Abstract

The invention discloses a kieselguhr-based composite material which is characterized by being prepared from the following components: crylic acid, methylcellulose, dodecanol, lauric acid, kieselguhr, peroxosulfuric acid, N,N'-methylene bisacrylamide. According to the kieselguhr-based composite material, the kieselguhr with high moisture releasability, an organic macromolecular material with high hygroscopicity and phase change materials such as dodecanol, lauric acid and thermo-sensitive polymer methylcellulose are combined and matched to prepare a novel composite material with two functions of adjusting the temperature and the humidity. The temperature and humidity adjustment effect of the composite material is good, and the maximum hydroscopicity and moisture desorption ratios are respectively 128 percent and 85 percent.

Description

technical field [0001] The invention relates to a diatomite, in particular to a diatomite-based composite material and a preparation method thereof. Background technique [0002] Diatomaceous earth is composed of amorphous SiO2 and contains a small amount of Fe2O3, CaO, MgO, Al2O3 and organic impurities. Diatomaceous earth is usually light yellow or light gray, soft, porous and light, and is commonly used in industry as insulation materials, filter materials, fillers, grinding materials, water glass raw materials, decolorizers, diatomite filter aids, and catalyst carriers. Wait. In recent years, diatomite is often used as an indoor humidity control material, but it is only limited to moisture absorption and humidity control, and has a single function. It caters to the market development of interior materials. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a diatomite-based composite material, through diatom...
