Inorganic mineral interior wall coating and preparation method thereof

Abstract

The invention belongs to the technical field of wall decoration coatings, and discloses an inorganic mineral interior wall coating and a preparation method thereof. On the basis that the coating has interior wall decoration, even if the coating is detected under extremely strict detection standards, the precipitation amounts of VOC, free formaldehyde, volatile toxic gas and harmful heavy metals such as lead, chromium, cadmium and mercury are not detected, the internal and external irradiation indexes of the coating are 0.0 (+) according to radioactivity detection results, and the coating has A1-level fireproof performance, belongs to a healthy, safe and environment-friendly green low-carbon product, and is free of inhalation injury to human beings, especially beneficial to physical and psychological health of pregnant women, infants, children, old people and the like, and particularly suitable for hospitals, schools, offices, cinemas, closed environments, home decoration and the like. With the coating healthy, safe and environment-friendly living space is provided for a user, and carbon emission is reduced for China.

Description

technical field [0001] The invention belongs to the technical field of wall decoration coatings, in particular to an inorganic mineral interior wall coating and a preparation method thereof. Background technique [0002] At present, the wall decoration paints on the market are dominated by various latex paints, which play the function of beautifying the interior and exterior of the building, and at the same time, can also protect the main body of the building. [0003] After decades of practical application, latex paint products have exposed many environmental protection and safety problems. Standard measures for wall decorative coating products and applications have been introduced successively, and higher requirements and standards have been put forward for decorative materials, such as: (GB 50325-2020) "Indoor Environmental Pollution Control Indicators for Civil Construction Engineering"; (GB / T23991 -2009) "Determination of the Content of Soluble Hazardous Elements in Co...

AI Technical Summary

Problems solved by technology

In order to meet the environmental protection, health and safety requirements constantly raised by the country in the field of architectural coatings, some companies in the market have launched inorganic coatings one after another. However, due to the two major factors of technical bottlenecks and production processes, they are basically compound products (others) A certain proportion of artificially synthesized polymer emulsion is added to the film-forming substance of the paint), and only a few products can meet the above standards in terms of environmental protection, health and safety.

[0004] In the newly revised (T / CPCIF 0000-2021) "Technical Specifications for Green Design Product Evaluation-Inorganic Architectural Coatings" (draft for comments, not yet promulgated and implemented) on May 11, 2021, the environmental protection and health of inorganic coatings Safety and security have been greatly tightened and higher requirements have been put forward. Once the standard is promulgated and implemented, it will pose more stringent challenges to many coating companies
