Abstract

The invention discloses highly-filled degradable plastics. The highly-filled degradable plastics are prepared from, by weight, 25-80 parts of biodegradable materials, 30-75 parts of filler powder and 2-10 parts of auxiliaries. The biodegradable materials comprise any one of poly(butylene succinate), poly(terephthalic acid adipic acid butyleneterephthalate) and polylactic acid. The filler powder comprises any one of wood powder, modified starch, modified calcium carbonate, modified talcum powder, modified fly ash, montmorillonoid and kaolin. The highly-filled degradable plastics are low in cost, easy to degrade, good in plasticity and suitable for being applied to producing and manufacturing of plastic products.

Description

technical field [0001] The invention relates to a highly filled degradable plastic, which belongs to the technical field of plastic preparation. Background technique [0002] At present, the huge amount of plastic manufacturing and waste has caused irreversible pollution and damage to the environment on which we live. In order to alleviate the shortage of petroleum resources and reduce the harm of white pollution, degradable plastics have become a hot spot for researchers, and research on degradable materials has achieved certain results. However, the price of degradable materials is relatively high, and reducing the cost of degradable plastics has become a The bottleneck that urgently needs to be solved in the popularization and application of degradable plastics. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a highly filled degradable plastic with simple raw materials and low cost. [0004] For solving above techni...
