Problems solved by technology

The material is flame retardant treated by adding a flame retardant, which has high flame retardant efficiency, mature technology, and low price. However, the added flame retardant generally has a high halogen content. When burning, the plastic is heated to release halogen-containing fumes. It is toxic and will endanger human health and even cause death; the addition of a large amount of flame retardants has a greater impact on the post-processing of the material itself, and the flame retardants are easy to precipitate and cannot maintain flame retardancy for a long time, shortening the service life

Abstract

The invention relates to an antibacterial composite plastic film and a preparation method thereof. The antibacterial composite plastic film is prepared from the following substances in parts by weight: 40 to 60 parts of plastic, 10 to 15 parts of an antioxidant, 5 to 20 parts of polybutylene terephthalate, 25 to 30 parts of an antibacterial compound, 5 to 15 parts of iron oxide and 5 to 10 parts of 1,4-butylene glycol. The antibacterial composite plastic film releases less flue gas in the burning process, has long service life and is relatively wide in application to the fields of buildings, interior decoration and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial composite plastic film and a preparation method thereof. Background technique [0002] With the continuous development of industry, plastics are used more and more widely. Polyethylene, polypropylene, PTT polyester, ABS, etc. are widely used in water-saving irrigation, construction, interior decoration, furniture, electricity, transportation and other industries. However, the content of carbon and hydrogen in plastic is very high, so it is extremely easy to burn, thus limiting the use of plastic. Generally, flame retardant treatment is required when using plastics. At present, the flame retardant is mainly based on the addition of flame retardants. The material is flame retardant treated by adding a flame retardant, which has high flame retardant efficiency, mature technology, and low price. However, the added flame retardant generally has a high hal...
