Diatom mud and preparation method thereof

Abstract

The invention discloses diatom mud, which is prepared from the following raw materials by weight: 85-95 parts of diatomaceous earth, 5-8 parts of inorganic toner, 3-5 parts of food cellulose, 4-7 parts of inorganic rubber, and 8-12 parts of white sand. The invention further provides a preparation method of the diatom mud, wherein the preparation method comprises: (1) jet milling of diatomaceous earth, (2) screening of diatomaceous earth; (3) additive premixing; and (4) negative ion stirring. According to the present invention, the diatom mud is prepared by mixing the diatomaceous earth and theadditive, and specifically the screened diatomaceous earth is obtained by carrying out high-pressure jet milling and free fall screening on the diatomaceous earth, and the screened diatomaceous earthand the additive subjected to negative ion stirring to obtain the diatom mud; and the diatom mud is not easily blackened during the use, and the formed wall material has advantages of high quality, smooth surface, less fading and strong air purifying ability.

Description

technical field [0001] The invention relates to a diatom mud and a preparation method thereof. Background technique [0002] Diatom mud is a kind of interior decoration wall material with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, and fire and flame retardant. Diatoms are living in millions of years A single-celled aquatic plankton in the past, after diatoms die, it will deposit on the bottom of the water, and after hundreds of millions of years of accumulation and geological changes, it will become diatomite. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, It is also functional and is a new generation of decorative materials to replace wallpaper and latex paint. However, in the production process of the existing diatom mud, because the diatom earth is crushed by ball milling, it is easy to blacken during use and form The ...

Because diatom mud is healthy and environmentally friendly, it is not only very decorative, It is also functional and is a new generation of decorative materials to replace wallpaper and latex paint. However, in the production process of the existing diatom mud, because the diatom earth is crushed by ball milling, it is easy to blacken during use and form The quality of the wall material is poor, the surface is not smooth, it is easy to fade, and the ability to purify the air is poor
