Embodiment 1

[0026] This example is an aqueous epoxy resin emulsion for glass fibers.

[0027] Said aqueous epoxy resin emulsion for glass fiber consists of 43.01% epoxy resin, 5.16% polybutadiene peroxide, 1.29% ethylene oxide, 3.23% diacetone alcohol and 47.31% deionized water composition. The stated percentages are mass percentages.

[0028] The epoxy resin is bisphenol A liquid epoxy resin.

[0029] The preparation process of this embodiment is:

[0030] Step 1, add epoxy resin accounting for 43.01% of the total system into a beaker, add a weighed organic solvent diacetone alcohol, turn on the high-speed shear emulsification mixer, and continue stirring for 10 minutes, so that diacetone alcohol and epoxy resin are fully mixed , The viscosity of the epoxy resin is significantly reduced, and the stirring speed is 3000r / min. Obtain epoxy resin mixture.

[0031] Step 2, add weighed polybutadiene peroxide and ethylene oxide into the obtained epoxy resin mixture, and keep the stirring s...

Embodiment 2

[0036] This example is an aqueous epoxy resin emulsion for glass fibers.

[0037]The described aqueous epoxy resin emulsion for glass fiber consists of 35% epoxy resin, 3% polybutadiene peroxide, 4% ethylene oxide, 2% diacetone alcohol and 57% deionized water composition. The stated percentages are mass percentages.

[0038] The epoxy resin is bisphenol A liquid epoxy resin.

[0039] The preparation process of this embodiment is:

[0040] Step 1, add the epoxy resin accounting for 35% of the total system into the beaker, add the weighed organic solvent diacetone alcohol, start the high-speed shear emulsification mixer, and continue stirring for 10 minutes, so that the diacetone alcohol and the epoxy resin are fully mixed, The viscosity of the epoxy resin is obviously reduced, and the stirring speed is 3000r / min. Obtain epoxy resin mixture.

[0041] Step 2: Add weighed polybutadiene peroxide and ethylene oxide into the obtained epoxy resin mixture, and keep stirring for 10...

Embodiment 3

[0046] This example is an aqueous epoxy resin emulsion for glass fibers.

[0047] Said aqueous epoxy resin emulsion for glass fibers consists of 41.7% epoxy resin, 4.3% polybutadiene peroxide, 3.16% ethylene oxide, 5.11% diacetone alcohol and 45.73% deionized water composition. The stated percentages are mass percentages.

[0048] The epoxy resin is bisphenol A liquid epoxy resin.

[0049] The preparation process of this embodiment is:

[0050] Step 1, add the epoxy resin accounting for 41.7% of the total system into the beaker, add the weighed organic solvent diacetone alcohol, turn on the high-speed shear emulsification mixer, and continue stirring for 10 minutes, so that the diacetone alcohol and the epoxy resin are fully mixed , The viscosity of the epoxy resin is significantly reduced, and the stirring speed is 3000r / min. Obtain epoxy resin mixture.

[0051] Step 2, add weighed polybutadiene peroxide and ethylene oxide into the obtained epoxy resin mixture, and keep ...

Abstract

The invention discloses a waterborne epoxy resin emulsion for glass fibers and a preparation method of the waterborne epoxy resin emulsion. By using diol compounds of oxiron and ethylnen oxide emulsifier and shearing and stirring at high rotating speed of 8000r / min and simultaneously combining a phase inversion technique, the prepared epoxy resin emulsion finishes the process from a water-in-oil flow to an oil-in-water flow; the particle size range of the prepared emulsion is 150 to 300nm; the waterborne epoxy resin emulsion has the characteristics of narrow particle size range, concentrated particle size distribution and stable centrifugal performance; after the waterborne epoxy resin emulsion is stood at normal temperature and normal pressure for 12 months, no demulsification or layering phenomenon is cuased; after the emulsion is dried at the temperature of 110DEG C, a formed membrane is hard, good in toughness and high in strength.

Description

technical field [0001] The invention relates to a preparation method of water-based epoxy resin, relates to a preparation method of epoxy resin emulsion, and belongs to the technical field of glass fiber production. Background technique [0002] Glass fiber is an engineering material with excellent properties such as non-combustibility, corrosion resistance, high temperature resistance, low moisture absorption, and low elongation. It is widely used in construction, electronics, aviation, national defense and other fields. , High brittleness and other characteristics, can not be used directly, it is necessary to coat a mixture in the production of glass fiber, so that it can play the role of lubrication, bonding, clustering, etc. The glass fiber of the mixture not only has superior folding resistance, but also can meet the needs of further processing of the glass fiber. At the same time, it can make the glass fiber have good compatibility with the substrate and interfacial ch...
