Abstract
An easily degradable disposable dining set or package of food or goods is prepared from starch (70-90 wt.%), plant fibre (3-15 wt.%), plant oil (3-5 wt.%), activated calcium (3-12 wt.%), puffing agent (0.3-1.5 wt.%) and water through stirring, hot die pressing at 180-200 deg.C and 20-30 MPa, and applying water-proof colloid onto surface. Its advantages are no toxicity, odour and pollution, easy degradation, high strength, low cost and reclaiming it as feed or fertilizer.
Description
The present invention relates to a kind of is easily degradable disposable tableware, food and the article packing products that main raw material is made with starch.
Because now the polystyrene foamed that uses on the market (being called for short EPS) fast food lunch-box is producing a large amount of high carcinogenic substances and causing serious white pollution during high temperature more than 65 ℃, will be in the near future be prohibited and produce and use by country.Be to solve substituting of EPS tableware, domestic existing a lot of scientific research departments and manufacturer have studied various substitute products in all its bearings, and beginning of having produced in batches and come into the market in some place.But according to investigation, the substitute products of most of manufacturer production adopt paper fiber or paper pulp to make, and needing a large amount of timber is raw material, equals to destroy indirectly ecotope; It is that main raw material is made with vegetable fibre such as crop stalk fiber that the substitute products of some manufacturer production are also arranged, existence can not be satisfied whiteness and require, has peculiar smell, its quality and the unacceptable shortcoming of price human consumer, study according to relevant department, what finally can substitute EPS tableware and goods has only starch based the most suitable, producer of at present domestic existing a few family test-manufactures, but handles the cost height because of all not carrying out expandability.
It is at above-mentioned weak point that order of the present invention has, and it is oyster white that a kind of outward appearance is provided, the packing articles of nontoxic, tasteless, pollution-free, easy degraded, bear a heavy burden strong, that cost is low easily degradable disposable tableware, food and article.
It is such that the object of the invention realizes: adopting weight ratio is 70～90% starch, 3～15% vegetable fibre, 3～5% vegetables oil, be aided with 3～12% Calcium of intensifiens and 0.3～1.5% swelling agent again, after adding an amount of water stirring, once hot-forming, its surface-coated waterproof glue after the moulding.
Furtherizationization scheme of the present invention is: the weight percent of raw material is 70～75% starch, 12～15% vegetable fibre, 4% vegetables oil, 10～12% Calcium of intensifiens and 1.0～1.2% swelling agent.
The present invention has following positively effect:
1, the outward appearance of tableware is an oyster white, have nontoxic, tasteless, pollution-free, easy degraded, the advantage such as strong of bearing a heavy burden, the test of bearing a heavy burden meets national standard fully, outdoor wind, drench with rain, Exposure to Sunlight dissolving in 10 days, in indoor water 5 days the dissolving, with in 90 ℃ ± 5 ℃ the hot water half an hour ne-leakage;
2, because this tableware adopts natural material, can collect as the feed of livestock or poultry or in the rubbish the inside on ground with good conditionsi can become organic fertilizer after degraded;
3, add the WTA swelling agent, the starch main body is foamed in the course of processing, this way can make the starting material consumption of tableware reduce 25～35%.Processing makes the mobile performance of starting material improve greatly aborning owing to foam, and make product subsurface bright and clean, closely knit, and the steam that material institute water content is produced is taken away fast by foamed gas.Thereby reach processing temperature can with than not adding 30～50 ℃ of the downward modulations that foaming handles, reduce the consumption of energy.
4, because of adopting the WTA swelling agent, starch can carry out modification to be handled, and without tensio-active agent, sanitas and other various chemical assistants, reaches the purpose of simplifying production technique, production cost reduction.
The present invention is further illustrated below in conjunction with embodiment.
