Abstract

The invention belongs to the field of diatom boards, and especially relates to a graphene aldehyde removing diatom board and a preparation method thereof. The diatom board comprises following components: diatomite, a calcium material, a mineral material, an aqueous fiber, a thickening fiber, a graphene modified aldehyde removing agent, and water. The preparation method comprises following steps: mixing and stirring all components together, extruding the mixture in demoulding cloth, allowing the mixture to stand still, drying, and baking to obtain the graphene aldehyde removing diatom board. Diatomite and the calcium material are taken as the basic materials, at the same time, the graphene modified aldehyde removing agent is added so that harmful gas that is absorbed by the diatomite can berapidly decomposed into carbon dioxide and water, the surface compactness of the diatom board is greatly improved, the toughness and strength of the diatom board are enhanced; the added fibers can prevent the cracking and deformation of the diatom board, when the diatom board shrinks in a dry environment, the strength of the diatom board is further strengthened, and thus the service life of the diatom board is prolonged.

Description

technical field

[0001] The invention belongs to the field of diatom boards, in particular to a graphene aldehyde-removing diatom board and a preparation method thereof. Background technique

[0002] Diatomaceous earth is a natural inorganic mineral, the main component is silicon dioxide, and its non-toxic and harmless microporous structure enables it to have functions such as heat preservation, heat insulation, adsorption, and humidity control. At the same time, diatomite can also absorb volatile organic compounds and odors, such as formaldehyde and benzene, so diatomite is widely used in the field of functional architectural decoration. However, diatomite cannot further decompose the adsorbed harmful substances, and the harmful gases will volatilize again in an environment with a suitable temperature, causing secondary pollution. As a new type of interior decoration material, diatom board is directly in contact with the home environment, accompanied by the main life, workp...
