Abstract

The invention discloses a biodegradable peanut protein plastic with a long service life. The biodegradable peanut protein plastic comprises the following raw material in parts by weight: 30 to 35 parts of poly (3-hydroxybutyrate-co-3-hydroxyvalerate) PHBV, 55 to 60 parts of modified-beta-hydroxybutyric acid, 15 to 20 parts of peanut protein powder, 15 to 18 parts of nano cellulose whiskers, 3 t o 5 parts of amylase, 1.1 to 1.3 parts of a silane coupling agent KH590, 2 to 3 parts of sodium lactate, 0.5 to 0.8 parts of sodium dehydroacetate, 1.7 t o 2.3 parts of dioctyl terephthalate DOTP, 2 to 4 parts of octyl epoxy stearate, 25 to 28 parts of carbon black N550, 12 to 16 parts of ground calcium carbonate, 4 to 7 parts of kaolin, 10 to 12 parts of hard pottery clay, and 0.7 to 0.9 parts of an antioxidant. The peanut protein plastic can be biologically degraded into low molecular compound, is high in flexility, good in impact resistance and oxidation resistance, low in water absorption, and low in complete degradation velocity, and the service life of the biodegradable peanut protein plastic can be prolonged.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a biodegradable peanut protein plastic with long service life. Background technique [0002] As one of the most widely used materials, plastic is essential in daily life. While its plasticity, stability and economical practicability bring convenience to people, it also causes waste plastic products—that is, “white garbage”—to harm the environment. heavily polluted. Biodegradable plastics can be completely decomposed into low molecular compounds under the action of microorganisms. Its products are convenient for storage and transportation, and have a wide range of applications. They can be used not only in agricultural mulch films and packaging bags, but also in the field of medicine. Vigorously developing biodegradable plastic products can reduce the generation of "white garbage" and reduce its pollution to the environment, which has significant social, environmental and econo...
