Description

Technical field: [0001] The invention relates to the technical field related to communication materials, in particular to a PBT material coating and a preparation method. Background technique: [0002] PBT is a milky white translucent to opaque, crystalline thermoplastic polyester. It has high heat resistance, toughness, fatigue resistance, self-lubrication, low friction coefficient, weather resistance, low water absorption, only 0.1%, and still maintains various physical properties (including electrical properties) and electrical insulation in a humid environment. However, volume resistance and dielectric loss are large. Resistant to hot water, alkalis, acids, oils, but easily corroded by halogenated hydrocarbons, poor hydrolysis resistance, rapid crystallization at low temperature, good formability. [0003] Polybutylene terephthalate (PBT) is a kind of thermoplastic saturated polyester and an engineering plastic with strong crystallinity. PBT, PA, POM and MPPO are know...
