Abstract

The invention relates to an inorganic functional coating for degrading formaldehyde by negative ions and a preparation method of the coating. The coating comprises a component A and a component B, wherein the component A contains negative ion powder. The coating is high in abrasion resistance, hardness and high-temperature hot hardness, adhesive force and peeling strength and can be abraded for 9 hours, cross-linking density is greatly enhanced and compactness of the coating is increased as the coating is compounded with inorganic materials with different particle sizes, gaps among large-particle-size raw materials are filled up as the raw materials with different particle sizes are mixed, thermal stress dispersion among the large-particle-size raw materials is absorbed and buffered by small-particle-size raw materials, thermal stress concentration of the small-particle-size raw materials is resisted and isolated by the large-particle-size raw materials, the coating is environment-friendly and green, VOC (volatile organic compound) is avoided, a large number of negative ions can be generated, and the coating is superior to other products in the field.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an inorganic functional coating for anion-degrading formaldehyde and a preparation method thereof. Background technique [0002] As early as the 1970s, European scientists conducted a comprehensive and systematic study on the impact of indoor air and pointed out that among more than 500 organic substances detected from indoor air, there were more than 20 carcinogens. According to statistics in the World Health Organization's "World Health Report", nearly half of the world's people are exposed to indoor pollution. Patients suffering from respiratory diseases due to indoor environmental pollution account for 36% of the world's population, and chronic disease patients account for 23%. and lung cancer patients accounted for seventeen per thousand. The Indoor Pollution Detection and Observation Center of the China Interior Decoration Association has learned that among the many de...
