Abstract

The invention discloses a preparation method of a high-temperature-resistant grid acrylic pressure-sensitive adhesive tape, which is characterized in that: 20-90 parts by mass of silicone rubber, 10-80 parts by mass of silicone resin, 1-3 parts by mass of catalyst and 100-500 parts by mass of solvent are uniformly mixed to prepare an organic silicone resin coating material; a PET precoating film silicone coated with a thin film surface treatment agent is coated by the organic silicon resin coating material, after pre-drying, a high-temperature-resistant grid PET release film is prepared, and then the high-temperature-resistant grid PET release film is coated with acrylic pressure sensitive adhesive, after pre-drying, the high-temperature-resistant grid PET release film is bonded with cloth-based materials such as thin films such as polyester, polypropylene, polycarbonate, polyimide thin film or cotton cloth, non-woven cloth, glass cloth and the like, and then rolled up to prepare the high-temperature-resistant grid acrylic pressure sensitive adhesive tape. The high-temperature-resistant grid acrylic pressure-sensitive adhesive tape prepared by the invention greatly improves the temperature resistance, does not melt when the use temperature reaches 200 DEG C, keeps the grid structure undeformed, and ensures the surface exhaust performance of the pressure-sensitive adhesive tape.

Description

technical field [0001] The invention belongs to pressure-sensitive adhesive tapes, and relates to a preparation method of high-temperature-resistant grid acrylic pressure-sensitive adhesive tapes. The high-temperature-resistant grid acrylic pressure-sensitive adhesive tape prepared by the invention is suitable for semi-finished products of high-temperature printing labels and high-temperature foam adhesive tapes. Background technique [0002] The existing grid acrylic pressure-sensitive adhesive tape is prepared by coating acrylic pressure-sensitive adhesive on grid release film or release paper, and then laminating films such as polyester, polypropylene, and polycarbonate. The surface of the obtained adhesive tape has a regular grid shape, and it is not easy to generate air bubbles after being attached to the flat and smooth surface of the pasted object, and the adhesive tape has an excellent exhaust function. The above-mentioned grid release film or release paper usually ...
