Problems solved by technology

At first, people used porous materials such as sponge and clay to absorb oil, but the results were not satisfactory. This oil-absorbing material has obvious disadvantages: (1) the oil absorption is not large, and the oil absorption ratio is small; (2) the oil-water selectivity is not high, It often absorbs water while absorbing oil; (3) After oil absorption, the oil retention is poor, and it will leak oil again after a little pressurization
(4) The source of raw materials
[0004] However, the current high-resin oil-absorbing materials are often expensive and not suitable for large-scale use

Abstract

The invention discloses a glass-fiber-added composite absorbing material and a preparation method thereof. The composite absorbing material is mainly prepared from polypropylene, trioctyl metabenzene tricarboxylate and butyl acrylate by adding sodium carboxymethyl cellulose, polyoxyethylene laurate, polybenzimidazole imide, 2-hydroxy-6-methyl benzoic acid, diphenyl silanediol, potassium persulfate, diatomite, alkali-free glass fiber, hydroxy aluminum distearate, nano zinc oxide, andalusite powder, potassium salicylate, a surface treating agent and a foaming agent. The preparation method comprises the following steps: grinding, sintering, ultrasonic treatment, polymerization, acid pickling, dry treatment, extrusion, foaming, granulation and the like. The glass-fiber-added composite absorbing material has the advantages of excellent oil absorbing effect for crude oil, excellent mechanical oil holding effect, favorable oil retaining effect and high absorption rate, can satisfy the requirements of industry, and has favorable application prospects.

Description

technical field [0001] The invention relates to the field of novel composite materials, in particular to a composite absorbent material added with glass fibers and a preparation method thereof. Background technique [0002] High oil-absorbing material is a kind of oil-absorbing material that appeared in the 1960s and developed rapidly in the past ten years. At first, due to the need of oil pollution control, researchers became interested in it. With the development of industry, the pollution caused by oily wastewater, liquid waste, and offshore oil spills can no longer be ignored. Failure to solve these problems will cause greater damage to the earth and human beings. Oil-absorbing resin is one of the important ways to help people solve this problem. The development of oil-absorbing materials has experienced a process of evolution from traditional to high-performance. At first, people used porous materials such as sponge and clay to absorb oil, but the results were not sa...
