Problems solved by technology

Due to the wide application of electricity in social production and human life and the rapid development of electronics and communication technology, the power distribution cabinet, as an integral part of the substation, is exposed to harsh outdoor weather all year round and is susceptible to aging and reduced service life due to ultraviolet radiation.
[0003] On the other hand, the installation methods of the distribution box are divided into two types: surface installation and concealed installation. The heat dissipation effect of the exposed distribution box is better than that of the concealed installation. Poor, causing the temperature of the surrounding air in the distribution box to rise due to the temperature rise of the low-voltage circuit breaker

Abstract

The invention discloses an insulating coating material for a power distribution cabinet. The insulating coating material is prepared from the following raw materials in parts by weight: 75-85 parts of a modified waterborne polyurethane emulsion, 8-10 parts of waterborne alkyd resin, 4-8 parts of diethylenetriamine, 10-14 parts of cyclohexanone, 12-15 parts of ethyl acetate, 2-3 parts of an aluminate coupling agent, 15-25 parts of a thermal conducting filler, 10-12 parts of a processing aid, 14-18 parts of an ore adding powder and 7-9 parts of anticracking fiber. The insulating coating material has excellent insulating property, film-forming property and mechanical property, good high temperature resistance, excellent antiseptic and moisture-proof properties, good anti-ultraviolet property and ageing resistance, relatively high adhesive force and relatively good heat-conducting property; and meanwhile, according to the preparation method of the insulating coating material, the material cost is relatively low, the raw materials are available and the process is simple, so that the insulating coating material has relatively high practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of electric power distribution cabinets, in particular to an insulating coating material for electric power distribution cabinets and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of my country's national economy, the demand for electricity has shown a rapid growth trend. In order to meet the needs of industrial and agricultural products and people's daily life, substations with a voltage level of 110kV and above are gradually built in the central area of ​​the city. Due to the wide application of electricity in social production and human life and the rapid development of electronics and communication technology, the power distribution cabinet, as an integral part of the substation, is exposed to harsh outdoor weather all the year round, and is susceptible to aging and reduced service life caused by ultraviolet radiation. [0003] On the other h...
