Abstract
The invention discloses a preparation method of a novel reinforced flame-retardant bamboo fiber / polypropylene composite material. A non-woven fabric paving technology is adopted to prepare the bamboo fiber / polypropylene composite material, halloysite nanotubes (HNTs), phytic acid (TA) and manganese chloride tetrahydrate MnCl2. 4H2O are adopted as raw materials, ionic reaction is adopted to enhance and modify the bamboo fiber / polypropylene composite material, and finally, a hot press molding technology is adopted to prepare the flame-retardant bamboo fiber / polypropylene composite material. The bio-based material phytic acid is used as a raw material to prepare the flame-retardant bamboo fiber / polypropylene composite material, the flame-retardant bamboo fiber / polypropylene composite material has excellent flame retardance while maintaining good mechanical properties, the limit oxygen index (LOI) is improved by 12.5%, the total smoke release amount (TSP) is reduced by 32%, and the flame-retardant bamboo fiber / polypropylene composite material has wide application prospects in the fields of automotive trim, building decoration and the like.
