Abstract
The composition of the material for disposable degradable tableware includes: inorganic mineral base material 40-70 wt%, light material 10-30 wt%, reinforcing material 5-15 wt%, adhesive 5-20 wt% and film coating agent 2-5 wt%. The material is easy to degrade and produces no environmental pollution, and the productino process is simple and no "three wastes" produced.
Description
The present invention relates to tableware and manufacture method thereof, relate in particular to disposable degradable tableware and manufacture method thereof.
Existing disposable tableware great majority all are made with expanded plastic, and this tableware light weight, look shallow, cost is low, but do not degrade; Temperature can produce a kind of chemical substance of being Dioxins during greater than 60 ℃, and this chemical substance toxicity is very big, and has serious carcinogenesis.Afterwards, have the people to develop papery disposable tableware, vegetable fibre disposable tableware again, well-known, papermaking need consume a large amount of timber resources, and the product cost height, produces and causes environmental pollution; And the plant fiber tableware color and luster is bad, and product fragility is big, the manufacturing process complexity.
Purpose of the present invention is exactly that a kind of degradable, cost is low, manufacturing process simply, can not cause environmental pollution disposable tableware and manufacture method thereof are provided in order to overcome the weak point that above-mentioned prior art exists.
Purpose of the present invention can realize in the following manner: disposable degradable tableware, and it forms (weight %) by following prescription:
Inorganic mineral base-material 40-70%
Light material 10-30%
Strongthener 5-15%
Binding agent 5-20%
Liniment 2-5%
Described inorganic mineral base-material be selected from clay, polynite, decayed rack, wilkinite, lime carbonate, gypsum, kaolin, silica, potter's clay, the float stone wherein one or more.
Described light material be selected from perlite, glass microballon, porous ceramics ball, the expanded slag wherein one or more.
Described strongthener be selected from cast tow fiber, short cotton fibre, xylon, the paper pulp wherein one or more.
Described binding agent be selected from water glass, methylcellulose gum, dialdehyde starch, alginic acid, the agar wherein one or more.
Described liniment be selected from Vinyl Acetate Copolymer, polyurethane, the polyacrylic acid wherein one or more.
The manufacture method of disposable degradable tableware, it comprises following processing step:
(1). batch mixing: according to the above ratio and add an amount of water in kneader, mixing 20-40 minute under the room temperature with inorganic mineral base-material, light material, strongthener, binding agent, up to the mixture color and luster evenly and till having certain elasticity, the water ratio of final blending material is 10-30% (weight).
(2). moulding: the said mixture material is packed in the charging machine, material dosing is added in the mould, at ambient temperature, rotate mould, the gravity automatic moulding of pattern tool self by shaper by charging machine.
(3). oven dry: the goods after the moulding were dried 5-20 minute under 100-200 ℃ of temperature.
(4). film: the goods after will drying are coated with the waterproof grease proofing liniment of last layer, solidify 2-10 minute under 100-150 ℃ of temperature, promptly get product.
Compared with prior art, the present invention has the following advantages:
1. product color is shallow, and density is little, and intensity is bigger, nontoxic free from extraneous odour.
2. after product uses, can in the following short period of time of natural environmental condition, burst apart, efflorescence, be decomposed into earth's crust integral part, can not pollute environment.
3. raw material sources are abundant, and are cheap.
4. manufacturing process is simple, and energy consumption is low, and production process does not have " three wastes " (waste gas, waste water, waste residue), satisfies environmental requirement.
Below in conjunction with embodiment, the invention will be further described.
