D450 electronic yarn impregnating agent and preparation method thereof

Abstract

The invention relates to a D450 electronic yarn impregnating agent and a preparation method thereof. The D450 electronic yarn impregnating agent is prepared from, by mass, 1.0%-10.0% of starch-type film-forming agent, 0.25%-1.5% of auxiliary film-forming agent, 0.5%-1.5% of lubricant, 0.2%-1.0% emulsifier, 0.5%-2.5% of plasticizer, 0.001%-0.01% of defoamer, 0.003%-0.03% of preservative and the balance water. In the D450 electronic yarn manufacturing technology process, the D450 electronic yarn impregnating agent is coated to glass fiber to form an impregnating agent film, abrasion of glass fiber tows can be effectively reduced, hairiness is effectively reduced, meanwhile the D450 electronic yarn impregnating agent also has higher mechanical strength, and the surface properties of electronic base cloth are ensured.

Description

technical field [0001] The invention belongs to the field of glass fiber yarns, and in particular relates to a D450 electronic yarn sizing agent and a preparation method thereof. Background technique [0002] Glass fiber electronic yarn is the main substrate or frame material for the production of printed terminal products - printed circuit boards (PCB). In recent years, with the development of the electronics industry, the demand for various electronic-grade glass fiber fabrics in the market has grown rapidly. With the development of PCB substrates in the direction of thinning, multi-layering, and high-density, the demand for electronic base fabrics made of electronic yarns is gradually increasing. [0003] At present, the electronic yarn usually adopts the multi-split drawing process of the porous large drain plate in the pool kiln, through forced cooling, roller type monofilament oiling and impregnation, etc., with the control of air flow and temperature and humidity, an...

Problems solved by technology

At the same time, during the twisting and weaving process of the current D450 electronic yarn, the sizing agent coated on the surface of the glass fiber yarn is easy to fall off, which leads to an increase in the hairiness of the fabric surface in the subsequent weaving process, which seriously affects the surface properties of the electronic base fabric.
