Abstract

The invention provides a water-based environment-friendly coating material based on diatomite purification and titanium dioxide loading. According to the invention, diatomite is economically and effectively purified, and the purified diatomite loads nano titanium dioxide; by carrying out electron microscope standard on the diatomite before and after loading, the results show that the purity of diatomite is greatly improved; comparing the diatomite before and after loading by using an X-ray diffractometer (XRD), the results show that the nano titanium dioxide is already loaded in the pores of the diatomite; and the water-based coating material product prepared by purified diatomite loading the nano titanium dioxide can obviously improve the purification performance durability of toluene, and also has antibacterial function, mildew-proof function, anti-condensation function and other functions.

Description

technical field [0001] The invention relates to the field of building materials, in particular to the effective purification of diatomite, the preparation of loaded nano-titanium dioxide and the efficient adsorption and degradation of toluene water-based paint. Background technique [0002] Diatomaceous earth is a kind of sedimentary rock with unique biogenic microporous structure. It is a non-metallic mineral that is gradually formed by the natural environment through the deposition of the remains of diatoms that grow in oceans or lakes. It has the excellent properties of large specific surface area, strong adsorption, high porosity, high temperature resistance and stable chemical properties, and the physical properties of fineness, looseness, light weight, porosity, water absorption and permeability. The surface of diatomite generally has countless pores all over it, which has the functions of adjusting air humidity, absorbing and eliminating harmful gases and odors in the...
