Problems solved by technology

[0002] Protective films are often used in hardware, optoelectronics and printing industries. In optoelectronic devices, especially solar devices, protective films are often required to have excellent heat resistance. Compared with commonly used polymethyl methacrylate, polystyrene and Polycarbonate and silicone rubber adhesives have better heat resistance. The prior art CN102757742A discloses a heat-conducting film graphite material, including polyester or polypropylene base film and acrylic glue or silicone glue, which is still stable at 180°C. Good properties, but noticeable warping and debonding if higher temperatures are required

Embodiment

[0025] A heat-resistant silica gel protective film includes a carrier layer and a silica gel layer.

[0026] The carrier layer includes a polyimide layer. In embodiments where there is no transparency requirement, the carrier layer may be composed of a single polyimide layer. In some embodiments, the carrier layer also includes an anti-PET layer. , One or more of electrostatic layer, thermal conductive layer and conductive layer, polyimide layer, antistatic layer, thermal conductive layer or conductive layer can be coated on the polyimide layer by coating, The thickness of the carrier layer is 35-75um.

[0027] The silica gel layer includes high molecular weight vinyl silicone resin, phenyl vinyl silicone oil, phenyl hydrogen-containing silicone crosslinking agent, silicone catalyst, nano ceria, solvent and adjuvant, and the thickness of the silica gel layer is 50-150um. In actual production, the thickness of the silica gel layer is generally 25-45um. In this thickness range, both...

Abstract

The invention relates to a heat-resistant silicone protective film. The heat-resistant silicone protective film comprises a carrier layer and a silicone layer, wherein the carrier layer comprises a polyimide layer; and the silicone layer comprises nano cerium dioxide. The regularity of the silicone layer structure is obviously increased, the heat resistance and heat-conducting property of the protective film disclosed by the invention are increased, the heat-resistant temperature reaches 350 DEG C, and the silicone protective film has excellent application prospects.

Description

Technical field [0001] The invention relates to the technical field of membrane materials, and more specifically, to a heat-resistant silica gel protective film. Background technique [0002] Protective films are often used in the hardware, optoelectronics and printing industries. In optoelectronic devices, especially the protective films used in solar devices, they are often required to have excellent heat resistance. Compared with the commonly used polymethylmethacrylate, polystyrene and Polycarbonate and silicone rubber adhesives have better heat resistance. The prior art CN102757742A discloses a thermal conductive film graphite material, which includes polyester or polypropylene substrate film and acrylic glue or silicone glue, which can still be maintained at 180°C. It has good performance, but if higher temperature is required, obvious deformation and degumming will occur. [0003] In order to increase the heat resistance of the silica gel protective film, heat-resistant age...
