Abstract

The invention discloses a degradable plastic which consists of the following components in parts by weight: 35-50 parts of polypropylene, 10-20 parts of plant fiber starch, 10-20 parts of hydroxypropyl methyl cellulose, 4-8 parts of paraffin wax, 2-10 parts of a color master batch and 6-12 parts of glycerinum. The degradable plastic disclosed by the invention has properties such as toughness and ductility which are generally identical to those of existing plastics, also has the characteristic of degradability, and can be decomposed gradually and completely under the condition of outdoor exposure; and in addition, the plastic is simple in preparation process, low in preparation cost and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the field of materials, in particular to a degradable plastic. Background technique [0002] Due to the low processing cost, plastics are widely used, but non-degradable and refractory plastics also cause extremely serious plastic pollution, and there are various corresponding substitutes, but basically they cannot achieve good results because of the high cost. substitute. [0003] Therefore, prior art also needs further development and improvement Contents of the invention [0004] The purpose of the present invention is to provide a degradable plastic, aiming at realizing replacement of plastic, and having degradability. [0005] Technical scheme of the present invention is as follows: [0006] A degradable plastic, wherein, by weight, it consists of the following components: [0007] 35-50 parts of polypropylene; [0008] 10-20 parts of plant fiber starch; [0009] 10-20 parts of hydroxypropyl methylcellulose; [00...
