Abstract

The invention discloses modified diatomite-based multifunctional building board, and belongs to the technical field of building materials. The modified diatomite-based multifunctional building board is prepared by the following steps: calcining diatomite to obtain primary treated diatomite; mixing the primary treated diatomite with an agar liquid, performing nitrogen charging and thermal insulation reaction, so that secondary treated diatomite is obtained; mixing the secondary treated diatomite with a casein solution to obtain tertiary treated diatomite; mixing the tertiary treated diatomite with a ferric chloride solution, and performing vacuum concentration, so that quaternary treated diatomite is obtained; performing ball milling on the quaternary treated diatomite with paraffin wax, soas to obtain modified diatomite; and mixing the modified diatomite, silane coupling agent, sepiolite, modified carbonized coconut shell fiber, phenolic resin, polyvinyl alcohol solution, curing agentand water to obtain a mixed slurry, and then injecting the mixed slurry into a mold, putting the mold into a hot press, and performing hot press molding, so that the modified diatomite-based multifunctional building board is obtained. The modified diatomite-based multifunctional building board has a good bending strength, and has a certain purifying effect on formaldehyde.

Description

technical field [0001] The invention discloses a modified diatomite-based multifunctional building plate, which belongs to the technical field of building materials. Background technique [0002] With the increasing level of modern social economy and technology, the majority of urban and rural residents pay more and more attention to the safety and comfort of the indoor living environment. Dry and wet conditions, formaldehyde pollution, PM2.5, air-conditioning diseases, etc. have long become public concerns. A hot topic, environment-regulating porous materials with strong adsorption media such as diatomaceous earth and activated carbon as functional components have therefore become one of the research hotspots. [0003] Diatomite is a soft rock formed by transporting, depositing and mineralizing under the action of natural factors after the death of extremely abundant single-celled diatoms in ancient times. The properties are also relatively stable, and traditionally mainly...
