Abstract

The invention discloses biodegradable peanut protein plastic. The biodegradable peanut protein plastic comprises the following raw materials in parts by weight: 30-35 parts of poly(hydroxybutyate-co-hydroxyvalerate) (PHBV), 55-60 parts of modified poly-beta-hydroxybutyrate (PHB), 15-20 parts of peanut protein powder, 2-2.4 parts of jute fiber, 3-4 parts of silk fiber, 1.1-1.3 parts of a silane coupling agent A-151, 2-3 parts of sodium lactate, 0.5-0.8 part of sodium dehydroacetate, 1.7-2.3 parts of dioctyl terephthalate (DOTP), 2-4 parts of octyl epoxy stearate, 25-28 parts of carbon black N550, 12-16 parts of heavy calcium carbonate, 4-7 parts of kaolin, and 0.7-0.9 part of antioxidant 1076, wherein modified poly-beta-hydroxybutyrate (PHB) is obtained by blending poly-beta-hydroxybutyrate (PHB) with ethylene-propylene rubber for modifying. The biodegradable peanut protein plastic disclosed by the invention can be degraded into low-molecular-weight compounds by virtue of microorganisms and thus the pollution of 'white garbage' can be effectively avoided; the biodegradable peanut protein plastic has the advantages of high degree of flexibility, good impact resistance and oxidation resistance, low water absorption performance and low completely degradation rate and the service life of the biodegradable peanut protein plastic is prolonged.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a biodegradable peanut protein plastic. 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 economic benefits. However,...
