Problems solved by technology

[0007] It can be seen from the above-mentioned representative documents that most of the existing production processes of diatom products adopt one-time sintering or non-firing without glazing treatment on the brick surface, which results in poor dirt resistance of the surface of diatom ecological bricks Difficult to clean after contamination
And the existing diatom ecological brick formula technology level is low, so it only has the function of adjusting indoor air humidity and absorbing formaldehyde

Abstract

The invention discloses a novel anti-fouling multifunctional microporous diatom ecological brick preparation method, which comprises: billet preparation, glaze preparation, billet granulation, billetmolding, billet drying and sintering, glazing, glaze surface baking, and secondary sintering. According to the present invention, the novel anti-fouling multifunctional microporous diatom ecological brick is prepared by using diatomaceous earth as the main raw material through high temperature firing according to the scientific ratio, wherein a large amount of nano-scale micropores exist in the diatomaceous earth, and can adjust indoor air humidity and adsorb harmful gases such as formaldehyde, benzene and the like, such that the diatom ecological brick prepared by the method has functions ofindoor dry and wet balance regulating, harmful gas absorbing and decomposing, negative oxygen ion releasing and the like, solves the problem of dirt intolerance and poor stain resistance of the products, and further has the improved decoration effect.

Description

technical field [0001] The invention relates to the technical field of decorative materials application, in particular to a preparation method of a novel antifouling multifunctional microporous diatom ecological brick. Background technique [0002] With the continuous improvement of people's living standards, the environmental protection of building materials has attracted more and more attention. Therefore, in recent years, many new interior decoration materials products with diatomite as the main raw material have emerged at home and abroad. Diatom ecological bricks It is one of the representative products. Diatomaceous earth itself is an excellent environmental protection material, and it has a large number of nano-scale pores. In addition to not containing any harmful substances, it can also adjust the indoor air humidity balance and purify the air. [0003] At present, similar diatom ecological brick products have appeared in the market, but because the diatom ecologic...
