Abstract

The invention relates to antibacterial polyurethane. The antibacterial polyurethane comprises the following components in parts by weight: 60 parts of polyurethane and 0.1-0.25 part of a composite antibacterial agent; the composite antibacterial agent is prepared from the following raw materials in percentage by weight: 40% of an organic bacteriostatic agent, 35% of nano silver oxide and 25% of chitosan; the organic bacteriostatic agent is prepared from the following raw materials in percentage by weight: 48% of neem oil, 22% of a herba taraxaci extract and 30% of a dark plum extract. According to the antibacterial polyurethane provided by the invention, the composite antibacterial agent is added into polyurethane, so that the bacteriostatic effect of polyurethane is improved, and the antibacterial polyurethane has an excellent inhibiting effect on staphylococcus aureus, colibacillus and candida albicans.

Description

technical field [0001] The invention belongs to the field of plastics, and in particular relates to an antibacterial polyurethane. Background technique [0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound. Polyurethane material has a wide range of uses and can replace rubber, plastic, nylon, etc. It is used in airports, hotels, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, colored stone art, parks, etc. Many public facilities are made of polyurethane materials, but now the environment is seriously polluted and bacteria are everywhere. When using these public facilities, cross-infection often occurs and endangers human health. Contents of the invention [0003] The purpose of t...
