Abstract
The present invention relates to full-degradation tableware and a packaging material made of plant fibers, which is composed of plant straw powder, a nontoxic binding agent and an edible additive agent and accounts for weight percentage by the following proportion: 50 to 95 of the plant straw powder, 0.5 to 30 of the nontoxic binding agent and 0.5 to 30 of the edible additive agent. An anti-seepage film is dipped and fixed on the surface of the present invention, and the manufacturing method of the present invention comprises the steps that impurities of the straw are removed, and the straw is crushed to 20 to 80 meshes; then, the binding agent, the additive agent and water are added to the straw for even mixture and then are added to a mould for pressurization and warming; a pressure is from 50 to 1500 kg/cm, a temperature is from 50 to 230 DEG C, and curing time is from 5 seconds to 15 minutes; after being demoulded, the mixture is dipped and coated with the anti-seepage film, and then drying, disinfection and packaging are carried out. The product of the present invention can be completely and naturally degraded for 48 days more or less, can be used as fodder after being crushed and can be used as fertilizer after being degraded. Moreover, the present invention has the advantages of low cost and no three-waste pollution during production and can be made into disposable tableware and a packaging material.
Description
The present invention relates to a kind of tableware that can high-fallly separate and packing material and manufacturing forming technique thereof.
Existing disposable foaming plastic tableware with after can not natural degradation, burning discharges harmful gas again, and the residue after burning is grease, also is difficult for decomposing.If reclaiming, its cost are the twices of tableware cost, especially reclaim difficulty.This kind disposable tableware has caused the white pollution and the public hazards of utmost point refractory reason to society.Recently people develop the paper mould disposable tableware again, and this kind tableware is main raw material with the wood pulp, and it can cause the original timber resources that just lacks very much further exhausted, and work in-process will give off a large amount of harmful waste liquids, cause environmental pollution.With its degradation time of back is three months, and its cost is also higher, can not be utilized once more.
The objective of the invention is to develop a kind of degradable tableware and packing material of manufacturing by string, this tableware and packing material cost are low, can be as disposable use, and degradation time is short, especially the raw material of its utilization is easy to get, and abundant, moreover this tableware and packing material with after can also be used as feed and fertilizer.Its forming technique is provided simultaneously, and this manufacture method is answered three-waste free pollution.
Tableware of the present invention is made up of plant stalk powder end, nonpoisonous adhesive, edible compound, they respectively account for following ratio by weight percentage: plant stalk powder end 50-90, nonpoisonous adhesive 0.5-30, edible compound 0.5-30, also soak intrinsic nontoxic antiseepage film on the surface of tableware, the thickness of nontoxic antiseepage film is 0.1-0.5 μ m.The plant stalk powder end is at least by a kind of composition the in cornstalk powder, straw powder, rice husk powder, sorghum rod powder, bean straw powder end, cotton bar powder, the weeds powder.Nonpoisonous adhesive is at least by a kind of composition the in gelatin, gelatine, white lac, charcoal acid calcium, cyclodextrin, calcium stearate, zinc stearate, the thermosol adhesive.Edible compound is at least by a kind of composition the in corn flour, wheat flour, lithopone, zinc oxide, the titanium dioxide.Nontoxic antiseepage film is at least by a kind of composition the in edible resin, solvent, the ethyl cellulose.Packing material of the present invention is made up of plant stalk powder end, nonpoisonous adhesive, edible compound, they respectively account for following ratio by weight percentage: plant stalk powder end 50-90, nonpoisonous adhesive 0.5-30, edible compound 0.5-30, also soak intrinsic nontoxic antiseepage film on the surface of packing material, the thickness of nontoxic antiseepage film is 0.1-0.5 μ m.The plant stalk powder end is at least by a kind of composition the in cornstalk powder, straw powder, rice husk powder, sorghum rod powder, bean straw powder end, cotton bar powder, the weeds powder.Nonpoisonous adhesive is at least by a kind of composition the in gelatin, gelatine, white lac, charcoal acid calcium, cyclodextrin, calcium stearate, zinc stearate, the thermosol adhesive.Edible compound is at least by a kind of composition the in corn flour, wheat flour, lithopone, zinc oxide, the titanium dioxide.Nontoxic antiseepage film is at least by a kind of composition the in edible resin, solvent, the ethyl cellulose.The manufacture method of being manufactured degradable tableware by string is: at first the plant straw removed root, remove mud, pulverize then, the plant stalk powder end is at least by a kind of composition the in cornstalk powder, straw powder, rice husk powder, sorghum rod powder, bean straw powder end, cotton bar powder, the weeds powder.Filter out 20-80 purpose powder, join in the mould stirring after plant stalk powder end, nonpoisonous adhesive, edible compound, the water mixing, nonpoisonous adhesive is at least by a kind of composition the in gelatin, gelatine, white lac, charcoal acid calcium, cyclodextrin, calcium stearate, zinc stearate, the thermosol adhesive.Edible compound is at least by a kind of composition the in corn flour, wheat flour, lithopone, zinc oxide, the titanium dioxide.Give the mould pressurized, heated, pressure is at 15-1500kg/cm
