Description
Technical field
The present invention relates to a kind of preparation methods of suction straw paper.
Background technology
Suction pipe paper is a kind of novel wrapping paper, including is used for straw, dairy produce suction pipe, package for chopsticks and toothpick packet
Dress, is a kind of high-grade special paper to grow up in catering industry in recent years, since it has clean, colourless, tasteless, nothing
Malicious and degradable advantage gradually replaces plastics package, becomes the packaging material of great competitiveness in the market at present.
But since current suction pipe paper is using conventional preparation method, cause the whiteness of suction pipe paper poor, easy influence disappears
The visual effect of the person of expense, therefore, the existing producer are added to various chemical addition agents, lead to improve the beauty of suction pipe paper
Cause suction pipe paper not nontoxic and degradable, also, there is also excessively transparent and wrinkle for the suction pipe paper obtained by existing preparation method
Problem more than pleat affects the use of suction pipe paper.
Invention content
In view of this, a kind of it is an object of the present invention to provide whiteness good, opaque and non-wrinkled advantage, can save a large amount of
The preparation method of the suction straw paper of resource.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of preparation method of suction straw paper, including following preparation process：
1) whole wood pulp material is prepared：Bleached softwood is selected to account for 70% in whole wood pulp material per ton, bleaching broad-leaved accounts for 30%, is preparing
In the process, in order to reach the beating degree of papermaking wood pulp requirement, fining-off is carried out by step in detail below：
A, first bleached softwood slurry and bleaching broad-leaved slurry are added separately in different grinders, while control grinding
Machine is ground bleached softwood slurry and bleaching broad-leaved slurry with the rotating speed of 500r/pm so that bleached softwood slurry and bleaching
Broad-leaved slurry is finer and smoother, spare；
B, it is added separately to bleached softwood slurry made from specific steps A and bleaching broad-leaved slurry to be put into ultrasonic generator
In, it is carried out at ultrasonic wave under conditions of frequency is 20KHz-25KHz, power is 100W-1000W and mashing temperature is 20 DEG C
Reason, the time of ul-trasonic irradiation continue 50min-80min so that and the beating degree of the bleached softwood slurry of processing is 80-82 ° of SR,
Weight in wet base is 7-7.5g/cm2So that the beating degree of the bleaching broad-leaved slurry of processing is 30-32 ° of SR, spare；
C, the bleached softwood slurry handled in specific steps B and bleaching broad-leaved slurry are added in regulating reservoir, in order to
Protect bleached softwood slurry and bleach broad-leaved slurry in fiber, therefore by bleached softwood slurry and bleaching broad-leaved slurry
While being delivered to regulating reservoir, the hydroxymethyl cellulose for taking 1kg/t simultaneously is needed, and in order to by hydroxymethyl cellulose and bleaching
Needle slurry and bleaching broad-leaved slurry are uniformly mixed in regulating reservoir, therefore, by double pump by bleached softwood slurry and drift
White broad-leaved slurry and hydroxymethyl cellulose are pumped into regulating reservoir simultaneously, then by being manually sufficiently stirred using stirring rod,
And while agitating be added 30kg/t PAA wet strength agents, after stirring by starching pump by mixed slurry be pumped into approach system into
The next preparation process of row, it is spare；
2) mixed slurry made from specific steps C in step 1) is delivered to by approach system in fan pump, in order to carry
The dry strength and folding strength of suction pipe paper made from high mixed slurry are added while approach system conveys in the AKD of 45kg/t
Property exhausted jelly and 10kg/t modified polyacrylamide, and be uniformly mixed in fan pump simultaneously, while being mixed in fan pump
The macromolecule modified polyacrylamide of the calcium carbonate and 3.5kg/t of addition 70-75kg/t in the process, after being mixed with mixed slurry,
So that suction pipe paper obtained is increased retention, pressurized screen is then flowed out and be delivered to from fan pump, the pressurized screen squeezes filtering,
It finally carries out three-level slagging-off and mixed slurry is made, the tailings direct emission that slurry generates is standby to ensure into the dustless Egyptian trachoma of paper
With；
3) at paper conversion：It by mixed slurry obtained after pressurized screen removes the gred, is transported in head box, while being added and going
Ionized water is diluted to 0.2-0.25% to ensure evenness, whole by head box, forming net, vacuum suction, squeezing, drying, press polish
Paper is made into after sieve, finally cuts into warehousing finished products after lateral lattice.
Further, the PAA wet strength agents in the step 1) in specific steps C are pre-prepared 15% solid content lotion.
Further, the neutral jellies absolutely of the AKD in the step 2) are pre-prepared 15% solid content lotion.
The technology of the present invention effect major embodiment is in the following areas：By to bleached softwood slurry and bleaching broad-leaved slurry difference
It is ground and is beaten, bleached softwood slurry and bleaching broad-leaved slurry and hydroxymethyl cellulose are pumped by tune by double pump simultaneously
Save pond in so that the fiber of mixed slurry is protected, then in order to improve the dry strength of suction pipe paper made from mixed slurry and
Folding strength, while neutral jelly and modified polyacrylamide absolutely is added, and add calcium carbonate and macromolecule modified polyacrylamide
Amine is added to the retention of paper, finally removes the gred by pressurized screen so that mixed serum obtained is reducing head box online
After concentration, paper is made into, therefore, the stretching tensile strength of suction pipe paper made from preparation method of the invention is good, non-toxic and tasteless nothing
Dirt and without sand hole eye, therefore have the advantages that whiteness is good, opaque and non-wrinkled, a large amount of resource can be saved.
