Technical field
The invention belongs to field of papermaking, and in particular to a kind of manufacture of paper of papermaking plasm-glue-blending.
Background technique
Directly sizing papermaking is existing common one of papermaking process in slurry, and sizing paper technology is: using metering pump
Approach system adds sizing agent before paper machine net, then by keeping the processes completion such as manufacture paper with pulp, dehydrate.And in this slurry directly
The method of sizing is lost there is part sizing agent and immerses the plain boiled water circulatory system, increases systemic contamination degree, and sizing agent
It is bad to adsorb application effect, causes the usage amount of sizing agent larger, improves processing cost, and paper obtained is easily in the presence of disconnected
The problems such as paper, hole, influences it and uses quality.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of manufacture of paper of papermaking plasm-glue-blending is provided.
The present invention is achieved by the following technical solutions:
A kind of manufacture of paper of papermaking plasm-glue-blending, includes the following steps:

By alkyl ketene dimer, diallyl dimethyl ammoniumchloride, cationic starch according to 90 ~ 100:6 of weight ratio ~
8:1 ~ 2 carry out mixing be put into agitator tank, high-speed stirred uniformly afterwards take out be cooled to room temperature compound sizing agent is spare；
(2) composite papermaking slurry preparation:
A. compound sizing agent made from step (1) is added in pre-prepared pulping, after being stirred continuously uniformly
It is spare to obtain slurries A；
B. ultraviolet irradiation processing is carried out to slurries A made from operation a, it is spare to obtain slurries B after 30 ~ 40min；
C. inorganic filler components are added in slurries B to made from operation b, be stirred continuously to after uniformly composite papermaking slurry is standby
With；
(3) paper making:
A. composite papermaking made from step (2) is starched and carries out paper making processing, it is spare to obtain semi-finished product paper A after the completion；
B. squeezing processing is carried out to the operation resulting semi-finished product paper A of a with hydraulic press, obtains semi-finished product paper after 1 ~ 1.5min
B is spare；
C. microwave drying treatment is carried out to the resulting semi-finished product paper B of operation b, gets product paper after 5 ~ 7min.
Further, the speed of high-speed stirred as described in step (1) is 1200 ~ 1400 revs/min.
Further, step (2) operation a described in compound sizing agent additive amount be pulping gross mass 0.2 ~
0.4%。
Further, step (2) operation b described in ultraviolet irradiation processing when ultraviolet light wavelength control be 260 ~
280nm。
Further, it is any one in calcium carbonate, talcum powder, kaolin that step (2), which operates inorganic filler described in c,
Kind, the amount of addition is the 0.05 ~ 0.1% of pulping gross mass.
Further, the concentration of composite papermaking slurry described in step (2) operation c is 5 ~ 6%.
Further, pressure when squeezing processing described in step (3) operation b is 0.25 ~ 0.35MPa.
Further, the power of microwave is 400 ~ 500W when microwave drying treatment described in step (3) operation c.
Alkyl ketene dimer is the most widely used neutral-to-alkaline sizing agents of current paper-making industry, the parent between cellulose
Preferable with associativity, integrated quality is high；It finds to contain a large amount of anionic impurity and tiny in pulp slurry in actual use
Fiber etc., and such anionic impurity and fiber fines can adsorb a part of alkyl ketene dimer of consumption, reduce alkyl alkene
Fixed amount of the ketone dimer on bulky grain fiber, so that whole sizing efficiency and paper quality are reduced, to this present invention
A kind of compound sizing agent has first been prepared, it, can be first in effective Adsorption slurries wherein be added to cationic starch ingredient
Anionic impurity ingredient, while can be combined again with fiber fines, alkyl ketene dimer is improved on bulky grain fiber
Effective fixed amount, wherein also addition used diallyl dimethyl ammoniumchloride ingredient, improve the cream of sizing agent particle
Change dispersion effect, and then improve compound sizing agent to the uniformity of size application and stability on fibre composition surface, prepares slurries B
Period has carried out ultraviolet irradiation processing, under ultraviolet irradiation processing, surface active groups content on bulky grain fiber and
Activity is promoted, and has very big enhancing with the bond strength of alkyl ketene dimer, improves the application effect of compound sizing agent
Fruit usually requires addition filler ingredient in pulping, and filler is applied at being placed in after compound sizing agent addition process, can be had
The combination for avoiding filler and compound sizing agent effective component of effect, it is fine in bulky grain also for alkyl ketene dimer is promoted
Effective fixed amount in dimension；After the completion of paper making, semi-finished product paper A contains a large amount of moisture, at this time in compound sizing agent
Alkyl ketene dimer a part be through Electrostatic Absorption on bulky grain fiber, binding force is not strong, and conventional method is to adopt
With drying process, to reduce influence of the moisture to alkyl ketene dimer, but simple reduction moisture, promoted environment temperature for
The promotion degree of sizing efficiency is little, and to this present invention, first double of finished paper A carries out squeezing processing, and it is tentatively fixed to carry out to paper
Type, external force remove large quantity of moisture, lay the foundation for subsequent operation, and the drying of paper is then carried out using the method for microwave drying,
Microwave drying at this time is not only used to remove Paper Moisture, changes the combination of alkyl ketene dimer and paper fibre Electrostatic Absorption
Mode, while groups activity and the content such as hydroxyl in microwave treatment energy reinforcing fiber element, promote alkyl ketene dimer molecule
In lactonic ring and cellulose in the groups activity such as hydroxyl chemically react, generate the ingredients such as 'beta '-ketoester, both enhance
Between binding ability, to improve the effect of sizing.
The present invention has the advantage that compared with prior art
The present invention has carried out reasonable adjustment to whole processing technology prepared by paper and has improved, hence it is evident that improves sizing agent and exists
Effective retention in papermaking pulp fibres enhances absorption bond strength between the two, so as to improve the use quality of paper,
Made paper water-resistance, folding resistance, hardness etc. have fine promotion, the great market competitiveness.
