Abstract
The present invention relates to disposable tableware and a manufacturing method thereof. The disposable tableware is manufactured by mixing crop husks or stalk powders with polyamide hot melt adhesive or nylon hot melt adhesive or polyester hot melt adhesive by a hot pressing technology in one step without the processes of baking and surface film material spraying. The formula of the present invention is simple, and the technology is convenient. The product of the present invention has the advantages of natural color, heavy weight, rigid structure, water resistance, heat resistance, corrosion resistance, no toxicity, no pollution and easy degradation, and is a new environmental protection product.
Description
What the present invention relates to is the meal apparatus, especially a kind of free of contamination disposable table ware and manufacture method thereof.
The existing disposable table ware made from Poly Foam and plastics exists: resource one, consumes petroleum; Two, the freon of foaming usefulness destroys the smelly layer of atmosphere; Three, be embedded in without putrefaction in 200 years in the soil, cause serious defectives such as white pollution.Part adopts paper products or starch based goods to replace at present, and paper products will consume a large amount of bamboo wood, destroy green resource, and the water pollution that causes during paper production can form public hazards; The starch based goods will consume a large amount of grain, and easily mouldy, so technical problem and the environmental protection problem that is worth the merchant true all arranged.Plasticizer such as powder such as disclosed a kind of employing cereal shell of Chinese patent CN93100751.8 or bar and gelatin and hydro-thermal are molded, and be coated with made membrane on the surface and the disposable tableware made, scientifically utilized the discarded object after the processing of farm products, make it to become a kind of new material, new product, can replace Poly Foam and plastic products and paper products, can reduce effectively or finally elimination " white pollution ".The not only easily degraded of tableware of adopting this raw material to make, and can be used as feed after reclaiming pulverizing, be the comprehensive utilization of resource, be a kind of positive manner that forms optimum ecological circulation in the Nature biosphere.But the manufacturing process of the described disposable tableware of this patent is complicated, needs baking, and the tableware surface after the moulding also needs spray-coated film, so the cost height, is difficult to promote the use of.
The objective of the invention is the deficiency at above-mentioned disposable tableware existence, provide a kind of manufacturing process simple, cost is low, and hard disposable table ware and the manufacture method thereof of structure.
The technical solution used in the present invention is: the powder that adopts crop shell or bar and polyamide hot or nylon hot-melt adhesive or polyester PUR mix afterwards to suppress and form.Its manufacture method is: above-mentioned raw materials is ground into powder more than 60 orders respectively, mixes in proportion to stir and tremble evenly; Mixed raw material adds in the matrix cavity of mold tool by making the required consumption of meal apparatus, and the mould temperature control is adopted 20～60kg/cm at 105～190 ℃
2Pressure the punch of mould is exerted pressure, pressurize drive to be pressed after 10～40 seconds, promptly made meal apparatus finished product.
It is that primary raw material is made the disposable tableware complex process that the present invention has overcome in the prior art with crop shell bar, defect of high cost, its prescription is simple, technology is easy, a compression moulding need not toasted, and the surface need not spray coating materials, can reach water-fast, the effect of mashed, no mould, pollution-free, the easy degraded of anti-ripe, corrosion resistant in the same old way.The present invention has utilized the discarded object after the processing of farm products scientifically and rationally, and raw material sources are immortality every year, and extensively doldrums are regeneration comprehensive utilizations of a kind of resource.Advantages such as it is natural that meal apparatus of the present invention also has the finished product color and luster, and matter is heavy, and structure is hard are a kind of brand-new environment-friendly products.
Embodiment:
1, pulverizes: crop shell or bar are dried, be cut into the chip (mainly referring to crop straw) about 3mm, send in the atomizer, be ground into the above powder of 60 orders;
2, stir: the powder 95% of getting crop shell or bar places mixer to stir into mixed material with polyamide hot DH-6-1 dry powder 5%.
3, feed: take by weighing raw material to the material mouth according to making meal apparatus institute expense;
4, mold heated: the punch heating-up temperature is 130 ℃, and the die heating-up temperature is 120 ℃:
5, moulding: open the dosing mouth, the raw material that mixes is inserted in the die, start pressue device punch is exerted pressure, pressure is 40kg/cm
2, pressurize release after 20 seconds, after male and female mold leaves 10cm, the meal apparatus finished product that can obtain to make.
Claims (5)
