Abstract
A method for coating a support material, with a coating substance, on a known coating device, using the so-called rolling-doctor process, is disclosed. Said method is characterised in that the coating parameters of the coating device and the composition of the coating substance are chosen to suit the surface properties, such that a layer forms on the support material, comprising irregularly distributed drops of various sizes.
Description
The present invention relates to the field of sticking tablet, wherein, adhesive is on separating film or the carrier thin film separably, and transfers on the substrate under the situation of pressurization.Therefore the present invention relates to a kind of vertically hung scroll shape one side scribble adhesive layer carrier material manufacture method and as a kind of coating substance that is used to be coated on the carrier material of intermediate products.Carrier material can for example relate to paper, plastic sheeting or metal forming, and they are through silicidation in case of necessity.
Carrier material one side by this type can be known with adhesive coating comprehensively.The sticking tablet of this coating for example is applied in the coating rolling device illustrated in EP-0 267 396.Wherein, vertically hung scroll shape carrier material is the comprehensive coating of a side at first, then is cut into fillet and is wound into reel.This reel is packed into then and is coated with in the rolling device as standby reel.By rolling device, adhesive layer can be coated on smooth substrate for example on the paper.By tractive motion, make adhesive layer and its carrier material separate and transfer in the substrate by the coating rolling device here, to the substrate that will add adhesive.The carrier strip auto reeling of unstowing is in the coating rolling device.
When adhesive layer is transferred in the substrate by the coating rolling device, confirmed already, because the cohesiveness of adhesive can not reach the avulsion glossily of adhesive layer and carrier material, because adhesive is put wire drawing in avulsion.
For fear of this disadvantageous effect, by the known a kind of carrier material of DE 94 07 704U, it is by replacing comprehensive adhesive layer by the coating of forming one by one.The advantage of this point-like coating is can obtain smooth avulsion line when being coated on adhesive layer in the substrate, because " wire drawing " do not occur (Fadenziehen) in the zone of coating adhesive between dots of adhesive.
The point-like coating of carrier material especially realizes by flexographic rotary printing art (relief printing plate roller coating) usually by for example typography under so-called " hot-melts " situation.This process is very complicated and expensive.
Therefore the purpose of this invention is to provide a kind of quick coating process, this method can stick with glue agent point-like coating carrier material, the cheap and operation simply of this external enwergy.Another purpose is a kind of adhesive of preparation, can carry out by method of the present invention with it.
The coating of this point-like is applied on the carrier material by a kind of known coating apparatus by the present invention.By its traditional application, this coating apparatus is used for comprehensively and coating equably.Confirmed unexpectedly already that this same coating apparatus also can be used in to having the carrier material coating of point-like coating.But the traditional application mode that is used for evenly coating with coating apparatus is different, select rightly and the carrier material of assembly adhesive stick and certain in case of necessity technological parameter by the present invention, obtain a kind of coating of forming by some uneven dot patterns basically thereby replace uniform coating.
Here, the selectable operational factor of coating apparatus is mated rightly with each adhesive material and carrier material, so that obtain described point-like coated pattern.
Usually the bonding comprehensively bonding force that maximum is provided.Employing sticks with glue the foil-like support material of agent coating by method preparation of the present invention, they according to said method provide so high dots of adhesive density, so that this dot density can compare with the more approaching 100% desirable covering comprehensively of general mechanical typography with simple mode as intaglio printing or flexographic rotary printing art.However do not observe the disadvantageous situation of comprehensive coating that preface is mentioned, as " wire drawing ".
Further specify by form of implementation of the present invention referring to accompanying drawing.
The work of Fig. 1 illustrative coating apparatus according to said method;
Fig. 2 schematically illustrates another kind of rolling scraper coating apparatus structure;
Fig. 3-5 is depicted in the different layouts of rolling scraper in the coating process.
As seen from Figure 1, coating apparatus comprises the groove 1 of containing liquid coating substance 2 in one.The cylindrical roller 3 that is coated with immerses in the coating substance 2.The axis that is coated with roller is a little more than the surface of coating substance 2 and extend perpendicular to the figure paper plane in Fig. 1.Being coated with roller 3 is rotated around its axis by motor drives.This rotatablely moves and carries out in the counterclockwise direction in Fig. 1.
This coating apparatus also comprises 4,5 and pressure rollers 6 of two slewing rollers.The axis of slewing rollers 4,5 and pressure roller 6 is parallel to the axis that is coated with roller 3 respectively and extends.Slewing rollers 5 and pressure roller 6 can move along the vertical direction perpendicular to its axis respectively.
