Problems solved by technology

[0008] The purpose of the present invention is to provide a high-whiteness tourmaline negative ion powder and coating process, aiming to solve the problem of limited application of tourmaline due to its darker color. The solution is to use dry physical coating method to coat tourmaline Whitening modification, providing powder with high whiteness, high stability and tourmaline function, which can be used as a carrier of tourmaline to be coated on the inner wall to form a coating or paint or wallpaper, and can be released for a long time Healthy negative ions, absorb and degrade harmful gases such as formaldehyde, settle solid dust in the air, and release infrared rays to activate free water in the human body and improve human health

Embodiment Construction

[0025] Provide below the embodiment of the present invention (see attached table), and provide corresponding measured data [1] :

[0026] [1] Note in the table: In the examples, the particle size of the coating agent is ≤600nm. After the tourmaline ball mills to a particle size of 6-40μm, it is heat-treated in a muffle furnace at a calcination temperature of 300-750°C (1h of heat preservation); According to the requirement that the total weight of the prepared negative ion powder is 1.54Kg, the raw materials are weighed, the temperature of the cooling water in the cooling process is normal temperature, the stirring time in the subsequent stirring process is 3 to 6 minutes, and the particle size distribution of the obtained negative ion powder is D 97 =D 电气石 +1.75D 包覆剂 (error ±7%).

[0027] The particle size value indicated in [2] in the table is selected from D 97 .

[0028] [3] Coating strength test method in the table: After mixing the prepared negative ion powder with ...

Abstract

The invention relates to tourmaline negative ion powder with high performance and a coating process. The tourmaline negative ion powder comprises tourmaline, a coupling agent and a coating agent, wherein the occupied weight ratio of the tourmaline is 25-35%, the occupied weight ratio of the coupling agent is 1-3%, and the occupied weight ratio of the coating agent is 62-74%. The tourmaline negative ion powder is obtained by coating, whitening and modifying the tourmaline and can be used as stuffing powder for preparing a functional coating; and the tourmaline negative ion powder is directly doped in a water-based coating or is combined with a film forming material, pigment, an addition agent, a solvent agent and the like to prepare the functional coating. After forming the coating, the tourmaline negative ion powder can release lots of negative ions for long time, adsorbs and degrades indoor harmful gases, settle dust in the air and effectively improves indoor housing environments.

Description

technical field [0001] The invention relates to a high-performance tourmaline negative ion powder and a coating process. The negative ion powder is obtained by coating and whitening the tourmaline and modified. It can be used as a filler powder for preparing functional coatings and directly mixed into water-based coatings. The functional coating is prepared by neutralizing or combining with film-forming substances, pigments, additives, solvents, etc. After the coating is formed, it can release a large amount of negative ions for a long time, absorb and degrade indoor harmful gases, settle airborne dust, and effectively improve the indoor living environment. Background technique [0002] With the increasing demands of people on the quality of living environment, the demand for air purification is no longer simply to purify indoor air. For example, those who work in a closed air-conditioned room, because the dehumidification effect of the air conditioner makes the air in the ...
