Problems solved by technology

Due to the complexity of the composition and usage of the existing emulsifiers, the cost of emulsifying epoxy resin is very high, resulting in an increase in production costs
At the same time, due to the unreasonable composition of the emulsifier and the unreasonable production method, the cost of the emulsifier has also increased, thereby indirectly increasing the cost of the emulsification operation.

Abstract

The invention relates to a waterborne epoxy resin emulsifier, which comprises: polyethylene glycol 6000, polysorbate-80, trimethylolpropane glycidyl ether, 828 epoxy resin and a boron trifluoride etherate complex. The invention has the beneficial effects that: the production is energy-saving and efficient, use of the emulsifier is stable and environment-friendly, traditional process equipment canachieve production, and refitting investment of equipment is unnecessary.

Description

technical field [0001] The invention relates to the production field of emulsifying additives, in particular to a water-based epoxy resin emulsifier and its preparation method and use method. Background technique [0002] Water-based epoxy emulsifiers are mainly used for emulsifying epoxy resins. They are mainly composed of epoxy-terminated polyetherketone double-word surfactants, which can quickly emulsify epoxy resins at medium or high temperatures. Due to the complicated composition and usage methods of the existing emulsifiers, the emulsification operation cost of epoxy resin is very high, resulting in the increase of production cost. At the same time, due to the composition of the emulsifier and the unreasonable production method, the cost of the emulsifier is also increased, thereby indirectly increasing the cost of the emulsification operation. Contents of the invention [0003] The purpose of the present invention is in order to solve the problems referred to abov...
