Abstract
The completely-degradable plastics contain no plastic coponents of PP, PE and PS, etc. and comprises the components of poly beta-hydroxy ester, ethylene-like derivative, propylene-like derivative, coen flour, cellulose, calcium carbonate, talcum powder, starch, monooctadecanoic acid, liquid wax, plastisizer, octadecanoic acid, lubricating agent, modified starch and silane coupling agent. Said product can be completely-degraded into organic substances beneficial for environment under the natural condition, and can be made into various plastic products with low strength.
Description
Technical field:
The present invention relates to a kind of novel material that can high-fallly separate, particularly relate to a kind of complete degradable plastic and application thereof.
Technical background:
At present, plastics have become big public hazards of contaminate environment.The expert points out: the main arch-criminal of current China " white pollution " is depleted polyethylene agricultural plastic film, disposable expanded plastic food and drink tool and packing of product filled plastics.
The once special file publishing of country, time limit will be eliminated disposable foaming plastic tableware before the end of the year in 2000, and various places are also taked cut-off, are prohibited the pin measure disposable foamed plastic tableware.But, produce little effect so far.Its major cause is not have a kind of real substitute products that performance is good, price is low.Existing degradable plastics all is to allocate degradable filler and degradation catalyst in resins such as traditional PP, PE, PS, though it can be degraded in shape (fragmentation), but its contained conventional resins can't be degraded, so also there is not real complete degradable plastic at present.
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, a kind of plastic components such as PP, PE, PS that do not contain are provided, degradation property is good, and the low complete degradable plastic of cost, the invention still further relates to the application of this complete degradable plastic.
For achieving the above object, complete degradable plastic of the present invention is the plastics of being made by following raw material:
Poly-β hydroxyl fat vinyl derivative propylene analog derivative
Semen Maydis powder Mierocrystalline cellulose lime carbonate
Talcum powder starch Stearinsaeure
Liquid wax softening agent stearic acid
Lubricant modified starch silane coupling agent
As optimization, the weight proportion of described raw material is:
Poly-β hydroxyl fat 5-45 vinyl derivative 4-20 propylene analog derivative 5-25
Semen Maydis powder 10-30 Mierocrystalline cellulose 2-10 lime carbonate 7-20
Talcum powder 2-10 starch 5-20 Stearinsaeure 0.5-3
Liquid wax 1-3 softening agent 2-6 stearic acid 0.5-3
Lubricant 0.5-3 modified starch 2-20 silane coupling agent 0.5-3
As optimization, the weight proportion of described raw material is:
Poly-β hydroxyl fat 5-30 vinyl derivative 4-15 propylene analog derivative 5-20
Semen Maydis powder 10-25 Mierocrystalline cellulose 2-7 lime carbonate 7-10
Talcum powder 5-10 starch 5-15 Stearinsaeure 0.5-2
Liquid wax 1-2 softening agent 2-5 stearic acid 0.5-2
Lubricant 0.5-2 modified starch 5-15 silane coupling agent 0.5-2
As optimization, the weight proportion of described raw material is:
Poly-β hydroxyl fat 11 vinyl derivatives 8 propylene analog derivatives 14
Semen Maydis powder 20 Mierocrystalline celluloses 5 lime carbonate 7
Talcum powder 7 starch 10 Stearinsaeures 1
Liquid wax 1 softening agent 3 stearic acid 1
Lubricant 1 modified starch 10 silane coupling agents 1
As optimization, described Mierocrystalline cellulose can be the high crop straw powder of cellulose.
The application of complete degradable plastic of the present invention is that described complete degradable plastic is used to make disposable tableware, industry, pharmaceutical sector non-returnable container, life and industrial or agricultural disposable products such as agricultural mulching.
The manufacture method of complete degradable plastic of the present invention is a mixed raw material by weight ratio, and height stirs kneading:
(1) foamed products: the step that also comprises hot-pressing and foaming moulding (physical blowing) and arrangement warehouse-in.
(2) other products comprises that also screw rod extrudes mixing and granulation step;
A, sheet material also comprise: pellet warehouse-in and sheet forming step;
B, plastic uptake product also comprise: it is mixing to grind the sheet secondary, preheating vacuum forming, the step of the cooling forming and the warehouse-in of cutting edge.
C, injecting products also comprise mixing injection moulding, the step of cooling forming and arrangement warehouse-in.
It, is polymerized through mixing as stopping composition with high-fall macromolecular material starch of separating etc.; Select unicity biological degradation polyalcohol, complex biological degradation polymer and biological degradation water-soluble polymers, the blend copolymerization becomes the tackiness agent of gluing filler.This tackiness agent mainly with poly-β hydroxyl fat, vinyl derivative, propylene analog derivative, forms through double base, ternary, quaternary and macromolecular grafted block copolymerization.Polymeric macromolecular material (tackiness agent) forms complete degradable plastic with combinations of materials such as starch again.
Complete degradable plastic under the effect of the humic acids in soil, mould, actinomycetic enzyme and sunlight and natural condition, can decompose in the short period of time under field conditions (factors); Resolve into high molecular hydrolyzate early stage, is the good wetting Agent for Printing Inks of soil, helps improving the organic content of soil again, improves soil property, helps plant-growth, progressively resolves into water and carbonic acid gas then.
Complete degradable plastic goods of the present invention are nontoxic, production process three-waste free pollution, anti-hot water, grease proofing, antiseep, resistance to impact shock, tensile modulus (GB18006.2-1999) all up to standard.Degradation cycle is adjustable.Can replace existing low strength plastics.
Its maximum meaning is to make full use of the corn resources of China's abundant, and the disposable tableware that this complete degradable plastic is made can directly be processed into animal-feed after using, and the movement of animal can be used as the fertilizer of maize planting again; Equally, can directly make humic acid fertilizer, be used further to maize planting as the complete degradable plastic of packing or other purposes; The corn of Sheng Chaning can be used for producing complete degradable plastic again again, thereby constitutes a real harmless green endless chain.And in a single day this circulation is built up and will be reduced the cost of its goods greatly, thereby can thoroughly replace existing conventional plastic wrapping material.
Therefore, complete degradable plastic of the present invention has and can degrade fully, and the low advantage of cost.
