Plastic membrane product, the plastic sheeting being made such as polypropylene, polyvinyl chloride, polyethylene be difficult under natural environment drop
Solution, after placing for many years, however it remains in natural environment, these plastic sheetings that can not be degraded add the pollution of environment.Mesh
Before, solving the method for this environmental problem mainly has burning method, landfill method and recycling etc..
With the reinforcement of people's environmental consciousness, how to alleviate the topic that white pollution has been people's growing interest, it is degradable
Plastic sheeting is increasingly becoming a kind of development trend of main flow.To implement a scientific outlook on development, resource-conserving is set up and environment-friendly
Type society, people start to take effective measures from source, research and develop degradable plastic sheeting.
The content of the invention
It is an object of the invention to provide a kind of degradable combination film, improve increasingly serious white pollution.
In order to realize the purpose of the present invention, adopt the following technical scheme that：
A kind of degradable combination film, is made up of the raw material of following parts by weight：
Preferably, laminated film is made up of the raw material of following parts by weight：
Preferably, coupling agent is titanate coupling agent.
Preferably, defoamer is the fatty acid ester compounded thing of higher alcohols.
Beneficial effects of the present invention：
The present invention film using poly butyric ester as primary raw material, and compatibility with oxirane, polyvinyl alcohol, starch,
Acetylbutyrylcellulose, chitin, chitosan, with good biodegradability, safety and environmental protection, it is to avoid produce white dirty
Dye；Thin film strength and toughness can be improved again simultaneously.The raw material of the present invention is easy to get, cheap, and preparation technology is simple, has
