Abstract
The invention relates to a production method for packaging box paper. The production method for the packaging box paper includes the following steps: 1, by weight, 60 parts of pteroceltis tatarinowii bark, 40 parts of taxus bark, 0.25 part of baking soda, 3 parts of calcium carbonate and 3 parts of ethyl acetate ethanol solutions are mixed to be kneaded for 2 h; 2, the processed raw materials are added into distilled water with the weight three times that of the raw materials to be stirred for 1 h, and pulp A is obtained; 3, 8 parts of modified starch and 0.2 part of nano-silver are added into the pulp A, and ultrasonic processing is carried out; 4, heat preservation is carried out on the raw materials processed in the step 3 at the temperature of 95 DEG C, and stirring is carried out in the heat preserving process; 5, the processed raw materials are pulped; 6, the processed raw materials are formed through molds and dried, and the packaging box paper is obtained. The production method for the packaging box paper is simple; the pteroceltis tatarinowii bark, the taxus bark and the modified starch are used as the main raw materials, the produced packaging box paper can be naturally degraded, the pollution to the environment is avoided, and the packaging box paper is nontoxic and wide in application range.
Description
Technical field
The invention belongs to field of papermaking, be specifically related to a kind of production method of packing case paper.
Background technology
In view of the environmental pressure of conventional plastic packaging material strengthens day by day, develop the emphasis that degradable packaging material just become current tackling of key scientific and technical problems.But due to material and technical problem, current degradation plastic still cannot be degradable, and cost is higher, thus not yet drop into large-scale production and use.
The packaging material that natural material papermaking obtains are obtained by edible natural starch completely, can be degradable, fundamentally solve problem of environmental pollution.But when papermaking, the Timber sections of trees that uses carries out papermaking more now, and tree root and bark utilize less, especially speed of growth willow faster, seldom can be utilized, and tracing it to its cause is the second-rate of poplar root papermaking paper, not easy-formation, tearability and the tensile strength of paper are poor.
Summary of the invention
The object of this invention is to provide a kind of production method of wrapping paper, use poplar root, Cortex Cunninghamiae Lanceolatae and modified starch are prepared, and preparation method is simple, good forming effect.
The present invention is achieved through the following technical solutions:
A production method for packing case paper, uses following methods to produce:
(1) get wingceltis 60 parts, by weight, Cortex Cunninghamiae Lanceolatae 40 parts is broken into the powder that particle diameter is 3-5mm after cleaning, then mix, at 1kg/cm with the ethanolic solution 3 parts of the ethyl acetate of 0.25 part, sodium bicarbonate, 3 parts, calcium carbonate, mass fraction 10%
2pressure under crumple 2h;
(2), the raw material that step (1) is handled well is added the distilled water of raw material weight 3 times, stir 1h, obtain slurries A;
(3), add in slurries A add 8 parts of modified wheat starch, 0.2 part of Nano Silver, ultrasonic wave process 8-10min in slurries A, ultrasonic frequency is 22kHz-24kHz;
(4) raw material, by step (3) handled well, at 95 DEG C of insulation 10-15min, stirs in insulating process;
(5), by the raw material that step (4) is handled well pull an oar, beating degree is 28-32 ° of SR;
(6) raw material, by step (5) handled well uses mould molding, dries, obtains wrapping paper.
Preferably, described Cortex Cunninghamiae Lanceolatae is the bast in Cortex Cunninghamiae Lanceolatae.
The mutual friction of raw material phase can be made after wingceltis, Cortex Cunninghamiae Lanceolatae mixing fragmentation with sodium bicarbonate, calcium carbonate and ethyl acetate solution mixing rubbing in the present invention, under solvent and sodium bicarbonate effect, make fiber separation, fluffy, when ensureing paper strength, reduce the density of paper, under the abrasive action of calcium carbonate, make fiber tearing, wingceltis and Cortex Cunninghamiae Lanceolatae can also be made mutually to be wound around, make it fully contact, be not only conducive to promoting the quality of making paper, can also be conducive to carrying out making beating process, shorten the time that making beating is used, promote the quality of slurry, simultaneously, add the intensity that a small amount of calcium carbonate also contributes to promoting paper, before making beating, add a small amount of Nano Silver, Nano Silver has good anti-microbial property, control paper breed bacteria can be strengthened, and adding of Nano Silver can as node between fiber, strengthen the TENSILE STRENGTH of paper, modified starch and Nano Silver are added simultaneously, through ultrasonic oscillation, part Nano Silver is modified starch embedding, promote the intensity of paper, and extend the paper antibacterial time, prevent silver to leak pollution, and the use amount of Nano Silver is less, harm can not be produced to environment and human body.
Beneficial effect of the present invention: it is simple that method of the present invention prepares packing case paper method, use wingceltis, Cortex Cunninghamiae Lanceolatae and modified starch to be main raw material, because wingceltis price is higher, be not easy to obtain, therefore a large amount of Cortex Cunninghamiae Lanceolataes be easy to get is added in the feed, through the process of present invention process, the intensity of paper can be ensured, and the gas permeability of paper can be promoted, the wrapping paper made can natural degradation, environmentally safe, the avirulence of wrapping paper own, applied widely; And after treatment, the good permeability of packing case paper, very applicable when doing the food packs such as fruit or packing case, and also paper itself has antibacterial performance, and mushroom can not be caused to strengthen the resistance of antibacterials.
Detailed description of the invention
A production method for packing case paper, uses following methods to produce:
(1) get wingceltis 60 parts, by weight, Cortex Cunninghamiae Lanceolatae 40 parts is broken into the powder that particle diameter is 3-5mm after cleaning, then mix, at 1kg/cm with the ethanolic solution 3 parts of the ethyl acetate of 0.25 part, sodium bicarbonate, 3 parts, calcium carbonate, mass fraction 10%
2pressure under crumple 2h;
(2), the raw material that step (1) is handled well is added the distilled water of raw material weight 3 times, stir 1h, obtain slurries A;
(3), add in slurries A add 8 parts of modified wheat starch, 0.2 part of Nano Silver, ultrasonic wave process 8-10min in slurries A, ultrasonic frequency is 22kHz-24kHz;
