A kind of porous oxidized inorganic ecological decorative board and production method thereof

Abstract

The invention discloses a pore-forming oxidative inorganic ecological decorative board and a production method thereof. The pore-forming oxidative inorganic ecological decorative board is prepared from, by weight, 100 parts of inorganic gelling powder, 0-22.0 parts of porous powder, 18.5-73.0 parts of liquid-phase medium, 0.05-5.5 parts of pore-forming compound catalytic oxidant, 1.5-20 parts of reinforced fibers and 1.3-4.5 parts of nanometer titania coating materials by stirring, forming, curing, drying and a veneer treatment technology. The pore-forming oxidative inorganic ecological decorative board has the advantages that a catalyst and the oxidant are supported on micropores inside a hydrated condensation matrix of the inorganic gelling material firmly simultaneously, microporous distribution and centralized distribution are enriched, and secondary intensification is achieved with the aid of a nanometer titania coating, so that the inorganic ecological decorative board is endowed with excellent purification performance to efficiently decompose harmful gas continuously and is capable of regulating indoor temperature and humidity effectively, resisting bacteria and preventing mildewing; the problems of contradiction in choosing physical performance and ecological performance of inorganic decorative boards alternatively, proneness to shedding and attenuation of the supported catalyst or oxidant and capability of causing blockage of surface micropores through conventional surface treatment are solved.

Description

technical field [0001] The invention relates to a porogenic oxidation inorganic ecological decorative board and a production method thereof, belonging to the technical field of green ecological environment building materials; through the porogenic technology, the catalyst and the oxidant are firmly hydrated and condensed into a matrix by the inorganic gelling material, and are firmly loaded on the inorganic gelling material. The material hydrates and coagulates the internal micropores of the matrix, and is reinforced by the nano-titanium dioxide coating layer to give the inorganic decorative board excellent purification performance, continuously and efficiently decompose harmful gases, and effectively adjust indoor temperature and humidity, antibacterial and anti-mildew and other ecological properties. Background technique [0002] Calcium silicate board, high-strength crystal decorative gypsum board (high crystal board), precast glass fiber reinforced gypsum composite materi...

Problems solved by technology

Compared with algae-calcium ecological composite materials and decorative panels, the technology needs to expand in the stability of raw materials and ecological purification technology to avoid the impact of fluctuations in raw materials; compared with the existing photocatalytic inorganic ecological decorative panels, it is necessary to avoid the use of expensive light Catalyst and a single photocatalytic technology, in order to obtain a faster, thorough purification rate and high cost performance, it is necessary to solve the problem of reducing ecology due to partial clogging or sealing of the micropores of the substrate due to the decoration treatment; while the oxidative air purification material technology is applied to Inorganic ecological decorative panels have not been reported yet, and it is obviously not suitable for large-scale continuous operation to load oxidants on inorganic ecological decorative panels by impregnation.
