Abstract

The invention discloses a sizing agent formula of a glass fiber cloth. The sizing agent formula is prepared from the following raw materials A and the following raw materials B, wherein the raw materials A include the following components in parts by weight: 3 parts of polyformaldehyde, 2 parts of graphite, 2 parts of a defoamer, 18 parts of main sizing agent starch, 2 parts of a binder and 3 parts of a surface activator; and the raw materials B include the following components in parts by weight: 4 parts of first PVA, 6 parts of second PVA, 3 parts of PEG and 57 parts of deionized water. Thepreparation method of the sizing agent formula of the glass fiber cloth comprises the following specific steps that the deionized water is added to stir and dissolve the raw material A, and the watertemperature is controlled at 20-30 DEG C; the first PVA in the raw material B is added for dissolving through a funnel container, the speed is controlled by a funnel, and stirring is conducted after adding; the second PVA and the PEG are sequentially added through the same method in the step (2); steam is blown in the stirring process, the temperature of the liquid is increased to 85-95 DEG C, then heat preservation is conducted for 60 minutes, and heating is stopped; and natural cooling is conducted to reach the room temperature state for standby application. The abrasion resistance of the fiber cloth sizing agent can be improved, the filament breakage rate and the defective rate in production are decreased, and processing of the fiber cloth is facilitated.

Description

technical field [0001] The invention relates to the technical field of electronic fiber cloth processing, in particular to a formula of ultra-thin electronic grade glass fiber cloth with high wear resistance slurry and a method thereof. Background technique [0002] Electronic grade glass fiber cloth is the basic material of printed circuit boards and is widely used in various electronic fields. With the development of electronic products in the direction of lightness, thinness and shortness, the basic material copper clad substrate used in electronic products is also required to develop in the direction of high density, lightness, multi-layer and lead-free and halogen-free. The appearance and physical properties of glass fiber cloth put forward higher requirements: high dimensional stability, impregnation, and no colloidal particles on the surface. Since the warp and weft monofilament diameter of ultra-thin cloth is 5 microns or even smaller, it is difficult to control the...
