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.
Due to the strong hygroscopic function of the diatomite molding composition, the outer surfaces of various products made of the diatomite molding composition are prone to breed various bacteria, which is not conducive to keeping the surface of the diatomite molding composition product clean

Abstract

The invention discloses a diatomite forming composition with the moisture absorption function and a preparing method thereof. The diatomite forming composition is prepared from diatomite, tourmaline powder, zeolite powder, bamboo charcoal, antibacterial agent, acrylic resin adhesive and gypsum powder. The added antibacterial agent is an inorganic antibacterial agent obtained in the mode that a silver ion is attached to glass, and the inorganic antibacterial agent is high in safety, free of resistant bacteria and remarkable in antibacterial effect; when the antibacterial agent is prepared, metallic silver and the glass are mixed evenly under the high-temperature oxygen-free condition, and it can be avoided that the metallic silver is oxidized; when the antibacterial agent is prepared, a molten mixture is put into the low-temperature oxygen-free environment and cooled to the room temperature, the hardness of the antibacterial agent prepared with the method can be improved, the roughnessof the surface of the antibacterial agent is increased, and the falling-off phenomenon of the antibacterial agent is reduced; the tourmaline powder with the proper ratio and the zeolite powder with the proper ratio are added and can effectively excite negative oxygen ions in the room environment.

Description

Technical field [0001] The invention relates to the technical field of preparation and application of diatomite-based composite materials, in particular to a diatomite molding composition with moisture absorption function and a preparation method thereof. Background technique [0002] Diatomaceous earth is a kind of porous biological siliceous rock formed through preliminary diagenesis after the remains of ancient single-celled lower plant diatoms are deposited and deposited. It is composed of diatom wall shells with multi-level, large number of micropores arranged in an orderly manner, and diatomaceous earth has low density, large specific surface area, good adsorption, acid resistance, alkali resistance, insulation, etc. Characteristics, its unique surface structure and excellent adsorption performance are suitable for use as adsorption materials, and China's diatomite mineral resources are abundant, cheap and easy to obtain. Diatomite is composed of amorphous SiO 2 Compositio...
