Description
Technical field
This utility model belongs to electronic application adhesive tape area, particularly relates to a kind of ultra-thin buffering foam tape.
Background technology
Buffering foam tape is the material with damping, sound-absorbing, sealing function being prepared from for base material by compound separated type material with foam material, be widely used in electric equipment products, component of machine, all kinds of small household appliances, Cellphone Accessories, industrial instrument, computer and perimeter equipment, auto parts machinery, audio-visual equipment, toy, cosmetics, process gift, Medical Instruments, electric tool, office stationary, shelf display, home decoration, acrylic glass, ceramic etc. insulation, paste, seal, anti-skidding and buffer shockproof.
Traditional PE, PU and tripolycyanamide foam have good resiliency and sound absorption qualities, but due to the restriction of processing technique, it is impossible to obtain high foamability and the ultra-thin buffering foamed cotton material bed of material.Traditional processing technique can only obtain the buffering foamed cotton material bed of material of more than 1mm.But, in terms of electronic product bumper and absorbing shock, the particularly damping bottom electronic display, need the fabulous ultra-thin cushioning materials of high foamability, high-flexibility and resiliency to eliminate the Newton's ring produced between touch module because section difference.It addition, easily produce bubble in electronic display produces installation process, affect product quality, prior art can only waste time and energy by manually getting rid of bubble.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of ultra-thin while there is damping, sound-absorbing and automatically get rid of the ultra-thin buffering foam tape of bubble function.
For solving above-mentioned technical problem, the technical scheme that the utility model proposes is:
A kind of ultra-thin buffering foam tape, including the ultra-thin buffering foamed cotton layer base material made by thermocompression forming, a surface of described ultra-thin buffering foamed cotton layer is compounded with one layer of PET two-sided tape, and the another side of described PET two-sided tape is compounded with embossing release material layer；Described ultra-thin buffering foamed cotton layer is the ultra-thin buffering foamed cotton layer prepared through cutting and thermocompression forming by the thicker PE foam of high foamability；Or described ultra-thin buffering foamed cotton layer is the ultra-thin buffering foamed cotton layer prepared through thermocompression forming by PU foam or tripolycyanamide foam.
Further improvement as to technique scheme:
Preferably, the integral thickness of described ultra-thin buffering foam tape is 0.1～0.3mm.
Preferably, the thickness of described ultra-thin buffering foamed cotton layer is 0.05～0.2mm.
Preferably, the thickness of described PET two-sided tape is 5-20um.
Preferably, described embossing release material surface has netted texture projection, and the reticule of described netted texture is deep mixed.
Compared with prior art, the utility model has the advantage of:
Ultra-thin buffering foam tape of the present utility model, break traditional high magnification, low-density foam can not be prepared as the technology barriers of ultrathin products, hot pressing mode is used to make ultra-thin by thicker buffering foam material, high magnification, low-density buffering foamed cotton layer, again with PET adhesive tape layer and have deep mixed embossing embossing release material layer be combined, obtained ultra-thin buffering foam tape has good resiliency, it is provided simultaneously with energy damping, sound-absorbing, automatically the advantage getting rid of bubble, can be used for touch screen damping, eliminate Newton's ring, it is easy to large area laminating, it is automatically drained out bubble and can save substantial amounts of manpower and materials, cost-effective.

Detailed description of the invention
For the ease of understanding this utility model, below in conjunction with Figure of description and preferred embodiment, this utility model is made more comprehensively, described meticulously, but protection domain of the present utility model is not limited to embodiment in detail below.
Embodiment:
As it is shown in figure 1, a kind of ultra-thin buffering foam tape embodiment of the present utility model, this ultra-thin buffering foam tape includes ultra-thin buffering foamed cotton layer 1, PET two-sided tape 2 and the embossing release material layer 3 being combined successively.Wherein, PET two-sided tape 2 is formed by PET base material 21 and the acrylate glue water layer 22 that is coated on two surface.The integral thickness of this ultra-thin buffering foam tape is 0.1～0.3mm, and the thickness of ultra-thin buffering foamed cotton layer 1 is 0.05～0.2mm, and the thickness of PET two-sided tape is 5-20um.
The preparation method of this ultra-thin buffering foam tape is: prepares PET two-sided tape and ultra-thin buffering foamed cotton layer base material, and the one side of PET two-sided tape is closely sticked on this ultra-thin buffering foamed cotton layer base material；The another side of PET two-sided tape is combined a lamination stricture of vagina separated type material layer.This ultra-thin buffering foamed cotton layer uses the padded coamings such as PE foam, PU foam or tripolycyanamide foam to obtain through hot pressing.
When using PE foam as buffering foamed cotton layer, it is that the PE foam by 20～40 times of thicker expansion ratios becomes the relatively thin PE foam of 0.3～0.5mm through cutting, then makes the low-density that thickness is 0.05～0.2mm, high buffering, the ultra-thin buffering foamed cotton layer of high-foaming through hot pressing.
When using PU foam or tripolycyanamide foam as buffering foamed cotton layer, it is directly by 5～50 kg/m3PU foam or tripolycyanamide foam obtain, through thermocompression forming, the ultra-thin buffering foamed cotton layer that thickness is 0.05～0.2mm.When these buffering foam materials are carried out hot pressing, hot pressing temperature preferably used is 180 ° DEG C～220 ° DEG C, and hot pressing pressure is 3～8 kg/cm2, hot pressing speed is 8～20 ms/min.Traditional handicraft when preparation buffering foamed cotton layer often its thickness can only achieve more than 1mm, and use heat pressing process can obtain thinner buffering foamed cotton layer, its thickness typically can reach 0.05～0.2mm, significantly expands the range of application of obtained buffering foam tape.It addition, the embossing release material surface in this buffering foam tape has netted texture projection, the reticule of this netted texture is deep mixed.Netted texture deep mixed on embossing release material layer makes to buffer foam tape and has good automatic exhaust performance.
Ultra-thin buffering foam tape of the present utility model uses high magnification, low-density buffering foam material to be prepared as ultra-thin buffering foamed cotton layer through hot pressing, then be compounded to form a kind of ultra-thin buffering foam tape with PET double faced adhesive tape belt and embossing release material layer.Owing to embossing release material surface has deep mixed netted texture projection, therefore it has automatic ventilating function, can be automatically drained out bubble, saves substantial amounts of manpower and materials.The preparation method of this buffering foam tape has broken traditional high magnification, low-density foam can not make the technology barriers of ultrathin products.This buffering foam tape has ultra-thin, damping, sound-absorbing, automatically gets rid of the advantage of bubble, can be used for touch screen damping, eliminates Newton's ring, it is simple to large area is fitted.
