Problems solved by technology

Traditional plastic waste treatment methods such as landfill and incineration have not completely solved the problem of white pollution
[0003] In addition, the surface of many plastic products will breed pathogenic bacteria, which may cause the spread of diseases such as colds, pharyngitis, meningitis, hepatitis, pink eye, skin diseases, tuberculosis, etc.

Abstract

The invention discloses a biodegradable antibacterial plastic. The biodegradable antibacterial plastic comprises the following raw materials: by weight, 60-70 parts of polyether sulfone resin, 10-20 parts of a modified resin, 20-35 of starch, 1-3 parts of a silane coupling agent, 1-5 parts of an antibacterial agent, 5-10 parts of a compatilizer, 1-2 parts of glycerol, 2-4 parts of a degrading promoter, 1-2 parts of carbon black, and 0.1-0.5 part of montan wax. The provided biodegradable antibacterial plastic has high degradability, good light transmittance, good tensile properties and good antibacterial effect due to addition of the antibacterial agent, and is environmentally friendly and healthy.

Description

technical field [0001] The invention relates to a plastic, in particular to a biodegradable antibacterial plastic. Background technique [0002] Disposable plastic products can be seen everywhere in daily life. They are made of polymer compounds such as polystyrene and ethylene, which are difficult to degrade after entering the natural environment, causing serious pollution to the natural environment, also known as white pollution. Traditional plastic waste treatment methods such as burial and incineration have not completely solved the problem of white pollution. [0003] In addition, the surface of many plastic products will breed pathogenic bacteria, which may lead to the spread of diseases such as colds, pharyngitis, meningitis, hepatitis, pink eye, skin diseases, and tuberculosis after contact with people. For this reason, it is required to carry out antibacterial modification treatment on plastic products such as household appliances, chemical building materials, comm...
