Abstract
A disposable degradable foamed dinnerware is made up of starch, wooden fibre, reinforcing agent, degradation promoter, foaming mother material and water through adding starch to water, heating to 60-90 deg.C, mixing it with reinforcing agent and degradation promoter, reaction for 5-10 min, mixing it with wooden fibres and foaming mother material, quantitative cutting, moulding at 150-180 deg. for 50-80 sec, demoulding, and sterilization. Its advantages are low cost, and high degradation effect.
Description
The invention belongs to food container, particularly a kind of prescription of disposable degradable foamed food or beverage container and manufacture craft.
Solve " white pollution " and public hazards, become a big problem of social concerns, therefore the novel food and drink tool of research and development degraded has become contaminated solution, administer the important topic of environmental protection, begun to forbid to use disposable PS food and drink tool at present in the many cities of China, replaced with degradable food and drink tool, invented degradable food and drink tool in recent years in succession, to solve the considerable damage that former non-degradable food and drink tool causes to environment.Know through investigation, in these inventions, degradable raw material is together bonding with chemical colloid, its defective one is the non-degradable of chemical glue own, therefore its product finally can not all decompose, the 2nd, the bonding finished product of making real and weight is big, the cost height, poor practicability, therefore the effect of degraded also owes perfect.
The object of the present invention is to provide a kind of prescription and manufacture craft of novel disposable degradable foamed food or beverage container, it with sex change after starch replace gluing connecing, have the feature that can all decompose, the filling-foam masterbatch makes product light weight good heat preservation performance, cost is low.
By above-mentioned design, the prescription of the disposable degradable foamed food or beverage container that this programme provides and manufacture craft is characterized in that, the composition of raw materials and the weight percent of this food and drink tool are as follows:
Starch 15-25%, wood fibre 35-40%,
Toughener 3-5%, degradation accelerating agent 2-5%,
Foaming concentrate 30-35% and water, its water and above-mentioned raw materials gross weight ratio are 1.4-1.8: 1.
The manufacture craft of this food and drink tool is followed successively by by the above-mentioned raw materials proportioning:
(1) starch is added in the entry, be heated to 60-90 ℃;
(2) with toughener, stir in the degradation accelerating agent adding (1), reacted 5-10 minute;
(3) adding wood fibre and foaming concentrate are even to (2) middle blending and stirring, become semisolid;
(4) quantitatively cut according to food and drink tool finished product mould quantitative requirement after, put into die forming machine, heat 150-180 ℃, moulding 50-80 demoulding after second;
(5) the finished product internal surface behind the stripping forming carries out showering with degradable macromolecule polyester material;
(6) product carries out sterilization after the showering;
(7) end product packing warehouse-in.
The best modified starch SMA that adopts after the hydroxyl modification is covered in grafting of above-mentioned starch.
Above-mentioned toughener is the plain toughener of edible fibers.
Above-mentioned degradation accelerating agent is the amylases degradation accelerating agent.
Above-mentioned foaming concentrate is inorganic powdery foaming concentrate.
The superiority that adopts this programme to embody: the one, contain main component starch in this composition of raw materials and be starch SMA after the sex change of adopting 99100726.3 patent applications that the inventor proposes, match with other raw material, has good consistency, the chemical glue cementitious product that replaces original technology, very easily under field conditions (factors) easily by the microbial attack degraded; The 2nd, its another composition is the inorganic powdery foaming concentrate of filling, and finished product have small pore, make it in light weight, and good heat preservation performance and color are good; The 3rd, the degradation accelerating agent in this prescription has and impelling degraded to be easy to fast effect, and being discarded in the physical environment 15-20 days can be cleared up by environment; The 4th, carry out leaching coating process in case the soaking into of materials such as hot water, deep fat at the internal surface of finished product; The 5th, adopt prescription of the present invention and technology to can be made into the food and drink tools such as bowl, dish, cup of all size, also can be made into disposable gardening flowerpot, seedling alms bowls etc. are transplanted and are used article; The 6th, it has with low cost, with after promptly abandon, easy to use, degradation effect is remarkable, benefits the nation and the people, and is worth of widely use.
Further specify this programme in conjunction with the embodiments:
Get 20 gram modified starch SMA, add 150 gram water, 3 gram Mierocrystalline cellulose tougheners, 2 gram amylases degradation accelerating agents, fully stir and tremble evenly, be heated to 80 ℃, reacted 10 minutes, it is thick that slurry is white in color, add the sawdust after 40 grams are pulverized then, the wooden robust fibre of wood shavings class, also available straw, straw, corn cob, waste materials such as bagasse replace, and 35 gram inorganic powdered foaming concentrate-carbonate or wilkinites or both blending and stirring that is harmonious are even, become semisolid, quantitatively cut by the finished product requirement, as 50 grams quantitatively, put into die forming machine, heat 160 ℃, moulding 70 seconds, finished product carries out the internal surface showering after the demoulding, sterilization, packing can put goods on the market.
The preproduction of this programme is through evidence: 100 ℃ of hot water of interior Sheng, and 150 ℃ of edible oil immersion tests one hour are non-leakage, indeformable, and scientific experimentation proves, and its degraded easily and can finally all decompose makes it produce very high economic benefit and social benefit.
