Problems solved by technology

[0007] Another object of the present invention is to provide a silicone potting compound and a method for preparing an organic potting compound. Composition, by baking and preheating component A and component B at a certain temperature and mixing them in a certain proportion, a silicone potting compound for electric drive motors with low mixed viscosity is obtained, and a new type of electric drive motor is also provided. The potting glue is poured into the gap between the electric drive motor stator, rotor and other parts and the casting mold, and heated and cured at a certain temperature and time to obtain an electric drive motor with excellent comprehensive performance. The electric drive motor is cured with silicone potting glue The material has good heat resistance and high thermal conductivity, which solves the problem that the temperature rises too fast and too high when the electric drive motor is running, improves the reliability of the electric drive motor and prolongs its service life

Abstract

The invention discloses an organic silicon pouring sealant. The organic silicon pouring sealant is formed by adding two components and is obtained by mixing a component A and a component B according to the mass ratio of 1: 1, and the component A is prepared from the following components in parts by mass: 100 parts of vinyl polysiloxane, 470-530 parts of heat-conducting filler, 1.5 parts of a coupling agent, 0.5 part of a dispersing agent and 0.2-1.5 parts of catalyst; and the component B is prepared from the following components in parts by weight: 100 parts of vinyl polysiloxane, 2-23 parts of hydrogen-containing polysiloxane, 430-480 parts of filler and 0.1-1 part of an inhibitor. The organic silicon pouring sealant provided by the invention has the beneficial effects of good heat resistance and high heat conductivity coefficient, solves the problem that the temperature rises too fast and too high when an electric drive motor runs, and improves the reliability of the electric drive motor.

Description

technical field [0001] The invention relates to the technical field of potting glue. More specifically, the present invention relates to a silicone potting compound, a preparation method and a new electric drive motor. Background technique [0002] According to statistics from the National Bureau of Statistics, by the end of 2019, the number of cars in my country has exceeded 260 million, and the annual gasoline consumption is nearly 130 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 ...
