Abstract

The invention discloses diatomaceous earth putty powder and a preparation method thereof, and belongs to the technical field of environmental protection coating. The diatomaceous earth putty powder comprises the following raw materials according to the parts by weight: 8 to 25 parts of calcium hydroxide, 4 to 28 parts of white cement, 750 to 880 parts of ground calcium carbonate, 3 to 10 parts ofcellulose, 6 to 30 parts of dispersible latex, 8 to 25 parts of diatomaceous earth, 3 to 6 parts of antibacterial excipient, 3 to 6 parts of dispersant, 2 to 5 parts of defoaming agent, and 1 to 10 parts of pigment. The preparation method of the diatomaceous earth putty powder comprises the following steps of: firstly mixing the calcium hydroxide, the white cement, the ground calcium carbonate, the dispersible latex powder and the dispersing agent with deionized water, then adding the fermented diatomaceous earth and cellulose, and rare earth powder, afterwards adding the defoaming agent and the pigment, stirring successively and evenly, and finally freezing, heating and drying to obtain the diatomaceous earth putty powder. The diatomaceous earth putty powder prepared by the method has high-efficiency gas permeability and moisture resistance.

Description

technical field [0001] The invention relates to the technical field of environmental coatings, in particular to a diatomite putty powder and a preparation method thereof. Background technique [0002] Putty powder is a commonly used building decoration material, the main components are talcum powder and glue, and it is a base material for wall repair and leveling. It is made of inorganic gelling material as the base material, finely processed with bonding materials and other additives. It is an indispensable product before painting. It is applied on the primer or directly on the object. To remove uneven defects on the surface of the coated object. [0003] In recent years, the rapid development of my country's construction industry consumes a lot of construction resources. Moreover, indoor and outdoor decorative paints contain formaldehyde and a large number of bacteria, causing harmful substances such as building formaldehyde to exceed the standard seriously, endangering ...
