Problems solved by technology

For example, the Chinese patent CN201410475490.0 is an air-conditioning transformer potting glue, which only uses multiple types of epoxy resin as the basic raw material for synthesis, and does not add any modification additives such as anti-aging agents or perform corresponding surface treatment on the filler. The performance of the potting glue is largely based on the epoxy resin. Due to the natural limitations of the unmodified epoxy resin in terms of hardness, tensile strength, elongation at break, corrosion resistance, and UV aging resistance, the synthetic The performance of the potting compound is also limited

Description

technical field [0001] The invention belongs to the technical field of electrical materials, and in particular relates to an ultraviolet aging-resistant insulating glue. Background technique [0002] With the development of modern science and technology, a variety of special motors for specific purposes have emerged, which has put forward many requirements for the insulation material industry, and insulating glue is just one of them. Some electromechanical equipment, such as photovoltaic generators, must be exposed to the field for a long time and withstand the test of external environmental conditions such as high and low temperature, high radiation, and high acid-base corrosion. In order to ensure that the equipment can run stably for a long time, this requires insulating glue It has corresponding and excellent characteristics of high temperature resistance, aging resistance, acid and alkali corrosion resistance, etc., to adapt to complex environmental conditions. For exa...
