Abstract

The invention provides a flame-retardant thermoplastic starch material, comprising: (A1) 100 parts by weight of starch; (A2) 5-75 parts by weight of a plasticizer; and (A3) 5-30 parts by weight of an organic phosphorus-based flame retardant agent, wherein the above organophosphorus flame retardant has the structure shown in formula I, where X is a trivalent aliphatic hydrocarbon group with 3 to 12 carbons, and R1 and R2 are independent C1~C8 alkyl groups ;n is 0 or 1. The invention also provides a flame-retardant thermoplastic starch-based biomass composite material and a preparation method thereof.

Description

Technical field [0001] The present invention relates to a flame-retardant thermo plasticstarch material (Flame-retardant thermo plasticstarch material), its bio-composite and a preparation method of the above-mentioned bio-composite. Background technique [0002] Starch is the main form of energy storage in plants and is found in cereals, beans and tubers. It is one of the natural materials that are cheap and rich in the earth's content, and has been widely used in different industrial applications such as food, papermaking, textiles and adhesives. Native starch is a partially crystalline micron-sized granule. This granule is formed by the huge hydrogen bonding force between the starch molecules to form an expanded network of micelles to form a huge aggregation, making it difficult to melt processing, so it cannot be used as a general plastic material. Thermoplastic processing. In the past, starch was often used as a filler (Filler) for plastics and used to add to general plast...
