Abstract
The present invention relates to a biologically degradable disposable meal box which is formed by compounding chief ingredients, such as starch, plant fiber, lining paper, etc. After fully kneaded, gelatinized starch, plant fiber, a waterproof agent, a demoulding agent, etc. and the lining paper are formed in a compression molding mode and dried, and thus, the meal box is obtained. The present invention can be completely degraded biologically. After the present invention is discarded, the environment can not be polluted. Thus, the present invention can be used for replacing various plastic meal boxes which result in white pollution.
Description
The invention belongs to the packing technique field, particularly the food container of manufacturing by Biodegradable material.
Along with the cry of international and domestic control " white pollution " grows to even greater heights and progressively the implementing of prophylactico-therapeutic measures, the disposable plastic tableware steps down from the stage of history just successively.Press for the substitute products that to degrade for biology on the market.At present, existing paper tableware and moulded pulp set for dining have captured a part of market; But because its manufacturing cost is too high, its price is higher than original plastic tableware far away eventually, is difficult to be difficult to the substituted for plastic tableware and go to recover the lost territory, market for consumer institute generally accepts.Also there are many knowledgeable people to attempt to seek more cheap material in recent years and make disposable tableware, as: Chinese patent CN1061006, CN1082858 etc. have the many patents and the report of product abroad especially.In these patents or the product, have really and manyly draw materials very cheaply, but cost of manufacture is higher, or because of difficult forming, or because of yield rate is too low, still fails to form effectively commercialization production so far.Particularly to make more welcome on the market side's lunch box, suitable technology difficulty is arranged, be difficult to accomplish economy, be suitable for.
The object of the present invention is to provide a kind of disposable lunch-box and manufacture method thereof of biodegradable and lower cost.
Biological degradable disposable lunch-box of the present invention is to be formed through composite coining by main materials such as starch, string and lining paper and auxiliary material such as waterproofing agent, releasing agent.Its preparation method is:
1, the starch of gelatinization is mixed with main ingredient such as stearic acid, triethanolamine, paraffin, string, talcum powder and an amount of water, through fully kneading to make pug.
2, the cutlery box mold heated that will make of metal material.Die is heated to 150-250 ℃, preferably 190-220 ℃; Punch is heated to 110-210 ℃, preferably 150-180 ℃.Get an amount of above-mentioned pug (about every milliliter of die cavity holds 0.3 gram left and right sides solid part) and place die, then, cover sizeable scraps of paper on the whole, lock behind the matched moulds, depanning promptly in back to be dried (needing 1-3 minute approximately).
3, if interior lining paper in advance without water-proofing treatment, also need apply one deck water-repellent paint.
The proportioning of various compositions is as follows in the pug:
Title weight portion scope optimum weight part scope
Starch 100 100
String 0-250 80-200
Stearic acid 3-20 5-10
Triethanolamine 1-8 2-3
Paraffin 5-50 10-20
Talcum powder 20-200 60-120
Also need add total solid branch weight 1.4-3 water doubly and call system.
Starch in the above-mentioned prescription also can partly or entirely substitute with flour, and string can be the fibrous material of paper pulp, paper powder or some the herbaceous plant cane through suitably going the lignin processing.If in pug, add the alum and the sodium acid carbonate of a little (generally not being higher than 2%), can be to material in the forming process mobile favourable.
The grammes per square metre of lining paper generally must not be lower than 20g/m
2
This invention passes through to change the mould of different types, but except that the producer lunch box, also can produce goods such as bowl, dish, dish, cup.
Embodiment:
1, gets 100 parts of starch, 750 parts in water, 9 parts of stearic acid, 2 parts of triethanolamines, 15 parts in paraffin, heating under constantly stirring.Insulation is 10-20 minute when temperature rises to 80-95 ℃, makes abundant gelatinization.After stopping heating, add 180 parts of yellow plate paper powder and 100 parts of talcum powder, knead evenly, get pug, standby.
To 210 ℃ of dies, 160 ℃ of punch are got an amount of above-mentioned pug and are dropped into die, cover the common blank sheet of paper of last layer then, the matched moulds locking with mold heated.Open after 2 minutes and touch, take out product promptly.
2, get 100 parts of starch, 500 parts in water, 10 parts of stearic acid, 2 parts of triethanolamines, 10 parts in paraffin, 110 parts of 10% aluminum potassium sulfate solutions, heating under constantly stirring, insulation is 10-20 minute when being warming up to 80-95 ℃, makes abundant gelatinization, after stopping to heat, mix 180 parts of yellow plate paper powder, the sodium bicarbonate solution of 100 parts of talcum powder and 120 part 10% is kneaded evenly, makes pug.
To 220 ℃ of dies, 170 ℃ of punch are got an amount of pug and are dropped into die, are covered with the common blank sheet of paper of one deck again, close and touch locking with mold heated.Open after about one minute and touch, take out product promptly.
3, get 100 parts of starch, 400 parts in water, 5 parts of stearic acid, 1 part of triethanolamine, 10 parts in paraffin, 80 parts of 10% aluminum potassium sulfate solutions, heating under constantly stirring, insulation is 10-20 minute when being warming up to 80-95 ℃, make abundant gelatinization, stop heating after, mix the sodium bicarbonate solution of 200 parts of talcum powder and 30 part 25%, knead evenly, make pug.
To 220 ℃ of dies, 180 ℃ of punch are got an amount of pug and are dropped into die, are covered with the common blank sheet of paper of one deck again, the matched moulds locking with mold heated.Die sinking after about one minute is taken out product promptly.
