Algae calcium compound material, decorative panel and production method

Abstract

The invention belongs to a building material and particularly relates to an algae calcium compound material, a decorative panel and a production method. Kieselguhr and a calcium-containing inorganic building material substrate are hydrated, gelled and compounded, thereby forming the algae calcium compound material, wherein the calcium-containing inorganic building material substrate is selected from one or more of hemihydrate calcium sulfate, calcium phosphate and calcium aluminate; preferably, the components are mixed at a weight ratio of the calcium-containing inorganic building material substrate to kieselguhr to enhanced fiber chopped strand to water-based gel solution to chemical auxiliaries being 100:(10-50): (1.2-2.0): (50-65): (5-10); and the raw materials are subjected to raw material pretreatment, mixing and stirring, filling and molding, maintaining and drying, and surface treatment, thereby forming a decorative material product. The excellent plasticity and environmental friendliness of the novel compound material are fully excited while the microporosity of the kieselguhr is utilized to endow the material with excellent functions of humidifying and absorbing harmful gas, such as, formaldehyde, and the like, and the environmental protecting functions, such as sterilization, and the like.

Description

technical field [0001] The invention relates to a building material, in particular to a calcium algae composite material, a decorative plate and a production method that utilizes the unique microporous characteristics of diatom material crystals and calcium sulfate (or calcium phosphate, calcium aluminate) crystal technology. Background technique [0002] The main component of diatomite is silicic acid, which has the characteristics of superfiber and porosity. When the indoor humidity rises, the ultra-fine pores of diatomite can automatically absorb the moisture in the air and store it to avoid indoor pollution. The environment is moldy and deteriorated. If the moisture in the indoor air decreases and the humidity drops, the diatomite wall material can release the moisture stored in the ultra-fine pores. Secondly, diatomite application research and experimental results show that diatomite can act as a deodorant, has the function of eliminating odor, decomposes harmful chemi...

Problems solved by technology

[0005] The technical solutions disclosed in the patent literature about diatomite and gypsum-based decorative building materials are: CN201502152U, CN201486076, and their common feature is that a single gypsum-based decorative plate is used as the base layer, and diatom mud is used as the finishing layer, that is, its diatom The soil wall material and the gypsum-based decorative board are formed by coating. There are limitations in product models, specifications, and patterns. The two are not integrated in technology. In terms of technology, there is secondary molding and long molding cycle due to the coating layer. At the same time, due to the potential of the interface layer Swelling and dissolution, low product performance and weather resistance

There are no reports in the literature on the microscopic crystallization technology of diatom, gypsum and other inorganic composite decorative building materials.
