U.S. Patent number 6197397 has disclosed the little formation of duplicating adhesive surface that has the microchannel that is used for the fluid discharging and be used to improve the nail of adhesion characteristic.Such minute-pressure line figure has the microchannel that is used for the fluid discharging and finds time, and can place non-adhesive material therein, thereby promotes the discharging of air, improves the ability of reorientating sheet simultaneously.
Summary of the invention
The present invention is the air that is absorbed in when using adhesive sheet in order to remove, improving releasable and to reorientate the ability of sheet, and outward appearance and bounding force after improving it and using.
The present invention will be by addressing the above problem in conjunction with two types of raceway grooves: when the application sheet, the raceway groove of the first kind can be easy to disappear by pressure, and the raceway groove of second type can not disappear after this sheet is used for some time.
An object of the present invention is to provide a kind of adhesive sheet, wherein form air vent channels with various height and width, so that each air vent channels disappears behind the certain hour of interval, thereby promote the discharge and the bond area that increases sharply of air, to shorten the required time of the bounding force that obtains design, and increase bond area improving the slickness between adhesive surface and the target surface, thereby the figure of air vent channels is not appeared on the front surface of sheet.
Description of drawings
By the description of the following preferred implementation that provides in conjunction with the accompanying drawings, above and other objects of the present invention, characteristics and advantage will become apparent, wherein:
Fig. 1 is the sectional view that illustrates according to the air vent channels of bonding coat of the present invention;
Fig. 2 shows the adhesive surface that has the bonding coat of air vent channels according to of the present invention; And
Fig. 3 shows the adhesive surface of the bonding coat with air vent channels of another embodiment according to the present invention.
Embodiment
The invention provides a kind of adhesive sheet and preparation method thereof, wherein, when on the surface of tackiness agent, forming jog with the qualification air vent channels, formation has the raceway groove of different depths, make some raceway grooves under low pressure can disappear, to increase bond area, therefore can reach the design level of the bounding force of tackiness agent in a short time.In addition, during the application of sheet, convex-concave surface can discharge the air that is absorbed between adhesive surface and the target surface, and raceway groove can disappear in a short time and increase the slickness of adhesive surface, thereby the jog that prevents tackiness agent appears on the surface of sheet.
In the present invention, use conventional texturizing method on release liner, to press the inverse structure corresponding with air vent channels.Release liner makes by using such as polyethylene or polyacrylic thermoplastic resin coated paper, so that it can be by heat or pressure and easily deformable.
Embossing roller is heated to is about the fusing point that is coated in the resin on the release liner, give figure on the release liner of this embossing roller nip part between through embossing roller and rubber rollers.At this moment, the temperature of embossing roller is preferably 90～160 ℃.If the temperature of embossing roller is too low, then, can not extrude required figure because thermoplastic resin lacks flowability.On the contrary, if the temperature of embossing roller is too high, the then undue fusion of resin can not extrude required figure.
Have different heights and width by the raceway groove that release liner is carried out on the adhesive surface that embossing forms, and be connected with each other, thereby the air that is absorbed in when making application sheet can be discharged into the outside of sheet.
About the height of raceway groove, as shown in Figure 1, air vent channels comprises highly to be 10 μ m or littler low raceway groove (L) 11 and to be the high raceway groove (H) 12 of 10～30 μ m highly.Shown in Fig. 2 and 3, these raceway grooves are connected with each other.If the height of air vent channels is 10 μ m or littler, then raceway groove is easy to disappear usually, causes the air discharging relatively poor.But, if the length of raceway groove is reduced to 4mm or littler, then before raceway groove disappears, can obtain emission effect, and raceway groove is easy to disappear, thereby increase the contact area of itself and target surface, this be increase bounding force and prevent that figure from appearing on the surface of sheet desirable.At this moment, for air is discharged into the outside of sheet from low raceway groove (L) 11, low raceway groove (L) 11 should link to each other with high raceway groove (H) 12.Because raceway groove (H) 12 is higher than the height of low raceway groove (L) 11,, thereby can discharge the air of collecting by low raceway groove (L) 11 from the outside of sheet so high raceway groove is not easy disappearance.Hereinafter, at first the low raceway groove (L) 11 of Xiao Shiing is called " first step raceway groove ", and high raceway groove (H) 12 is called " second stage raceway groove ".
