Recyclable oil absorbing composite material and preparation method therefor

Abstract

The present invention discloses a recyclable oil absorbing composite material and a preparation method therefor. The ecyclable oil absorbing composite material is characterized by being prepared by using the following raw materials in parts by weight: 3-5 parts of sodium bentonite, 0.3-0.5 parts of cetyl trimethyl ammonium bromide (CTAB), 4-6 parts of methacrylate, 3-5 parts of styrene, 0.1-0.5 parts of 1,6-hexanediol diacrylate, 3-4 parts of ethyl acetate, 1-3 parts of polyvinyl alcohol, 0.8-1.2 parts of organophosphorus ester, 0.01-0.05 parts of potassium persulfate, 0.5-1 parts of sodium bicarbonate, 2-5 parts of polyethylene wax, 2-3 parts of stearic acid, 1-2 parts of calcium sulfate, 80-95 parts of polypropylene, 0.1-0.3 parts of antioxidant 1010, 10-15 pats of azodicarbonamide, 0.5-1 parts of silane coupling agent KH550, 2-3 parts of peat, 0.5-1 parts of lanthanum nitrate, 1-2 parts of silicone acrylic emulsion and an appropriate amount of water. The recyclable oil absorption composite material provided by the present invention has characteristics of high oil absorption multiple, fast oil absorption speed, good oil-water selectivity, high oil retention, reusability and the like, and can be widely used in treating pollution of oil on water surface and recycling oil in sewage.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a recyclable oil-absorbing composite material and a preparation method thereof. Background technique [0002] With the development of industry and the improvement of people's living standards, the environmental pollution caused by the discharge of oily waste water and waste gas and the increase in leakage accidents of oil tankers and oil tanks has become increasingly serious, which has already constituted a threat to the ocean and people's lives. As a new type of functional polymer material, super oil-absorbing resin material is different from ordinary oil-absorbing materials in the past. It can not only achieve the purpose of high-efficiency oil absorption, but also has the characteristics of various types of oil absorption, fast oil absorption rate, high oil absorption ratio, oil absorption but not water absorption, etc. Not only can it replace traditional oil-absorbi...

Problems solved by technology

However, as an adsorption material, this material has some disadvantages, namely, oil absorption and water absorption, and leakage after absorption after extrusion. Due to the porous structure, the specific surface area is large, and the volatility of the absorbed highly volatile liquid cannot be suppressed, which is harmful to toxic and explosive chemicals. Product processing effect is not ideal
