Abstract

The invention provides a rare earth silicone oil modified jute fiber / polypropylene or polypropylene alloy compound material and a preparation method thereof. The material is compounded from modified jute fiber processed by using a rare earth silicone oil modification solution and polypropylene or a polypropylene alloy. The modified biomass jute fiber is a modified jute fiber with a rare earth lanthanum ion-polysiloxane functional structure which is formed under the joint action of rare earth ions and silicone oil molecules. The rare earth silicone oil modified jute fiber has the advantages ofno impurity phase on the surface, greatly reduced surface fine structure defects and changed surface characteristics such as polarity, hydrophily and the like. In the preparation method of the compound material, after being modified with the rare earth silicone oil, natural jute fiber is subjected to extrusion, granulation and injection molding together with the polypropylene or polypropylene alloy. The compound material has the advantages of excellent mechanical property, environmentally friendliness and no toxicity or harm, and can be widely used in the field of transportation means such asautomobiles, light railways, express railways and the like, and the industries such as building, office furniture and the like.

Description

technical field [0001] The invention belongs to the subject field of new materials, in particular to a rare earth silicone oil modified hemp fiber / polypropylene and its alloy new material and its preparation method. technical background: [0002] With the increasing shortage of international energy, rising energy prices and increasing pressure on environmental protection, governments of various countries are paying more and more attention to the research and application development of energy saving, environmental protection and recyclable materials. The natural bio-hemp fiber / polymer composite is a new material that meets the requirements of energy saving, environmental protection and recyclability. Natural bio-hemp fibers include low-cost biomass materials such as ramie, flax, sisal, and kenaf. Compared with the composite materials formed by E-glass fiber, artificial carbon fiber and polymer, natural hemp fiber not only has advantages in environmental friendliness and recy...
