Problems solved by technology

[0004] In addition, the degradation of this degradable plastic film requires certain fixed conditions, and the environment after the plastic film is discarded is either placed in a closed garbage disposal system or exposed to a natural environment with unstable conditions. The fixed conditions required for the degradation of this plastic film, these degradable plastics in most cases, whether in the garbage disposal system or in the natural environment, cannot be degraded well due to limited conditions
In the prior art, there is no degradable plastic film that can guarantee degradation in the environment after disposal

Abstract

The invention discloses a preparation method for a regenerated nanometer flame retardant plastic, wherein the regenerated nanometer flame retardant plastic is characterized by comprising the following raw materials in parts by weight: 45-60 parts of plant fiber starch, 4-6 parts of glycerinum, 40 parts of polyethylene, 20-40 parts of polylactic acid, 60-80 parts of synthetic resin, 10-15 parts of an additive, 5-8 parts of pulullan, 2-4 parts of an antioxygen agent, 1-1.5 parts of an ultraviolet light absorber and the like.

Description

technical field [0001] The invention relates to a plastic film, in particular to a preparation method of a recycled nano flame-retardant plastic. Background technique [0002] As we all know, the plastic bag made of plastic film is light, thin, impermeable, strong, and low in cost. It is a good packaging material. The amount of bags is increasing, and the waste plastic bags after use are not easy to recycle and degrade. A large number of waste plastic bags have become a serious problem that pollutes the environment. In order to reduce the pollution of plastic films to the environment, people have developed some environmentally friendly green degradable plastic films, such as: patent number: 200710144500.2, paper-like degradable plastic film and its manufacturing process; and patent number: 201110051187.4, which can be completely biodegradable A method for plastic resins and film-like products thereof. This type of degradable plastic film is composed of film-grade plastics ...
