Abstract

The invention relates to the field of the talc product for coatings, and in particular relates to modified talc for an interior decoration coating and a preparation method of the modified talc. The modified talc for the interior decoration coating is characterized in that the finished product is in the form of granular blocks having the whiteness of greater than or equal to 90% and the moisture content of less than 8%; the modified talc comprises the following mineral components by weight percent: 80-85% of natural talc, 7%-10% of aluminosilicate and 8-10% of modifier; the major ingredients include a hydrogen oxide, water-soluble acrylate and deionized water. Compared with the prior art, the modified talc for the interior decoration coating has the beneficial effects that 1) the modified talc is strong in hydrophily and is easily dispersed in the aqueous phase and the dispersion is low in viscosity and good in liquidity, and the modified talc is strong in adsorption capability and capable of effectively adsorbing and eliminating harmful gases such as formaldehyde in the air and the environment and converting the harmful gases into water and nontoxic substances; 2) automatic regulation of the environmental humidity is realized through automatic absorption and release of moisture content; 3) the dosage of the product in an aqueous-phase coating is 10-30%, and the modified talc has remarkable advantages such as stable suspension property and not-easy settlement.

Description

technical field [0001] The invention relates to the field of talc products for coatings, in particular to a modified talc used for interior decoration coatings and a preparation method thereof. Background technique [0002] Chemical name of talc: hydrated magnesium silicate; molecular formula: 3MgO 4SiO 2 ·H 2 O. Talc has the characteristics of low hardness, high whiteness, lipophilicity and hydrophobicity, lubrication, and flake particle shape similar to kaolin. It is often used as a functional filler in the coating industry. The specific steps of its conventional preparation method are to first pass the talc raw material through dry mechanical Crushing, and then through the particle size classification process, a powder product that meets the fineness requirements is produced. After the product is made into a coating, it has positive significance for increasing the sealing and fullness of the paint film, and can effectively reduce costs. [0003] But this dense structur...
