preparation example Construction

[0031]The invention provides a method for preparing a flame-retardant thermoplastic starch-based biomass composite material. According to the method of the invention, firstly, (A1) 100 parts by weight of starch, (A2) 5-75 parts by weight of plasticizer, and ( A3) 5-30 parts by weight of organophosphorus-based flame retardants are mixed and subjected to a kneading and plasticizing process at 60-100° C., preferably 70-90° C., to form a flame-retardant thermoplastic starch material (A).

[0032] Next, mix (A) 5-40 parts by weight of the above-mentioned flame-retardant thermoplastic starch material, (B) 60-90 parts by weight of thermoplastic polymer, and (C) 3-10 parts by weight of toughening agent at 170-260 °C, preferably at 190-240 °C to perform a kneading process to form a flame-retardant thermoplastic starch-based biocomposite.

[0033] The flame-retardant thermoplastic starch-based biomass composite material of the present invention includes: (A) 5-40 parts by weight of flam...

Embodiment 1~17

[0040] The preparation methods of the flame-retardant thermoplastic starch-based biomass composites of Examples 1-17 are as follows, and the types and detailed addition ratios of each material component are shown in Table 2 and Table 3.

[0041] 100 parts by weight of starch, 30-70 parts by weight of water, 5-30 parts by weight of glycerin, and 5-30 parts by weight of flame retardants, including organic phosphorus flame retardants (Chemguard-1045, ORGANIC PHOSPHONATE, constant Bridge Industry Co., Ltd., Chembridge International Corp.), triphenyl phosphate (triphenyl phosphate, TPP), phosphate ester flame retardant (Resorcinol bis(dixylenyl phosphate), PX- 200), or the combination of the above, mixed according to the ratio shown in Table 2 and Table 3;

Abstract

In one embodiment, A flame-retardant thermoplastic starch material, including (A1) 100 parts by weight of starch; (A2) 5 to 75 parts by weight of plasticizer; and (A3) 5 to 30 parts by weight of organic phosphonate flame-retardant, wherein the organic phosphonate flame-retardant has the following formula (I): wherein X is a trivalent aliphatic hydrocarbon radical containing 3 to 12 carbon atoms; R1 and R2 are independently C1 to C8 alkyl; and n is 0 or 1.

Description

technical field [0001] The invention relates to a flame-retardant thermoplastic starch material (Flame-retardant thermo plastic starch material), its bio-composite and a method for preparing the bio-composite. Background technique [0002] Starch is the main form of energy stored in plants and is found in cereals, legumes and tubers. It is cheap and one of the most abundant natural materials in the earth. It has been widely used in different industrial applications such as food, paper making, textile and adhesives. Native starch is partially crystallized micron-sized particles. The particles are formed by the huge hydrogen bond force between starch molecules to form extended network micelles to form a huge aggregation, making it difficult to melt process, so it cannot be used like ordinary plastic plastic materials. thermoplastic processing. In the past, starch was often used as a plastic filler (Filler), which was added to general plastics to reduce costs and increase the...
