Fruit paper bag is produced using the long fine slurry of 100% needlebush, through high concentration mashing.The fruit paper bag of the method production, production of units
With wood pulp amount is big, electricity consumption is high, manufacturing cost is high, and client is difficult to receive such higher-priced fruit paper bag.Do not have at present yet
It was found that, for this purpose, being suitble to meet customer need for production, expanding market with the document of Deinking Pulp production such use fruit paper bag and occupying
Rate promotes product competitiveness, makes full use of and play the advantage that our company has production regeneration Deinking Pulp, and our company tissue researches and develops people
Member mixes regeneration Deinking Pulp production fruit paper bag in fruit paper bag production, and improves prior art technology and wet end furnish, to reach
To the production cost for reducing fruit paper bag.
Summary of the invention
Therefore, for the above content, the present invention provides a kind of preparation method of Deinking Pulp fruit paper bag, solves the prior art
The problem of high production cost.
A kind of preparation method of Deinking Pulp fruit paper bag, the following steps are included:

By Deinking Pulp size degradation, the revolving speed of pulper is 300-400r/min, beating time 30-60min, in pulper
The mass concentration of Deinking Pulp is maintained at 3-5%, and the slurry in pulper is removed impurity by aperture 3mm sieve, then uses disk
Grinding machine is beaten, and beating degree control adjusts pH to 7 in 75-85 ° of SR, obtains storing after deinking slurries spare；By needle starch into
Row size degradation, the revolving speed of pulper are 500-600r/min, beating time 30-60min, and the quality of the needle slurry in pulper is dense
Degree is maintained at 3-5%, and the slurry in pulper is removed impurity by aperture 3mm sieve, is then beaten, is beaten with disc mill
Degree of beating control adjusts pH to 7 in 75-85 ° of SR, obtains storing after needle slurries spare；
B, slurrying process
Deinking slurries and needle slurries difference weight percent 40-80%, 20-60% mixing for taking step A to obtain, to
Cation guar gum is added in the mixed slurry, dosage is the 0.08-0.15% of oven dry stock weight, is uniformly mixed, is added and increases
White dose；
C, desanding
Above-mentioned mixing slurry is successively copied to forebay, header box, intermediate pool, removes sand pump and desander desanding；In the high position
The PAE wet strength agent (calculating by 100% content) of oven dry stock weight 3-4% is added in the case stage；
D, pulp flow and online process
The obtained slurry of step C is streamed, during the streaming, the concentration of slurry is diluted to mass fraction
It is 0.5~0.9%, while removes the weight impurity of the slurry；Be added account for oven dry stock weight 0.5-1% cationic starch,
Preservative and pigment is added in the paraffin wax emulsions of the emulsion acrylic resin of 20-30%, 10-15%, defoaming agent 0.01-0.15%,
Then online process is completed；
E, paper making controls process
Slurry in step D is sent into after machine chest and is diluted by plain boiled water, flow box dehydration, drying, top sizing, finally
It is formed by soft calendaring ornamenting；The top sizing agents useful for same is grouped as by each group of following parts by weight: phosphate ester starch 80-
90 parts, 10-20 parts of sodium carboxymethylcellulose, 0.5-1 parts of defoaming agent, 0.1-0.3 parts of preservative；
F, paper postprocessing working procedures
Sheet paper or roll web, finished product are processed into the paper bowl cutting that step E is obtained.
A further improvement is that: the acrylic emulsion solid content 35%.
A further improvement is that: the paraffin wax emulsions solid content 30%.
A further improvement is that: the proportion of the deinking slurries and needle slurries is 5:5.
A further improvement is that: the dosage of the PEA wet strength agent is the 3.5% of oven dry stock.
By using preceding solution, the beneficial effects of the present invention are:
1. the present invention is reduced the long fine slurry dosage of needle, is increased regeneration Deinking Pulp dosage, save and use by optimization wet end furnish
Electricity.
2. adding retention agent cation guar gum in the slurry, the loss of fiber fines is reduced, reduces unit usage of sizing agent.
3. fruit paper bag wet strength and tearability are effectively improved, with propylene within the scope of experimentally determined PAE wet strengthening agent
Acid resin replaces filler kaolin in the prior art etc., and finished product transparency is high, paraffin wax emulsions is added, finished product is fine and smooth, moisture retention
Good, whole finished product physics dry strength and wet strength are high, and transparency is good, fine and smooth Micron Technology, can show the aesthetics of fruit and comfortable
Sense.
