Odor-removing anticorrosive finishing paint coating and preparation method thereof

Abstract

The invention discloses an odor-removing anticorrosive finish paint coating. The coating comprises the following components in parts by mass: 30-35 parts of water, 0.8-1 part of a dispersing agent, 0.3-0.6 part of a defoaming agent, 0.2-0.5 part of a wetting agent, 0.2-0.5 part of a preservative, 0.5-0.8 part of a mildew preventive, 1-2.5 parts of an odor-removing coalescing agent, 1.8-2.5 parts of an environment-friendly anti-freezing agent, 20-25 parts of R706 titanium dioxide, 4-8 parts of kaolin clay, 3-5 parts of talcum powder, 8-15 parts of heavy calcium carbonate, 27-40 parts of odor-removing emulsion, 2-3 parts of TiO2-loaded composite photocatalytic material, and 3-5 parts of modification negative ion powder. The invention has the following beneficial effects: the added modification negative ion powder not only has good dispersion effect and stability, but also has strong negative ion inducing ability, and has good odor removal and formaldehyde removal ability; the TiO2-loadedcomposite photocatalytic material is added, so that the prepared coating has a photocatalytic effect, organic pollutants attached to the surface of the coating can be degraded, and a coating layer has a self-cleaning function; and meanwhile, natural diatomite is used as a carrier, a porous structure is provided, and formaldehyde and volatile organic compounds in air can be adsorbed, so that the photocatalytic effect is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an odor-cleaning anti-corrosion finish 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. At present, there are two main principles of "purifying odor" in the market: the first technology is to cover the smell of emulsion with essence. Odor masking does not mean that the smell is eliminated, so in addition to smelling the scent of the essence, the user is also unknowingly hurt by the smell of the paint. Therefore, it is a "pseudo cleansing" technology, and it cannot even be called a technology, but an illusion. Because of its lower price, it is selected by most consumers, which not only fails to achieve the purpose of health, but also increases the harm to the health of consumers. [0003] The second technology, that is, the emulsion ...

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
