Abstract
The invention relates to a disposable tableware and process for production, wherein the tableware is manufactured from the following raw materials (by weight ratio): starch 35-55 parts, plant fiber 12-20 parts, glycerin monostearate 14-24 parts, stearic acid 13-22 parts and allume 0-3 parts.
Description
Technical field
The present invention relates to a kind of disposable tableware, particularly relate to a kind of energy saving and environment friendly disposal starch dishware and the manufacture method thereof that can high-fallly separate.
Background technology
Along with improving constantly of human living standard, disposable tableware also arises at the historic moment in order to save time, because disposable tableware has health, convenience and adapts to modernized allegro life, and be widely used, existing disposable tableware is divided into following several types, a kind of employing foamed plastic is prepared from, it with low cost, and light weight, but this tableware can not be degraded, can produce the chemical substance with serious carcinogenesis of dioxin when temperature is higher, contaminated environment makes its application be subjected to certain restriction; Another is the disposable tableware that adopts paper material to make, but the disposable tableware that adopts paper material to make need expend a large amount of timber, destroys environment waste resource, and its cost height, the product brittleness is big, and the easy contaminated environment of production process causes the use that is under an embargo of this disposable tableware; Also has a kind of degradable disposable tableware that is, it has solved some problems that above-mentioned two kinds of tablewares exist, but also there is the improved technical problem of following needs in present degradable disponsable tableware: needs add number of chemical additive and adhesive, cause and to degrade fully, cause fundamentally contaminated solution problem of environment, and this disposable tableware exists complex manufacturing, cost height, weight is big, rigidity is not enough, intensity does not reach instructions for use, the long speed of degradation time waits problem slowly.All there is the problem that can not recycle in above-mentioned three kinds of disposable tablewares.
Summary of the invention
The present invention be exactly to provide a kind of in order solving the problems of the technologies described above and can to degrade fully, free from environmental pollution, cost is low, production technology is simple, product rigidity and good energy-saving and environment protecting type onetime meal containers made of starch and the manufacture method thereof of intensity.
In order to solve the problems of the technologies described above, the present invention is achieved in that energy-saving and environment protecting type onetime meal containers made of starch, and it is made up of starch, string, monoglyceride, hard ester acid and alum, and its weight consists of: starch 35-55 part; String 12-20 part; Monoglyceride 14-24 part; Hard ester acid 13-22 part; Alum 0-3 part.
Described energy-saving and environment protecting type onetime meal containers made of starch, the preferred weight of its each component consists of: starch 40-50 part; String 14-18 part; 18-20 parts of monoglycerides; Hard ester acid 15-20 part: alum 0-2 part.
Described starch is cereal starch.
Described string is rice stalk, wheat stalk, maize straw or their mixture.
A kind of manufacture method of described energy-saving and environment protecting type onetime meal containers made of starch, it comprises following processing step:
Getting string by described weight pulverizes, then starch, monoglyceride, hard ester acid, alum and water are added stir mixture, the adding weight of water is 0.5-1.5 times of material, mixture after being mixed is put into mould inner high voltage high-temperature molding become predetermined size and dimension, on the tableware surface, the sealed, sterile drying both got with grease-proof and waterproof agent showering.
The temperature of described sealed, sterile drying is that 110-130 ° of time is 7-10 minute, blast 0.5-0.7kg.
Described high pressure-temperature moulding, its pressure are 7-9KG, and temperature is 190 °-220 °, and molding time is 25-40 second.
Advantage of the present invention and effect are as follows;
Disposable tableware of the present invention is the cereal starch of employing 100% and the product of the synthetic back of pure plant fiber adding assistant high-temperature molding, it can 100% high-fall separating, bury in the ground and can high-fallly separate in 25-28 days, can high-fallly under field conditions (factors) separate in 45 days, its secondary recovery be can be used for feed and changes fertilizer, improved additional value of farm products, product look of the present invention is shallow, two kinds of primary colors and whites are arranged, density is little, and light weight is nonpoisonous and tasteless, product is free from environmental pollution, high temperature resistant and the low temperature of disposable tableware energy of the present invention is at 160 ° high-temperature water, under the brewing of oil 5-6 hour not modification do not spread out soft, modification not under-30 ° the low temperature, its rigidity and intensity are good, but its heat-insulation and heat-preservation can be held to get up to put down.And product cost of the present invention is low, and production technology is simple, and raw material sources are easy to get, and production process is free from environmental pollution.
