Problems solved by technology

The currently used biodegradable plastics are mainly made by blending general-purpose plastics such as polyethylene and polypropylene with degradable polymers such as starch under certain conditions. The starch content in thin products is about 30%, and the starch content in thick products At about 50%, the processing technology of this degradable plastic is difficult, the production cost is high, the degradation time of the product is long, and the degradation is not complete, and its biodegradability and mechanical properties are still difficult to meet various use requirements; therefore, some It is necessary to study a completely biodegradable plastic to solve the above problems

Abstract

The invention discloses an environment-friendly completely biodegradable plastic and a preparation method thereof. The environment-friendly completely biodegradable plastic is prepared from the following raw material components in parts by mass: 30-35 parts of a plant mixed particle fermentation product, 5-7 parts of an initiator, 1-2 parts of a plasticizer and 0.5-0.8 part of an active agent, wherein the plant mixed particle fermentation product is prepared by mixing and fermenting corncob particles, seaweed particles, wheat bran, wheat straw particles and palm fibers. The preparation method comprises the following steps: S1, weighing the corncob particles, the seaweed particles, the wheat bran, the wheat straw particles and the palm fibers in proportion; s2, cleaning and airing the raw materials; s3, mixing and stirring the raw materials to obtain a mixed material; s4, fermenting the mixture to obtain a plant mixed particle fermentation product; s5, heating the mixture to a molten state, adding the initiator, the plasticizer and the active agent in proportion, and uniformly stirring and extruding the product.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to an environment-friendly fully biodegradable plastic and a preparation method thereof. Background technique [0002] With the rapid development of the plastics industry, the corresponding "white pollution" situation is also becoming more and more serious. Facing the global energy crisis and increasing environmental pollution, there is an increasingly urgent need for new plastic materials that not only have excellent plastic properties but are also degradable. The currently used biodegradable plastics are mainly made by blending general-purpose plastics such as polyethylene and polypropylene with degradable polymers such as starch under certain conditions. The starch content in thin products is about 30%, and the starch content in thick products At about 50%, the processing technology of this degradable plastic is difficult, the production cost is high, the degradation time of th...
