Ultra-thin electronic glass fiber cloth surface treatment fluid and preparation method thereof

Abstract

The invention provides ultra-thin electronic glass fiber cloth surface treatment fluid and a preparation method thereof, and belongs to the technical field of electronic grade glass fiber surface treatment. The ultra-thin electronic glass fiber cloth surface treatment fluid comprises the following raw materials in parts by weight: 98 parts of water, 1.1 to 1.5 parts of surface treating agent, 0.1to 1 part of weak acid, and 0.002 to 0.01 part of antifoaming agent; the surface treating agent comprises Y-aminopropyltrimethoxysilane and N-(2-aminoethyl)-3-aminopropyltrimethoxysilane; and the Y-aminopropyltrimethoxysilane and the N-(2-aminoethyl)-3-aminopropyltrimethoxysilane are mixed according to a weight ratio of 1.1 to 1.3:1. The ultra-thin electronic glass fiber cloth surface treatment fluid provided by the invention increases the bonding force between resins and glass fiber cloths, improves the heat resistance and ion migration resistance of electronic glass fiber cloths, and makes the electronic glass fiber cloths more suitable for manufacturing high-end printed circuit copper clad laminates.

Description

technical field [0001] An ultra-thin electronic glass fiber cloth surface treatment liquid and a preparation method thereof belong to the technical field of electronic grade glass fiber surface treatment. Background technique [0002] Electronic glass fiber cloth woven from electronic grade glass fiber, referred to as electronic glass fiber cloth, is an essential basic material for copper clad laminate and printed circuit board industry, and its performance determines the quality of copper clad laminate and printed circuit board to a large extent. Electrical properties, mechanical properties, dimensional stability and other important properties. [0003] The warp and weft yarns used in the electronic glass fiber cloth for copper clad laminates, each yarn is made of a single fiber with a diameter of 5-9um and a number of 400-800 single filaments. During the drawing process, the surface is coated with a layer of sizing agent to ensure that each The adhesion of the ply yarn al...

AI Technical Summary

Problems solved by technology

[0005] The applicant found through research that the existing surface treatment liquid has the following problems: First, the electronic glass fiber cloth treated with the existing surface treatment liquid has poor heat resistance, and the electronic glass fiber cloth is prone to bubble stratification after long-term high-temperature cooking Problem; secondly, the electronic glass fiber cloth treated with the existing surface treatment liquid and the ion migration resistance are not good, which has a negative impact on the performance of the copper clad laminate
