Quartz glass fiber reinforced textile size

Abstract

The invention relates to a quartz glass fiber reinforced textile size which belongs to the technical field of glass fiber surface treatment. The size is prepared by physically mixing the following raw materials by weight percent: 1-30% of water-soluble epoxy resin, 0.1-10% of modified epoxy resin, 0.1-2.0% of cation surfactant, 0.1-2.0 nonionic surfactant, 0.1-2.0% of silane coupling agent, 0.1-10% of water-based inorganic additive, 0.1-2% of plasticizer, 0.05-0.5% of pH regulator and 20-95% of deionized water and then stirring evenly. The quartz glass fiber has favorable production process performance, favorable textile performance, high breaking strength and low hairiness amount and is capable of fully exploiting the excellent performance, so that the quartz glass fiber can be better applied to the fields of aerospace, war industry, heat insulation and the like so as to satisfy the demands of national economy and defense-related science and technology.

Description

technical field [0001] The invention relates to a quartz glass fiber reinforced textile wetting agent, which belongs to the technical field of glass fiber surface treatment. Background technique [0002] Glass fiber is brittle without surface treatment and cannot be applied. Therefore, the surface of glass fiber needs to be coated with a special surface treatment agent, that is, a sizing agent, to realize the application value of glass fiber. The quality of glass fiber is good or bad, and the number of varieties depends largely on the sizing agent, so the sizing agent is an indispensable surface treatment material in the production of glass fiber. Compared with ordinary glass fibers, quartz glass fibers have lower dielectric constant and dielectric loss, extremely low expansion coefficient, good corrosion resistance, excellent high temperature resistance and wave transparency, and are mainly used in aerospace and military fields. Since the composition of quartz glass fiber ...

AI Technical Summary

Problems solved by technology

Since the composition of quartz glass fiber is different from that of ordinary glass fiber, its application fields are also different. Therefore, the sizing agent for the surface treatment of quartz glass fiber is different from that of ordinary glass fiber. At present, the sizing agent used in domestic quartz glass fiber can be It meets certain textile process performance, but its strength is not high, about 0.45N / tex, and its high temperature resistance is average, which cannot meet the requirements of the application field of quartz fiber. Therefore, it is necessary to develop a unique silica glass fiber sizing agent. Give full play to the excellent performance of quartz glass fiber, so that it can be better used in aerospace military industry, thermal insulation, high temperature resistance and other fields, and meet the needs of private and national defense science and technology
