Problems solved by technology

[0003] Based on the function of negative ions to purify the air and promote health and the current situation of people's pursuit of healthy life quality, negative ion coatings are more and more recognized by people. However, although negative ion coatings on the market can effectively release negative ions, a large number of them are used When it comes to organic resins, it not only leads to high cost of use, but also the chemical properties of the coating are unstable, and the effect of wear resistance and heat resistance is poor; when this kind of coating is used, it takes a long time for the coating film to dry, which makes the construction period Too long; in addition, the surface properties and adhesion of the coating are poor

Abstract

The invention discloses an anion coating additive for removing formaldehyde and purifying air, and a preparation method and application of the anion coating additive. The anion coating additive for removing the formaldehyde and purifying the air is prepared from the following components in percentage by weight: 40-60% of base materials, 0.1-1% of a first dispersing agent, 0.1-1% of a first wettingagent, 20-35% of a first surfactant, 0.05-0.5% of a first defoaming agent, 0.1-1% of an anti-settling agent, 0.05-0.5% of a first preservative, 5-15% of a formaldehyde removing agent, and the balanceof water, wherein the base materials are prepared from the following components in percentage by weight: 20-35% of monazite powder, 30-45% of a compound containing rare earth, 0.1-1% of a second dispersing agent, 0.1-1% of a second wetting agent, 5-15% of a second surfactant, and the balance of water. The anion coating additive is scientific and reasonable in formula, zero VOC and zero formaldehyde are achieved, and heavy metal such as lead, cadmium, chromium and mercury is not contained; the removal rate of finished coating containing the coating additive to the formaldehyde in surrounding air can reach 95% or above, the finished coating has a long-acting removing effect on the formaldehyde, negative oxygen ions with high concentration, high vitality and small particle size can be released continuously, and the releasing number of anions is up to 9000/cm<3>.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anion coating additive for removing formaldehyde and purifying air, a preparation method and application thereof. Background technique [0002] With the improvement of people's living standards, the environmental protection requirements for the environment and daily necessities are getting higher and higher. The development of the coatings industry also tends to be environmentally friendly. People are paying more and more attention to the quality of indoor air. The first indicator to evaluate indoor air quality is the content of negative ions; negative oxygen ions are known as "air vitamins", which can be positively charged with dust, smoke, PM2.5, etc. in the air After the particles are combined, they settle to the ground, and can react with formaldehyde, benzene, TVOC and other decoration pollutants in the air, and decompose them into carbon dioxide and water, thereby puri...
