Calcium silicate graphene nano-base material for filtering and removing haze molecules and production method thereof

Abstract

The invention discloses a calcium silicate graphene nano-base material for filtering and removing haze molecules. According to the material, the mechanical performance, aging resistance and processing performance can be improved due to combination of ethylene-vinyl acetate copolymer; ammonium polyphosphate has an effect in a condensed phase; a filter fibrous film is prepared from titanium dioxide and degradable polylactide chitosan, has double functions of adsorbing aerosol and volatile organic matters and has the advantages of degradability and environmental friendliness; since positive charges are carried in molecules, the chitosan can be used for adsorbing bacteria carrying negative charges, so that the chitosan has a sterilization function; and structurally, fibrous film layers with different diameters and porosities are prepared, and are combined with nano-graphene among layers, the porosity and specific surface area of a composite adsorbing film are improved, and the effect is reinforced.

Description

technical field [0001] The invention relates to the technical field of building materials, more specifically to a filter composite haze-removing molecular calcium silicate graphene nano-substrate and a production method thereof. Background technique [0002] At present, most bricks are prepared by sintering clay. However, with the increase of clay mining, clay resources are increasingly scarce, which not only increases the mining cost, but also has a serious impact on the ecological environment. Therefore, it is urgent to optimize and improve the existing bricks. There are brick-making methods to change the status quo. [0003] Decomposing zircon sand with sodium hydroxide is the main production process for producing zirconium oxychloride and zirconium dioxide in my country. my country's annual production capacity of zirconium oxychloride reached 150,000 tons in 2007, ranking first in the world. The demand for zirconia as a functional material and structural material is ...

Therefore, it is necessary to maintain frequent ventilation and put adsorption materials in the car, such as activated carbon or a composite product of melt-blown material and large-particle activated carbon, to absorb harmful gases and purify the air in private cars, but such products often have a certain lifespan. It needs to be replaced frequently, and it is generally easy to be forgotten or ignored without marking or reminding, and cannot effectively guarantee the environment in the private car
