Abstract

The invention relates to fluorinated silicate fiber electronic felt and a preparation method thereof. The fluorinated silicate fiber electronic felt is prepared from, by weight, 20-60 parts of PTFE emulsion, 30-60 parts of glass fibers, 0.1-0.8 part of a thickening agent, 0.1-1 part of a coupling agent, 10-30 parts of ceramic powder, 10-30 parts of silica powder and 10-20 parts of soft water. In the preparation process, the glass fibers are put into a dispersion pot, then stirred and conveyed into a pulp storage tank, the other components are put into the pulp storage tank, stirred and then conveyed into a machine chest, the mixture is stirred and then conveyed into a head box, the soft water is added for dilution slushing, then the mixture flows to a net part for prepressing dehydration forming and is compacted by a compacting part and dried by a drying part, and finally the mixture enters a winding part and a cutting part to form the finished felt. The preparation method is simple, the steps are easy to implement, and the prepared fluorinated silicate fiber electronic felt is high in hardness, good in uniformity and high in dielectric constant and heat conductivity; compared with traditional felt, the electronic felt prepared with the preparation method is more suitable for preparing high-frequency copper-clad plates.

Description

technical field [0001] The invention relates to a fluorinated silicate fiber electronic felt and a preparation method thereof, belonging to the technical field of glass fiber felt. Background technique [0002] Glass fiber mat is made of glass fiber strands randomly and evenly distributed into continuous glass fiber paper sheets by papermaking method, and bonded with emulsion. Its main properties are: chemical corrosion resistance, fire prevention, flame retardant, waterproof, aging resistance, weather resistance, insulation and other characteristics. Electrical insulation products, etc. However, with the development of the electronics industry, the requirements for copper-clad laminates and electrical insulation products are getting higher and higher. The texture of the felt is soft, and its physical properties are increasingly unable to meet the requirements, which affects the performance of downstream products and subsequent processing of products. .
