Problems solved by technology

Inorganic materials such as activated carbon, expanded graphite, peat, silica, organically modified clay, etc., have been seldom used because of their low oil absorption rate and difficulty in recycling after oil absorption; organic synthetic materials include polypropylene, polyurethane foam, acrylate They have good lipophilicity and oil absorption efficiency, but their expensive cost and refractory property limit their application; natural polymer materials, because of their high oil absorption rate, have a wide range of sources, low prices, And biodegradable, relatively safe has become the focus of research
[0003] Because natural fibers are generally short and thin, and the strength is weak, the oil-absorbing materials prepared by natural fibers have poor mechanical properties. In the prior art, additives are often used to improve the fiber strength of oil-absorbing materials, but the preparation method is usually complicated. , and the degree of coupling between additives and fibers is limited, which greatly limits the improvement of the strength of oil-absorbing materials prepared from natural fibers

Abstract

The invention relates to a method for preparing a high-efficiency oil absorption material by utilizing bambusa emeiensis. The method comprises the following steps: cutting fresh bambusa emeiensis, softening, and splitting; placing split fiber bundle shaped bamboo chips into a pressure tank, and reacting with a reaction solution at a temperature of 150-180 DEG C for 20-30 minutes so as to obtain bambusa emeiensis fibers; and ball-milling the bambusa emeiensis fibers into bambusa emeiensis fiber powder, reacting the bambusa emeiensis fiber powder with ammonium persulfate, 1,4-butylene glycol diacrylate, triethanolamine and dodecyl methacrylate reaction liquid at a constant temperature of 70-80 DEG C for 2-3 hours, washing and drying the obtained product, thereby obtaining the high-efficiencyoil absorption material. The method disclosed by the invention is simple and low in cost, and the prepared oil absorption material has the advantages of being high in mechanical strength, high in oilabsorption rate and biodegradable.

Description

technical field [0001] The invention relates to the technical field of oil-absorbing materials, in particular to a method for preparing high-efficiency oil-absorbing materials by using bamboo. Background technique [0002] In recent years, in the process of oil extraction, refining, transportation, transfer and use of oil products, crude oil and refined oil leakage incidents have occurred frequently, and the pollution to the water environment has become more and more serious. The development of high-efficiency oil-absorbing materials has always been a concern of people. hotspot. Oil-absorbing materials can generally be divided into inorganic materials, organic synthetic materials and natural polymer materials. Inorganic materials such as activated carbon, expanded graphite, peat, silica, organically modified clay, etc., have been seldom used because of their low oil absorption rate and difficulty in recycling after oil absorption; organic synthetic materials include polypro...
