Abstract

The invention belongs to the technical field of polylactic acid plastic production, and particularly discloses a polylactic acid degradable plastic which comprises the following components in parts by weight: 40-48 parts of polylactic acid resin, 35-38 parts of polystyrene, 14-18 parts of ramie fibers, 1-2 parts of a compatilizer and 0.5-1 part of a coupling agent. The production process of the polylactic acid degradable plastic is characterized by comprising the following steps: 1) weighing the compatilizer and the coupling agent in parts by weight for later use; and 2) successively drying the polylactic resin, polystyrene and ramie fiber according to the weight parts by using a drying and feeding device, putting the dried polylactic resin, polystyrene and ramie fiber into a raw material mixing device, stirring for 3-5 minutes at the rotating speed of 60-120 r / min of a driving motor, putting the compatilizer and the coupling agent weighed in the step 1 into the raw material mixing device from an additive feeding hopper, and stirring for 10-15 minutes at the rotating speed of 120-180 r / min.

Description

technical field [0001] The technical field of polylactic acid plastic production of the present invention specifically discloses a polylactic acid degradable plastic and a production process. Background technique [0002] In recent years, the use of plastics has been increasing. Due to the difficulty of degrading most plastics, the waste plastic polylactic acid is a new type of plastic material, which is mainly synthesized by lactic acid copolymerization, and can be completely degraded into water and carbon dioxide in soil. It meets the requirements of green environmental protection, causes less damage to the environment, and has broad application prospects. [0003] In order to improve the lack of physical properties of polylactic acid plastics, it is often necessary to stir with other plastic resins, additives, etc., and then melt, extrude and granulate to obtain polylactic acid plastics that are degradable and have excellent physical properties of other plastic resins. d...
