Description
Technical field
The invention belongs to the fields that high polymer material technology and hot melt adhesive are coated with, and in particular to a kind of acrylate solid can
Adhesive and its preparation and coating method are pasted again.
Background technique
Re-binding can be used to the Notepaper pasted repeatedly, currently, re-binding rises in China.Well known solvent can be again
The shortcomings that rubberizing is it will be apparent that being exactly very not environmentally (solvent is most of harmful).Solvent type glue to the pollution of environment very
Seriously, with the raising of people's environmental consciousness and the foundation of relevant law and perfect, the application of solvent type glue is prohibited and rapid
Decline.Manufacturer's production equipment develops water base glue, has started re-binding Manufacturing Models with Chinese characteristics；Aqueous pressure
Quick high movable adhesive is connect from skill by pressure-sensitive modification, and the strong tack of voltage-dependent characteristic is poor.Re-binding performance is not sent out sufficiently
It waves, it is almost nil repeatedly to paste initial bonding strength.The performance of re-binding can be lost.More important is due to high movable pressure sensitive adhesive
Water-based nature determines that physics creep i.e. modification can be generated by meeting water as the re-binding of substrate using papery, and what it is due to painting is spacing glue,
Re-binding sheet, after gluing is folded originally, whole is bent to glue position, is attached on object, and the place of non-glue position is again to non-glue position
Aspect curling, the reason is that paper water-swellable, dries after-contraction by baking, the place without gluing also retains script
Structure, flatness is constant, thus forms the distinctive elbow phenomenon of re-binding, and need drying time long.It is compacted due to generating
Paper glue position and non-glue position after change not in the same horizontal line, so, after glue position is pasted, another parallel
On line, non-glue position is also rested on original parallel lines, so foring, re-binding is distinctive to stick up tail phenomenon.Due to now can be again
Patch coating machine baking will reach the solidification effect that certain length can be only achieved water accack.So occupied area large volume
Weight, production capacity is low, and cost energy consumption is high, can generate more waste water and sludge；Production run requires tightened up.Re-binding coating machine is logical
Cross what intaglio press transformation came.It is glued using transfer type notch board rod, electric heating bakes, it is common that aqueous pressure is synthesized using lotion
Prepared by the method for quick glue, glue is transferred on paper by anilox roll when in use, through baking oven heating, drying, is wound.Electricity

Wherein according to the viscosity of acrylate solid re-binding adhesive, coated form and substrate setting speed.
According to the above coating method, acrylate re-binding coating paper is obtained.
Above-mentioned coating method had both given full play to the function that can be pasted repeatedly, enhanced initial bonding strength, and without scratch, did not hurt
Substrate, substrate are smooth as before.It is few to can achieve coating weight, meets re-binding or the defined fine degree that loses money in a business of keeping record, maintains
The original structure of paper, it is smooth as before.Coating method is simple and effective, and production capacity is high, and production capacity improves 300%, well known existing painting
The confidential drying tunnel by up to 20m or more of cloth is baked and banked up with earth could be by glue curing, and most fast 100 ms/min of coating speed is hereinafter, and originally
The acrylate solid re-binding adhesive of invention and its coating method can not be baked and banked up with earth and also just should not with normal temperature cure
Drying tunnel, minimum speed can achieve 300 meters or more per minute.
The simple and effective simple volume of coating apparatus structure of coating method is light and handy, if well known existing coating machine speed is most
Fast 100 ms/min, length must reach 40 meters, and use the present invention, and 8 meters of coating machine extreme length, volume reduces 80%.
Production cost and electricity consumption reduce 90%, and the coating machine electricity consumption of well known existing 100 meters of speed is 200,000
Watt/hour or more.Support that electricity is 20 kilowatts/hour or less since coating method provided by the invention does not need drying equipment.
Therefore low energy consumption, and manufacturing cost is greatly lowered.
Acrylate solid re-binding adhesive is 100% solid component, is free of solvent, therefore Zero-discharge non-pollution, together
When operator will not because cleaning more than glue due to touch the toxic solvents such as a large amount of Formaldehyde and benzene.

By the solid blob of viscose of acrylate solid re-binding adhesive, launches into hot melt case, heat and maintain 120
~350 DEG C, solid blob of viscose is melted into
(2) the acrylate solid re-binding adhesive of the liquid condition of fluid state is coated on substrate, room temperature is solid
Change.The colloid for becoming liquid after fusing is transported to apparatus for coating by pressurizing device, coating is carried out to substrate.
Start in the unwinding device of coating machine, selects to use quantification of 5 μm~12 μm of thickness of BOPP film as coating base
Material selects coated form as spraying of getting to know.
The acrylate solid re-binding adhesive of fluid state is heated up to 260-300 DEG C, at this time the propylene of fluid state
The viscosity of acid esters solid re-binding adhesive be 1500-3000Pa.s, by pressure pump, glue after hot melt case circulates,
The coated die head of glue is painted in BOPP film by hydraulic device, wherein setting speed is 250 ms/min.
According to the above coating method, acrylate re-binding coating paper is obtained, quantification of 15-18g/m is glued2, glue plus
Heat arrives 150-180 DEG C, is applied on paper, coated glue layer is with a thickness of 4-6um/m2；It is cut into 25 mm wides patch on the steel plate, with
For the speed of 300mm/min from 180 angle pull-ups, detecting peeling force is 160 grams.It can paste repeatedly 300 times or more.Adhesive force is steady
Fixed, durability is good, is used multiple times, and pastes repeatedly and does not stay residue glue.
Specific case used herein elaborates inventive concept, the explanation of above example is only intended to
Help understands core of the invention thought.It should be pointed out that for those skilled in the art, not departing from this
Under the premise of inventive concept, any obvious modification, equivalent replacement or the other improvements made should be included in the present invention
Protection scope within.
