Problems solved by technology

Polyethylene terephthalate (PET) single-sided splicing tape is a tape formed by coating one side of the PET film with a silicone water layer and the other side with a non-silicon coating. The role of release, can withstand high temperature of 200 ℃, but its release performance is poor, and can only be reused 1-2 times
Polyimide (PI) single-sided splicing tape is a tape formed by coating one side of the PI film with a silicone water layer and the other side with a non-silicon coating, which acts as a release through the non-silicon coating , can withstand high temperature of 250 ° C, but its release performance is poor, it can only be used once
The imported splicing tape has good release performance and can be reused 6-10 times, but its price is expensive, which greatly increases the production cost

Embodiment 1

[0021] A strong release splicing adhesive tape, which comprises a layer of PET film 2, on one side of the PET film 2 is coated with a silica gel water layer 1, and on the other side is coated with a fluorine silicon coating 3.

[0022] The production process of the above-mentioned strong release splicing tape is as follows: use an anilox roller coating method, two-roll or three-roll transfer coating method, and apply a fluorine-silicon release agent on one side of the PET film 2 to form a fluorine-silicon coating 3. After standing at room temperature for one day, apply silica gel water on the other side of the PET film 2 by combining an anilox roller and a scraper to form a silica gel water layer 1 . During the preparation process, the cured fluorosilicone coating 3 can also be applied first, followed by the cured silica gel water layer 1, which can be completed online at one time.

[0023] In a preferred embodiment of the present invention, in the process of coating the fluo...

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 [0001] The invention relates to the field of adhesive tapes, in particular to a strong release splicing adhesive tape. Background technique [0002] At present, the splicing tapes used in the manufacture of artificial leather (polyurethane (PU), polyvinyl chloride (PVC), synthetic leather, etc.) and the production of industrial adhesive tapes and self-adhesives and the production of release paper mainly include PET single-sided splicing tape and PI. Single sided splicing tape. Polyethylene terephthalate (PET) single-sided splicing tape is a tape formed by coating one side of the PET film with a silicone water layer and the other side with a non-silicon coating. The release function can withstand the high temperature of 200 ℃, but its release performance is poor, and it can only be reused 1-2 times. Polyimide (PI) single-sided splicing tape is a tape formed by coating one side of the PI film with a silicone water layer and the other side with a non-silicon c...
