Problems solved by technology

[0004] 5G communication materials require materials with very low dielectric constant and dielectric loss. Today, most of the materials used in 4G communication are polytetrafluoroethylene. However, polytetrafluoroethylene has poor compatibility with materials, and only It is hydrophobic and has almost no self-cleaning performance on organic pollutants such as oil droplets, which hinders its application in 5G communication terminals
And the glass transition temperature of polytetrafluoroethylene is low, because high-power communication transmission will generate a lot of heat, so the stability of polytetrafluoroethylene also has defects

Abstract

The invention provides reactive fluorosilicone resin as well as a preparation method and application thereof. The reactive fluorosilicone resin is used as an additive, so that an added material has low dielectric constant, self-cleaning performance and excellent adhesion performance.

Description

technical field [0001] The invention belongs to the field of functional resins, and relates to a reactive fluorosilicone resin, a polymeric fluorosilicone resin and a preparation method and application thereof. Background technique [0002] Self-cleaning mainly includes two aspects: one is the super-hydrophobic self-cleaning coating that removes surface pollutants by means of the scouring of water or oil by super-hydrophobic materials or super-oleophobic materials; Hydrophobic or superoleophobic self-cleaning coatings. The self-cleaning effect of the former is mainly manifested in the self-cleaning function of dust, mud and other inorganic stains endowed by the special wettability of the super-hydrophobic or super-oleophobic coating, and its self-cleaning function often needs to be washed by rainwater and a certain amount of time. to achieve the tilt angle. When water droplets or oil droplets fall on an inclined super-hydrophobic or super-oleophobic surface, they are easy ...
