Negative ion induced powder, composition containing same and coating partner

Abstract

The invention relates to negative ion induced powder, a composition containing the same and a coating partner. The negative ion induced powder is prepared from the following components in percentage by weight: 20-35% of tourmaline, 27-34% of germanite, 33-43% of hexacyclic stone, and 3-5% of a lanthanide rare earth additive; and the grain diameter of the negative ion induced powder is 50 nanometers to 50 microns, and the negative ion release amount of the negative ion induced powder is 10000 to 50000 per cm<3>.s. The composition contains the negative ion induced powder and a porous material. According to the formulation provided by the invention, three natural minerals of the tourmaline, the germanite and the hexacyclic stone are adopted as main raw materials, meanwhile, the additive containing lanthanide rare earth is added, the natural minerals are activated, thus the negative ion release capacity of the formulation is improved, and accordingly, the negative ion induced powder can release a large number of negative ions under the situation of the small use amount.

Description

technical field [0001] The invention relates to the technical field of coating compositions, in particular to an anion-inducing powder, a purifying functional composition comprising the powder, and an anion-inducing coating partner comprising the composition. Background technique [0002] With the improvement of people's living standards, the effect of architectural decoration and decoration is more and more focused on luxury experience, but excessive decoration and unenvironmental furniture and building materials will cause indoor environmental pollution, and the released organic volatiles such as formaldehyde, benzene, ammonia and TVOC will pass through the respiratory tract When it enters the human body, it will have various adverse effects on the human body and seriously damage human health. According to the China Indoor Environmental Monitoring Center, the number of emergency visits caused by indoor air pollution in my country is 4.3 million each year, and the number of...

Problems solved by technology

But these two types of coatings also have certain shortcomings and problems.

Activated carbon, bamboo charcoal, diatomaceous earth and other porous materials in adsorptive functional coatings can indeed absorb harmful gases in a short period of time, but the biggest problem is that porous materials do not have the ability to decompose the adsorbed harmful substances. Adsorption, it is very easy to form a saturated state in about 15 days. After saturation, not only cannot purify the air, but also release the adsorbed harmful gas into the indoor air again, causing secondary pollution

Negative ion functional coatings do not have the problem of secondary pollution, but most of the commercially available negative ion coatings are directly added with negative ion-induced powder, which is easy to produce particles during stirring and adding, which not only affects the negative ion release of the coating, but also damages the film-forming material of the coating, causing The physical and chemical properties of the paint coating are reduced, which affects the quality of the paint

Moreover, due to the high density of powder induced by negative ions, it is easy to precipitate and harden after being added in the coating production process, which will affect the mixing uniformity of the coating.

At the same time, the pH value of the powder induced by negative ions is greater than 10, which is an alkaline substance, and it is easy to neutralize the paint emulsion and additives, causing the coating to return to halogen, affecting the appearance quality and service life of the coating.
