Abstract

The invention discloses epoxy glue for protecting the end part of a stator of a wind power motor. The epoxy glue comprises double components, i.e., a main agent A and a curing agent B, wherein the main agent A is prepared mainly from bisphenol A epoxy resin, toughened resin, low-shrinkage epoxy resin, a reactive diluent, a silane coupling agent, an organic silicon defoaming agent, fumed silica and an inorganic filler; the curing agent B is prepared mainly from a flexible curing agent, an active curing agent and an accelerant; the toughened resin is epoxy / organic silicon hybrid core-shell rubber structure resin or epoxy / organic silicon hybrid block copolymerization resin. The invention further discloses a preparation method of the epoxy glue, which comprises preparation methods of the main agent A and the curing agent B. The epoxy glue disclosed by the invention has excellent low-temperature resistance and heat resistance, has very good flexibility and toughness, and can effectively prevent a cracking failure of the product in the process of carrying out encapsulation protection on the stator of the wind power motor, which is caused by the temperature drastic change.

Description

technical field [0001] The invention belongs to the technical field of epoxy glue, and in particular relates to an epoxy glue for protecting the stator end of a wind power motor and a preparation method thereof. Background technique [0002] With the continuous increase of people's demand for energy, the ways of obtaining new energy are also becoming more and more diversified. Among them, the sudden emergence of wind power technology has provided human beings with a new channel to obtain clean and renewable energy. Wind turbines have the characteristics of huge size and diverse operating environments. The polymer insulating materials used in them are also required to have excellent environmental adaptability, and can withstand long-term low temperature, high temperature, rain erosion, salt spray, and high and low temperature changes. Etc., especially the erosion of rainwater is particularly prominent. [0003] At present, at home and abroad, the sealing and insulation treat...
