Abstract
The invention discloses an expansion-resistant nano building material for preventing smog and a preparation method of the expansion-resistant nano building material. The expansion-resistant nano building material is prepared from the following raw materials in parts by weight: 50 to 70 parts of active carbon, 12 to 20 parts of montmorillonite, 5 to 12 parts of nano titanium dioxide, 3 to 7 parts of silicon dioxide, 1 to 10 parts of gamma-aminopropyltriethoxysilane, 6 to 12 parts of hydroxypropyl methyl cellulose and 5 to 10 parts of oligomerization 3-aminopropyltriethoxysilane. The added nitrile rubber modified phenolic resin is mixed with raw materials to be cured by heating, and the molten resin is converted rapidly from a linear structure to a non-molten mass structure under the effect of methylene separated from methenamine; and the mechanical performance is improved, so that the expansion-resistant nano building material has high temperature resistance and low expansion performance. The expansion-resistant nano building material has the characteristics of high adsorption capacity, relatively good thixotropy, heat stability, plasticity, viscosity, high dry pressure and the like. By adding reinforcing agents such as coal gangue, conductive mica powder and nano conductive graphite powder, the heat aging resistance and crack resistance can be improved, so that the casting efficiency can be improved, and the casting cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to an expansion-resistant nanometer building material for preventing and treating smog 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...
