Abstract
The present invention relates to a degradable plastic and plant composite material suitable for manufacturing a disposable fast food box and other packaging boxes and a preparation method thereof. The material is formed by the method that plant powder, calcium sulphate, melamine resin, sodium carboxymethyl cellulose, borax, sodium alginate, sodium stearate, polypropylene resin, hydrogen dioxide diluent solvent and plant fibre are molded at certain temperature after being pulverized, mixed and moistened according to proportion. The degradable plastic and plant composite material has the advantages of convenient manufacture, no production pollution, low cost and favorable degradation performance; furthermore, box products manufactured by the material have the advantages of smooth and beautiful appearance and favorable service performance.
Description
The present invention relates to a kind of degradeable plastic and plant composite material that is suitable for making disposable snack box and other packing box and preparation method thereof.
In recent years, be acknowledged as " white pollution " and be put into forbidding and superseded row by porous plastics made mess-tin and packing articles thereof, so far, developed the multiple material that is used for making the non-returnable container goods, be used for replacing porous plastics, but situation is also desirable not to the utmost.Wherein be the biosynthesizing material product of carbon source with starch, on the high side, be difficult to promote; Also there be comparatively complexity, cost height, the problem that use properties is relatively poor of making in the papery goods; Adopt degradable synthetic fat family lactone, fusing point is low, uses inconvenience; Also record biodegradable plastics article combination material on some documents, adopt treated starch to mix mutually with plastic raw materials as additive, this wrapping material are because the composition of plastics accounts for 65-75% mostly, and its degradation property is relatively poor.
A kind of biodegradable plant fiber packing material (publication number CN1127276A) is disclosed in the Chinese patent communique, it is that main raw material adds mixed systems such as some chemical binders again and forms with vegetable fibre and starch, though have degradation property preferably, but its making processes is comparatively complicated, and there is certain pollution, the box goods fragility of making is bigger, and firmness is poor, thereby is difficult to apply.
The object of the invention is to avoid the weak point of above-mentioned existence and a kind of degredation plastic plant composite type material and preparation method thereof is provided, and this material is not only simple for production, and cost is low, and degradation property is good, and the product of making has good use properties.
The present invention is realized by following scheme: it is by the plant powder, calcium sulfate, melamine resin, Xylo-Mucine, borax, sodium alginate, sodium stearate, acrylic resin, hydrogen peroxide solution, vegetable fibre is formulated, and its proportioning (by weight) is as follows: plant powder 25～35% calcium sulfate 10～15% melamine resins 5～28% Xylo-Mucines 10～20% boraxs 0.5～1% sodium alginate 0.5～1% sodium stearate 0.5～1% acrylic resin 5～28% hydrogen peroxide solutions 10～15% vegetable fibres 10～20%.
In the such scheme, the plant powder can be flour or Semen Maydis powder or sweet potato powder or mealy potato; Vegetable fibre can be Caulis Sacchari sinensis fiber or cotton fiber, and calcium sulfate can substitute with lime carbonate; To be 30% hydrogen peroxide and water by concentration form by 1: 300 volume ratio dilution hydrogen peroxide solution.
Making method of the present invention is: earlier with Xylo-Mucine, borax, sodium alginate, sodium stearate, acrylic resin, vegetable fibre is crushed to more than 80 orders, thereafter with the plant powder, calcium sulfate, melamine resin and the above-mentioned mixing of materials of having pulverized stir, hydrogen peroxide solution is sprayed in the above-mentioned mixture then, damping also mixes, die temperature is adjusted to 110-150 ℃, the mixture of getting respective amount is put into the mould of pressing machine, the pressurization typing, product, product can be different mess-tin or other packing box goods.
The box product of made of the present invention has good shock resistance and toughness, and has the characteristic of anti-boiling water, oil-proofness, acid and alkali-resistance, and use properties is good, meets the service requirements of tableware and packing box fully.The present invention is a major ingredient with plant material and natural mineral matter, a small amount of plastics of remix and other auxiliary composition, wherein vegetable fibre and calcium sulfate are as stopping composition, plant powder, Xylo-Mucine, melamine resin, borax and acrylic resin rise bonding and enhancement, sodium alginate and sodium stearate play a part to preserve moisture and lubricant, and hydrogen peroxide is an oxidation promotor.The present invention is owing to added the plant powder of larger proportion, contain the available carbon source of microorganism, protein and other trace element, be enough to make microorganism on residual body, can breed existence, some material of justacrine progressively resolves into macromolecular material fragment and changes into other food, under the soil fungi effect, fallen, thereby make the present invention have good degradation property, experimental results show that by digestion, the cutlery box that the present invention makes is inserted in the soil, can be degraded in the short period of time.Like this, the disposable tableware of making can solve " white pollution " problem effectively, replaces existing porous plastics tableware and packing box goods thereof.Raw material of the present invention is easy to get, and working method and technology are easy, does not have to produce and pollutes, and the cost of product is lower, and the products obtained therefrom outward appearance is bright and clean attractive in appearance, is particularly suited for making the disposable tableware that is used in a large number.
Fig. 1 is preparation method's of the present invention FB(flow block).
The first embodiment of the present invention is as follows: get material with following proportioning (by weight):
Flour 25% calcium sulfate 10%
Melamine resin 5% Xylo-Mucine 15%
Borax 0.67% sodium alginate 1%
Sodium stearate 1% acrylic resin 15%
Hydrogen peroxide solution 12.33% Caulis Sacchari sinensis fiber 15%.
Xylo-Mucine, borax, sodium alginate, sodium stearate, acrylic resin, vegetable fibre are crushed to 80 orders, thereafter reenter flour, calcium sulfate, melamine resin, mix, hydrogen peroxide solution is sprayed in the said mixture material, damping also mixes, die temperature is adjusted to 150 ℃, gets the above-mentioned compound of mixing well and goes into the mould pressurization, can make product.
The material proportion of second embodiment of the invention (by weight) is:
Flour 28% calcium sulfate 15%
Melamine resin 10% Xylo-Mucine 18%
Borax 0.8% sodium alginate 0.9%
Sodium stearate 0.67% acrylic resin 5%
Hydrogen peroxide solution 10.63% vegetable fibre 11%.
The preparation method is identical with first embodiment, and die temperature is 130 ℃.
