Abstract

The invention belongs to the technical field of electronic glass fiber cloth, and particularly relates to a slurry for electronic-grade glass fiber cloth and a preparation method thereof. The raw materials of the slurry for electronic-grade glass fiber cloth include the following components: the raw materials of the slurry include 0.5-2% of polyvinyl alcohol, 0.05-0.1% of water-based rosin resin, 0.01-0.05% of water-based phenolic resin, and 0.1-1.0% of gum yarrow, 0.2-2% of stabilizer, 0.1-0.8% of lubricant, and the rest are deionized water. The preparation method is as follows: firstly, adding polyvinyl alcohol, water-based phenolic resin, stabilizer and some lubricants into water, mixing and stirring; then adding water-based rosin resin and tragacanth gum, stirring; finally adding remaining lubricant and stirring. The sizing provided by the invention has good adhesion and strong abrasion resistance, does not need secondary sizing before weaving, can protect the abrasion during the preparation of warp yarns, reduces the generation of broken silk and hairiness, and is easy to desizing.

Description

technical field [0001] The invention belongs to the technical field of electronic glass fiber cloth, and particularly relates to a slurry for electronic-grade glass fiber cloth and a preparation method thereof. Background technique [0002] Conductive fibers composited with resins such as carbon fiber, stainless steel, nickel fiber, etc. have been practically used, but they have not yet entered the stage of large-scale application due to price and performance constraints. Carbon black has excellent performance, but the price is relatively high; the ceramic matrix is ​​also limited in its application due to its brittleness. Carbon fiber has high temperature resistance, radiation resistance, good electrical conductivity, low density, and high specific strength, but the surface of carbon fiber is inert. Poor matrix adhesion. [0003] Glass fiber itself is an excellent inorganic non-metallic material with high mechanical properties, low price and excellent electrical insulation...
