▎ 摘　　要

NOVELTY - Inorganic coating comprises the following components according to parts by weight is 40-60 pts. wt. silicate, 20-40 pts. wt. calcium carbonate powder, 10-30 pts. wt. silica sol, 5-15 pts. wt. talcum powder, 1-5 pts. wt. kaolin, 1-5 pts. wt. attapulgite, 1-5 pts. wt. aluminum oxide, 1-5 pts. wt. nano silicon dioxide, 1-10 pts. wt. modified tourmaline rare earth ternary composite material. The modified tourmaline rare earth ternary composite material comprises mineral carrier with adsorption and porous structure, tourmaline material, ternary composite catalytic material of rare earth oxide. USE - Inorganic coating with air purification function. ADVANTAGE - The inorganic paint increases the modified tourmaline rare earth ternary composite material and nano silicon dioxide, which can efficiently catalyze the generation of negative oxygen ion, improve the concentration of the negative oxygen ion, increase the utilization rate of the tourmaline rare earth ternary composite material, and efficiently purify the air environment. The inorganic paint is composed of natural inorganic material, no additive, non-toxic, formaldehyde-free, green, and environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the modified tourmaline rare earth ternary composite material, which involves: (A) preparing urea aqueous solution, mixing cerium nitrate and urea aqueous solution to obtain cerium oxide sol; (B) adding the tourmaline material into the cerium oxide sol, fully stirring and dispersing, at the same time, heating the temperature to 60-80 degrees C for heat treatment for 1-5 hours, drying to obtain the wrapped tourmaline rare earth composite material; and (C) adding the mineral carrier into the water to foam, adding the coated tourmaline rare earth composite material in the water environment, using ultrasonic to disperse, and performing heat treatment for 1-5 hours in the 60-80 degrees C, drying to obtain the modified tourmaline rare earth ternary composite material.
