Abstract
The invention discloses a kind of heat preservation environment protection food package boxes.Heat preservation environment protection food package box of the invention includes outer box, liner and box cover；The liner is arranged in outer box, on liner along with, along being bonded completely, closed cavity is formed between liner and outer box, box cover covers in outer box in outer box；Settable spontaneous backing in cavity.The heat preservation environment protection food package box that the present invention is prepared has good thermal insulation property, uses under severe cold of winter as the high-end packing box for sending food outside.Moreover, heat preservation environment protection food package box of the invention is detachable lunch box, and outer box may be reused, reduce the use of plastics, have important environment protection significance.
Description
Technical field
The present invention relates to a kind of food box more particularly to a kind of heat preservation environment protection food package box and its production methods.
Background technique
With the quickening of urban life rhythm and the high speed development of internet O2O, more and more persons in many occasions
Take-away is selected to solve the problems, such as food and drink.However, most of at present take out is to install the food of dispatching according to part, it is put into plastic box
Portion, in the consumer's hand for going to be dispensed into each streets and lanes by ground using electric vehicle or motorcycle, especially in winter, by
Relatively more apart from distant dispatching quantity in dispensing, food is easy to cool off in delivery process, and customer is very dissatisfied.Not only
In this way, current Takeaway box largely uses polypropylene (PP), polystyrene (PS) material, and major part is all used only once
It throws away, is easy that environment is caused greatly to pollute.
The reaction principle of spontaneous backing is to accelerate oxidation reaction speed using primary battery, and chemical energy is changed into thermal energy.For
Keep temperature persistently longer, product used mineral material vermiculite to keep the temperature.Because product cannot occur instead before use
It answers so sack material will very especially, by raw material layer, gelatin layer and non-woven bag form.Non-woven bag is using microporous breathable film
Production.It must have the air-locked outer bag of routine --- gelatin layer.When in use, remove outer bag, allow inner bag (non-woven fabrics
Bag) it is exposed in air, the oxygen in air enters the inside by ventilated membrane.Exothermic time and temperature are exactly to pass through ventilated membrane
Oxygen transmission rate controlled.If oxygen flow is too fast, heat is just bled off quickly, and it is also possible to scald skin.Such as
Fruit oxygen flow is too slow, just without what temperature.The principle of oxygen uptake corrosion occurs in humid air for iron.Active carbon is utilized simultaneously
Strong adsorptivity contains vapor in the open structure of active carbon, and vapor is liquefied as water droplet, and outflow connects with air and iron powder
Touching, more rapidly reacts under the catalytic action of sodium chloride and generates iron hydroxide, releases heat.
Cathode: Fe-2e-=Fe2+
Anode: O2+2H2O+4e-=4OH-
Overall reaction: 2Fe+O2+2H2O=2Fe (OH)2
4Fe(OH)2+2H2O+O2=4Fe (OH)3↓
2Fe(OH)3=Fe2O3+3H2O
The present invention prepares a kind of heat preservation environment protection food packet of thermal insulation property simple with structure, excellent using spontaneous backing
Mounted box.
Summary of the invention
To achieve the above object, the present invention provides a kind of heat preservation environment protection food package box, including outer box, liner and box cover；
Spontaneous backing is provided between the outer box and liner.
Preferably, the cavity between outer box and liner at the bottom is arranged in the spontaneous backing.
Preferably, the spontaneous backing includes following raw materials: 53~58wt% iron powder, 2~4wt% sodium chloride, 2~
4wt% magnesium chloride, 2~4wt% active carbon, 3~6wt% vermiculite, surplus are water.
