Abstract

The invention belongs to the technical field of explosion-proof membranes, and particularly relates to an antistatic anti-aging polyimide explosion-proof membrane which comprises a polyimide layer and a hardened layer. The hardened layer is prepared from the following components in parts by weight: 80 to 100 parts of high-functionality polyurethane acrylate, 15 to 25 parts of an antistatic flexible anti-aging agent, 10 to 20 parts of a reactive diluent, 1 to 3 parts of a photoinitiator, 10 to 20 parts of nanoparticles, 0.05 to 1 part of an anti-fingerprint agent and 80 to 150 parts of a solvent. According to the explosion-proof membrane, the hardened layer is coated on the polyimide layer; polyimide is good in foldability but not good in hardness, and high-functionality polyurethane acrylate in the hardened layer can effectively improve the hardness and abrasion resistance of the hardened layer; and the antistatic flexible anti-aging agent not only can ensure that the hardened layer can be well bent along with the polyimide layer, but also can improve the antistatic performance and aging resistance of the anti-explosion membrane, so that the explosion-proof membrane is high in hardness and foldability, can effectively reduce static electricity generated in the production and use process, and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof membranes, and in particular relates to an antistatic and aging-resistant polyimide explosion-proof membrane. Background technique [0002] Polyimide has excellent mechanical properties, heat resistance, low temperature resistance, flame retardancy, solvent resistance and electrical properties, and can be used as structural composite materials, electrical insulation materials, adhesives and coating materials, and is widely used in electronic micro Electronics, aerospace, optics, electromechanical and other fields. Especially in the field of microelectronics, polyimide is often used as a dielectric layer for interlayer insulation, as a buffer layer to reduce stress, as a protective layer to reduce environmental damage, and as a shielding layer to reduce device errors. Used in various electronic components such as substrates of flexible printed wiring circuits and alignment films for liquid...
