Abstract
The biologically degradable disposable tableware is produced with edible corn starch as main material, and through mixing and denaturing with certain amount of plasticizer and stiffing, extrusion, pressing sheet, forming, ultraviolet disinfection and sealed packing. The disposable tableware is safe and hygienic, and has certain mechanical strength and heat resistance. The used tableware may be reused and degraded naturally without environmental pollution.
Description
Affiliated technical field
The present invention relates to a kind of biodegradable disposable tableware and raw material thereof composition, production technique, refer to that specifically a kind of is the biological degradable disposable meal mandarin duck tool of main raw material with starch, with the W-Gum is the raw material of the degradable disponsable food and drink tool of main component, is the production technique of the biological degradable disposable food and drink tool of main raw material with the W-Gum.
Background technology
Along with the quickening of people's rhythm of life, the demand of disposable tableware constantly increases.But,, will become a kind of white pollution of havoc human ecological environment owing to generally use at present the disposable tableware made by the vinylbenzene expanded plastic can not natural degradation.For making disposable tableware and the production process thereof all can compliance with environmental protection requirements, domestic and international many scientific research institutions developing multiple equivalent material and are producing disposable tableware, make the cavings (or straw, straw, bagasse etc.) of tackiness agent as paperboard or paper pulp, with hot melt adhesive.But paperboard or paper pulp need consume a large amount of timber, and pulping process also can produce pollution, and cost is also higher; Adopt hot melt adhesive then to need hot melt adhesive heat fused, the compression moulding of mold heated ability, set time is long, and production efficiency is low, and product appearance is of poor quality.
Summary of the invention
The objective of the invention is to propose the biodegradable disposable food or beverage container product of a kind of corn starch base, in order to what produce this disposable food or beverage container is the Biodegradable material of main component with the W-Gum, and the production technique of this disposable food or beverage container product, with the alternative disposable tableware that can not degrade at present, thereby solve the serious white pollution that disposable tableware causes environment for human survival.
A kind of W-Gum based biodegradable disposable food and drink tool of the present invention, it is characterized in that with edible corn starch be major ingredient, add a certain proportion of softening agent and compound through the modification of high speed batch mixing, extrude, food and drink tool container such as various disposable cups that compressing tablet, moulding make, disposable bowl, disposable snack box, disposable and convenient face packing box, disposable cold drink packing box, disposable bean product packing box.
A kind of W-Gum base biodegradation raw material of producing disposable food or beverage container of the present invention, it is characterized in that being major ingredient mainly by food-grade corn starch, add the softening agent of food grade and compound through the modification of high speed batch mixing, extrude, the master batch of granulation gained, or through the modification of high speed batch mixing, extrude, the sheet material of compressing tablet gained; Its proportioning raw materials is by weight: food-grade corn starch 60-85%, and its recommended amounts is 70-80%, food grade softening agent 10-20%, its recommended amounts is 13-17%, adds an amount of food grade compound again.Described softening agent generally adopts alcohols such as sorbyl alcohol or polyvinyl alcohol, and described compound can adopt talcum powder.
The production technique of a kind of corn starch base bio-degradable expendable dining set of the present invention, its technical process is: batching, the modification of high speed batch mixing, extrude compressing tablet, moulding, disinfection by ultraviolet light and pack, or batching, the modification of high speed batch mixing, extruding pelletization, produce the raw material master batch, and then master batch extruded compressing tablet and forming process, disinfection by ultraviolet light and pack.Now as follows to its technical process division:
● batching: will qualified edible corn starch and softening agent, compound press the proportioning weighing of process stipulation;
● the modification of high speed batch mixing: above-mentioned admixtion is put into the high speed mixing roll carry out the high speed batch mixing, when high speed was mixing, the polarity between moisture in the removal starch and change starch molecule was carried out modification to starch; During batch mixing temperature is controlled in 95-115 ℃ the scope.
● extruding pelletization or compressing tablet: mixed raw material is introduced extruding granulator make compressing tablet behind the raw material master batch, or mixed raw material is directly introduced the sheet material machine be pressed into sheet material; In the process of granulation or compressing tablet, should make material remain on 180-220 ℃ temperature range.
● moulding: above-mentioned sheet material is introduced heat pressing forming machines or vacuum plastic-absorbing machine, make various disposable food or beverage container containers, in moulding process, should avoid the sheet material undue concentration to be heated, and Heating temperature is remained on below 220 ℃.
● disinfection by ultraviolet light, pack: the disposable food or beverage container that makes is carried out disinfection by ultraviolet light, and the disposable food or beverage container after will sterilizing packs.
W-Gum based biodegradable disposable of the present invention food and drink has a lot of characteristics: 1. outward appearance is magnetic white, has higher surface smoothness, nontoxic, harmless, free from extraneous odour, owing to use the raw material of food grade, so sanitation and hygiene; 2. starch is a kind of natural macromolecular material, through with softening agent, compound blend modification by copolymerization after, have enough physical strengths and heat resistance, can satisfy the service requirements of food and drink tool fully; 3. make wrapping material after used food and drink tool waste can foam or be used for mushroom plantation or other fertilizer, fully utilize; 4. owing to its starch content height, biodegradation rate is fast, can degrade under field conditions (factors).After testing, soil buries after 20 days and begins to become fragile at normal temperatures, and 3-4 can all degrade in the month, uses the back in 3-12 month, and under the erosion of natural mould, wherein starch and softening agent become CO
2And H
2O, the compound of inorganic materials was also received by soil originally, was a kind of very ideal substitute that can produce the food and drink tool of " white pollution " at present therefore; 5. do not use steam and organic solvent in the production process, only with water coolant a small amount of and that can be recycled, so do not produce waste water,waste gas and industrial residue, three-waste free pollution is 6. produced and can be realized Fully-mechanized and automatization, the production efficiency height, production cost is relatively low, is easier to marketing.
Embodiment
Now the invention will be further described in conjunction with some embodiment.
Embodiment 1: get food-grade corn starch 62% by weight, and food grade softening agent sorbyl alcohol 18%, food grade compound talcum powder 20% through batching, high speed batch mixing, extruding pelletization, makes the raw material master batch of W-Gum based biodegradable disposable food and drink tool.
