Problems solved by technology

When there is a large amount of solvent in the coating slurry or there is still good fluidity, if the curling direction of the thermal peeling tape cannot be well controlled during the foaming and shedding process, it is easy to cause slurry pollution on the surface of the tape , Adhesive damage normal coating

Embodiment Construction

[0014] The following examples are further explained to the present invention.

[0015] A method of making a hot -stripping acrylic acryl -sensitive adhesive belt, the preparation steps are:

[0016] Select 100 parts of acrylic polymers and 15-40 parts of expansion microspheres evenly, add 0.01-2 parts of isocyanate couplet, coated on the substrate, coated with the thickness of the drying glue to 30-60um, and then at 60-90 ℃ Dry to obtain a thermal peeling pressure-sensitive adhesive band, and then the prepared thermal separation-sensitive glue sticky band is fitted with 25-75um lyric membrane, which is made of thermal peeling acrylic compressive adhesive band.

[0017] The acrylate polymer has 60-140 parts of acrylic, 50-100 parts of acrylic, 0.5-1.5 parts of puppet nitrogen dilite, 5-15 parts of acrylic hydroxyl ethyl, 5-10 methyl methyl-based methylsPacide, 5-10 parts of acrylic, 0.1-2 parts of N-hydroxymethylene acrylamide, and ethyl acetate are 250-400 copies.

Abstract

The invention relates to a production method of a thermal-stripping acrylate pressure-sensitive adhesive tape. The production method comprises the following steps: 1) selecting and uniformly mixing 100 parts of an acrylate polymer and 15-40 parts of expansive microspheres, adding 0.01-2 parts of an isocyanate crosslinking agent, coating a substrate with the mixture with thickness of coated dry glue being 30-60 [mu]m; 2) drying the glue coating at 60-90 DEG C to obtain a thermal-stripping pressure-sensitive adhesive tape; and 3) laminating the thermal-stripping pressure-sensitive adhesive tape onto a release film being 25-75 [mu]m to prepare the thermal-stripping acrylate pressure-sensitive adhesive tape. The pressure-sensitive adhesive tape is easy to control in winding direction when being foamed at 120 DEG C. The tape can be wound tidily and regularly.

Description

Technical field [0001] The present invention is a method of making a pressure -sensitive glue technology, which involves a method of making a thermal acrylate pressure -sensitive adhesive band. Background technique [0002] In recent years, as thermal stripping tape is widely used in electronic components, it is gradually applied to the coating or spraying industry.During the online coating process, the hot peeling tape must not only play a good protective role on the protected base surface, but also can automatically fall off when passing through heating.Non -protective coating has no adverse damage. [0003] At present, the thermal abolition -sensitive adhesive band is mainly aimed at the reduction or elimination of its adhesion after heating foam.However, there are few research on the curling direction of the substrate during the heating of thermal peeling tape.Especially when the foam glue belt is protected by the adhesive, and the surface of the substrate needs to have a cer...
