Abstract
The present invention discloses a biodegradable starch and poly lactic acid composite packaging material and a preparation method thereof, comprising 45 percent-62 percent by mass of starch, 4 percent-12 percent by mass of poly lactic acid, 13 percent-22 percent by mass of plasticizer, and 12 percent-23 percent by mass of filler. The composite material of the invention has a white appearance, is innocuity, has no foreign smell, and is clean. And the invention has a sufficient mechanical strength and temperature resistance to satisfy the using requirement for the packaging of singleservice packing product, and the product is a perfect material to avoid white pollution.
Description
Technical field
The present invention relates to a kind of fecula polylactic acid material and preparation method thereof.
Background technology
Along with the epoch advance, whole world plastics output is more more than 100,000,000 tons/year, wherein 30% is used for packing, brought a large amount of rubbish owing to can not degrade after the short product of this life cycle uses to human habitat, growing " garbage mountain " more and more regarded threat to the ecosystem as for people, cause environmental pollution for a long time, petroleum resources as one of energy reduce day by day simultaneously, Gu and everybody wishes that the wrapping material that have green energy resource also can degrade fully replace the Plastic Packaging Materials that can not degrade.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of biodegradable fecula polylactic acid ' alloy ' packaging material and preparation method thereof, to overcome the above-mentioned defective that prior art exists, and be raw material with the green energy resource resource, separate and must not cause serious white pollution to environment for human survival by the degradative plastics wrapping material.
Biodegradable fecula polylactic acid ' alloy ' packaging material of the present invention, its component and weight percent content comprise:
Starch 45～62%
Poly(lactic acid) 4～12%
Softening agent 13～22%
Weighting agent 12～23%
Said starch comprises a kind of or its mixture in W-Gum, wheat starch, tapioca (flour), sweet potato starch or the other plant starch;
Said poly(lactic acid) is that raw material prepares through bio-transformation by corn, and molecular weight is 250,000～300,000, can adopt the commercially available prod, and the trade mark of producing as U.S. Cargill Inc is the product of 2002D;
Said softening agent is selected from the mixture of sorbyl alcohol, polyvinyl alcohol, mono-glycerides, mono-glycerides and ethylene acrylic acid co polymer or ethene acetic acid alkene copolymer and polycarbonate.
Said weighting agent is selected from talcum powder, lime carbonate, inorganic mineral powder or slag.
The weight percent content of recommending comprises:
Starch 52～60%
Poly(lactic acid) 6～10%
Softening agent 15～18%
Weighting agent 15～20%
The present invention's " alloy " wrapping material, its thickness are 0.25～2.2mm film or φ 3～5 * 3～5mm particle, processing and utilization general-purpose plastics processing as required, and machinery further carries out plastic uptake, blowing, injection moulding, extrusion molding and is processed into various wrapping material.
The preparation method of biodegradable fecula polylactic acid ' alloy ' packaging material of the present invention comprises the steps:
With the blend in mixing roll of above-mentioned raw material, extruder grain in extrusion machine (or compressing tablet) adopts conventional plastic working method to carry out the various wrapping material of machine-shaping then, and blending temperature is 90～120 ℃, and granulation, compressing tablet temperature are 160～250 ℃.
The present invention's " alloy " material has following characteristics:
1. pure white, any surface finish of outward appearance, nontoxic, harmless, free from extraneous odour, sanitation and hygiene, safety
2. main raw material: starch, poly(lactic acid) are natural macromolecular materials, it is the continuous green energy resource in source, after becoming " alloy " with softening agent, weighting agent blend copolymerization, have (+120 ℃ of enough physical strengths and heat resistances,-20 ℃), can satisfy the service requirements of non-returnable container material product packing fully.
3. use the wrapping material pass through, because its starch, poly(lactic acid) content are higher, can degrade under field conditions (factors), biodegradation rate is fast, and starch wherein, poly(lactic acid) and softening agent are broken down into H
2O and CO
2, the inorganic materials in the stopping composition revert to then that soil receives in the large nature, is the comparatively ideal good material of current preventing " white pollution " therefore.
4. production process is not used steam and organic solvent and PS, PVC, PE, PP, and water coolant adopts recycle, does not produce waste water,waste gas and industrial residue, does not cause environmental pollution.
5. production process can realize mechanize, automatization, mass-producing.Main raw material starch, poly(lactic acid) can satisfy the sustainable development requirement for the green energy resource resource, and production cost is relatively low, is easier to marketing, the huge market demand.
