Problems solved by technology

However, due to the existence of various lightweight fine-pore fillers such as titanium dioxide, medical stone, and fiber, the compatibility with polypropylene is poor, the material is relatively rigid, and the ability to resist deformation and fracture is poor, and the impact toughness needs to be improved. Further improve

Abstract

The invention discloses a high-toughness flame-retardant polypropylene material and a preparation method thereof. The preparation method comprises the following steps of: preparing modified isotacticpolypropylene with good impact toughness, flame retardancy and heat resistance by using isotactic polyethylene fibers, hexahydroxymethylaminotristritrientriene, and temperature-resistant toughening filler, obtaining a compact fiber net with good adhesive force, compatibility, ultraviolet ray resistance and flame retardancy through the melt spinning of the modified isotactic polypropylene, a sisalfiber composite light stabilizer loaded with FeTiO3 / titanium dioxide, and an adhesion promoter, carrying out infiltration and hot pressing on the compact fiber net in an ester-soluble chlorinated polypropylene resin solution, and discharging to obtain the polypropylene material. On the basis of maintaining the good toughness and flame retardance, the dust removal and sterilization efficiency of the obtained polypropylene material is greatly improved; and an automobile lining prepared by the polypropylene material is not easy to crack and wrinkle under the condition of long-term illumination and rain.

Description

technical field [0001] The invention relates to the technical field of polypropylene materials for automobile inner linings, in particular to a high-toughness flame-retardant polypropylene material and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, people's requirements for automobiles are not only the quality, function and beautiful appearance of the automobile itself, but also the requirements for the functional decoration of automobiles are getting higher and higher. The research and development of materials for seemingly inconspicuous automobile interior linings such as automobile roof linings and automobile leaf inner linings has also attracted much attention due to their special functions. Among them, the leaf liner can reduce the impact of road noise from the isolated tires on the cockpit, block the damage to the chassis and fender sheet metal parts caused by muddy water and stones thrown by the rolli...
