Embodiment Construction

[0022] The PET compound of heat-resistant aging insulating film of the present invention, raw material composition comprises 100 parts of PET resin chips, 0.1~1.0 parts of nano particle nucleating agent, 10~15 parts of ultrafine nylon powder, 0.1~ 1.0 parts of ammonium polyphosphate, 1 to 10 parts of pentaerythritol and 1 to 6 parts of triphenyl phosphite, the nanoparticle nucleating agent of the present invention is nano inorganic particles treated with silane coupling agent, and the nano inorganic particles are processed by silane coupling The joint agent is processed into a nano-particle nucleating agent to improve the fraction of the nano-inorganic particles in the PET matrix. At the same time, mixing with ammonium polyphosphate, pentaerythritol, and triphenyl phosphite can further disperse the nano-inorganic particles, and has the ability to PET insulating film has better flame retardant effect. The ultrafine nylon powder of the present invention is nylon powder of 600~20...

Abstract

The invention relates to a PET compound of a heat and ageing resistant insulation film. Raw materials of the PET compound comprise, by mass, 100 parts of PET resin slices, 0.1-1.0 part of a nanoparticle nucleating agent, 10-15 parts of ultrafine nylon powder, 0.1-1.0 part of ammonium polyphosphate, 1-10 parts of pentaerythritol and 1-6 parts of triphenyl phosphite, wherein the nanoparticle nucleating agent is a silane coupling agent with the content of 4-6%, the silane coupling agent comprises a fluorine-containing silane coupling agent and an active silane coupling agent according to a mass part ratio of 0.6-1.2:1, and the ultrafine nylon powder is 600-2000 mesh nylon powder. The method has simple process flow, the dispersibility of the nanometer inorganic particle nucleating agent is easy to regulate, and the PET compound has excellent high temperature and ageing resistance.

Description

technical field [0001] The invention relates to a PET composite of a heat-resistant aging insulating film and a preparation method thereof, belonging to the technical field of polyester film manufacture. Background technique [0002] PET (polyethylene terephthalate) is a crystalline polymer with excellent creep resistance, fatigue resistance, friction resistance, wear resistance, chemical resistance, dimensional stability, gas and Low water vapor permeability, excellent electrical insulation, widely used in automotive, electrical and electronic, insulating materials and other fields. Biaxially oriented PET film has excellent physical and mechanical properties in a wide temperature range. It can be used at 120°C for a long time, and can withstand high temperatures of 150°C for short-term use. It is widely used in plate making, packaging, optical, and insulating films. In recent years, along with the development of electrical or electronic components, capacitor films or motor...
