Compound oil-absorbing material with flame retardant property and preparation method thereof

Abstract

The invention discloses a compound oil-absorbing material with flame retardant property and a preparation method thereof. The compound oil-absorbing material is prepared by the following steps of: adopting polytetrafluoroethylene, dimethylaminoethyl acrylate, ethylhexyl palmitate, o-hydroxybenzoic acid phenyl ester and acetyl tributyl citrate as main components, adding polyvinylpyrrolidone, epoxidized sunflower oil, diphenyl silanediol, siliceous lime, nano microcrystalline ceramic powder, titanium dioxide, ramie fiber, L-glutamic acid diethyl ester hydrochloride, polyphenyl quinoxaline, hydroxygenkwanin, surface active agent and foaming agent, and adopting processes of grinding, sintering, ultrasonic treatment, polymerization, acid leaching, dry-process treatment, extrusion, foaming and granulation and the like. The compound oil-absorbing material disclosed by the invention is excellent in flame-retardant effect, has excellent oil-absorbing effect and mechanical oil-holding effect for crude oil, has no toxicity, can meet the industrial requirements and has better application prospect.

Description

technical field

[0001] The invention relates to the field of novel composite materials, in particular to a composite oil-absorbing material with flame-retardant properties and a preparation method thereof. Background technique

[0002] Due to the development of industry and the needs of people's life and production, the consumption of petroleum resources is increasing day by day, resulting in the continuous expansion of petrochemical enterprises, and the resulting oily sewage has more complex and diverse water quality, and the pollution problems caused by it are becoming more and more serious. Oil leakage will pollute the coastline, endanger marine life, and also destroy the seaside scenery, affect the aesthetic value, and bring huge losses to the economy. The methods commonly used to deal with oil slicks on the water surface include physical, chemical and biological techniques. The main measure to deal with oil spills at sea is to use oil-absorbing substances to mechanicall...
