Embodiment 1

[0022]Embodiment 1: The present invention provides a PET optical film material with thermal repair ability, including HuntsmanAraldite LY1556 and GY298 epoxy resin, Capcure 3-800 curing agent, polyallylamine, sulfonated polyether ether ketone, sulfur Alcohol-pentaerythritol tetramercapto propionate, Huntsman Araldite LY1556 and GY298 epoxy resin, Capcure 3-800 curing agent, the proportion of thermoplastic resin material is 50-80 parts by weight of epoxy resin, 30-50 parts of polythiol-pentaerythritol Tetramercapto propionate, 20-30 parts of sulfonated polyether ether ketone, 15-25 parts of polyallylamine, 5-8 parts of water, 10-20 parts of curing agent, PTE optical grade film produced by mixing the above ratios , as the temperature continues to rise, the degree of repair of the healing numerical system under the failure load increases, and the strength ranges from 60% to 80% of the initial strength. The healing resin also shows recovery of ductility, and the resin again exhibit...

Embodiment 2

[0023] Example 2: Sulfonated polyether ether ketone is polyether ether ketone synthesized by nucleophilic substitution condensation reaction in the presence of potassium carbonate with difluorobiphenyl and quinone as raw materials. It has high heat resistance, radiation resistance, Chemical resistance, high impact strength, good wear resistance and fatigue resistance, flame retardant, excellent electrical properties, and high permeability.

[0024] In summary, the PTE film produced by mixing the above ratios has high heat resistance, radiation resistance, chemical resistance, high impact strength, good wear resistance and fatigue resistance, flame retardancy, excellent electrical properties, and high permeability. characteristics, with the continuous increase of temperature, the degree of repair of the healing numerical system under the failure load increases, and the strength ranges from 60% to 80% of the initial strength. The healing resin also shows the recovery of ductility...

Abstract

The invention discloses a PET optical film material with thermal repair ability, wherein the PET optical film material comprises epoxy resin, a curing agent, polyallylamine, sulfonated polyetheretherketone and thiol-pentaerythritol tetramercaptopropionate, the epoxy resin is bisphenol A resin, the curing agent is a thiol-terminated curing agent, the PET optical film material comprises the epoxy resin, a Capure 3-800 curing agent and thermoplastic resin and comprises the components in parts by weight: 50 to 80 parts of epoxy resin, 30 to 50 parts of polythiol-pentaerythritol tetramercaptopropionate, 20 to 30 parts of sulfonated polyetheretherketone, 15 to 25 parts of polyallylamine, 5 to 8 parts of water and 10 to 20 parts of the curing agent; the PET optical film produced according to the proportion has the characteristics of high heat-resistant grade, radiation resistance, chemical medicine resistance, high impact strength, good wear resistance and fatigue resistance, flame retardance, excellent electrical property and high permeability, and the healing capacity of the PET optical film is remarkably improved compared with that of a conventional PET optical film.

Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to a PET optical film material with heat recovery capability. Background technique [0002] PET polyester film refers to a film made of polyethylene terephthalate polymer in the polyester family by biaxial stretching. Optical grade PET polyester film has high light transmittance, low haze, high brightness, no yellowing, good adhesion, good flatness, no light and dark lines, high temperature and ultraviolet radiation resistance, good stiffness, anti-burning, not easy Breakage and other characteristics have been widely used in recent years. Especially the indispensable raw and auxiliary materials in the field of LCD production, such as liquid crystal display screens, at least 7 to 8 PET optical films with different functions can be used. Polyester film coated with various functional coatings. Therefore, developing various functional coatings for PET optical films in th...
