Description

A kind of polypropylene film offset plate and its manufacturing method
Technical field
The present invention relates to offset plate paper and its manufacturing methods, specifically using polypropylene film as base version, with water-soluble resin Slurry is the offset plate and its manufacturing method of solvent manufacture.
Background technique
For a long time, the zinc oxide offset plate paper both at home and abroad for gently printing all is to make version with paper base, using toluene, diformazan The raw materials such as benzene, first methyl esters, first butyl ester are configured to the adhesive of organic solvent type, then are configured to coating, coating system with zinc oxide etc. At millboard.This millboard, first is that solvent for use contains the composition that is harmful to the human body, the volatilization meeting pair of pernicious gas in production process Operator will cause the harm on body and the pollution to surrounding enviroment.Since these organic solvents are inflammable volatile, so Want especially careful in storage, transportational process.Second is that paper base version is manufactured by raw material of wood pulp, with the shortage of timber resources, Not only price is rising steadily, and also increases the consumption of timber resources.Third is that existing zinc oxide printing plate paper is all single side coating, user It is used only once and just throws away millboard, customer using cost is high.
Summary of the invention
For above situation, the object of the present invention is to provide a kind of polypropylene film offset plate and its manufacturing methods, with poly- Acrylic sheet is version base, and using water-soluble resin slurry as solvent, two-sided coating coating overcomes and asks existing for above-mentioned zinc oxide printing plate paper Topic.
The purpose of the present invention is what is be achieved through the following technical solutions.The system of preparation, coating color including resin slurry Standby, plate coating preparation, coating process, is cut and six parts of packaging the selection of polypropylene film.
The preparation of 1 resin slurry
1.1 technical formula
Polyvinyl alcohol (PVA-1799) 13-15kg
Purified water 160-170kg
1.2 preparation method
The purified water of formula ratio 85%-90% is added in container (or reaction kettle), starts to stir, heat simultaneously, make water Temperature rise is to 25-27 DEG C；Then the direct cloth of PVA is spread in vortex while stirring, is not allowed on PVA floats on the surface, because staying in table PVA may agglomerate and be not easy to disperse on face；The solid material being attached on stirring blade and chamber wall is washed down to continue to stir, it is sufficiently mixed It is bonded to and is homogenized；It is heated to 90-95 DEG C with steam again, 25-30min is at least stirred at this temperature, dissolves PVA sufficiently.Most Surplus purified water is added afterwards, is cooled to room temperature while stirring, it is spare.
The preparation of 2 coating colors
2.1 colorant formulas
Purified water 68kg
Ethyl alcohol 3.5-4.0kg
Pigment (methylenum careuleum or rose-red) 0.1-0.2kg
The preparation of 2.2 colorants
Purified water and ethyl alcohol are added in a reservoir, then pigment is put into alcohol water and is sufficiently stirred, is uniformly dispersed, storage 24 is small When more than, dissolve pigment sufficiently, it is spare.
The preparation of 3 plate coating
The formula of 3.1 coating
The preparation of 3.2 coating
According to formula, resin slurry is added in a kettle, stirring is heated up to 90-95 DEG C, mixing time 30-35min, Be added in colloid mill together with purified water, colorant after taking-up, then Jiang Gao ling soil, barium sulfate, calgon, precipitated calcium carbonate, Zinc oxide is added in colloid mill, and jitter time 2-3 hours.Defoaming agent is added portionwise in optic vesicle foam situation, then crosses 200 meshes, standby With.
The selection of 4 polypropylene films
It chooses with a thickness of 125-135g/m2, the polypropylene film coiled strip that width is 850-950mm, film is two-sided through hair side Process, to meet the technique requirement of coating coating.
5 coating process
Coating is using single coating head coating machine.The tow sides coated version coating on polypropylene film.Coating machine driving speed Degree control is 8-10 meter per second, and speed speed directly affects the quality of coating；Using 0.6 steel wire scraper, (0.6 is wound around for coating The steel wire diameter of scraper is 0.6 millimeter), the thickness of coating is controlled, coated coating dosage is every square metre of 7g-8g；Coating machine Drying uses bridge-type baking oven, and channel is 20 meters long, and drying temperature is 100 DEG C -105 DEG C, and the high polypropylene film of temperature is easy to split version, temperature Spend low easily dirty version.Make the water content 4.5-7% for being coated with hectograph, smoothness reaches 80s-120s；Specific gravity is 1.2-1.4.It is positive and negative The technique of two sides coating is just the same, guarantees that the coating weight of version is consistent.
6 cut and pack
Winding up roller after winding is cut out with hilted broadsword cut paper is disconnected, is cut into the vanning factory of various specifications model.
The beneficial effects of the present invention are first is that, instead of wood pulp paper base version, can be saved timber using polypropylene film Resource, and 5 times of printing or more can be improved；Second is that using polypropylene film double spread, can two-sided Plate making printing, improve hectograph benefit With rate；Third is that solving pernicious gas instead of organic solvent with water-soluble solvent and being damaged to human body and to environmental pollution problem. Polypropylene film offset plate preparation method is simple, low in cost, is a kind of ideal offset plate.
Detailed description of the invention
The present invention is without attached drawing.
Embodiment
The preparation of 1 resin slurry
Formula ratio 140kg purified water is added in a kettle, carries out agitation heating, water temperature is made to rise to 27 DEG C；Then side is stirred It mixes side to be directly spread in vortex 15kg PVA, mix to being homogenized；93 DEG C are heated to steam again, constant temperature stirs 30 minutes； Finally 25kg purified water is added, is cooled to room temperature while stirring, it is spare.
The preparation of 2 coating colors
68kg purified water and 3.5kg ethyl alcohol are added in a reservoir, then 0.1kg pigment (methylenum careuleum or rose-red) is put into alcohol It is dispersed with stirring in water uniformly, it is storage 24 hours or more, spare.
