Description
Technical field
The present invention relates to pulp technology for making paper, more particularly to a kind of digital label paper and its production method.
Background technology
Digital label paper is the special technology of label industry production and label paper with applying mechanically paper, digital label paper performance indications
It is required that high, manufacturing process is complicated, and technical difficulty is big, and it is poor that digital label paper in the market has a flexibility, poor flexibility,
The water-fast resistance to temperature difference, tear-resistant degree is poor, and washable and wearable effect is poor, the shortcomings of print distinctness is poor, and therefore, in the market, which is needed badly, to be had
The digital label paper of standby high-quality advantage.
The content of the invention
The invention solves the problems that there is provided a kind of digital label paper and its production method, solution for the problem of above-mentioned prior art is present
Flexibility that certainly current digital label paper is present is poor, poor flexibility, the water-fast resistance to temperature difference, tear-resistant degree is poor, washable and wearable effect is poor,
The problem of print distinctness is poor, meets the demand of digital label paper.
The present invention solves the technical scheme that its technical problem is used：This digital label paper, it is by following parts by weight
Raw material proportioning is made：40 parts~60 parts of long fibre wood pulp, 5 parts~15 parts of sisal hemp pulp, 30 parts~50 parts of chemical fibre, wet strength agent
0.5 part~3 parts, 30 parts~40 parts of latex coating, 5 parts~8 parts of dispersant.
Further, above-mentioned digital label paper, it is made up of the raw material proportioning of following parts by weight：Long fibre wood pulp 50
Part, 10 parts of sisal hemp, 40 parts of chemical fibre, 2 parts of wet strength agent, 35 parts of latex coating, 6 parts of dispersant.
Further, long fibre wood pulp is softwood pulp.
Further, chemical fibre is terylene.
Further, wet strength agent is polyacids ester.
Further, latex coating is propionic ester.
Further, dispersant is polyacrylamide.
The production method of above-mentioned digital label paper, comprises the following steps：
The first step, mashing processing, hydrabrusher is inserted after long fibre wood pulp, sisal hemp pulp and chemical fibre are sufficiently mixed
In add water progress mixing size degradation processing, size degradation processing after be output in half stock tank, then again be pumped into slurry car in be slightly beaten,
Beating consistency is 3.0%~3.5%, and beating degree is 15 ° of SR~20 ° SR, and paper pulp is obtained after the completion of mashing, then paper pulp is exported
Match somebody with somebody into slurry in stock tank；
Second step, adds auxiliary agent, and wet strength agent is added into paper pulp of the slurry with stock tank, and carries out uniform stirring, then
It is output to and is copied in preceding machine chest again；
The paper pulp copied in preceding machine chest is manufactured paper with pulp into body paper, double cylinders by the 3rd step, processing of manufacturing paper with pulp using twin cylinder machine
The operating rate of paper machine is 75m/min；
The body paper for completion of manufacturing paper with pulp is carried out dip coated, using painting during coating by the 4th step, coating process using latex coating
Cloth machine is coated, and coating concentration is 25%~30%, and coating machine operating rate is 90m/min；
5th step, into paper, the body paper after the completion of coating is first dried using floated baking oven, then is carried out using drying cylinder
Dry, the temperature of floated baking oven is 120 DEG C~140 DEG C when drying, the temperature of drying cylinder is 90 DEG C~110 DEG C, is passed through again after drying
Cutting obtains into paper；
Acquisition is carried out press polish processing by the 6th step, press polish processing into paper using supercalender；
7th step, packaging and storage will carry out sheet again into paper after press polish is handled and draw squares processing, then examined
Test, vanning packing is carried out after the assay was approved, is then put in storage.
In the art, long fibre wood pulp refers to the wood pulp that fibre length is 2 millimeters~3.5 millimeters, and softwood pulp refers to
Be to use paper pulp made from needlebush, the fibre length of softwood pulp is 2 millimeters~3.5 millimeters, meets long fibre wood pulp
Standard.
It is fine that long fibre wood pulp, sisal hemp pulp and chemistry are contained on the digital label paper and its production method of the present invention, raw material
Dimension, sisal hemp pulp refers to the paper pulp being made of sisal hemp, individually made using long fibre wood pulp and Japanese paper adhesive tape base paper long fibre knot
Close close, but long fibre is easily broken, just occurs that the main component in the problem of low intensity, tear resistance are poor, sisal hemp pulp is
Sisal fiber, the fibrocyte of sisal fiber is in elongate structure, and lumen is big and grows, wall thickness, therefore, possess it is strong but pliable in texture,
High resilience, strong pulling force, rub resistance, acid and alkali-resistance, advantage that is corrosion-resistant, being difficult skidding, therefore, by sisal hemp pulp and long fibre wood pulp
Combine, it becomes possible to improve papery tough and hard wear resistant performance and obtain good elastic performance, solve long fibre wood pulp not
Foot part, adds chemical fibre, chemical fibre uses terylene, it becomes possible to the higher tensile strength of acquisition and tearability, press polish
Processing, can obtain good printing effect, it is ensured that the fine definition of printed digital, be coated with using propionic ester latex, further
Water-fast washable and wearable decay resistance is obtained, while making digital label paper that there is preferable flexibility, passes through the mutual knot of raw material
Cooperation is used, then the step of process production method is produced, and the digital label paper produced can solve the problem that current digital label
Paper exist flexibility is poor, poor flexibility, the water-fast resistance to temperature difference, tear-resistant degree is poor, washable and wearable effect is poor, print distinctness is poor
Problem, meets the demand of digital label paper, with having good dry, wet strength and resistance to leafing intensity, with excellent tear-proof
Performance, intensity requirement when disclosure satisfy that following process and be actually used is not stratified, with good elasticity and flexibility, tool
Standby good water-fast, solvent resistance, with good wear-resisting, wash durability, with good profile pattern and printing
Performance, meets the use demand of digital label paper.
The invention has the advantages that：The digital label paper and its production method of the present invention, the digital label produced
Paper, quality is high, best in quality, possesses following advantage：
First, with good dry, wet strength and resistance to leafing intensity, with excellent tear resistance, it disclosure satisfy that follow-up
Intensity requirement when processing and be actually used, it is not stratified；
2nd, with good elasticity and flexibility；
3rd, possess good water-fast, solvent resistance, with good wear-resisting, wash durability；
4th, with good profile pattern and printing performance.
