Ageing-resistant nano modified environmental-friendly master batch plastic and preparation method thereof

Abstract

The invention discloses an ageing-resistant nano modified environmental-friendly master batch plastic and a preparation method thereof. The plastic comprises the following raw materials in parts by weight: 12-25 parts of butylene terephthalate, 10-15 parts of a tetrafluoroethylene-hexafluoropropylene copolymer, 10-20 parts of an acrylonitrile styrene acrylate copolymer, 60-80 parts of polycarbonate, 10-15 parts of nano barium carbonate, 20-25 parts of aramid short fibers and 2-10 parts of silicon carbide wafers. As molecules of chitosan have positive charges, the plastic can adsorb bacteria with negative charges, so that the plastic has a sterilizing function. Fiber membrane layers of different diameters and porosities are prepared structurally, the porosity and specific surface area of a compound adsorption membrane are improved by combining nanographene among layers, and the function is enhanced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an aging-resistant nano-modified environmentally friendly color masterbatch 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 main...

Problems solved by technology

The formation of smog weather is mainly caused by man-made environmental pollution, coupled with natural conditions such as low temperature and wind, which make it difficult for pollutants to spread
