Abstract
The present invention relates to a starch-based biodegradable material and a production method of disposable tableware prepared from the material. The starch-based biodegradable material comprises the following production raw materials: starch, persulfate, hexametaphosphate, dibasic alcohol, titanium dioxide, calcium carbonate, talcum powder, titanate, polyvinyl wax, polybasic acid, polypropylene, high-density polyethylene, linear low-density polyethylene, etc. Firstly, 50 to 70% of starch is added into a high speed mixing stirrer during preparation; then, auxiliary materials are sequentially added into the high speed mixing stirrer according to different sequences; and finally, the materials are discharged into a material mixing tank for use after agitation, starch modification and mixing. The production method has the advantages of simple technology, fewer procedure, high efficiency and favorable material performance. The produced starch-based biodegradable material and tableware thereof have high degrading speed in the microorganism environment and are degraded into soil friendly substance in three months to one year. Besides, 'white pollution ' can not be caused. Therefore, the starch-based biodegradable material is the ideal substitute for replacing disposable nondegradable packing materials prepared from polystyrene and polyethylene.
Description
Invention field
The invention belongs to the prescription and the production technique thereof of starch-base biodegradation disposable tableware, particularly a kind of starch-base biodegradation material and disposable food or beverage container production method thereof.
Background technology
The fire light weight of food and drink tool of disposable plastic, advantage such as price is low, and is easy to use becomes the main product of disposable food or beverage container, many decades in vogue.Simultaneously easily, caused unprecedented " white pollution " disaster.Non-renewable petroleum resources, having only the disposable product of several minutes use value with high being processed into is significant wastage to Nonrenewable resources, has destroyed implementing of the strategy of sustainable development.In order to satisfy the service requirements of people to disposable food or beverage container, eliminate the disaster of " white pollution " again, a large amount of simultaneously starch that use reproducible agricultural year corn help Sustainable development, and we work out the high Biodegradable starch food and drink tool of starch content.Through using and testing identity, this product not only has the various performances of plastics, and the biological degradation that is highly advantageous to of a large amount of starch is desirable substitute products of administering the plastic tubleware and drinking ware of " white pollution ".
Summary of the invention
The purpose of this invention is to provide that a kind of to be used for the production biological degradation effective, the composition of the Biodegradable starch food and drink tool of the high-content of starch that mechanical property is good, and its production method.
Composition of the present invention comprises following component:
Starch 50-70wt%
Persulphate 0.5-1.5wt%

High density poly propylene 8-16wt%
Linear low density polyethylene 1-5wt%
Wherein with regard to price and availability, starch is preferably W-Gum.Other starch starch though be not preferred as tapioca (flour), yam starch, sweet potato starch etc., also can be used.
Persulphate for example can be Sodium Persulfate, ammonium persulphate, Potassium Persulphate etc.
Hexametaphosphate for example can be Sodium hexametaphosphate 99, hexa metaphosphoric acid potassium etc.
Dibasic alcohol is selected from propylene glycol, ethylene glycol, butyleneglycol, hexylene glycol, ethohexadiol etc.
Polyprotonic acid is selected from one or more in toxilic acid, Succinic Acid, propanedioic acid, hexanodioic acid, pimelic acid, fumaric acid, methylene-succinic acid, phthalic acid, the stearic acid etc., preferentially is selected from the mixture of stearic acid or stearic acid and other polyprotonic acid.
Titanic acid ester for example is selected from butyl (tetra) titanate, the own ester of metatitanic acid etc.
The production method of the Biodegradable starch food and drink tool of high-content of starch of the present invention is characterised in that successively and may further comprise the steps:
1, the starch with 50-70wt% adds the high-speed mixing stirrer, then through the persulphate of 0.5-1.5wt%, the hexametaphosphate of 0.5-1.5wt%, the dibasic alcohol of 0.5-1.5wt%, the titanium dioxide of 0.1-0.9wt%, the lime carbonate of 2-5wt%, the talcum powder of 0.5-1.5wt%, the titanic acid ester of 0.5-1.5wt%, the polyethylene wax of 0.5-1.5wt%, the polyprotonic acid of 0.5-1.5wt% are added the high-speed mixing stirrer successively, at 900 rev/mins, stirring under 70-90 ℃ the condition, mixing, modification 20 minutes.
2, the linear low density polyethylene of the high density polyethylene(HDPE) of the polypropylene of 5-25wt%, 8-16wt%, 1-5wt% is added in the mixture in the high-speed mixing stirrer, under 400 rev/mins, 130 ℃ condition, mixed 5 minutes, discharging is interior stand-by to mixing tank for coating colors.
3, the material that will mix, in the loading hopper of the disposal molding main frame of adding diameter 135mm, the screw diameter 135mm of molding main-machine, screw rod major diameter 22: 1,90 rev/mins of screw speeds, the temperature of machine barrel is first section 150 ℃, second section 160 ℃, the 3rd section 170 ℃, the 4th section 175 ℃, compound is processed to the starch-resin melts of thermoplasticity macroscopic view homogeneous under these conditions.
4, the starch-resin melts of homogeneous is put into the disposal molding machine by the outlet molding of main frame, is processed into the molded tableware of the definite shape of 0.2-2mm under 185 ℃, and cuts into the commodity of finished product through test package, and warehouse-in is waited to sell.
Above-mentioned once through moulding technology is directly made the food and drink tool by raw material, does not need the moulding of first granulation reheat, work simplification.Though composition of the present invention also can be according to common method, as molding, machine-shaping such as extrude, not preferred.
Advantage of the present invention is: directly use starch to be raw material, need not to carry out the pre-treatment of raw material, technology is simple, and operation is few, and the worker-house area is little, and is artificial few; Adopt disposable machine-shaping, facility investment is few, save energy, manual operation is few in the production process, directly is processed into finished product, sanitation and hygiene, pollution-free in the course of processing, contain a large amount of starch in the product, after use was discarded, biological degradation was good fertilizer to plant-growth, or as the nutrient chemical of edible mushrooms, also can be used as fuel, be embedded in the rubbish, biodegradable one-tenth innoxious substance.
