Problems solved by technology

The result is not ideal. This oil-absorbing material has obvious disadvantages: the oil absorption ratio is small, and the oil will leak again after a little pressurization after oil absorption. These shortcomings limit their application to a certain extent.
In the second stage, hydrophobic polymer materials such as polypropylene and polyethylene are used to make mesh felt with a certain degree of po

Abstract

The invention relates to a high oil absorption composite material containing cellulose waste filler and a preparation method thereof. The composite material takes acrylic ester multipolymer high oil absorption resin as base material, in which the cellulose waste in the shape of island is uniformly dispersed in the base material. The preparation includes the following steps of: the preparation of the base material, namely the acrylic ester multipolymer high oil absorption resin; the preparation of the cellulose waste filler; the blending of the high oil absorption resin and the cellulose waste filler to prepare the high oil absorption composite material. Compared with the prior art, the composite material has the following advantages of excellent oil absorption performance, the availability to absorb a plurality of oils, high oil absorption percentage and good fat-binding performance. The key technology of the invention lies in the acrylic ester multipolymer oil absorption resin, which has wide raw material source, takes water accounting for 60-80 percent as dispersing medium, and the technology is simple and easily controllable. The filler is natural cellulose waste with the particle diameter of 0.25-0.035mm. The waste can be bagasse, corn cob, peanut shells and sawdust powder, and has wide source, belongs to resource recycling area, conforms to the national policy of sustainable development and is simple, safe and environment-friendly in preparation process.

Description

Technical field: [0001] The invention relates to an oil-absorbing composite material, in particular to a high oil-absorbing composite material containing cellulose waste filler and a preparation method thereof. Background technique: [0002] High Oil-Absorbable Resin (HOAR for short) is a new type of functional polymer material that can replace traditional oil-absorbing materials. It plays an important role in removing oil pollution and improving the living environment of human beings. [0003] At present, oil-absorbing materials are divided into three stages from the development of materials: in the first stage, porous materials such as cotton, sponge and clay are used to absorb oil. The oil-absorbing principle is based on capillary absorption, which is a kind of physical adsorption. The result is not ideal. This oil-absorbing material has obvious disadvantages: the oil absorption rate is small, and the oil will leak again after a little pressurization after absorbing the o...
