A photocatalytic inorganic ecological decorative plate and its production method

Abstract

The invention discloses a photocatalytic inorganic ecological decoration board and a production method thereof. The photocatalytic inorganic ecological decoration board is characterized by being prepared from the following raw materials in parts by weight: 1.0-8.0 parts of pore forming photocatalytic materials, 100 parts of inorganic ecological gelatinization powder, 1.5-20 parts of reinforced fibers and / or glass fiber gridding cloth, 0.3-5.0 parts of a hydrophobic waterproof agent and 18.5-68.0 parts of liquid mediums. Processes of photocatalytic loading, inorganic ecological gelatinization powder pretreatment, mixing, pouring or pressing or extruding or jetting forming, maintenance drying and surface treatment are carried out on the raw materials to prepare ecological series decoration boards which can be widely applied as materials such as ceilings, wallboards, floors and outer curtain walls; besides the infinitely plastic decoration expressive force and excellent mechanical property, the decoration boards have the ecological functions of air purification, antibiosis, mould prevention, antifouling and self-cleaning.

Description

technical field [0001] The invention relates to the field of decorative building materials, in particular to a photocatalytic ecological decorative board capable of decomposing environmentally harmful gases, antibacterial, antifungal, antifouling and self-cleaning under light conditions and a production method thereof. Background technique [0002] Since the discovery of irradiated TiO by Fujishima et al. in 1972 2 Since the continuous redox reaction occurs on the surface, photocatalytic technology has been shown to be the most effective way to degrade volatile harmful gases in indoor air, and at the same time decompose surface-attached microorganisms and super-hydrophilic effect to reduce the adhesion of organic dirt on the surface of building materials , so as to reduce environmental harmful gas pollution, antibacterial and antifouling purposes. [0003] In Japan, the photocatalysis or photocatalyst market reaches more than 200 billion yuan every year, and grows at a rate...

AI Technical Summary

Problems solved by technology

[0010] In the technical scheme related to photocatalytic technology and inorganic decorative materials, CN103011684A discloses a diatomite-based functional decorative wall brick that can breathe and self-clean and its production method. The catalyst solution is obtained by drying and roasting, and there are problems of uneven dispersion and low value-added utilization of nano-based titanium dioxide composite photocatalysts

In order to endow the existing gypsum-based, cement-based, inorganic mineral-based and other inorganic decorative ceilings, wall panels, floor materials, exterior walls and other products with ecological properties through photocatalytic technology, which not only realizes the large-scale application of photocatalytic technology, but also protects human beings. Contribute to the improvement of the space environment that is closely related to life and work. The published patent documents and known technologies of photocatalytic inorganic ecological decorative panels have not been reported in the literature.
