Abstract

The invention belongs to the technical field of secondary slurry of warps of electronic glass fiber cloth and particularly relates to a method for preparing secondary slurry of environmental-friendlyenergy-saving electronic glass fiber cloth. The method comprises the following steps: putting softening water into a blending tank, and starting stirring at a normal temperate; stirring with SH-200 for 5-10 minutes; further adding an anti-electrostatic agent, and stirring for 7-13 minutes; testing the mass concentration of the obtained secondary slurry as 1.2-2.6%, and putting into a slurry storage tank for later use. The secondary slurry of the environmental-friendly energy-saving electronic glass fiber cloth, which is prepared by using the method, is small in ash content, low in required desizing temperature, short in desizing time, small in glass fiber cloth tension strength loss, good in energy conservation, low in consumption, low in cost, meanwhile easy to degrade and generally freeof pungent smell after being combusted.

Description

technical field [0001] The invention belongs to the technical field of warp secondary size applied to electronic glass fiber cloth, and in particular relates to a method for preparing the secondary size of environmental protection and energy-saving electronic grade glass fiber cloth. Background technique [0002] Electronic glass fiber cloth is woven from electronic grade glass fiber yarn. The manufacturing process of electronic-grade glass fiber yarn used for weaving is to mix and dissolve silica sand, boronite, etc. in a furnace to form a co-melt, and then spin through a platinum bushing at high speed. In the spinning process, the previous size is required to prevent the yarn from breaking and hairiness during the spinning process. The primary slurry in the spinning process is called "primary slurry". [0003] The specific steps of the glass fiber cloth manufacturing process are: 1. Sizing: first arrange the warp yarns according to a certain number, and then perform seco...
