Abstract
The invention relates to the field of adhesive tape, and specifically provides a strong release-type connecting adhesive tape. The connecting adhesive tape comprises a layer of PET film, which is characterized in that one surface of the PET film is coated with a silica gel-water layer, and the other surface of the PET film is coated with a silicon fluoride coating. The connecting adhesive tape provided by the invention has good adhesive property on release paper with low surface energy, high temperature resistance, and strong release characteristics on the back, and can be reused for 8-10 times. The connecting adhesive tape provided by the invention has large shearing force in high temperature bonding, and will not break paper after connection. The release-type coating has extremely low mobility, good strong release type and solvent resistance. The connecting adhesive tape provided by the invention is mainly used for production of artificial leather and industrial adhesive tape.
Description
Technical field
The present invention relates to the adhesive tape field, relate in particular to a kind of strong release connecting tape.
Background technology
The connecting tape that is used for leatheroid (urethane (PU), SE (PVC), synthetic leather etc.) manufacturing and the production of industrial sealing tape non-setting adhesive and separate-type paper production at present mainly contains PET single face connecting tape and PI single face connecting tape.Polyethylene terephthalate (PET) single face connecting tape is to coat the silica gel water layer in the one side of PET film; Another side is coated the adhesive tape that non-silicon coating forms; It is to play release effect through non-silicon coating; Can tolerate 200 ℃ high temperature, but its release performance is relatively poor, and can only reuses 1-2 time.Polyimide (PI) single face connecting tape then is to coat the silica gel water layer in the one side of PI film; Another side is coated the adhesive tape that non-silicon coating forms, and it is to play release effect through non-silicon coating, can tolerate 250 ℃ high temperature; But its release performance is poor, can only use 1 time.The connecting tape of import has good release performance, and reusable 6-10 time, but it costs an arm and a leg, and increases production cost greatly.
Summary of the invention
In view of this, be necessary in fact to provide that a kind of cost is low, release performance good, tack is good, reusable 8-10 time strong release connecting tape.
A kind of strong release connecting tape, said connecting tape comprises one deck PET film, scribbles the silica gel water layer in the one side of said PET film, scribbles the fluorine silicon coating at the another side of said PET film.
Preferably, said fluorine silicon coating is to be made by hydroxy-end capped methyl (3,3,3-trifluoro propyl) the siloxanes FSR-2000 that gathers.
Preferably, said PET film is that thickness is the PET electronic-grade light film of 25 μ m-36 μ m.
Preferably, the thinner of said fluorine silicon parting agent is a toluene.
Preferably, said silica gel water is toluene, YLENE or 120# non-leaded gasoline.
The preparation method of above-mentioned strong release connecting tape, it may further comprise the steps:
Coat fluorine silicon parting agent in the one side of PET film; Coat silica gel water at PET film another side.
Preferably, during coating fluorine silicon parting agent, adopt the mode of anilox roll coating method, two rollers or three roller transfer coating to be coated with.
Preferably, during silicon-coated glue, adopt anilox roll and scraper combination to be coated with.
Compared with prior art, connecting tape of the present invention has following beneficial effect:
1) connecting tape of the present invention has preferably " function of plugging into " (adhesiveproperties) to the low separate-type paper of surface energy, can be high temperature resistant, and its back side also has strong release characteristic, reusable 8-10 time.
2) connecting tape of the present invention has bigger shearing force when high temperature bonding, and paper can not break after plugging into.
3) other connecting tape of the present invention selects for use high quality raw material and curing process outstanding, and release coating transport property is extremely low, has good strong release and anti-solvent.
Connecting tape of the present invention mainly works to plug into, engage the release high temperature of the separated type material and the back side and sticks with paste body, melt and glue; Mainly in the process of leatheroid manufacturing (PU, PVC, synthetic leather etc.) and industrial sealing tape non-setting adhesive production use, use especially being used on the leatheroid manufacture more.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of strong release connecting tape, it comprises one deck PET film 2, scribbles silica gel water layer 1 in the one side of this PET film 2, another side scribbles fluorine silicon coating 3.
The production technique of above-mentioned strong release connecting tape is following: use the mode of anilox roll coating method, two rollers or three roller transfer coating, coat fluorine silicon parting agent in the one side of PET film 2, form fluorine silicon coating 3.After normal temperature is placed one day, use anilox roll and scraper bonded mode to coat silica gel water at PET film 2 another sides, form silica gel water layer 1.In the preparation process, fluorine silicon coating 3 is solidified in coating earlier, then is coated with solidification of silicon glue layer 1, once online completion.
In preferred embodiments of the present invention, in the process of coating fluorine silicon parting agent, can the glue spread of fluorine silicon parting agent be controlled at 1g/m
2, being coated with the relief adhesive tape through the long baking oven of 15m, this baking oven is divided into three sections; First section temperature range is 90-100 ℃; Second section temperature range is 110-120 ℃, and the 3rd section temperature range is 110-100 ℃, and adhesive tape was controlled at 1-2 minute through the time of baking oven.In another preferred embodiments of the present invention, during the coating of silica gel water, its glue spread is controlled at 30g/m
2Be coated with the relief adhesive tape through the long baking oven of 24m, this baking oven is divided into four sections, and first section temperature range is 90-100 ℃; Second section temperature range is 120-140 ℃; The 3rd section temperature range is 160-170 ℃, and the 4th section temperature range is 120-110 ℃, and adhesive tape was controlled at 1-2 minute through the time of baking oven.
Above-mentioned PET film preferred thickness is the PET electronic-grade light film of 25 μ m-36 μ m, and this PET film can anti-150 ℃ high temperature, and shrinkability at high temperature changes small.Preferred hydroxy-end capped methyl (3,3, the 3-trifluoro propyl) siloxanes (FSR-2000) that gathers of fluorine silicon parting agent, its sticking power is good, state of cure is high, solvent resistance.The preferred toluene of thinner of this fluorine silicon parting agent.In a preferred embodiments of the present invention, preferred YLENE of silica gel water or 120# non-leaded gasoline more preferably are toluene.
