Processing process for degradable plastic

Abstract

The present invention relates to the technical field of plastic processing, particularly to a processing process for degradable plastic. The processing process comprises the following steps: (1) mixing a nanometer FeSO4 solution, a Na2CO3 solution and nanometer Si3N4, carrying out ultrasonic dispersion for 20-30 min at a frequency of 400-500 Hz, conducting drying at a temperature of 40-50 DEG C, grinding the dried mixture into powder, placing the powder into a muffle furnace, conducting sintering at a temperature of 400-500 DEG C in the atmosphere of N2, then adding chitosan, CaCO3, an ethylene propylene diene monomer copolymer, poly-beta-hydroxybutyrate and bifenthrin, carrying out mixing, performing grinding into powder, adding a sodium tripolyphosphate solution and a guanidine hydrochloride solution, conducting uniform stirring, and performing drying to obtain mixed powder; and (2) mixing epoxy resin, glycerol, polylactic acid and the mixed powder obtained in the step (1), conducting extruding by using a double-screw extruder, and performing molding in an injection molding machine. The prepared degradable plastic is not prone to mildew and aging and cannot be bitten by insects.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a processing technology for degradable plastics. Background technique [0002] Plastic is the most common and commonly used material in daily life. In order to ensure the sustainable development of the environment, it is necessary to reduce the amount of plastic used, especially in food, pharmaceutical packaging, and shopping malls. Plastic products are unavoidable. In order to reduce environmental impact Pollution, degradable plastics enter people's lives, but most degradable plastics are prepared from waste plant fibers, starch and other raw materials, and the above raw materials are not only in the process of use, but also have poor toughness, poor load-bearing capacity, and heat resistance Poor, easy aging, damp, moldy and damaged by other insects, inconvenient use and storage, therefore, the prior art needs further improvement.
