specific Embodiment approach 1

[0007] Embodiment 1: The masterbatch of this embodiment is composed of the following components by weight percentage: 5-75% of plant fiber, 5-50% of carbon dioxide polymer, 5-30% of polyvinyl alcohol, 1-10% of compatibilizer and Plasticizer 1-15%. The plant fiber is ultrafinely crushed into 80 mesh, 100 mesh, 120 mesh, 500 mesh or 1000 mesh; the degree of alcoholysis of polyvinyl alcohol is 88-100%; the compatibilizer is maleic acid, silicone oil, r- One or more of aminopropyltriethoxysilane and stearic acid; the plasticizer is one or more of glycerol, diethylene glycol, ethylene glycol, propylene glycol and sorbitol.

specific Embodiment approach 2

[0008] Embodiment 2: The masterbatch of this embodiment is composed of the following components by weight percentage: 10-40% of plant fiber, 10-50% of carbon dioxide polymer, 10-30% of polyvinyl alcohol, 1-10% of compatibilizer and Plasticizer 1-15%. The masterbatch of this embodiment can be processed into film and sheet products.

Abstract

The invention discloses degradable master batch and method for preparing film, sheet material and tableware with master batch as raw material, wherein the master batch comprises the following components (by weight percentage), vegetable fiber 5-75%, carbon dioxide polymer 5-50%, polyvinyl alcohol 5-30%, compatiblizing agent 1-10% and plasticizer 1-15%.

Description

Technical field: [0001] The invention relates to a degradable masterbatch made of plant fiber and a process for making film, sheet and tableware with the masterbatch. Background technique: [0002] Environmental protection has become a hot spot of social concern, and many degradable plastic products have emerged. However, most of the current degradable products are not perfect and have failed to achieve the expected results. At present, the degradable masterbatches made at home and abroad include: photodegradable plastics, biodegradable plastics, chemically degradable plastics, and degradable plastics combined by the above three types. Among them, photodegradation is to add a photosensitizer to polyethylene, which will be cracked into small particles and enter the soil under the light for a certain period of time. Over time, not only the soil cannot be improved, but the soil will deteriorate instead. The reason is that the polyolefin material is few in the soil. It cannot b...
