Problems solved by technology

It is used to replace wallpaper and latex paint, and is suitable for interior wall decoration of villas, apartments, hotels, homes, hospitals, etc. However, the materials used in diatom mud produced by many manufacturers are extremely unreasonable, and the surface area of ​​diatom earth is sealed. The performance of diatom mud is greatly reduced, and a more reasonable formula system is needed to develop diatom mud coatings, so as to provide people with better decorative materials

Abstract

The invention relates to ceramic powder capable of promoting blood circulation, killing bacteria and releasing far infrared rays. The ceramic powder is prepared by the following method: (1) preparingmixed granules: adding transition metal oxide, silicon dioxide, aluminum oxide, cerium dioxide and water into ball milling equipment, carrying out ball milling for 4-6 hours, adding discharged materials, and carrying out spray granulation to obtain granules with the particle size of 20 meshes and the water content of 10%+ / -2%; (2) conducting sintering: pressing the material particles in the step (1) into a plate through dry pressing under the pressure of 30MPa, then conducting calcining for 5-8 hours at the temperature of 1,400-1,500 DEG C in a tubular kiln in a weak reducing atmosphere, and then conducting cooling to room temperature to obtain a compact plate; and (3) conducting crushing: crushing the compact plate, carrying out ball milling with zirconium beads for 4-8 hours, and conducting sieving with a 1200-mesh sieve to obtain the ceramic powder capable of promoting blood circulation, killing bacteria and releasing far infrared rays. Cerium dioxide is converted into a Ce2O3 crystal phase in the weak reducing atmosphere sintering process, the crystal phases of different powder bodies are interspersed, and the ceramic powder capable of promoting blood circulation, killing bacteria and releasing far infrared rays is formed.

Description

[0001]The present invention is a divisional application of the Chinese patent "a two-component diatom mud water-based paint with zero VOC emission", the application date is November 10, 2018, and the application number is 201811335452.X.Technical field[0002]The invention belongs to the technical field of architectural coatings, and relates to a ceramic powder capable of promoting blood circulation, sterilizing and releasing far infrared rays and its application in diatom mud water-based coatings.Background technique[0003]With the rapid development of the national economy and the gradual improvement of people's material living standards, interior decoration has become increasingly popular.
