Problems solved by technology

During the energy conversion process of the motor, the driving motor will generate a large amount of heat. If the heat cannot be transferred out in a timely and effective manner, it will cause failure of related components or even burn the driving motor, resulting in the failure of the driving system to work normally.

Abstract

The invention discloses an epoxy resin pouring sealant. The epoxy resin pouring sealant comprises modified epoxy resin and a modified anhydride curing agent according to a mass ratio of 100:(48-71); the modified epoxy resin is prepared from, by mass, 90-95 parts of epoxy resin, 5-10 parts of an epoxy diluent, 1.5 parts of a coupling agent, 0.03 part of a defoaming agent, 0.5 part of a dispersing agent and 315-355 parts of a heat-conducting filler; and the modified anhydride curing agent is prepared from, by mass, 100 parts of anhydride, 1-3 parts of a curing accelerator and 290-330 parts of afiller. The invention further provides a preparation method of the epoxy resin pouring sealant, and also provides a novel electric driven motor prepared from the epoxy resin pouring sealant. The heatresistance and heat conductivity of the epoxy resin pouring sealant are improved.

Description

technical field [0001] The invention relates to the technical field of electric drive motors. More specifically, the present invention relates to an epoxy resin potting compound, a preparation method and a novel electric drive motor. Background technique [0002] According to statistics, as of the first half of 2019, the number of cars in my country has reached 250 million, and the annual consumption of gasoline is expected to exceed 140 million tons. my country's oil resources are short, and oil imports are increasing at double-digit percentages every year. In the next 5 to 10 years, the energy gap will reach 60%, and China's dependence on foreign oil is as high as 72%. At the same time, the exhaust emissions of fuel vehicles are causing more and more serious air pollution. In large and medium-sized cities, more than 80% of carbon monoxide, more than 40% of nitrogen oxides and hydrocarbons, and 20-30% of lead-containing particles are polluted. The pollutants are all from ...
