Abstract
The invention provides a degradable plastic which is composed of, by weight, 30 to 70 parts of synthetic resins, 50 to 70 parts of plant fiber starch, 1 to 5 parts of photo-sensitizer and 5 to 20 parts of additives. The synthetic resins are selected from the combination of propene polymer (PP) resins and polylactic acids; the plant fiber starch is selected from garden wastes, in particular to leaves, weeds, limbs and the like; the additives include plasticizers, lubricants and heat stabilizers; the plasticizers are selected from one of tributyl citrate, mineral oil, acetic acid tributyl ester, urea and formamide; the lubricants are magnesium stearate; and the heat stabilizers are triphenyl phosphate. The degradable plastic has the advantages of biodegradation and light degradation, and the degradation is thorough; the starch is selected from the plant fiber starch, and the garden wastes are used, accordingly, both environmental problems are solved, and the cost of the degradation plastic is reduced; and components are simple, the cost is low, and the plastic is easy to produce.
Description
Technical field
The present invention relates to a kind of degradable plastics.
Background technology
Plastics are a kind of general and durable materials, but the pollution that plastics cause is also very fearful, and white pollution has caused irreversible injury to environment; Therefore degradable plastic product is the focus of researching and developing at present always now, and various product innovations emerge in an endless stream, and are the photosensitised degradation material the earliest; Recently research and development focus is the starch-based degrading plastics, i.e. biodegradable plastic, but degradable plastics now may not be accomplished to degrade fully; Biodegradable plastic is in arid or lack some Special Areass such as soil and be difficult to degraded, and photodegradable plastics can not form degraded when being buried in the soil, and makes the degradable high polymer material that degradable plastics uses now and be polycaprolactone (PCL); POLYACTIC ACID (PLA), poly butylene succinate (PBS), price is expensive; How can utilize existing material, especially rejected material is produced a kind of degradable plastics; Then can reduce cost greatly, can also reduce pollution environment.
Summary of the invention
The purpose of this invention is to provide a kind of degradable plastics, degraded is thorough, and cost is lower, has concurrently photosensitive and biodegradation character.
For realizing above-mentioned goal of the invention, technical scheme of the present invention is following: a kind of degradable plastics is made up of the component of following weight part:
Said synthetic resins is selected the combination of pp resin and POLYACTIC ACID for use.
Said made from plant fiber starch is a garden waste, is specially leaf, weeds, limb etc.
Said auxiliary agent comprises: softening agent, lubricant, thermo-stabilizer.
Said softening agent is selected any in tributyl citrate, MO, acetate tri-n-butyl, urea, the methane amide for use.
Said lubricant is a Magnesium Stearate.
Said thermo-stabilizer is a triphenyl phosphite.
Further, a kind of degradable plastics is made up of the component of following weight part:
Said photosensitizers is the organic cpds or the salt of transition metal.
The invention has the beneficial effects as follows: 1 this kind degradable plastics has the characteristics of biological degradation and photosensitised degradation concurrently, and it is more thorough to degrade; 2 starch are selected made from plant fiber starch for use, have utilized garden waste, have both solved an environment difficult problem, have reduced the cost of this kind degradable plastics again; 3 components are simple, with low cost, be easy to make.
Embodiment
Below principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
