Problems solved by technology

[0006] However, the coupling agent hydrolysis process involved in the above-mentioned patent belongs to the conventional hydrolysis method of the coupling agent, and the surface active agent is used to reduce the surface tension of the solution and reduce the problem of foaming during use. However, for low-dielectric glass fiber cloth, adding fluorine Carbon-based surfactants or hydrocarbon-based surfactants will adsorb salt ions and affect the electronic distribution performance

Abstract

The invention belongs to the technical field of glass fiber treating agents, and particularly relates to an electronic-grade low-dielectric glass fiber cloth treating agent and a preparation method thereof. The electronic-grade low-dielectric glass fiber cloth treating agent is prepared from the following raw materials in percentage by weight of 0.6 to 1.2 percent of a coupling agent A, 0.3 to 0.8 percent of a coupling agent B, 0.01 to 1.5 percent of a coupling agent aid, 0.1 to 0.5 percent of alcohol, 0.1 to 0.5 percent of acid and the balance of water; the coupling agent A is a coupling agent containing vinyl; the coupling agent B is a coupling agent containing vinyl benzyl; and the coupling agent aid is salt of a maleic anhydride grafted modified copolymer. According to the treating agent, on the basis of meeting the low dielectric property, the bonding property of glass fiber cloth and low dielectric resin is improved, and meanwhile, the mechanical property and the heat resistance of the low dielectric glass fiber cloth are enhanced.

Description

technical field [0001] The invention belongs to the technical field of glass fiber treatment agents, and in particular relates to an electronic-grade low-dielectric glass fiber cloth treatment agent and a preparation method thereof. Background technique [0002] With the rapid development of 5G technology, the requirements for PCB board materials in the field of high-frequency and high-speed applications are also getting higher and higher, which is bound to have higher requirements for electronic-grade glass fiber cloth treatment agents as one of the important constituent materials of CCL. At present, most boards are epoxy resin systems, and the requirements for dielectric constant and dielectric loss are not so high, but for some ultra-thin cloth IC packaging substrates, high-frequency and high-speed boards, etc., the existing treatment agent formula cannot meet the requirements. The performance requirements of the low-dielectric resin system match, so it is of great signif...
