Detection method of fluorine release film

Abstract

The invention relates to the technical field of release force detection, in particular to a fluoride-containing release film detection method which includes the steps: 1 coating detection glue on a release surface of a fluoride-containing release film; 2 drying the fluoride-containing release film coated with the detection glue in the step 1; 3 fitting a PET (polyethylene terephthalate) release film on the glued surface of the dried fluoride-containing release film obtained in the step 2 under 2KG fitting pressure; 4 detecting the release force of a detection tape obtained in the step 3. According to the detection method, based on tests after simulation tests more strict than practical application conditions, the influence of solvents or residual solvents in wet glue on the fluoride-containing release film in the production process can be effectively evaluated, and whether the fluoride-containing release film meets production requirements or not is timely discovered to avoid the problem that the release force of a coated product is increased or the coated product cannot be released.

Description

technical field [0001] The invention relates to the technical field of release force detection, in particular to a detection method for a fluorine release film. Background technique [0002] With the increasing application of temperature-resistant tapes in the electronic market, ordinary acrylic adhesives cannot meet the demand. As a supplier in the electronics industry-the coating industry usually chooses silicon pressure-sensitive adhesives to meet customer needs, and silicon pressure-sensitive adhesives Sensitive glue cannot use silicon release film, so fluorine release film is used more and more, but the detection method of fluorine release film in the prior art cannot guarantee the use of qualified inspection, so there is no problem. The disadvantage of the existing detection method is that in fact, the release force of the fluorine release film is not only the performance of the release film itself, but also the different tapes have a great influence on the release for...

[0002] With the increasing application of temperature-resistant tapes in the electronic market, ordinary acrylic adhesives cannot meet the demand. As a supplier in the electronics industry-the coating industry usually chooses silicon pressure-sensitive adhesives to meet customer needs, and silicon pressure-sensitive adhesives Sensitive glue cannot use silicon release film, so fluorine release film is used more and more, but the detection method of fluorine release film in the prior art cannot guarantee that the inspection is qualified and there is no problem

The disadvantage of the existing detection method is that in fact, the release force of the fluorine release film is not only the performance of the release film itself, but also the different tapes have a great influence on the release force, especially on the fluorine release film. The impact will be even greater when the glue is directly coated, and the incoming inspection is often found to be qualified, but in actual production, the release force becomes heavier or even gradually unable to release, which brings huge losses to production
