Abstract
A degradable and combustible polyethylene plastics is prepared from polyethylene resin (100 pts. wt.), photosensing agent (0.2-1 pts.wt.), ultra-fine inorganic material powder (40-60 pts. wt.) and surface treating agent of said inorganic material powder (1-2 pts. wt.). It can be used to make film or package bag, and features photodegradation nature, promoting degradation by burning it, short degradation period, full combustion, and less released harmful gas when it burns.
Description
The present invention relates to a kind of plastics, relate in particular to the degradable and combustible plastics.
Disposable use plastic refuse caused " white pollution " more and more obtains the attention of countries in the world, and at present, the method for administering " white pollution " in the world mainly contains three kinds: recycling, burning disposal and exploitation degradative plastics.To reclaiming in the disposable plastic waste easily and have that salvage material is worth, the general improvement method of recycling that adopts is worth but those are difficult for reclaiming or do not have to recycle, and then general the employing burned or improvement methods such as degraded.
For degradation method, since the eighties, the U.S., Canada, Japan and other countries take the lead in beginning to develop degradable plastics, and obtain certain application achievements, and degradative plastics has become world's hot issue.China also lists degradative plastics in " eight or five ", " 95 " emphasis key scientific and technological projects.But single degradation method methods such as (comprising photodegradation, optically and biologically degrading) that adopts, the light application time of thorough degraded will be rectificated (about 40-50 days).And generally speaking, after plastic refuse was discarded, in occurring in nature exposure duration short (1-5 days usually), thereby actual light can't realize thorough degraded according to deficiency of time.And this plastic refuse is if adopt burning disposal, equally with the common polythene plastics will produce deleterious dust and toxic gas, causes atmospheric secondary pollution.
In fact, it is that the master comes treating refuse (comprising plastic refuse) that a lot of countries still adopt at present with the incinerating method, the sealed polyethylene plastic that it is reported Japan's exploitation, can reduce during burning atmospheric pollution, but this product belongs to filled-type, its effect only is embodied on the decrement of plastic material, and it is bigger when burning owing to molecular weight, the shortcoming that still has incomplete combustion and have certain obnoxious flavour to produce, and this material is as buried without burning disposal, because its non-degradable still has " white pollution ", thereby also there is bigger deficiency.
The object of the present invention is to provide a kind of vinyon of degradable and combustible.
Adopt in the compositing formula of the present invention:
1, polyethylene is made the main material of compositing formula, can adopt between high density polyethylene(HDPE) (HDPE), new LDPE (film grade) (LDPE) and linear polyethylene (LLDPE) and they both or the three combination with certain ratio; 2, rare earth or transition metal complex class are made photosensitizers, and such photosensitizers can promote the quick degraded of polythene material when illumination, can also be as the burning promotor of plastic material when burning; 3, adopt the ultrafine powder inorganic materials, as the degraded and the burning promotor of plastic material, this ultrafine powder inorganic materials is handled through special surface, and consumption can surpass 30% (weight ratio) in the present technique product; 4, adopt the surface treatment agent of ultrafine powder inorganic materials, the material of this surface treatment agent biologically active, these biologically active substances make the present technique product bury when handling, and biological degradation can take place, concrete treatment technology is, in homogenizer, high-speed stirring 10-30 minute, temperature reaches 100-120 ℃, make its can be in the vinyon material homodisperse, to improve the consistency of inorganic powder material and polythene material, its content in polyethylene film can be reached more than 30%, and the mechanical property of polyethylene film still surpass national standard; This surface treatment agent also can promote the PE material to degrade under microbial process.
Compositing formula of the present invention is as follows: 1, resin: 100 part 2, photosensitizers: 0.2-1 part 3, ultrafine powder inorganic materials: the surface treatment agent of 40-60 part 4, ultrafine powder inorganic materials: 1-2 part wherein:
1, resin is: polyethylene is made the main material (PE) of compositing formula---can adopt between high density polyethylene(HDPE) (HDPE), new LDPE (film grade) (LDPE) and linear polyethylene (LLDPE) and they both or the three combination with certain ratio.
2, the photosensitizers that adopts of compositing formula of the present invention comprises that photosensitizers as described below is any one or two kinds of and mixes or two or more mixing; The photosensitizers preferable range is 0.5～0.8 part, and concrete photosensitizers comprises as follows:
