Abstract

The invention provides a PFA material and a preparation method thereof, wherein the PFA material comprises a PFA resin, a polysiloxane resin dispersion liquid, a heat-conducting insulating agent and asolvent. Compared with the existing PFA material and the preparation method thereof, the PFA material and the preparation method thereof of the invention have the following characteristics that the existing PFA resin is used as the matrix resin, and the dispersity and the electric field uniformity can be ensured at the same time by adding polysiloxane, so that the technical problem that the effective breakdown field intensity of the PFA material is greatly reduced due to the non-uniform structure and the non-uniform electric field of the existing PFA material is solved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a PFA material and a preparation method thereof. Background technique [0002] In the manufacturing process of Thin film transistor liquid crystal display (TFT-LCD), static electricity is continuously generated due to the substrate being constantly moved, rubbed, adsorbed, heated, pressurized, separated, desorbed, cooled, etc. When accumulated to a certain extent, electrostatic discharge (ESD) phenomenon will occur, which will greatly affect the quality of the product. With the improvement of panel resolution and higher level of circuit integration, the relative metal interconnection line width is getting smaller and smaller, and it is more and more sensitive to the influence of ESD. [0003] Currently common panel structures, in addition to Indium tin oxide (ITO) and conductive metal traces on the array substrate side, mainly include three types of materials: frame ...
