Abstract
The composition of both photodegradable and biodegradable polyethylene mother material includes polyethylene, modified starch, photosensitizer, degradation control agent and talcum powder. Said composition of the mother material made up by using aluminium-titanium compounded coupling agent to treat starch and talcum powder is simple and good in dispersion, and the double degradable plastic product made up by using said mother material possesses excellent mechanical property and degradation property, mainly can be used for making double degradable plastic packaging film, disposable plastic tableware and mulch film, etc..
Description
The present invention relates to a kind of light, bio-degradable polyethylene masterbatch.
The various polyethylene films of existing use in physical environment, self are difficult to decompose, and are scattered in soil and the physical environment, cause the pollution of soil and environment.Therefore, carry out number of research projects both at home and abroad, developed degradative plastics.Particularly light, biodegradation plastic become the focus that people note.Light, the biodegradation plastic of present development.Most of metatitanic acid vinegar coupling agent and polyethylene wax of adopting handled starch, and be poor by a coupling effect, thereby the biodegradable plastic goods mechanical property and the degradation property that get are poor.
The object of the present invention is to provide the good plastics film available light of a kind of mechanical property and degradation property, bio-degradable polyethylene masterbatch.
Light of the present invention, the raw materials used component of bio-degradable polyethylene masterbatch comprise (weight part meter):
Polyethylene: 30-50 part;
Treated starch: 10-40 part;
Photosensitizers: 0.01-0.4 part;
Degraded control agent: 0.01-0.4 part;
Talcum powder: 10-50 part.
The polyethylene that the present invention uses is new LDPE (film grade) and linear low density polyethylene, and the two is than being 1: 1.
The photosensitizers that uses among the present invention is ferric oxide, Acetyl Acetone iron.
The present invention's control agent of degrading is a benzophenone.Phenolic antioxidant, antioxidant 264, antioxidant 1010 etc.
The treated starch that the present invention uses is polyethylene fat mixing making in super mixer of coupling agent and the 0.2%-5% of starch 0.2%-5% by weight.
The talcum powder granularity that the present invention uses is 1250 orders-2500 orders, and handles in the 0.2%-5% aluminium titanium composite coupler modification of talcum powder weight.Mixing making in super mixer.
The invention has the advantages that with aluminium titanium composite coupler and polyethylene wax starch and talcum powder are carried out modification, the mother raw material degradable component that makes is simple, good dispersity, biodegradable plastic goods mechanical property and the degradation property made are good, have reduced production cost simultaneously.
The present invention and light, bio-degradable polyethylene masterbatch can be with making biodegradable plastic packing film, disposable tableware and mulch film etc.
Describe embodiments of the invention below in detail:
Embodiment 1:
New LDPE (film grade): 5 parts;
Linear low density polyethylene: 15 parts;
Treated starch: 35 parts;
