Kenaf core/resin composite oil-absorption material and preparation method thereof

Abstract

The invention relates to a kenaf core / resin composite oil-absorption material and a preparation method thereof. The preparation method is characterized in that kenaf core waste in a textile industry is taken as a raw material to carry out graft copolymerization on oil-absorption resin and cellulose on the surfaces of kenaf core particles, so as to obtain a degradable kenaf core / resin composite high-oil-absorption resin. Compared with traditional inorganic oil-absorption materials and resin oil-absorption materials, the kenaf core / resin composite oil-absorption material and the preparation method have the advantages that the production cost can be substantially lowered, the waste of the textile industry is effectively utilized, and by utilizing a unique porous structure of a kenaf core, the oil absorption and keeping properties of the oil-absorption material are greatly improved; besides, after the kenaf core is subjected to graft copolymerization with the resin, the water absorbing capacity of the kenaf core is reduced, and the ratio of the oil absorbing capacity to the water absorbing capacity of the kenaf core is increased; the kenaf core simultaneously has the biodegradability of a straw and high water absorbing performance of the resin.

Description

technical field [0001] The invention relates to the technical field of oil-absorbing materials, in particular to a kenaf stalk / resin composite oil-absorbing material and a preparation method thereof. Background technique [0002] In recent years, the problem of water environmental pollution has become more and more serious, especially the oil spill incident and the treatment of oily wastewater have become the key issues in environmental protection work, and oil pollutants have become one of the main pollutants in water bodies. [0003] Adsorption method is a relatively common method for treating oily wastewater. The oil-absorbing material used in this method is a functional material used for waste oil recovery and treatment. It is widely used in oil leakage from factory machines, oil in factory wastewater, and food waste. Oil, offshore and onshore crude oil spill treatment, etc. Commonly used oil-absorbing materials mainly include inorganic type and organic type. Inorganic...
