Description
Technical field
The present invention relates to a kind of biodegradable additive, the biodegradable additive of more particularly to a kind of cupric, it can
Conventional nonbiodegradable plastic products biodegradability is assigned, the invention further relates to the plastics system containing the additive
Product, the particularly polyethylene film material containing the additive.
Background technology
For plastic products because good and cheap, durable in use and anti-microbial property is good, is widely used in food packaging applications.However, with
Widely using with plastic products such as plastic convenient bag, plastic sheetings, " white pollution " problem also increasingly highlights.This is due to
The inherent life-span of plastic products is considerably longer than its service life (from finished product to complete natural decomposition).In plastics it is durable
Property, causes as do not handled it, is present in nature and cumulative for a long time.Solution to this problem master at present
There is buried and burning etc..Buried to occupy cultivated land, polluted underground water is former, changes soil texture, influences plant normal growth, and into
This is higher；Burning is current the most widely used white-pollution control method, and speed is fast, and cost is low, but significant drawback is band
Atmosphere pollution is additionally carried out.
The technical scheme of biodegradable plastics has been proposed, because biodegradable plastics can be in natural conditions such as
Natural degradation under the influence of ultraviolet light, rainwater etc., and pollutant is not produced after degrading, therefore can fundamentally solve this
Problem.The biodegradable plastics developed has PLA, poly butylene succinate, poly-succinic adipic acid butanediol
Ester, polyadipate mutual-phenenyl two acid bromide two alcohol ester etc..Although biodegradable plastic has the following advantages that：(1) volume after degrading
Reduce, can save and take landfill yard soil, economize the land resource；(2) do not have to burn, reduce noxious gas emission；(3) can be made into
Compost back to nature.But there is following defect in existing biodegradable plastics：(1) high expensive, correspondingly, its valency
Lattice are also higher than common plasticses 2~6 times；(2) physical and mechanical property is poor.Its tensile strength, elongation at break, bursting and tear are strong
Degree, optical clarity, wet strength etc. all do not reach the requirement of application.2 points of the above has had a strong impact on biodegradable plastics product
Application.
In consideration of it, propose following problem：A kind of biodegradable additive is developed, by its use, makes to include common modeling
The inherent life-span of various plastic products including material and service life are effectively combined, both assigned it is traditional can not biology
