Embodiment 1

[0029] Bamboo powder polybutylene succinate starch biodegradable plastics are prepared as follows:

[0030] Step 1: Put 20 parts of starch, 0.4 parts of biological enzyme, and 4.5 parts of titanium dioxide into a high-speed grinder and mix evenly to obtain a mixed material A;

[0031] Step 2: put 15 parts of bamboo powder into a high-speed grinder and grind it to 3000-4000 meshes, transfer the ground bamboo powder directly to a kneading mixer, add the mixed material A and 0.3 parts of natural oil successively for mixing ;

[0032] Step 3: Add 37.5 parts of polybutylene succinate, 17 parts of 6000-mesh talc powder, and 0.3 parts of chitin to the kneading mixer in step 2 to continue mixing, control the mixing temperature to 130 °C, and mix The mixing time is 2 to 4 hours. The raw materials are further refined and dispersed in the mixing chamber through rotor friction and shearing to obtain the mixed material B;

[0033] Step 4: put the mixed material B into a bioreactor throug...

Abstract

The invention provides bamboo powder/poly(butylene succinate)/starch biodegradable plastic and a preparation method thereof. The bamboo powder/poly(butylene succinate)/starch biodegradable plastic provided by the invention comprises the following components in parts by weight: 15-25 parts of bamboo powder, 30-45 parts of poly(butylene succinate), 15-25 parts of starch, 12-20 parts of talcum powderand the like. The bamboo powder/poly(butylene succinate)/starch biodegradable plastic prepared by the invention is wide in raw material source and safe, does not contain any chemical additive with toxic and side effects, can be used for producing disposable tableware products such as knives, forks, spoons, cup covers, straws, bowls and lunch boxes, can be completely degraded after being used, andis short in degradation period.

Description

technical field [0001] The invention relates to the technical field of biodegradable new materials, in particular to a bamboo powder polybutylene succinate starch biodegradable plastic and a preparation method thereof. Background technique [0002] Polylactic acid (PLA), as a degradable and renewable polymer, has excellent biocompatibility and mechanical properties of high strength and high modulus. However, the high cost of polylactic acid has no advantages compared with ordinary petroleum-based plastics, which limits its wide-scale promotion. Even if other biomass materials such as bamboo powder and wood powder are added to polylactic acid biodegradable plastics widely used at present, and polylactic acid is compounded to reduce raw material costs, the content of polylactic acid is still relatively high, which is necessary for controlling raw material costs. Therefore, the development of a biodegradable composite material with energy saving, environmental protection, high...