But preferred even first step raceway groove also has the height of at least 3 μ m.This is to be generally 1～2 μ m because be coated in the variation in thickness of the tackiness agent on the release liner, therefore need to guarantee that the height of raceway groove is greater than variation, the height of raceway groove also can cause that when it contacts with target surface raceway groove disappears immediately less than 3 μ m, thereby even can not reach the air emission effect in a short time.
Have 2mm or littler pattern pitch if the length of first step raceway groove shortens to excessively, then reduce the contact area with target surface, thereby reduce initial adhesion power, when sheet adheres to curved part, can cause immediately and separate.Therefore, the figure of the preferred first step and second stage raceway groove formation has the pitch of 2mm at least.
In order to realize effective air discharging, except the height of raceway groove, also should consider the width of raceway groove.If the width of raceway groove is bigger, even then raceway groove can not disappear, flow into raceway groove yet after sheet adheres on the target surface, and reduced the contact area with target surface thereby be used as fluidic, reduced bounding force.On the contrary, if the width of raceway groove is less, then raceway groove can be when application sheet and the air that is absorbed in is just blocked before being discharged.Therefore, each first step raceway groove (L) preferably has the width of 10～30 μ m, and each second stage raceway groove (H) preferably has the width of 30～60 μ m.
Wish that first step raceway groove (L) obtains the air emission effect at short notice, still at the outward flange of sheet, its air discharge function reduces.Therefore, first step raceway groove preferably forms with second stage raceway groove (H) and is connected, thereby makes it have length less than 4mm.That is to say that second stage raceway groove preferably has the pattern pitch less than 4mm.
The section of each raceway groove can have the geometrical shape such as rectangle, trilateral, pentagon and U-shape, and first step raceway groove can have the section shape different with second stage raceway groove.Even the section shape of raceway groove is not a rectangle, except the unusual situation of section shape, the variation of raceway groove is by the maximum height decision of bottom width and raceway groove.Therefore, hereinafter, the bottom width in term " width " dactylotome road, the maximum height in term " highly " dactylotome road.
Mode by transfer printing on the surface of tackiness agent forms such figure.Specifically, on the surface of release liner, apply and dry fluid binder with embossing figure.Dry back tackiness agent preferably has the thickness of 20～50 μ m.After this, substrate by rolling or the casting mode with substrate and its adhesion, thereby make the finished product.
To the present invention be described in more detail in conjunction with following embodiment.
After using film, to the evaluation test of its outward appearance
The specimen of preparation 20 * 20cm adheres to the mode of extruding and transparent acrylic panel then.After adhering to one day, according to its condition of surface and the emission behaviour of the air that is absorbed in film is estimated, evaluation result is classified as follows.
| The discharging of air | The film condition of surface | |
| Well | All air that are absorbed in have been discharged | With the naked eye can not identify the figure that the jog on the adhesive surface causes |
| Medium | Give off the air that is absorbed on a small quantity, but do not give off the air that is absorbed in a large number | Find the figure that the jog on the adhesive surface causes slightly |
| Difference | Exist the air that is absorbed in a large number not to be discharged from | With the naked eye can identify the figure that the jog on the adhesive surface causes |
The evaluation of bounding force
Use tension bounding force method of testing to carry out the evaluation of bounding force.According to KS A1107 method of testing, prepare a specimen, and adhere to target object, adhere to and bounding force was estimated in back 20 minutes and 24 hours.
The height of raceway groove and the measurement of width
Release liner is fixed on the flat glass plate, uses SURFTEST 301 surface roughness testers available from Mitutoyo company.When the probe of tester is mobile on release liner, obtain graphic representation, measure the height and the width of embossed lines, be used separately as the height and the width of raceway groove then by this graphic representation.
