Abstract

The present invention discloses a method for preparing soluble disposable sanitary tableware. Water, a modifying agent, a plasticizing agent, a softening agent, a swelling agent and fluorocarbon are added to plant starch in a proportion to form a compound, which comprises the steps that the modifying agent and the water are added to the plant starch in a proportion to evenly mix according to certain temperature and time control in a pre-reaction tank; then, material match is carried out, and the plasticizing agent, the softening agent and the swelling agent are respectively added to the plant starch for evenly agitation and swelling forming; tableware is formed by swelling for certain temperature and time, and then heat curing shaping is carried out according to certain temperature and time. The present invention has the advantages of convenient technology, simple and available method, sanitation, no toxicity, no pollution, good water resistance, good oil resistance, good heat resistance and easy degradation and is suitable for industrial production.

Description

The compounding method of solvable disposable tableware
The present invention relates to a kind of compounding method of producing solvable disposable hygienic tableware with plant amylum.
Disposable hygienic tableware in the market is difficult for handling, and is difficult for reclaiming, and brings serious pollution to natural environment.Address this problem the three kinds of methods that mainly contain: a kind of is to produce disposable hygienic tableware with degradative plastics, it is that employing starch and plastics are raw material, the two mixes coupling and makes, wherein the starch component is no more than 60%, starch itself can be degraded in natural environment, but plastic composition is difficult for degraded, can only be present in the soil with the chip form.Although this product has delayed the process of environmental pollution, strictness is said, still environment has been caused pollution, because after the plastics chip is piled up in soil and is increased, can destroy the fertility of soil, this product can clean simultaneously, existing and reuse, is not disposable dinner set; Another kind is the string disposable hygienic tableware, as paper table ware, compares with the degradative plastics dinner set, papery dinner set physical and chemical index and sanitary index are good, can not clean, can not reuse, natural degradation or recovery are as paper making raw material at short notice.But the production cost of papery dinner set is higher, is higher than the degradative plastics dinner set; Another is biodegradable amyloid composition tableware, it is made up of starch, polyethylene, ethylene-acrylic acid copolymer, polyvinyl alcohol, ethylene-vinyl acetate copolymer, calcium stearate, polyalcohol, urea, alkali, surfactant etc., technology is complicated, the production cost height.
The compounding method that the purpose of this invention is to provide a kind of solvable disposable tableware adds chemical assistant in plant amylum, technology is easy, health, nontoxic, pollution-free, and cost is low, and tableware use back is discarded, meets water and makes moist dissolving soon.
For achieving the above object, the present invention by the following technical solutions:
The employing plant amylum is a primary raw material, adds entry, modifier, plasticizer, softening agent, swelling agent, fluorocarbon in plant amylum in proportion.The steps include: 1, in plant amylum, add modifier and water in proportion; 2, in the pre-reaction jar, control, mix by uniform temperature and time; 3, batching adds plasticizer, softening agent, swelling agent by a certain percentage respectively, after stirring, starch is extruded continuously; 4, expanded molding is sent into the starch of extruding in all kinds of moulds of expanded molding, through the expanded tableware that becomes all kinds of shapes of uniform temperature and time; 5, surface treatment behind the product stripping, is carried out heat cure typing, the sterile-processed again finished product that is with fluorocarbon by a certain percentage.
The present invention compared with prior art has the following advantages and effect:
Technology is easy, easy to implement the method, aboundresources, cheap, production process do not have " three wastes ", and be free from environmental pollution, can produce the disposable tableware of all size, health, nontoxic meets the food hygiene requirement, and product has certain intensity, water-fast, oil resistant, heat resistance good, be easy to degraded, can make fertilizer after the degraded, capable of using as feed, be suitable for suitability for industrialized production.
Embodiment:
Adopt plant amylum 70-90%, in starch, add the water of 6-15% and the starch modifying agent of 0.6-2%, in the pre-reaction jar, mix and stir, reaction is 50-120 minute under 80-120 ℃ of temperature, after finishing, reaction adds starch plasticizer 0.8-5% respectively, softening agent 0.2-2%, swelling agent 1.2-3%, a kind of material of each adding, stirred 5-15 minute, after reinforced the finishing, starch is extruded continuously, send in all kinds of moulds of expanded molding, mold shape can be made into bowl, box, dish, shapes such as chopsticks, mould up and down between the gap even, the starch material of extruding in mould through 90-150 ℃ temperature, 5-15 in second expanded molding be the tableware of mold shape, behind the product stripping, product is carried out surperficial spray treatment, spray paint is the starch based water and oil repellent agent, with fluorocarbon 1.2-3% spraying, the product after the spraying is through the hot-die solidifying and setting.Temperature is controlled at 60-120 ℃, time and is controlled at 5-15 second, the sterile-processed again finished product that is.
