Abstract

The invention discloses an expansion-proof fiber modified nano-adsorption building base material and a preparation method for the same. The expansion-proof fiber modified nano-adsorption building base material is prepared from the following raw materials in parts by weight: 50 to 70 parts of activated carbon, 12 to 20 parts of montmorillonite, 5 to 12 parts of nano-titania, 1 to 10 parts of gamma-aminopropyltriethoxysilane, 6 to 12 parts of hydroxy propyl methyl cellulose, 4 to 8 parts of nickel nitrate and the like. According to the expansion-proof fiber modified nano-adsorption building base material and the preparation method for the same, added nitrile rubber modified phenol-formaldehyde resin and the raw materials are mixed, and are cured when being heated, and the molten resin is rapidly turned from a linear structure to an unmolten three-dimensional structure under the action of methylene decomposed from hexamethylenetetramine, so that mechanical performance is improved, and the performance of resistance to high temperature and low expansion are achieved; chitosan molecules are positively charged to adsorb negatively charged bacteria, so that a bactericidal function is realized; structurally, fiber film layers with different diameters and porosities are prepared, and nano graphene between the layers is combined, so that the porosity and the specific surface area of a composite adsorption film are improved, and effects are enhanced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an expansion-resistant fiber modified nano-adsorption building substrate and a preparation method thereof. Background technique [0002] Smog is a mixture of fog and haze. When the humidity is high in the morning and evening, the composition of fog is more. When the humidity is low during the day, haze dominates, and the relative humidity is between 80% and 90%. Among them, fog is a natural weather phenomenon, and the water vapor in the air is dense. Although dust is used as condensation nuclei, it is generally non-toxic and harmless; the core substance of haze is smoke, dust and other substances suspended in the air. The relative humidity of the air is lower than 80%, and the color is yellow. The gas can directly enter and adhere to the lower respiratory tract and lung lobes of the human body, which is harmful to human health. The formation of smog weather is mainly ...
