Description
Technical field
The present invention relates to a kind of paper woods.
Background technique
With a large amount of uses of smart phone, takes out industry and enter a flourishing epoch, people need to only open mobile phone
Middle take-away software, can order the take-away of various cuisines.The prosperity for taking out industry also brings huge test to environment, at present
It takes out cutlery box used in industry to be made of plastics mostly, can hardly degrade, it is big to environmental hazard, also occur one in the market
A little degredation plastic cutlery boxs, the degradation cycle of these degradation plastics is still longer, generally several years, the more than ten years it is even tens of
Year, while many poisonous and harmful substances can be also generated during degrading；In order to solve the problems, such as degradation, a small number of takeout food boxes are used
Tinfoil paper or cardboard are made, but they can not replace plastics cutlery box, the reason is as follows that:
The first, tinfoil paper price is higher, cracky, and tinfoil paper thermal conductivity is good, when containing the higher food of temperature, the temperature of tinfoil paper
Degree is suitable with the temperature of food, and dispatching person and user is be easy to cause to scald；
The second, paper meal heat resistance is poor, and when the temperature of food is at 75 degrees Celsius or more, paper meal can be carbonized hair
Huang, the cutlery box meeting contaminated food products of carbonization, endangers the health of a person sponging on an aristocrat.
Summary of the invention
In view of this, the present invention provides a kind of paper wood heat-resist, capable of being fast degraded, suitable for manufacturing food packaging.
The present invention be solve its technical problem and the technical solution adopted is that:
A kind of paper wood, including press following weight proportion ingredient:
Dried leaf 20-40%, the dried leaf are yulan trunk leaf, bodhi tree cured leaf, loquat cured leaf, pine tree cured leaf
One of or it is a variety of；
Fresh leaf 10-30%, the fresh leaf are yulan tree fresh leaf, bodhi tree fresh leaf, loquat fresh leaf, pine
Set one of fresh leaf or a variety of；
Leaf epidermis 5-20%, the leaf epidermis are yulan leaf epidermis, bodhi tree leaf epidermis, Buddha's warrior attendant cane leaves table
One of skin, Chinese parasol leaf epidermis, white poplar leaf epidermis are a variety of；
Vein fiber 10-50%.
A kind of paper wood as described above further includes the natural gum that weight proportion is 1-10%.
A kind of paper wood as described above, the natural gum are pine tree natural gum, mango natural gum, Arabic gum, bassora gum, peach
One of glue, larch arabinogalactan are a variety of.
A kind of paper wood as described above further includes the pectin that weight proportion is 0.1-5%.
A kind of paper wood as described above further includes the modified starch that weight proportion is 3%-10%.
A kind of paper wood as described above, the vein fiber are yulan leaf arteries and veins fiber, Smilax china L vein fiber, bodhi
One of leaf arteries and veins fiber, Chinese parasol leaf arteries and veins fiber, white poplar vein fiber are a variety of.
Compared with prior art, the invention has the following beneficial effects:
1, raw material used by paper wood of the invention is natural material, and primary raw material both is from leaf, this paper wood system
At product in the natural environment can be degradable in one month, in environmental sound and traditional handicraft use trees branch
Dry to compare as raw material, the period of the growth of leaf is shorter, and resource is richer, is conducive to sustainable development.
2, other than quick characteristic of degrading, paper wood of the invention is also had the performance of high temperature resistance, in 140 degrees Celsius of temperature
It can still maintain a long-term stability without being carbonized in degree, may replace plastic food packing, be conducive to eliminate white pollution.

Test example
1, the heat-resisting test experiments of paper
Paper wood produced as sheets in Examples 1 to 5 is individually positioned in the hot pressing platform of hot press with a thickness of 0.1mm
On, hot pressing 10 minutes, then take out paper wood, whether observation paper turns to be yellow carbonization.Simultaneously with the Food Packaging Paper of 0.1mm thickness
As control sample 1, the A4 paper of 0.1mm thickness is as control sample 2.Test result is as shown in table 1.
1 paper wood heat resistant test of table
The test result shown from table 1 can be seen that common paper wood is resistant on the market temperature 80 DEG C with
Under, and the temperature that paper wood of the present invention is resistant to is at 140 degrees Celsius or more, wherein in embodiment 1, embodiment 2 and embodiment 5
The temperature that is resistant to of paper wood be even more to have reached 160 degrees Celsius, it is suitable with the tolerable temperature of plastic food packing.Therefore, originally
The food packaging of the paper wood production of invention may replace plastic food packing, be conducive to eliminate white pollution.
2, paper wood Degrading experiment
By the paper wood produced as sheets in Examples 1 to 5, size thickness is suitable with common A5 paper, is immersed in respectively same
In one barrel of tap water.The Food Packaging Paper of A5 size is as control sample 1 simultaneously, and common A5 paper is as control sample 2.Each paper
Material natural degradation in tap water, when with the whole chemical conversion fragments of paper, and all fragment areas are both less than 1cm2When, used in record
Time, using this time as the initial breakdown time.Test result is as shown in table 2.
2 paper wood Degrading experiment of table
| Paper wood | The initial breakdown time |
| Embodiment 1 | 5 days |
| Embodiment 2 | 4 days |
| Embodiment 3 | 5 days |
| Embodiment 4 | 5 days |
| Embodiment 5 | 4 days |
| Control sample 1 | 6 days |
| Control sample 2 | 7 days |
The initial breakdown time that the test result shown from table 2 can be seen that common paper wood on the market is generally 6~7
It, and the paper wood initial breakdown time of the present invention is generally 4~5 days, degradation time is faster than plain paper.
Raw material used by paper wood of the invention is natural material, and primary raw material both is from leaf, environmental sound, and
It is compared using the limb of trees as raw material in traditional handicraft, the period of the growth of leaf is shorter, and resource is richer, and being conducive to can
Sustainable development.
The effect of pectin is to be bonded together the plant fiber in paper wood, increases the intensity of paper wood, while pectin is thin
It is aqueous can also to make paper wood of the invention that there is certain waterproofness.In paper wood of the invention, fresh leaf and dried leaf should be adopted
With the high leaf of pectin content, listed yulan tree fresh leaf, the bodhi tree fresh leaf, loquat enumerated in 5 above-mentioned embodiments
Setting fresh leaf, pine tree fresh leaf, yulan trunk leaf, bodhi tree cured leaf, loquat cured leaf, pine tree cured leaf is that pectin content is high
Leaf, it is therefore an objective to make the content of pectin in the paper wood of final molding between 1%~10%.Therefore, when fresh leaf and dried leaf
When dosage is larger, can not have to additional addition pectin then can be additional when fresh leaf and less dried leaf dosage
Add some pectin.
Vein fiber is a kind of natural high strength fibre, using vein fiber as the reinforcing fibre in paper wood of the present invention
Structure can increase the toughness of paper wood of the present invention, promote its compression strength and tensile strength.Vein fiber and other compositions simultaneously
Combination can increase the heat resistance of paper wood of the present invention.
Leaf epidermis contains biowax, and its main function is to promote the hydrophobicity of paper wood of the present invention, while can increase
The pliability of paper wood.
