PHA modified PPC/TPS biodegradable resin and preparation method thereof

Abstract

The invention discloses PHA modified PPC / TPS biodegradable resin. The biodegradable resin comprises the following raw material components in percentage by weight: 10%-12% of PHA, 40%-45% of PPC, 35%-40% of TPS, and 1%-2% of a plasticizer, with the balance being a compatilizer. The invention also discloses a preparation method of the PHA modified PPC / TPS biodegradable resin. According to the PHA modified PPC / TPS biodegradable resin, the mechanical property of the PPC / TPS biodegradable resin can be greatly improved after the PHA, the plasticizer and the compatilizer are added. Meanwhile, the PHAis a material produced by taking natural plants as raw materials and utilizing a biological fermentation engineering technology, so that the content of biomass in the blend can be greatly increased,and the blend is easier to degrade. PHA has good heat preservation and water insulation performance, after PHA is added into the PPC / TPS biodegradable resin, the PHA, the plasticizer and the compatilizer have a synergistic interaction effect, the waterproofness of a prepared film is greatly enhanced, and the film can be used for various products.

Description

technical field [0001] The invention belongs to the technical field of biodegradable materials, and in particular relates to a PHA-modified PPC / TPS biodegradable resin and a preparation method thereof. Background technique [0002] With the acceleration of urbanization in our country, the increasingly serious pollution has been paid more and more attention by human beings. Especially wastes such as plastics, disposable lunch boxes, etc., are difficult to deal with due to their refractory characteristics. At present, it is generally disposed of through landfill, but such materials are difficult to degrade and be absorbed by the soil in the natural state, which requires a large amount of resources for disposal on the one hand, and destroys the ecological balance on the other hand. [0003] Therefore, the national policy requires that industrial production needs to be green and environmentally friendly, and the products produced also need to be green and environmentally friend...

AI Technical Summary

Problems solved by technology

Especially waste such as plastics, disposable lunch boxes, etc., due to their non-degradable characteristics, their disposal becomes difficult

Now, it is generally disposed of by landfill, but this kind of material is difficult to degrade and be absorbed by the soil in the natural state, which requires a lot of resources for disposal on the one hand, and destroys the ecological balance on the other hand.
