Embodiment 1

[0046] Example 1, bake the epoxy resin to a flow state, put it into the emulsification tank, 2000g, then put in 200g emulsifier A, 40g emulsifier B in turn, adjust the temperature in the emulsification tank to 70°C, and select the stirring speed to 1200r / min , began to add water slowly until it turned into an aqueous phase, and then slowly added water to dilute to a solid content of 55%. Analyze the properties of the samples. And conduct drawing test.

Embodiment 2

[0047] Example 2, add the epoxy resin to the flow state, put it into the emulsification tank, 2000g, then put in 180g of emulsifier A, 36g of emulsifier B in turn, adjust the temperature in the emulsification tank to 70°C, and select the stirring speed to be 1200r / min , began to add water slowly until it turned into an aqueous phase, and then slowly added water to dilute to a solid content of 55%. Analyze the properties of the samples. And conduct drawing test.

Abstract

The invention relates to an epoxy resin complex aqueous emulsion. The epoxy resin complex aqueous emulsion is used for preparing a film forming agent used for glass fibers for wind turbine blades. The glass fibers prepared through using the aqueous emulsion as a film forming agent are especially suitable for making wind turbine blades. The aqueous emulsion contains no VOC, contains no nonyl phenol surfactants, and has good safety and environmental protection properties. The wind turbine blades made of the glass fibers drawn through using the aqueous emulsion as the film forming agent have excellent soaking speed, composite material performances and other indexes; and the water emulsion has the advantages of good storage stability and use stability, safe use, and environmental protection. The aqueous emulsion mainly includes epoxy resin, an emulsifier and deionized water. The epoxy resin aqueous emulsion can be used in tank furnace wire drawing working in a large scale manner, the process is stable, and the production 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 epoxy resin water emulsion. The epoxy resin water emulsion emulsified by the 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....
