Abstract

The invention relates to a purification coating as well as a preparation method and application thereof. According to the purification coating disclosed by the invention, the potassium silicate solution is used as an inorganic binding material, the porous adsorbent is used as an adsorbent, and binding can be realized in a discontinuous film forming manner, so that the porous structure of the powder raw material is kept to a greater extent, the specific surface area of the coating is increased, and the purification effect of the coating is finally improved. The invention further provides a preparation method of the purification coating and a purification coating, the purification coating is bonded in a discontinuous film forming mode, after the coating is hardened during construction, the porous structure of the material can still be reserved, and the coating is a water-based coating which is resistant to water, resistant to scrubbing, super-strong in mildew resistance and high in purification effect and is especially suitable for coating of an inner wall.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and particularly relates to a purification paint and a preparation method and application thereof. Background technique [0002] Porous materials are widely used in the field of air purification because of their large specific surface area and suitable pore size distribution, which can effectively adsorb harmful gases such as formaldehyde through physical adsorption, chemical adsorption, etc. [0003] As an adsorbent, porous materials have been widely used in coatings to prepare functional coatings with air purification functions. In the related art, dry powder purification coatings, such as diatom mud products, are added to the wall by adding inorganic adhesive materials (such as lime calcium, cement, gypsum) and a very small amount of glue powder, and then applied to the wall after mixing with water. The water volatilizes and bonds with each other to form a discontinuous and incomple...
