Problems solved by technology

However, because most of the existing fiber opening methods are carried out after the glass fiber cloth is impregnated with the silane coupling agent, the existing fiber opening method not only has limited fiber opening effect, but also easily destroys the silane coupling agent coated on the glass. The integrity of the fiber cloth, which in turn affects the properties of the glass fiber cloth

Embodiment 1

[0032] Example 1: A glass fiber cloth (such as 2116 cloth) is subjected to the processing method of the glass fiber cloth made of low-dielectric glass fiber filaments, and the product is obtained by heating and drying. In the treatment liquid, the silane coupling agent is methacryloxypropyl trimethoxysilane (manufactured by Dow Corning Co., Ltd.; OFS6030), and the surfactant is polyethanol phenol ether, partial fluorine Alcohol replaces ethylene glycol and polyoxypropylene polyoxyethylene ether.

Embodiment 2

[0033] Embodiment 2: A glass fiber cloth (such as 1080 kinds of cloth) implements the processing method of the glass fiber cloth made of low-dielectric glass fiber yarn, and heats and dries, and then utilizes high-pressure water to carry out fiber opening treatment to obtain products. In the treatment liquid, the silane coupling agent is methacryloxypropyl trimethoxysilane (manufactured by Dow Corning Co., Ltd.; OFS6030), and the surfactant is polyethanol phenol ether, partial fluorine Alcohol replaces ethylene glycol and polyoxypropylene polyoxyethylene ether.

Embodiment 3

[0034] Embodiment 3: Implement the processing method of glass fiber cloth made of low-dielectric glass fiber filaments on a glass fiber cloth (such as 1078 cloth), and perform heating and drying treatment to obtain a product. In the treatment liquid, the silane coupling agent is methacryloxypropyl trimethoxysilane (manufactured by Dow Corning Co., Ltd.; OFS6030), and the surfactant is polyethanol phenol ether, partial fluorine Alcohol replaces ethylene glycol and polyoxypropylene polyoxyethylene ether.

Abstract

The invention discloses glass fiber cloth and a processing method of the glass fiber cloth made of low-dielectric glass fiber filaments. The glass fiber cloth is formed by weaving a plurality of glass fiber filaments. And each of the glass fiber filaments contains B2O3, SiO2, Al2O3, and MgO. Based on 100 wt% of the total weight of the glass fiber filaments, the content of B2O3 ranges from 20.13 wt% to 25 wt%, the content of SiO2 ranges from 50 wt% to 55 wt%, the content of Al2O3 ranges from 14 wt% to 19 wt%, and the content of MgO ranges from 0.1 wt% to 8.5 wt%. Therefore, the glass fiber cloth has a low dielectric constant and a low loss factor so as to meet the application requirements of high frequency and high speed.

Description

technical field [0001] The invention relates to a glass fiber cloth and a processing method of the glass fiber cloth made of glass fiber filaments, in particular to a low-dielectric glass fiber cloth and a processing method of the glass fiber cloth made of low-dielectric glass fiber filaments method. Background technique [0002] With the development of faster and low-latency wireless communication technology, the demand for high-frequency and high-speed printed circuit boards has increased, and the demand for the development of electronic materials has also been accelerated. Coupled with the development of end products towards thinner, shorter, and more precise products, they need to have lower dielectric constant (Dk) and dissipation factor (Df) to meet the demand. The existing glass fiber cloth used as a reinforcing material in the carrier board has the advantages of good insulation performance and good thermal expansion. However, the glass fiber cloth commonly used in c...
