Abstract
A mother particles for the photogradable polypropylene plastics is prepared from polypropylene resin (35-50 wt.%), modified calcium carbonate (20-35), talc powder (20-30), coupling agent (1-2), stearic acid (1-2), lubricant (1-2), and light and oxygen sensitizer (0.3-2). Its advantage is high degradation speed under action of light, oxygen and high temp.
Description
Technical field
The present invention relates to a kind of plastic master batch, particularly a kind of photodegradation acrylic plastering master batch.
Background technology
Plastics obtain application more and more widely in life at present, particularly be unable to do without Plastic Packaging Materials especially in food service industry, the plastics of the existing overwhelming majority all are the plastics of non-degraded, and because the plastics that daily life is used disperse and usage quantity is big, and the costliness of recovery and processing cost, can't recycle, thereby cause white pollution easily.
Summary of the invention
The objective of the invention is to solve plastics in the prior art and in life, obtain more and more widely application, particularly be unable to do without Plastic Packaging Materials especially in food service industry, the plastics of the existing overwhelming majority all are the plastics of non-degraded, and because the plastics that daily life is used disperse and usage quantity is big, and the costliness of recovery and processing cost, can't recycle, thereby cause the problem of white pollution easily.Technical solution of the present invention design photodegradation acrylic plastering master batch, it is characterized in that: constitute by following constituent and weight percent, acrylic resin 35%---50%, modified calcium carbonate 20%---35%, talcum powder 20%---30%, coupling agent 1%---2%, stearic acid 1%---2%, lubricant 1%---2%, light-oxygen sensitizer 0.3%---2%.Advantage of the present invention is to quicken the degraded of plastics, the white pollution that the control plastics bring by under the effects such as light, oxygen, heat under state of nature.
Embodiment
Get 40 kilograms of acrylic resins, 28 kilograms of modified calcium carbonates, 25 kilograms of talcum powder, 2 kilograms of coupling agents, 2 kilograms of stearic acid, 2 kilograms of lubricants, 1 kilogram of light-oxygen sensitizer, earlier 28 kilograms of modified calcium carbonates and talcum powder are added 2 kilograms of mixed back adding coupling agents for 25 kilograms, 2 kilograms of stearic acid, 2 kilograms of lubricants, 1 kilogram of light-oxygen sensitizer, add 40 kilograms of acrylic resins at last, above-mentioned materials is by the twin-screw set granulation, and air-cooled post-treatment becomes 1000 kilograms photodegradation polypropylene agglomerate, can be when producing by photodegradation acrylic plastering 20%---30% adds in the polypropylene, can be made into then to have certain inflexible, cold-and-heat resistent, transparent food package box.Behind product abandonment, under the effect of sunlight, progressively become small molecules by macromole, in appearance,, finish degraded from complete broken to cracking.
