Purified and adsorbed composite diatom ooze powder coating and preparation and construction method thereof

Abstract

The invention discloses a purified and adsorbed composite diatom ooze powder coating and a preparation and construction method thereof, belonging to the field of building materials. The coating is prepared from the following components in parts by weight: 20 to 60 parts of diatomite with 600 to 1000 meshes, 10 to 50 parts of sea-foam stone powder with 325 to 500 meshes, 10 to 45 parts of dolomite powder with 600 to 1000 meshes, 10 to 40 parts of zeolite powder with 400 to 600 meshes, 2 to 20 parts of attapulgite powder with 800 to 1000 meshes, 10 to 45 parts of spinel powder with 800 to 1000 meshes, 1 to 15 parts of nanometer titania, 0.5 to 10 parts of negative ion powder, 0.2 to 5 parts of methylcellulose, 1 to 20 parts of re-disperse emulsion powder and 0.5 to 10 parts of 13x powder-like molecular sieve. According to the purified and adsorbed composite diatom ooze powder coating and the preparation and construction method thereof disclosed by the invention, the problems that an existing diatom ooze wall material is rough in texture, is difficult to be constructed on a large area, is low in construction speed and the like are solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a purified and adsorbed composite diatom mud powder coating and its preparation and construction methods. Background technique [0002] The main raw material of diatom mud is diatomaceous earth. Diatomite has a soft texture and is rich in a variety of beneficial minerals. Its particle surface has numerous tiny pores (the diameter of the pores is about 0.1-0.2 microns), which are regularly and neatly arranged in circular and needle shapes, and the porosity is as high as 90%. , the specific surface area is as high as 65㎡ / g. This unique molecular sieve structure determines its strong physical adsorption performance and ion exchange performance. Therefore, the use of diatom mud as a building wall material has the functions of purifying air, adjusting humidity, releasing negative oxygen ions, fire retardant, wall self-cleaning, sterilization and deodorization, etc., and is favored ...

AI Technical Summary

Problems solved by technology

Various fillers are usually used in existing diatom mud coatings to achieve multiple functions, but the selection of raw materials and proportions is not reasonable enough, which makes the existing diatom mud coatings generally rough in texture and difficult to construct in large areas. It is also difficult to increase the construction speed, and it is easy to cause color difference
