Abstract
The degradable plastic film consists of polypropylene or polyethylene, peroxidant, plasticizer, inner and outer lubricant, transparent agent and manganese dioxide in the weight ratio of 100 to 0.1-0.5 to 5-55 to 0.1-2.0 to 0.1-0.3 to 0.1-1.0. The plastic film is easy to degrade under the irradiation of ultraviolet ray, and this can avoid environmental pollution.
Description
The present invention relates to a kind of plastics film of easy degraded.
Existing plastics film is formed by resin [as polyethylene or polypropylene etc.], antioxidant [as CA and dihydroxyphenyl propane etc.], softening agent [as o-phthalic acid dibutyl ester, the hot fat of epoxystearic acid, Triphenyl phosphate (TPP), single stearic acid glycerine lipoprotein etc.], inside and outside lubricant agent [as Zinic stearas or barium stearate], transparent base blowings such as [as cadmium stearates].As existing low temperature resistant anti-aging agricultural plastic film prescription is polyvinyl chloride [100 (parts by weight, down with)], dihydroxyphenyl propane [0.5], antioxidant CA[0.3] o-phthalic acid dibutyl ester [47], the hot fat [5] of epoxystearic acid, Triphenyl phosphate (TPP) [0.8], single stearic acid glycerine lipoprotein [0.5] barium stearate [0.5], Zinic stearas [0.1] cadmium stearate [0.3].The above-mentioned plastics film purposes of existing plastics film is very extensive, can be used as wrapping material, convenient bag, agricultural film etc.Because the plastics film purposes is extensive, the depleted plastics film increases thereupon, except that the secondary masterbatch is made in partially recycled utilization, a considerable amount of depleted plastics films are dropped, owing to select for use aging-resistant polyethylene, polyvinyl chloride to make raw material, wherein add antioxidant again, make it be difficult to degraded for a long time, cause environmental pollution easily, be also referred to as " white pollution ".
The plastics film that the purpose of this invention is to provide a kind of easy degraded, under uviolizing or passing in time, degraded easily can overcome the above-mentioned shortcoming of prior art.
A kind of plastics film of easy degraded, it is characterized in that being made up of polypropylene or polyethylene, peroxidation agent, softening agent, inside and outside lubricant agent, transparent base and titanium dioxide, their weight percentage scope is respectively 100: 0.1-0.5: 5-55: 0.1-2.0: 0.1-0.3: 0.1-1.0.
Plastics film of the present invention under uviolizing or passing in time degrade easily, can avoid environmental pollution.
Logical below embodiment illustrates the present invention.
Embodiment 1: 100kg polypropylene and 0.2kg calcium peroxide are mixed, add 47kg o-phthalic acid dibutyl ester, the hot fat of 5kg epoxystearic acid, 0.8kg Triphenyl phosphate (TPP), 0.5kg single stearic acid glycerine lipoprotein, [0.5kg] barium stearate, 0.1kg Zinic stearas, 0.2kg cadmium stearate again, the titanium dioxide powder 0.2kg that adds 30 nanometer particle sizes again, by existing method blowing plastics film, products obtained therefrom is under uviolizing, in 95% of 300 days degraded gross weights.
Embodiment 2: in the blowing plastics, polypropylene [or polyethylene] 100kg resin, 0.1kg benzoyl peroxide, add 45kg o-phthalic acid dibutyl ester, the hot fat of 5kg epoxystearic acid, 0.8kg Triphenyl phosphate (TPP), 0.5kg single stearic acid glycerine lipoprotein, 0.5kg barium stearate, 0.1kg Zinic stearas, 0.3kg cadmium stearate 0.3kg again, the titanium dioxide powder 0.5kg in 10 nanometers footpath, by existing method blowing plastics film, products obtained therefrom is under uviolizing, in 97% of 300 days degraded gross weights.
The particle diameter of used titanium dioxide powder is in the scope of 1 nanometer-10 micron among the present invention.The present invention replaces antioxidant of the prior art with the peroxidation agent, easier degraded.
Claims (2)
1, a kind of plastics film of easy degraded, it is characterized in that being made up of polyethylene or acrylic resin, peroxidation agent, softening agent, inside and outside lubricant agent, transparent base and nano titanium oxide, their part by weight is 100: 0.1-0.5: 5-50: 0.1-2.0: 0.1-0.3: 0.1-1.0.
2, the described plastics film of claim 1, Ji Tezheng are that the particle diameter of described titanium dioxide powder is in the scope of 1 nanometer-10 micron.
