Abstract

The invention relates to an economical environment-friendly degradable plastic sheet and a preparation method thereof. The economical environment-friendly degradable plastic master batch is composed of polyolefin, calcium carbonate, a photosensitizer, an oxidative degradation agent, a biodegradation control agent, a processing assistant, a coupling agent, a heat stabilizer, a photostabilizer and an antioxidant. The sheet is prepared from the following raw materials in parts by weight: 30 parts of economical environment-friendly degradable plastic master batch, 60-100 parts of activated calcium carbonate, 10-20 parts of short fiber and 0.5-2.5 parts of coupling agent. The invention provides a production method of the economical environment-friendly degradable master batch. The master batch can be mixed with other plastics to process degradable plastic products. Compared with the prior art, the technique for processing the economical environment-friendly degradable sheet adopts abundant calcium carbonate and chopped fibers as the processing raw materials, and thus, ensures the operating requirements of the product on the premise of lowering the production cost. The sheet has high chemical stability (high temperature resistance, water resistance, oil resistance and the like), can be used for packaging in the fields of food, toys, hardware, electronic products and the like, has the advantages of high biological decomposition speed, low cost and the like, and can easily implement industrialization.

Description

technical field [0001] This patent relates to the technical field of degradable plastics, in particular to an economical and environment-friendly degradable plastic masterbatch and a method for preparing the sheets thereof. Background technique [0002] In recent years, degradable plastics have attracted widespread attention as an effective means to alleviate environmental pollution. However, due to the performance indicators of degradable plastics compared with traditional plastics, there is still a certain gap, and the production cost is high, so its market acceptance is not very high, so it is difficult to promote and use. [0003] Compared with the prior art, the present invention has the following advantages: [0004] (1) The appearance keeps the surface of the material clean, non-toxic, harmless, and odorless, and all food-grade raw materials are used, which are hygienic and clean; [0005] (2) The product has sufficient mechanical properties and chemical stability s...
