Embodiment

[0023] Such as figure 1 Shown, a kind of biodegradable woven bag is made of the following components by weight: 8 parts of starch-based PLA (polylactic acid), bio-based PBAT (polybutylene adipate / butylene terephthalate, Namely a copolymer of butylene adipate and butylene terephthalate) 62 parts, 1.5 parts of ACR, 25 parts of calcium carbonate powder, 2 parts of glycerin and 1.5 parts of glycerin fatty acid.

[0024] The ACR is a copolymer of methyl methacrylate and acrylate. The density of the ACR is 1.1 g / cm 3 .

[0025] The particle size of the calcium carbonate powder is 3000 mesh.

[0026] The preparation method of described woven bag, comprises the steps:

[0027] S1. Add starch-based PLA, bio-based PBAT, ACR, calcium carbonate powder, glycerin and glycerol fatty acid into a high-speed mixer in parts by weight, and mix for 3 minutes at a speed of 200r / min;

[0028] S2. After releasing the uniformly mixed material, it is added to a twin-screw extruder, extruded, drawn...

Abstract

The invention discloses a biodegradable woven bag and a preparation method thereof. The woven bag is prepared from the following components in parts by weight: 3-10 parts of starch-based PLA, 60-65 parts of bio-based PBAT, 1-2 parts of ACR, 30-35 parts of calcium carbonate powder, 2-3 parts of glycerin and 1-2 parts of glycerin fatty acid. Compared with the traditional woven bag, the woven bag disclosed by the invention has excellent mechanical property, air permeability, water permeability and puncture resistance, and can be completely biodegraded to realize zero pollution.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a biodegradable woven bag and a preparation method thereof. Background technique [0002] Woven bags are widely used in agricultural product packaging, logistics express transportation packaging, etc. Common woven bags are made of petroleum-based plastic PE, PP, PVC and other polyethylene materials. Environmental oxidation such as high temperature and high temperature will corrode and weather into fragments, and then become plastic particles that penetrate into the soil or water, seriously polluting the environment. Contents of the invention [0003] In order to solve the above problems, the present invention provides a biodegradable woven bag and a preparation method thereof. [0004] The present invention adopts following technical scheme: [0005] A biodegradable woven bag made of the following components by weight: 3-10 parts of starch-based PLA, 60-65 parts of ...
