Problems solved by technology

[0003] The products prepared by the existing polylactic acid resin, the preparation cost is too high, due to its poor mechanical properties and low relative molecular weight, the scope of application is limited, and the heat resistance is poor, which greatly shortens the duration of its use. Therefore, for These deficiencies are corrected, need to prepare a kind of novel polylactic acid resin

Abstract

The invention relates to the technical field of polylactic resin, and particularly relates to polylactic resin prepared from various plant materials and a preparation method of the polylactic resin. The polylactic resin is composed of the following raw materials: polylactic acid, a chain extender, a heat-resistant agent and a blend. According to the polylactic acid resin prepared from various plant materials, corn and potato are processed to produce a large amount of starch, the polylactic acid preparation cost is reduced, the characteristics of high stretchability and good transparency are more suitable for polylactic acid resin preparation, polylactic acid oligomers obtained through direct polycondensation are treated with the chain extender, polylactic acid with high relative molecularmass is obtained, the heat resistance of polylactic acid resin can be improved through compounding of a heat-resistant agent and polylactic acid, the mechanical properties are greatly improved at thesame time, and through addition of the blend, on the premise that the biodegradability of polylactic acid is not damaged, polylactic acid and biodegradable macromolecules are blended and modified, sothat the rigidity and toughness of the modified PLA material can be adjusted.

Description

technical field [0001] The invention relates to the technical field of polylactic acid resins, in particular to a polylactic acid resin prepared from various plant materials and a preparation method thereof. Background technique [0002] Polylactic acid is a new type of biodegradable material. It is made of starch raw materials proposed by renewable plant resources. The starch raw materials are saccharified to obtain glucose, and then fermented by glucose and certain strains to produce high-purity lactic acid. Polylactic acid with a certain molecular weight is synthesized by chemical synthesis, which has good biodegradability, can be completely degraded by microorganisms in nature after use, and finally produces carbon dioxide and water without polluting the environment. This is very beneficial to the protection of the environment and is a recognized environmental friendly material. Ordinary plastics are still treated by incineration and cremation, causing a large amount of...
