Embodiment
[0027] Such as figure 1 As shown, an embodiment of the ultra-thin buffer foam tape of the present invention, the ultra-thin buffer foam tape includes an ultra-thin buffer foam layer 1 , a PET double-sided tape 2 and an embossed release material layer 3 sequentially compounded. Wherein, the PET double-sided adhesive tape 2 is formed by a PET substrate 21 and an acrylic glue layer 22 coated on both surfaces thereof. The overall thickness of the ultra-thin buffer foam tape is 0.1-0.3mm, the thickness of the ultra-thin buffer foam layer 1 is 0.05-0.2mm, and the thickness of the PET double-sided adhesive tape is 5-20um.
[0028] The preparation method of the ultra-thin buffer foam tape is: preparing a PET double-sided tape and an ultra-thin buffer foam layer substrate, and sticking one side of the PET double-sided tape tightly on the ultra-thin buffer foam layer substrate; The other side of the PET double-sided tape is compounded with a layer of embossed release material. The ult...

Abstract
The invention discloses a production method of ultrathin buffer foam tape.The production method includes: preparing PET double-sided tape and ultrathin buffer foam layer base material, and tightly adhering one side of the PET double-sided tape to the ultrathin buffer foam layer; compositing an embossed release material layer on the other side of the PET double-sided tape.A production method of the ultrathin buffer foam layer specifically includes: cutting thick PE foam with high foaming ratio into foam sheets of 0.3-0.5mm, and performing hot-press forming on the foam sheets to obtain the ultrathin buffer foam layer; or performing hot-press forming on PU foam or melamine foam to obtain the ultrathin buffer foam layer, wherein the temperature of the hot-press forming is 180-220 DEG C, the pressure of the hot-press forming is 3-8kg/cm<2>, and the speed of the hot-press forming is 8-20m/minute.The ultrathin buffer foam tape produced by the hot-press process has functions of absorbing shock and sounds and automatically removing bubbles.
Description
technical field [0001] The invention belongs to the field of electronic application adhesive tapes, in particular to an ultra-thin buffer foam adhesive tape and a preparation method thereof. Background technique [0002] Buffer foam tape is a material with shock absorption, sound absorption and sealing effect, which is made of foam material as the base material through composite release materials. It is widely used in electronic and electrical products, mechanical parts, various small household appliances, and mobile phone accessories. , industrial instruments, computers and peripheral equipment, auto parts, audio-visual equipment, toys, cosmetics, craft gifts, medical instruments, electric tools, office stationery, shelf display, home decoration, acrylic glass, ceramic products, etc. insulation, pasting, sealing, Anti-slip and shock-absorbing cushioning. [0003] Traditional PE, PU and melamine foams have good cushioning and sound-absorbing properties, but due to the limit...
