Abstract

The invention discloses a foamed polypropylene-high molecular absorbent composite anti-aging filtering material. The foamed polypropylene-high molecular absorbent composite anti-aging filtering material is prepared from, by weight, 95 to 98 parts of high melt strength polypropylene, 2 to 3 parts of liquid paraffin, 5 to 7 parts of azodicarbonamide, 2 to 3 parts of low density polyethylene, 4 to 5.5 parts of nano-montmorillonite, 1 to 2 parts of anti-oxidant 1010, an appropriate amount of deionized water, 4 to 5 parts of methyl cellulose, 13 to 15 parts of butyl acrylate, 7.5 to 9 parts of dodecyl methacrylate, 0.08 to 0.1 part of N,N-methylene bisacrylamide, 0.5 to 0.6 part of azodiisobutyronitrile, 11 to 12.5 parts of ethyl acetate, and 2 to 3 parts of di-cotyl phosphoric acid. The foamed polypropylene-high molecular absorbent composite anti-aging filtering material is capable of absorbing almost all kinds of liquid organic chemicals including fuel such as gasoline, diesel oil, aircraft fuel, and crude oil, aromatic solvents such as benzene and xylene, and chlorinated solvents and polar compounds such as perchloroethylene and methyl ethyl ketone.

Description

technical field [0001] The invention relates to the field of materials, in particular to a composite anti-aging filter material of foamed polypropylene and polymer absorbent and a preparation method thereof. Background technique [0002] At present, the problem of environmental pollution in global waters is becoming more and more serious. Among them, the pollution of oily substances and their sewage, waste liquid, and water resources such as rivers and oceans caused by various accidents such as leakage of oil tankers or storage tanks is becoming more and more serious. Effective containment and solutions are urgently needed. [0003] Oil-absorbing materials can be mainly divided into three categories, namely inorganic oil-absorbing materials, organic synthetic oil-absorbing materials and organic natural oil-absorbing materials. Expanded polypropylene foam is a high-crystalline composite material with excellent performance. Compared with other thermoplastic polyolefins, polypr...
