Indoor inorganic dry powder building coating capable of automatically regulating humidity

Abstract

The invention provides an indoor inorganic dry powder building coating capable of automatically regulating humidity. The components of the coating include inorganic cementing material, dispersible adhesive powder, porous adsorbing functional filler and conventional filler. The indoor inorganic dry powder building coating capable of automatically regulating humidity is dry powder, has excellent moisture absorption and moisture releasing functions, reaches the JC / T2082-2011 standard, has good humidity regulating property reaching I-grade standard requirement, also has excellent covering power, scrub resistance and storage stability, is convenient to transport, does not generate VOC, benzene, formaldehyde, heavy metals and other harmful substances when in use, and is convenient to produce and use and low in cost.

Description

technical field [0001] The invention relates to a coating, in particular to an inorganic dry powder architectural coating for indoor use which can automatically adjust humidity. Background technique [0002] Environmental protection in modern society has become a public topic. Compared with environmental protection concepts such as green pollution-free and sustainable development, humidity regulation is unfamiliar and often easily overlooked. In recent years, the role and harm of humidity have been paid more and more attention in China, so the research on humidity control and regulation has also been paid more and more attention. [0003] Air humidity is a physical quantity that expresses the amount of water vapor in the air, that is, the degree of dryness and humidity. Excessively high or low humidity affects the living environment and human health, and is seriously harmful to the preservation of items and the life of instruments. The harm is more serious when the humidit...

Problems solved by technology

[0005] The moisture absorption and release capacity of traditional coatings is limited, that is, the equilibrium moisture content is low, especially the moisture release capacity is weak

At the same time, there are also problems of slow moisture absorption and desorption, and poor durability and corrosion resistance.

For example, the 21-24 pages of the 9th issue of the 37th volume of the paint industry disclose a polyacrylate interior wall humidity-conditioning coating, which consists of polyacrylate resin, deionized water, dispersing wetting agent, leveling agent, defoamer, Composed of antifungal agents, the raw materials are easy to obtain, and the polyacrylate resin can absorb moisture to adjust the humidity, but the moisture absorption and release are very limited

[0006] The humidity-adjusting coatings currently used cannot effectively adjust the indoor humidity. Therefore, a coating with better moisture absorption and release performance is urgently needed
