Abstract

The invention discloses a novel glass fiber soaking agent. The soaking agent is composed of the following raw materials by weight: 30-40 parts of polypropylene wax emulsion, 15-20 parts of modified starch, 8-13 parts of polyvinyl acetate, 2-6 parts of silane coupling agent, 1-4 parts of sodium dodecylbenzenesulfonate, 1-3 parts of fluorocarbon surfactant, 5-8 parts of perilla seed oil, 3-6 parts of modified nano zinc oxide, 2-5 parts of graphene, 1-2 parts of lubricant, 0.5-1 part of pH adjuster, 2-4 parts of nano titanium dioxide, 0.5-1 part of antifoaming agent and 70-85 parts of water. Thecomponents of the soaking agent have a reasonable ratio, the modified starch effectively ensures the film-forming lubricity of the soaking agent as a whole, and the mechanical properties of soaked glass fiber yarns are greatly improved, and the perilla seed oil and the silane coupling agent improve lubrication, plasticization and antibacterial effects of the soaking agent.

Description

technical field [0001] The invention relates to the technical field of glass surface coating, in particular to a novel glass fiber sizing agent. Background technique [0002] Electronic-grade glass fiber cloth has the advantages of uniform weight and low dielectric constant. It has become the most widely used copper-clad laminate reinforcement substrate. According to the data released by the IPC Association, glass fiber cloth-based copper-clad laminates account for 50% of the entire market share. %above. [0003] Electronic grade glass fiber cloth is processed by electronic grade spun yarn after weaving and post-processing. Post-treatment is the production process of removing the protective layer on the surface of glass fiber cloth and coating with chemical components that can be combined with matrix resin. After post-processing, it can Endow electronic grade glass fiber cloth with various post-processing properties. [0004] The final product of electronic-grade glass fib...
