Nano-clay added foaming polypropylene and high-molecular absorbent composite material and preparation method thereof

Abstract

The invention discloses a nano-clay added foaming polypropylene and high-molecular absorbent composite material. The nano-clay added foaming polypropylene and high-molecular absorbent composite material is characterized by being prepared by, by weight, 95-98 parts of high-melt-strength polypropylene, 2-3 parts of low-density polyethylene, 5-7 parts of nano clay, 1-2 parts of polyvinyl akohol, 2-3 parts of calcium carbonate, 4-6 parts of ammonium bicarbonate, 0.1-0.2 part of cetyltrimethylammonium chloride, an appropriate amount of deionized water, 4-5 parts of methylcellulose, 13-15 parts of butyl acrylate, 7.5-9 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 2-3 parts of di-cotyl phosphoric acid. The composite foaming material is relatively compact in appearance, small in particles and good in lustrousness, meets the environmental protection requirement, can be prepared by adopting a simple injection molding process, the preparation process of a micro-foaming material is simplified, and comprehensive performance is excellent.

Description

technical field [0001] The invention relates to the field of materials, in particular to a composite material of foamed polypropylene and polymer absorbent added with nano-clay 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 redu...

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.
