Abstract

The invention provides environment-friendly degradable antimicrobial plastic and a preparation method thereof. The plastic is prepared from, by weight, 20-35 parts of polyvinyl chloride, 3-10 parts offlax fibers, 5-15 parts of polyphenyl ester, 4-10 parts of 50wt% ethanol water extract of asarum sieboldii, 2-8 parts of 50wt% ethanol water extract of ligusticum wallichii, 1-9 parts of 50wt% ethanol water extract of galla chinensis, 5-11 parts of lauric acid monoglyceride, 18-26 parts of polycaprolactone, 15-27 parts of acetylated starch, 5-12 parts of thermal stabilizer, 3-9 parts of plasticizer and 4-10 parts of filler. The prepared environment-friendly degradable antimicrobial plastic has the advantages of being good in antibacterial performance, high in resistance to external force destruction, environmentally friendly, degradable and capable of reducing environmental pollution.

Description

technical field [0001] The invention relates to the field of materials, in particular to an environmentally friendly degradable antibacterial plastic and a preparation method thereof. Background technique [0002] Plastic products are important organic synthetic polymer materials with a wide range of applications, occupying an important position in various fields such as agriculture, industry, construction, packaging, defense cutting-edge industries and people's daily life. For example, shed film, mulch film, sunshade net and insect net used in agricultural facilities are all plastic products. In the great development process of the construction field, the contribution of plastics is also indispensable, such as plastic doors and windows, plastic pipes and so on. Plastics are also widely used in medical and food packaging, such as controlled organs and artificial skin made of plastic, as well as syringes, infusion bags, and food packaging bags. plastic While the widespread ...
