Abstract

The invention provides an inorganic negative ion coating and a preparation method thereof. Special mica powder is added to a coating formula, so that the aims of releasing negative ions and not generating radiological hazards are achieved. Meanwhile, a sodium silicate solution is modified through zinc oxide and an organic silicon solution, so that a coating film has super-strong adhesion and hardness, fireproof and flame-retardant properties, water resistance, stability and high temperature resistance. The obtained coating does not contain an organic solvent or other toxic or harmful substance and is an environment-friendly product.

Description

Technical field [0001] The invention relates to inorganic coatings, belonging to the field of high molecular polymers, and in particular to inorganic negative ion coatings and a preparation method thereof. Background technique [0002] Negative ion coatings improve the living environment due to the characteristics of anion generation, and are favored by people, especially in cities with severe air pollution. People with strong health and environmental awareness are the first choice for decoration. In addition, the advantages of inorganic coatings such as high hardness, weather resistance, stain resistance, air permeability, fire resistance, flame retardancy, mildew resistance, and insecticide are favored by consumers. The raw materials used are rich in sources and low in price, so it has a broad market prospect. [0003] Water-based inorganic coatings are mainly silicates, which can be divided into potassium silicate, lithium silicate, sodium silicate and silica sol according to t...
