Problems solved by technology

However, in the prior art, although the dispersibility of the anion powder is improved through surface modification, there is a problem that the coated surface modifier makes the pyroelectric and piezoelectric properties of the anion material decrease, so that the anion induces The ability to remove odor and formaldehyde is not high, and the modified negative ion powder still has the problem of sedimentation after being placed for a period of time, and its stability needs to be further improved

Abstract

The invention discloses an environment-friendly interior wall negative ion formaldehyde removal coating. The coating comprises the following components in parts by weight: 30-35 parts of water, 0.8-1part of a dispersing agent, 0.3-0.6 part of a defoaming agent, 0.1-0.3 part of a wetting agent, 0.2-0.4 part of a preservative, 0.5-0.8 part of a mildew preventive, 1-2 parts of an odor removal coalescing agent, 1.5-2.5 parts of an environment-friendly antifreezing agent, 18-25 parts of R706 titanium dioxide, 5-8 parts of kaolin, 3-5 parts of talcum powder, 10-15 parts of ground calcium carbonate,25-40 parts of odorless emulsion and 3-5 parts of modified negative ion powder. The coating has the following beneficial effects: the water-soluble odorless emulsion is used as a film-forming material, does not contain an organic solvent, and does not release any volatile organic compounds, and the coating is green and environment-friendly; the modified negative ion powder is added so that not only are better dispersion effect and stability achieved, but also the negative ion inducing capability is strong, and better odor removing and formaldehyde removing capabilities are achieved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly interior wall negative ion formaldehyde-removing coating and a preparation method thereof. Background technique [0002] In today's paint market, environmentally friendly and healthy odor-free products have become the main demand of consumers. [0003] Negative air ions are a kind of ions or ion clusters with floating points in the atmosphere. They have the functions of purifying the air, anti-oxidation, anti-aging, and eliminating free radicals in the body. They are called "air vitamins". Negative ion coatings have the effect of generating negative ions by adding powders with negative ion electric fields to the coatings. Negative ion paint has the function of environmental protection and health, mainly because the added negative ion material has a permanent electric field effect, which can generate negative ions, thereby increasing the concentration of ...
