Abstract

The invention relates to the technical field of building boards, and discloses a calcination-free board prepared from diatomite. The calcination-free board is prepared from the following raw materials in parts by weight: 40-60 parts of diatomite, 5-10 parts of silica fume, 5-15 parts of quick lime, 5-15 parts of bamboo and wood fiber, 2-6 parts of aluminum powder and 5-10 parts of water glass. The main steps comprise crushing, mixing, granulation, pressing, maintenance and polishing. The production process is compact in flow. Waste second-level and third-level diatomite is adopted as diatomite, the cost is low, waste utilization is achieved, aluminum powder serves as a foaming agent, water glass serves as an adhesive, the overall structure of the board is uniform, the second-level and third-level diatomite has many pores, the process does not have a calcination link, the pores cannot be damaged, and therefore the board body has certain adsorption capacity, the indoor humidity can be adjusted, indoor harmful gas can be removed, and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a calcination-free sheet prepared by using diatomite and a preparation method thereof. Background technique [0002] Plate is a flat rectangular building material plate made of standard size, used in the construction industry, used as a component of walls, ceilings or floors, and also refers to forged, rolled or cast metal plates; [0003] Plate is an essential component in the field of building decoration. With the development and progress of society, ordinary building plates can no longer meet people's needs. Ordinary plates have many disadvantages such as easy mold and poor corrosion resistance. Chinese patent CN107963880A discloses a A method for preparing a large-size multifunctional sintered diatom plate, the steps of which include: mixing of raw materials, granulation, molding, drying of the green body, and sintering of the plate, wherein the raw materials a...
