Description
Technical field
The present invention relates to adhering technique field, relate in particular to a kind of contact adhesive composition,
The contact adhesive of infrared transparent black can be prepared from it.The invention still further relates to comprise described pressure
The adhesive tape of sensitive adhesive, particularly relates to infrared transparent black belt.Moreover, it relates to
Described contact adhesive composition and the preparation method of described adhesive tape and purposes, such as it is at photoelectricity
Purposes in sub-field.
Background technology
Optical sensing devices or work in specific discontinuous wave-length coverage, or its work
Scope extends in broader electromagnetic radiation wavelength scope.In order to this sensing device is integrated into
For in this structure designed, the special material that uses in needing compatible sensing device working range and
Manufacturing technology.Described sensing device is made up of emitter and receptor mostly, and they are respectively in limit
Launch in fixed wave-length coverage or receive.
In Video Supervision Technique, generally using CCTV or network video camera, they should be
In the daytime reliable high quality graphic is provided with night to observer or monitoring of software.Additionally, these
Video monitoring equipment should be not seen by the public, or should be at least unremarkable, and
And should be protected by exempting from destruction.These three requires by being integrated in phase in video camera dexterously
The sensing device answered realizes.Adusk night vision function by launch such as at 850nm or
Near-infrared radiation under 940nm wavelength completes, and all objects all reflect near-infrared radiation, and
Can be detected by sensing device.In order to hide monitoring device, shell must be covered with black layer,
This black layer makes visible ray and the infrared spoke of the most (" The more the better ") of q.s
Penetrate and pass through.
In order to detect vandalism, it is possible to use by infrarede emitting diode and infrared receiver two
The diastimeter of pole pipe composition, it is also referred to as proximity transducer or proximity test device, Qi Zhonghong
UV light-emitting diode and infrared receiving diode are placed at different angles.The most less desirable thing
Body enters the region of closely this sensor, and infrarede emitting diode is just launched by this object
Near-infrared radiation reflexes at infrared receiving diode, and therefore triggers noiseless destruction alarm.
This object can be to monitor the sack being bonded on video camera to destroy or be sprayed on device
Color.Because this security mechanism should activate in the case of the other side is careless, so being this
Required sensing device must unobtrusively be integrated on device.The position of tamper-proof sensing device
Should not known to opponent, thus opponent can not take targetedly counter-measure with destroy should
Security mechanism, or will not be by vigilance to take described counter-measure to destroy described device.Logical
Often, the outward appearance of this video camera is black, it is therefore desirable to a kind of in visible-range almost
Light tight but almost complete printing opacity near infrared range light filter.Additionally, this light filter
Should structurally and can be simply integrated in Technology in described device, such as
In watch-dog.Sometimes the functional requirement visual clarity of these devices is 5 to 20%.
So far, known following kind of light filter, i.e. by the coating infrared transparent black
It is coated on visible ray and the plate of infrared transparent or thin film manufacture.Because such offer light
The colored pigment learning function is coarse grained mostly, so coating known to these must pass through silk
Wire mark brush coats with thick-layer.This silk-screen printing technique is complicated and expensive, and coating quality is low
Bad.Especially, the thickness deviation of these coatings is very poor, and therefore uniformity is the most very poor, can
The functional fault thus making sensor can be caused.
By manufacturing intrinsic black, infrared transparent film provides another possibility, Qi Zhongyan
Material is evenly distributed in film resin itself.But the shortcoming of this method is, the minimum thickness of film is non-
Chang great.By improving melt flow index, high shear force can be obtained in the hybrid case, this
It is of value to and pigment is evenly distributed in resin, thus obtain highly uniform film.But, one
Denier is mixed in film resin, pigment or the dyestuff of high concentration just due to face in the orientation process of film
What material caused closes on film tear and forms little defect.Further, since fracture tensile strength is very
Low, the stability of these films is the most unsatisfactory.Even if in order to also obtain in the case of thin film
Obtain high black level value, it is necessary to using the resin that the highest pigment is filled, this can make film very rapid wear
Bad and unstable.This high filling film lacks cohesiveness, by during the subsequent applications of adhesive tape
Cause tear.Due to reason as mentioned above, such film be currently do not have commercially available.
This high thickness makes membrane rigidity very strong, causes the flexible loss of adhesive tape, and therefore adhesive tape can not be fitted
Answer curved surface, and adhesive tape slowly comes off due to the permanent strain of rigid film.This rigid film
Rough surface can not be adapted to, even do not adapt to be partially coated with or be printed with some dyestuffs
Flat surfaces.
Known in the art, any particulate additive such as pigment of high-load can significantly drop
Low or destroy peel adhesion completely, additionally pigment generally with many cross-linking agent not phase of binding agent
Holding, therefore those of ordinary skill in the art the most not will recognize that the base material doping merit making normal hyaline
Can property, infrared transparent dark colored binder.Additionally, this functional binding agent construction cycle
Length and cost are high.Especially, the most challenging is how to obtain enough uniformities, this
Being because compared with binding agent, pigment has higher density, and the most heavier pigment can settle
Bottom to container.The particularly low viscosity of binding agent is unsuitable for required pigment is dispersed in bonding
In agent, such as in PET or PMMA resin melt.

Table 2: the measurement result of sample S1-S5
By upper table it can be seen that be used for the infrared transparent black matrixes of comparative example S2, derive from
The PMMA film of Evonik has too low tensile break strength (57N/mm2), and also tool
There is the excessive thickness of 75 μm.After the adhesive phase of coating 50 μ m-thick, total tape thickness is
125 μm, it is the thickest and cannot be used in most design gaps.It addition, the thickest adhesive tape is flexible
Not, thus be not easy to adhere to coarse or curved surface.Due to two reasons as above,
The inapplicable required application of comparative example S2.About comparative example S3, use the PET of 23 thin μm
Base material, prints the black paint of infrared transparent thereon, and this tape thickness is thin, and has good
Tensile break strength, but lack of homogeneity, and need other expensive treatment step.And contaminate
