meanwhile, staphylococcus aureus and klebsiella pneumonia in the air can be killed, the dust can be blocked out of the coating, and air circulation is formed to continuously decompose the harmful gases.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to coatings, in particular to an improved indoor environmental protection coating. Background technique [0002] Mineral resources are an important material basis of the national economy. With the acceleration of the industrialization process, the development of the national economy requires more and more energy and raw materials. As one of the pillar industries of the national economy, the mining industry is even more important, especially in my country's rapid development of the national economy. However, with the deepening of mines, the ore grade is declining, the amount of tailings and the corresponding investment are gradually increasing, and the recycling of tailings resources has become a major content of mining development. There are more than 400 tailing ponds in my country, directly polluting one million mu of land, and indirectly polluting about 10 million mu of land, and the an...
