Abstract

The invention discloses an organosilicone impregnating compound for quartz glass fibers and a preparation method for the organosilicone impregnating compound and relates to the field of quartz glass fiber impregnating compounds. The impregnating compound contains the ingredients in parts by mass: 4-10 parts of silicone resin, 4-10 parts of silicone oil, 0.1-2.0 parts of antistatic agent, 0.1-2.0 parts of viscosity regulator and 78-90 parts of diluent, wherein the diluent is ethyl acetate or butyl acetate. According to the organosilicone impregnating compound for the quartz glass fibers and the preparation method for the organosilicone impregnating compound, the condition that electrical insulation properties of the quartz glass fibers are not affected can be guaranteed, meanwhile, quartz glass fiber yarn treated by using the organosilicone impregnating compound is low in hair feather volume and relatively high in fracture tensile strength.

Description

technical field [0001] The invention relates to the field of sizing agents for quartz glass fibers, in particular to an organosilicon-type sizing agent for quartz glass fibers and a preparation method thereof. Background technique [0002] Quartz glass fiber has high heat resistance, can be used below 1100°C for a long time, and can withstand high temperature up to 1700°C in an instant. At the same time, due to the excellent electrical insulation of quartz glass fiber, its dielectric constant and dielectric loss coefficient are the highest among all minerals. The best fiber, therefore, quartz glass fiber has a wide range of applications in aviation, aerospace, military industry, semiconductor, high temperature insulation, high temperature filtration. [0003] Quartz glass fiber is generally drawn from a quartz glass rod with a silica content of more than 99.95%. Due to the brittleness of quartz glass, a layer of sizing agent must be coated on the surface of quartz glass fibe...
