Problems solved by technology

[0003] At present, there are companies at home and abroad that use diatomite to add composite materials to manufacture various molding composition products, but there are still certain limitations in raw material formulations and manufacturing processes, which affect the application effect.
First of all, the diatomite molding composition must first be hot-pressed at a higher temperature, and then calcined at a high temperature to obtain the diatomite molding composition, so that the temperature has a greater adverse effect on the purifying agent, which not only reduces the diatomite molding The purifying effect of the composition, and make the cost of preparation higher; Secondly, the purifying agent for preparing the deodorizing diatomite composite material is mostly composed of tablet core and coating covering the tablet core, and the coating is mainly composed of nano-titanium dioxide, diatomaceous earth Composed of soil composite catalytic material and redispersible latex powder, the catalytic efficiency is low, which makes the moisture absorption and deodorization function and environmental purification function of the prepared diatomite molding composition weak

Abstract

The invention relates to a diatomite forming composition with hygroscopic and deodorization functions and a preparation method thereof. The diatomite forming composition is prepared from the following components in percentage by weight: 5% to 40% of diatomite, 5% to 20% of tourmaline powder, 1% to 5% of inorganic cleaning agent, 0.1% to 1.0% of acrylic resin adhesive, and the balance of gypsum powder; the inorganic cleaning agent is composite powder prepared by attaching precious metal catalysts to layered inorganic functional materials. According to the diatomite forming composition with the hygroscopic and deodorizing functions and the preparation method thereof, the diatomite forming composition can effectively eliminate harmful gases when the concentration of harmful aldehydes, ammonia and benzene gases is relatively low, instant effectiveness is good, and the purpose of purification in a short time can be achieved; the diatomite forming composition has a relatively strong adsorption capacity of moisture and a strong hygroscopic effect; the diatomite forming composition has a simple production process and a strong purification effect, and is easy to industrial production.
