no. 1 Embodiment

[0011] The first specific embodiment of the present invention: a bio-starch degradable plastic masterbatch, which consists of the following components by weight: 77% of bio-refined starch, 8% of toughening agent, 1% of initiator, 5% of modifier, 3% plasticizer, 6% lubricating processing aid. The bio-refined starch is refined to 800-1200 mesh made from potato and corn as raw materials. The toughening agent is ethylene-vinyl acetate copolymer; the initiator is dicumyl peroxide; the modifier is a mixture of stearic acid and maleic anhydride; the plasticizer is glycerin; the lubricating processing aid is PE wax . The content of stearic acid in the modifier accounts for 4% of the total content, and the content of maleic anhydride accounts for 1% of the total content.

no. 2 Embodiment

[0012] The second specific embodiment of the present invention: a bio-starch degradable plastic masterbatch, which consists of the following components by weight ratio: 80% of bio-refined starch, 10% of toughening agent, 1% of initiator, 4% of modifier, 2% plasticizer, 3% lubricating processing aid. The bio-refined starch is refined to 800-1200 mesh made from potato and corn as raw materials. The toughening agent is POE; the initiator is dicumyl peroxide; the modifier is a mixture of stearic acid and maleic anhydride; the plasticizer is ethylene glycol; the lubricating processing aid is white oil. The content of stearic acid in the modifier accounts for 3% of the total content, and the content of maleic anhydride accounts for 1% of the total content.

[0013] The above-mentioned production method of bio-starch degradable plastic masterbatch comprises the following steps: a starch refinement process, a starch high-speed mixing process; wherein, in the starch refinement process...

Abstract

The invention relates to biological starch degradable plastic master batches which are composed of the following components by weight percent: 70-80% of biological refined starch, 7-10% of a toughening agent, 0.5-2% of an initiator, 4-7% of a modifier, 1-3% of a plasticizer and 3-6% of a lubricating processing adjuvant. The biological refined starch is refined into 800-1200 meshes by taking yams and corns as raw materials. During the production process, the biological starch degradable plastic master batches are prepared by a starch refining procedure and a starch high-speed mixing procedure,and then the master batches are prepared into a degradable plastic product. A biological (yams and corns) starch degradable plastic sheet has the same physical property and mechanical property as thecommon plastic product and other special properties, and has simple process and lower cost; and the degradable plastic sheet can be degraded in a natural environment, thus reducing environmental pollution, relieving environmental contradiction, and meeting the requirements of reduction, reclamation and harmlessness in a method for controlling pollution of solid wastes.

Description

technical field [0001] The invention relates to a masterbatch of plastic products produced by utilizing biostarch, and derivative products thereof. Background technique [0002] Plastic, as a new material, has developed vigorously since the middle of the 20th century, and has shown a continuous growth trend year by year. Now, plastic products have been widely used in various industries and fields of human activities, and it is becoming more and more difficult to leave plastic products in our daily life. While the plastics industry is developing, plastic materials also encounter two problems: (1) limited resources. Polymer compounds such as plastics are mainly derived from petroleum, and petroleum is a non-renewable resource, which has been gradually depleted on the earth. (2) Pollution to the ecological environment. At present, the world's plastic production has reached 200 million tons, and my country's plastic production is also about 20 million tons per year. More and...
