Abstract
The invention discloses an oil-resistant environment-friendly fiber-modified nano architectural substrate and a preparation method thereof. The oil-resistant environment-friendly fiber-modified nano architectural substrate is prepared from the following raw materials in parts by weight: 50-60 parts of nitrile-butadiene rubber, 30-40 parts of polyurethane rubber, 10-15 parts of methyl 12-hydroxystearate, 8-12 parts of magnesium methacrylate, 6-10 parts of vinyltris(methylethylketoximino)silane, 20-25 parts of nylon 66 short fiber, 5-10 parts of propylene glycol polyadipate and 10-16 parts of diethylene glycol bis allyl carbonate. The compound of the nitrile-butadiene rubber and polyurethane rubber has excellent oil resistance, favorable wear resistance, favorable aging resistance and favorable air tightness; the methyl 12-hydroxystearate, magnesium methacrylate, vinyltris(methylethylketoximino)silane and other aids constitute the bonding system and perform an important function on the bonding between the rubber and nylon 66 short fibers, thereby enhancing the hardness of the rubber product; and the added propylene glycol polyadipate and diethylene glycol bis allyl carbonate are matched to enhance the oil resistance and the temperature resistance of the rubber. By using p-tosyl semicarbazide, fluorocarbon-base silicone oil and 4,4-oxo-bis benzenesulfonyl hydrazide, the prepared material is in a slight foamed state, so the pore structure becomes finer and thicker. Structurally, fibrous membranes with different diameters and porosity are prepared, and the nano graphene for binding the layers improves the porosity and specific area of the compound adsorption membrane and enhances the efficacy.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to an oil-resistant and environment-friendly fiber modified nano-building base material 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 weathe...
