Problems solved by technology

[0004] If the treatment agent is not evenly coated on the surface of the glass fiber cloth or the treatment agent cannot penetrate between each monofilament of the glass fiber cloth, it will directly affect the close combination of the glass cloth and the resin, so that the reliability of the formed circuit board substrate sex is severely affected
After the plate is made, its heat resistance and water resistance must be continuously improved, which increases the production cost

Abstract

The invention discloses an electronic grade glass fiber cloth surface treating agent. The surface treating agent comprises the following ingredients, by weight, 0.3%-0.9% of silane coupling agents, 0.3%-0.8% of acidity regulators, and 0.1%-0.5% of surfactants, the balance being deionized water. The glass fiber cloth after treated by the electronic grade glass fiber cloth surface treating agent has good heat resistant performance, good water resistant performance and good wetting property, and has good combination with resins.

Description

technical field [0001] The invention relates to a surface treatment agent, in particular to an electronic-grade glass fiber cloth surface treatment agent applied to printed circuit board insulation reinforcement materials and a method for producing the glass fiber cloth. Background technique [0002] Electronic-grade glass fiber cloth is an inorganic non-metallic material, and the resin is an organic structure. When used as a printed circuit board substrate, the two cannot directly undergo a chemical reaction. In order to effectively combine the two, it is usually necessary to coat the surface of the glass fiber cloth with a Layer treatment agent, the two ends of the treatment agent molecule are inorganic functional groups and organic functional groups, the inorganic functional groups are closely combined with the surface of the glass fiber cloth, and the organic functional groups are reacted and combined with the resin, so that the surface properties of the glass fiber can b...
