Abstract

The invention relates to an epoxy resin compound aqueous emulsion and discloses an epoxy resin compound aqueous emulsion which can be used for manufacturing glass fiber film-forming agent for wind turbine blades. The glass fiber prepared by the aqueous emulsion, being used as the film-forming agent, is particularly suitable for the preparation of the wind turbine blades, and the aqueous emulsion does not contain VOC (volatile organic compounds) and nonyl phenols surface active agents, thus the aqueous emulsion has good safety and environment-friendly performances. The epoxy resin compound aqueous emulsion is characterized in that the aqueous emulsion can be used as the film-forming agent to draw glass fiber for manufacturing the wind turbine blades, all the indications including the penetration velocity, the composite material performance and the like; the aqueous emulsion is well in storage stability and use stability and is safe and environment-friendly. The aqueous emulsion mainly comprises epoxy resin, an emulsifying agent and deionized water. The epoxy resin aqueous emulsion provided by the invention can be used for large-scale wiredrawing work by a tank furnace method, thus the process is stable and the manufacturing cost is low.

Description

technical field [0001] The present invention is a special film-forming agent for yarn glass fibers for wind power blades, and a method for preparing an epoxy resin water emulsion. The epoxy resin water emulsion emulsified by a traditional method is used as a film-forming agent for glass fibers for wind power blades. , its penetration speed and strength are not up to the requirements, the water emulsion does not contain VOC, does not contain nonylphenol surfactants, and meets environmental protection requirements. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge, and the total amount of wind energy resources in the world is about 100%. Its reserves are huge. The total global wind energy resources are about 2.74×109 MW, of which the available wind energy is 2×107 MW. With the development of the world economy, the wind energy market has also developed rapidly...
