Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
The requirement of high smoothness, a side of the invention cannot be reached in order to solve the aluminum foil backing paper of existing top sizing production
Appearance is to provide technical solution below：
Embodiment one：A kind of production method of aluminum foil backing paper, includes the following steps：
Step 1, prepare glue：By starch gelatinization, when gelatinized starch temperature is down to 38 DEG C, by gelatinized starch and dispersion
Gum rosin is configured, and makes starch in the concentration 4.5% of glue, and the proportion of starch and dispersion rosin size is 2:1.
On the one hand, it should be noted that when starch concentration gradually increases, the curve of smoothness variation is first increases and then decreases
Trend.When starch concentration is 4.5%, lining paper, that is, paper smoothness of production has reached maximum.
Wherein, starch concentration will have a direct impact on the starch granules amount of keeping on paper.When starch concentration is too low, starch
It is uneven that grain is scattered in paper, continuous glue film cannot be formed, and moisture content opposite in glue at this time is then excessively high, so that paper
Moistened surface is opened, swollen, which occurs, for paper surface fiber causes to deform, so that the roughness of paper increases.
And when starch concentration is excessively high, starch granules bulk deposition on paper surface, since starch cohesive force is not powerful enough,
It is easy to cause and is easy to be subjected to displacement between each other between starch granules, produce internal friction, the glue resulted in is being glued
When the different zones glue-line of paper difference in thickness it is larger, to can also reduce the smoothness of lining paper.
For these reasons, starch concentration is too low or the excessively high smoothness that can all reduce lining paper, experiment display, when starch is dense
When degree is 4.5%, the smoothness of lining paper is in maximum point, about 450s at this time.
On the other hand, it should be noted that starch is allowed to negatively charged, when mixed with same negatively charged dispersion rosin size
When conjunction forms glue, homophilic charge is more intensive, and dispersion is more uniform, and the stability of glue is then higher.Therefore, top sizing is being needed
When, if the ratio of the two is suitble to, starch granules can uniformly be arranged on paper with dispersion rosin size particle, mutually
Filling, forms one layer of dense film, greatly improves the smoothness of paper.
Wherein, if the ratio of dispersion rosin size is too low, for entire glue based on starch, starch molecular chain has a large amount of hydroxyls
Base is easily shifted into paper, so that fine and close continuous film cannot be formed.And when dispersion rosin size ratio is excessively high, due to dispersion
The fusing point of gum rosin is lower, and paper and machine are easy to stick together by fusing when being enriched in paper, when external force removing, makes
It obtains paper surface to be destroyed by force, greatly reduces the smoothness of paper.
In conclusion when starch and dispersion rosin size ratio from height into low change procedure, the smoothness of paper
There is the process to become smaller again of changing from small to big, it is demonstrated experimentally that when the ratio of starch and dispersion rosin size is 2:When 1, at smoothness
In maximum point.
Step 2, top sizing：Configured institute's glue is subjected to top sizing to paper, sizing speed is 3m/min, on
Glue amount is 3g/m2, and it is dry in polisher.
It should be noted that when spread is 3g/m2When, glue film at this time is uniform, continuous, during sizing, glue
Liquid can be good at sprawling, while not have the micelle being excessively enriched on paper.
Wherein, the glue of top sizing can improve paper surface smoothness by the effect of two aspects, first is that logical
It crosses at filling paper surface irregularity and improves smoothness；Second is that improving the compatibility of paper and machine such as drying cylinder, increase paper
The patch cylinder opened, so as to improve the smoothness of paper by improving surface temperature of drier.
In addition, top sizing is carried out generally by surface coating machine.
Step 3：Press polish：By the water balance of paper to 6%, soft calendaring is carried out at 80 DEG C, 1.1MPa.
It should be noted that containing solid rosin particle in dispersion rosin size, fusing point is lower, is melted at 100-110 DEG C
Change, therefore use 80 DEG C, carries out soft calendaring under conditions of 1.1MPa.
In burnishing process, Paper Moisture is too low, and paper fibre interweaves close, and when press polish is not easy to unfold in time, be easy to cause
Paper fold；Moisture is excessively high, and the moisture in paper cannot evaporate in time, and the moisture in pressure area cannot exclude, and receives squeezing action,
Paper is easy to foaming.
Step 4：It is compound：Paper sizing face with aluminium foil be bonded compound.
Paper is needing to guarantee certain water absorbent surface amount with aluminium foil compound tense, could absorb certain adhesive, guarantees
Normal compound, the water content of paper is about 6% at this time.
In conjunction with the embodiments one, in embodiment two：Dispersion rosin size is the Dispersed Anionic Rosin Size of solid content 30%.
The purpose of another aspect of the present invention provides a kind of aluminum foil backing paper：
A kind of aluminum foil backing paper, aluminum foil backing paper use the above embodiments one or the described in any item production methods of embodiment two
It is made.
The present invention is by by starch gelatinization, so that the glue prepared with starch and Dispersed Anionic Rosin Size is to aluminium
Laminating tissue carries out top sizing, using starch and dispersion rosin size 2:When 1 ratio and starch concentration is 4.5%, starch granules
It can uniformly be arranged on paper with dispersion rosin size particle, fill mutually, form one layer of dense film, so that production
Aluminum foil backing paper greatly improves the smoothness of paper, requirement that is at low cost and having reached high smoothness.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
