Problems solved by technology

At present, many researchers are trying to apply some bio-based materials derived from organisms or their deep-processed products to the preparation of fully biodegradable materials. For example, they combine some directly processable bio-based resins (such as PLA, PHBV, PBS) with Some biomass materials (such as starch, cellulose, straw, etc.) that need to be dispersed and plasticized are mixed to prepare fully bio-based and fully biodegradable materials. However, most of the materials obtained by this method are injection molding materials, which cannot be used as films Material modification
At the same time, because the intermolecular forces between biomass materials and bio-based resins are quite different, it is difficult to obtain products with superior performance by blending the two

Abstract

The invention relates to a bio-based environment-friendly degradable material, a film prepared from the bio-based environment-friendly degradable material and a preparation method of the film. The material is prepared from the following raw materials: starch, polylactic acid, glycidyl methacrylate, magnesium stearate, epoxy soybean oil, glycerol, diphenylmethane diisocyanate, 2-phenyl-2-oxazoline,sodium dodecyl benzene sulfonate, 1,3-dimethyl-6-aminouracil, N,N'-bis(2,6-diisopropylphenyl)carbodiimide, dioctadecyl pentaerythritol diphosphite, cerium stearate, phenyl bis(2,4,6-trimethylbenzoyl)phosphine oxide and potassium chloride. The material can be applied to preparation of the film. The prepared film has high mechanical properties, and can be degraded rapidly in a short time, thus eliminating the 'white pollution' truly.

Description

technical field [0001] The invention relates to a bio-based environment-friendly degradable material, a film prepared therefrom and a preparation method of the film. Background technique [0002] The wide application of plastics has brought a lot of convenience to people's lives, and it has also formed a recognized white pollution. Since the 1960s, many researchers have devoted themselves to accelerating the degradation of plastics or seeking alternatives to traditional plastics, and proposed the concept of degradable plastics in the 1970s. At present, many researchers are trying to apply some bio-based materials derived from organisms or their deep-processed products to the preparation of fully biodegradable materials. For example, they combine some directly processable bio-based resins (such as PLA, PHBV, PBS) with Some biomass materials (such as starch, cellulose, straw, etc.) that need to be dispersed and plasticized are mixed to prepare fully bio-based and fully biodeg...
