Preparation method of impregnating agent for high silicic acid glass fiber

Abstract

The invention discloses a preparation method of an impregnating agent for high silicic acid glass fiber. The impregnating agent comprises the following components in parts by weight: 0.2 to 0.6 part of coupling agent, 5 to 15 parts of reinforcing agent, 2 to 7 parts of film forming agent, 0.5 to 1.5 parts of lubricant, 0.3 to 0.5 part of antifoaming agent, 0.01 to 0.07 part of pH adjuster, 0.5 to 1.1 parts of protective agent, and 70 to 95 parts of deionized water. The preparation method comprises the following steps: adding part of deionized water into the reactor, adding a coupling agent and a pH adjuster, stirring to obtain a mixed solution (A); adding deionized water into unsaturated polyester resin in a stirring pot, adding diluted water soluble epoxy emulsion into the stirring pot, stirring, then mixing the mixture with the mixed solution (A) to obtain a mixed solution (B); adding diluted lubricant into the mixed solution (B), evenly mixing to obtain a mixed solution (C); adding an antifoaming agent and a protective agent into the mixed solution (C), stirring, and finally adding the residual deionized water.

Description

technical field [0001] The invention relates to an additive in the production process of glass fiber, in particular to a preparation method of a sizing agent for high silicic acid glass fiber. Background technique [0002] The production of high silica glass fiber is to make yarn, cloth and other products according to the production process of ordinary glass fiber with suitable original glass components. After acid leaching and thermal sintering process, the high temperature resistance performance is close to that of quartz fiber. High silica products. For the original glass components, there are mainly E glass and Si02-B203-Na2O and Si02-B203 binary systems as the original glass components. In the production process of high silica glass fiber, sizing agent is an indispensable component. At present, most of the high silica glass fiber produced by paraffin-type sizing agent commonly used in the market has burrs on the surface and many joints. , The smoothness of the surface ...
