Foamed polypropylene and polymer absorbent composite material with high flame-retardant effect and preparation method thereof

Abstract

The invention discloses a foamed polypropylene and polymer absorbent composite material with a high flame-retardant effect. The foamed polypropylene and polymer absorbent composite material is characterized by being prepared from, by weight, 95-98 parts of high-melt-strength polypropylene, two to three parts of low-density polyethylene, two to three parts of diisopropyl azodicarboxylate, 0.6-0.8 part of polydimethylsiloxane, three to four parts of antimonous oxide, one to two parts of red phosphorus, a proper amount of deionized water, four to five parts of methylcellulose, 13-15 parts of butyl acrylate, 7.5-nine parts of dodecyl methacrylate, 0.08-0.1 part of N,N,-methylene bisacrylamide, 0.5-0.6 part of azodiisobutyronitrile, 11-12.5 parts of ethyl acetate and two to three parts of bis phosphate. The foamed polypropylene and polymer absorbent composite material is excellent in flame retardant property, spontaneous combustion, caused by oil absorption, of products is avoided, and potential safety hazards are reduced. The foamed polypropylene and polymer absorbent composite material is widely applied to petroleum leakage, water pollution control, oil-water separation, dangerous chemical protection, emergency treatment and other fields.

Description

technical field [0001] The invention relates to the field of materials, in particular to a foamed polypropylene and polymer absorbent composite material with flame-retardant effect and a preparation method thereof. Background technique [0002] Petroleum is known as "black gold" and "economic blood", and is widely used in various fields of the national economy. With the rapid development of my country's economy and the increase in energy demand, its application scope is still expanding, and its consumption is also increasing day by day. During the extraction, processing, transportation, refining and use of crude oil, due to the limitation of technological level and treatment technology, a large amount of waste water and waste residue containing oily substances will inevitably be discharged into the water body, which will affect the marine ecological environment and fresh water. The ecological environment has caused great damage. Oil spills and oil stains in water not only ...

Problems solved by technology

However, as an adsorption material, this material has some disadvantages, such as low gravity oil retention rate, leakage after being squeezed after absorption, and large specific surface area due to porous structure, which cannot suppress the volatility of the absorbed highly volatile liquid, which is harmful to toxic Unsatisfactory handling of explosive chemicals, etc.
