Problems solved by technology

[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 Bottlenecks that need to be solved urgently in the popularization and application of degradable plastics
In addition, in order to meet the needs of processing plastic products of various colors, it is also necessary to be able to produce highly filled and degradable plastics with colors, while industrial dyes often produce a lot of pollution during the preparation and production process, which does not meet environmental protection requirements. And the dyed plastic products may be poisonous to people due to the use of industrial pigments when used. Therefore, safe and non-toxic colored degradable plastics have become a very necessary material in production.

Abstract

The invention discloses plant-dyed highly-filled degradable plastic. The plant-dyed highly-filled degradable plastic is prepared from, by weight, 25-80 parts of biodegradable materials, 30-75 parts of filling powder, 2-10 parts of auxiliaries and 5-10 parts of plant coloring agents; the plant coloring agents adopt one of curcumin, gardenia yellow, carthamin, quercitrin, munjistin, indigotin, gardenia blue, chlorophyll, capsanthin and logwood black, and the plant degradable materials comprise any one of poly butylenes succinate, polyethylene terephthalate and polylactic acid. The plant-colored highly-filled degradable plastic is easy to degrade, clear in color and suitable for being applied to production and manufacture of various plastic products.