The vertically hung scroll shape carrier material 7 that is coated with is along 4,5 guidings of two slewing rollers.Carrier material 7 is pulled out (not expression Fig. 1) in the end that it is in first slewing rollers, 4 fronts from standby reel.Be positioned at the place, end after second slewing rollers 5 its another, carrier material is wound on (expression among Fig. 1) on the cylindrical sleeve by coiler device.The coiling of coating is undertaken by rotatable chill roll with the effect of spreading and drive unit.Drive unit makes chill roll rotate around its axis, so carrier material 7 pulled out from standby reel, via slewing rollers 4,5 guidings and be wound on the winder.
Between the pressure roller 6 and second slewing rollers 5, adorn a rolling scraper 8.Rolling scraper 8 is made of a thin bar with external screw thread type.The axis of bar is parallel to the axis that is coated with roller 3 and extends.Mode as an alternative, rolling scraper also can be made of the thin bar of its outside coiling fine wire.Except that the rolling slurry-scraping method, also can use other layouts of funny point-like scraper and the rolling scraper shown in Fig. 3 to 5 shown in Figure 2.The upright position that rolling scraper 8 is arranged to make it is substantially in two slewing rollers 4 and 5 two the imaginary line between bottom.Pressure roller 6 can be vertically so mobile, makes it at a lower position carrier material 7 not only is pressed in rolling scraper 8 upsides but also be pressed in and be coated with roller 3 upsides.
The coating of coating substance 2 on carrier material 7 undertaken by following mode:
When being coated with roller 3 and rotatablely moving, coating substance 2 is attached on the outside that is coated with roller 3.When carrier material 7 is pressed in when being coated with on the roller 3 by pressure roller 6, can be coated in all sidedly on the downside of carrier material 7 attached to the coating substance 2 that is coated with roller 3 outsides.Because carrier material 7 spurs through slewing rollers 4,5 by coiler device, so carrier material 7 obtains a planar coating.Be coated with between roller 3 and the rolling scraper 8, on the carrier material 7 of carrier material 7 downsides, constituting a more or less uniform coating substance layer.The thickness of this uniform coating depends primarily on the character of coating substance and the surface characteristic of carrier material here.
And then, the downside of carrier material 7 is pulled by rolling scraper 8.This rolling scraper 8 is rotated around its axis by motor drives.Form as an alternative, rolling scraper 8 also can transfixion.
Rolling scraper 8 strikes off the part of comprehensive coating from carrier material 7.The coating substance 2 that strikes off flows back in the groove 1 subsequently.All the other coating substances of staying on the carrier material 7 constitute a uniform coating there usually.
Yet unexpectedly confirm, under the situation that the composition and the surface characteristic of carrier material 7 of coating substance 2 are mated rightly (back also will illustrate in greater detail), at the surface of carrier material formation drop.The size and the spacing of these drops that form on carrier material 7 downsides also depend primarily on the characteristic of rolling scraper 8, especially depend on its depth of thread or are wound on thickness wiry on the rolling scraper 8.
Between slewing rollers 5 and coiler device, establish dryer section.After slewing rollers 5 were pulled out, it was by this heatable dryer section at carrier material.In this process, make the liquid coating substance drying on the carrier material 7.
As top mentioned, constitute a uniform coating with coating back on carrier material 7 or constitute the drop one by one of inhomogeneous arrangement irrelevant, this depends primarily on the character of coating substance 2 and the surface characteristic of carrier material 7.Under the situation that constitutes drop, the size of drop and their spacing depend primarily on the surface characteristic of coating substance 2 and carrier material 7.
The formation of coating substance 2 drops mainly realizes by the appropriate characteristic on coating substance 2 and carrier material 7 surfaces of selecting on carrier material 7.The key here is that the surface tension of coating substance 2 and carrier material 7 is coordinated with each other in such a way, that is, make the drop that constitutes on carrier material 7 be lower than the superficial density (Flaechendichet) of the coating substance 2 of a regulation at least.
By coating substance 2 of the present invention is a kind of adhesive suspension, and it comprises:
A) adhesive mixture, except that anhydrating, form by following ingredients, 2 to 12% butyl polyacrylates, 1 to 5% copolymer of forming by acrylonitrile and alkyl acrylate, 40 to 95% carboxylic acrylate, 0 to 50% polyvinyl acetate, 0 to 2% defoamer, 0 to 5% is used to adjust the material of pH value, and
