Problems solved by technology

[0003] After searching the existing technical documents, it was found that Cang Fengbo mentioned an anion coating additive in "Application of Anion Additives in Coatings" (October 2004, Volume 34, No. 10 of "Painting Industry", which consists of a variety of natural Minerals are made by scientific proportioning, and the negative ion concentration of the room painted with negative ion latex paint can increase by 500-1200. Radiation, again, is very harmful to humans

Abstract

The present invention belongs to an internal wall paint with the functions of removing formaldehyde, resisting bacteria and resisting electromagnetic radiation. Its composition includes (by wt%) 1.5-3% of titanium dioxide nano-grade micropowder, 1-3% of silicon dioxide nano-grade micropowder, 0.5-1.5% of zinc oxide micropowder, 2-4% of negative ion micropowder, 1-2% of inorganic anti-bacterial micropowder, 5-8.5% of conductive micropowder, 1-2% of manganese-iron micropowder, 17-23% of film-forming component, 10-15% of pigment self-body, 16-18% of adjuvant and 20-45% of water.

Description

technical field [0001] The invention relates to a coating belonging to the technical field of materials, in particular to a formaldehyde-removing, antibacterial and electromagnetic radiation-resistant interior wall coating. Background technique [0002] The pollution of indoor decoration materials and furniture is the main aspect of indoor air pollution at present. Materials such as paint, plywood, shaving filler, interior wall paint, and plastic veneer all contain organic vapors such as formaldehyde, benzene, ethanol, and chloroform. quite carcinogenic. Investigations by specialized agencies in the United States and Japan have found that the indoor air pollution procedures of many civil and commercial buildings are 2-5 times that of outdoor air pollution, and about 30% of the living rooms cause "new home syndrome" due to the use of harmful chemicals. In addition, various electromagnetic waves of different wavelengths and frequencies are generated when office automation equ...
