Abstract
A highly-filled fully-biodegradable packaging material is obtained by mixing and extruding the following components on a weight basis: 70-90 parts of fillers, 10-30 parts of biodegradable polymer, 0.5-3 parts of coupling agents, and 2-5 parts of plasticizers. The fillers are dried at 100-200 DEG C to obtain a water content of not more than 0.5%; the coupling agent is mixed and stirred with the dried fillers according to a certain ratio in a high-speed mixing machine; the biodegradable polymer and the plasticizer are added proportionally, and well mixed; the mixture is extruded and granulated in an extruder to obtain a material for packaging; and the a material for packaging can be processed into various packaging materials by blow molding, injection molding, molding, and the like. When the packaging plastic of the invention becomes waste, the material can degrade into carbon dioxide, water and inorganic mineral in natural environment, which solves the problem of white pollution, and the material is a green and environment-friendly packaging material; the content of the inorganic filler is high, and reaches above 70%, which greatly decreases the production cost. The production cost is low; the preparation process is simple; and the economic practicality is strong.
Description
Technical field
The present invention relates to wrapping material, particularly relating to a kind of is the complete biodegradable wrapping material of major ingredient with the inorganic powder.
Background technology
Along with the development of human economy and society, the demand of Plastic Packaging Materials grows with each passing day, the speed increment with annual 5%.The common plastics variety as wrapping material has polyethylene, polypropylene, polyvinyl chloride etc., follow a large amount of uses of plastics two serious problems to occur: the raw material overwhelming majority of plastics industry is from oil on the one hand, along with the oil and natural gas resource reduces even exhaustion gradually, plastics industry will be faced with the situation of shortage of raw materials; On the other hand, because plastics are not easy to decompose and are recycled into " white pollution " in order to be seen everywhere, destroyed ecotope.Therefore, increasing people and country advocate the development and application complete biodegradable plastics.Complete biodegradable plastics is under nature or specified conditions (as compost, anaerobic digestion or water-based nutrient solution), degrade by microorganism (as red bacterium, mould and the marine alga etc.) effect that nature exists, and can be degraded to carbonic acid gas fully or/and methane, water etc. are environment underload material.In addition, the main raw material of some biodegradable plastic can substitute as replenishing of non-renewable petroleum resources limited, exhaustion day by day from obtain the regenerated agricultural resource every year.The biodegradable plastic of having developed at present has tens kinds, wherein the fully biodegradable plastics of suitability for industrialized production mainly comprise poly(lactic acid) (PLA), poly butylene succinate (PBS), polyhydroxyalkanoate (PHA), poly butyric ester (PHB), polycaprolactone (PCL) etc., have a very wide range of applications in fields such as medical material, agricultural fishery, packing business, sanitary products, existing numerous industrialized launch products are as compost bag, disposable tableware, agricultural mulching, packing film, fishing gear, diaper, operation bounding wire etc.Aliphatic polyester/starch powder composite material of fully biodegradable and preparation method thereof is disclosed as patent CN1450120A, mainly by dioxy pimelinketone polymkeric substance, starch and expanding material are formed.Patent CN1491986A has invented aliphatic polyester composite material of complete biodegradable and preparation method thereof.In the aliphatic polyester of complete biodegradable, add cheap mineral filler lime carbonate and fill, can adopt extrude, different goods in the multiple working method processing such as molding, injection moulding, spinning.Wherein the content of lime carbonate is 25%-50%.Reach more than 70% if further improve the content of lime carbonate, or even 90%, the fully biodegradable wrapping material that exploitation height is truly filled, fewer to this relevant report, the related packaging goods rarely have sale on the market.
Summary of the invention
The technical problem to be solved in the present invention, provide the nontoxic environmentally friendly packing material of a kind of environment-friendly type, solve the problem that the Traditional Packing material can not be degraded environment is polluted, the mineral filler of these wrapping material can reach the 70-90% of weight, the complete biodegradable wrapping material that the height that its cost significantly descends is filled.
The technical scheme that adopts is:
A kind of complete biodegradable wrapping material of high filling are mixed to extrude forming by following component, meter being respectively by weight:
Inorganic filler 70-90
Biological degradation polyalcohol 10-30
Coupling agent 0.5-3
Softening agent 2-5
Described weighting material mainly is meant mineral filler, it is characterized in that described inorganic filler is cheap inorganic powder, include but are not limited to one or more mixtures in lime carbonate, magnesiumcarbonate, calcium sulfate, sal epsom, flyash, clay, talcum powder, mica powder, kaolin, titanium dioxide, chalk or the magnesia powder, especially the preferable separation particle diameter is less than 800 purpose inorganic powders.
Described biological degradation polyalcohol refers to can be resolved into fully by microbial process the biological degradation plastics of water and carbonic acid gas in environment, include but are not limited to one or more mixtures in poly butylene succinate, poly(lactic acid), poly-glycollide, polycaprolactone, the Biopol GO 4.
Described coupling agent is to be used to improve the consistency of adding between inorganic filler and the biological degradation plastics, and including but are not limited to silicon is that coupling agent, titanium are that coupling agent, aluminium are one or more mixtures in coupling agent or the aluminium titanium composite coupler.
Described softening agent is the auxiliary agent that improves whole system toughness and workability, is preferably polyalcohols, citric acid ester type and wax class mixture.Especially one or more mixtures in preferred ethylene glycol, glycerol, sorbyl alcohol, tributyl citrate (TBC), trioctyl lemon acid (TOC), tributyl acetylcitrate (ATBC), acetyl tributyl citrate three monooctyl esters (ATOC), methylene toxilic acid laurate, stearic acid, the calcium stearate.
Above-mentioned height is filled the preparation method of complete biodegradable wrapping material, comprises the steps:
Step 1: guarantee water content≤0.5% of inorganic filler, inorganic filler drying under 60-150 ℃ of temperature is reached as not reaching then;
Step 2: the weighting material and the coupling agent of step 1 are stirred heat-activated in high mixer;
Step 3: step 2 activatory weighting material and biological degradation polyalcohol, softening agent are mixed;
Step 4: with mixture, the granulation of step 3.
The high fully biodegradable wrapping material of filling of the present invention adopt conventional melt-mixing method and equipment to be prepared, earlier with weighting material 100-130 ℃ dry 2-4 hour, to remove moisture; After thorough mixing stirs in homogenizer according to certain proportioning and dried lime carbonate with coupling agent then, the lime carbonate, biodegradable polymers and the softening agent that are mixed are mixed in proportion extruding pelletization in forcing machine, make the high fully biodegradable packing materials of filling.According to the goods requirement, these wrapping material can be carried out processing modes such as blowing, injection moulding, mold pressing and be processed into various wrapping material.
Useful technique effect of the present invention is: the high fully biodegradable plastics of filling of the present invention are after use, can in physical environment, dissolve and be fragment or powder, and further be degraded to carbonic acid gas and water, and inorganic mineral, having solved the problem of " white pollution ", is the wrapping material of real environmental protection.And the content of mineral filler is very high in this material, reach more than 70%, greatly the reduction of amplitude production cost.Production cost is low, and preparation technology is simple, and economic and practical is strong.
