Abstract

The invention discloses an insulation coating for the surface of a low-voltage electric appliance and a preparation method thereof, and relates to the technical field of the insulation coating. The insulation coating is prepared from the following raw materials in parts by weight: 20-30 parts of rubber powder, 15-25 parts of epoxy resin, 10-15 parts of organic silicon resin, 6-15 parts of nanosilicon dioxide, 3-8 parts of nano-zinc oxide, 3-8 parts of nano-magnesium oxide, 3-8 parts of nano-aluminium oxide, 8-16 parts of glass fiber, 6-15 parts of attapulgite, 3-8 parts of calcium stearate, 1.2-2.5 parts of dispersant, 0.8-1.5 parts of defoamer, 2-5 parts of anti-aging agent, 1.5-3.2 parts of adhesive force accelerant and 3.6-6.2 parts of curing agent. The insulation coating has the advantages of high insulation performance, high binding force, easiness in even coating, good anti-aging performance, small possibility of oxidative cracking, long service life, high practicality, simple and easily-learnt preparation process, high operability and easiness in mass production and popularization.

Description

technical field [0001] The invention relates to the technical field of insulating coatings, in particular to an insulating coating for the surface of low-voltage electrical appliances and a preparation method thereof. Background technique [0002] A low-voltage electrical appliance is a component or device that can switch, control, protect, detect, transform and adjust circuits or non-electrical objects by manually or automatically switching on and off circuits according to external signals and requirements. Low-voltage electrical appliances can be divided into two categories: power distribution appliances and control appliances, which are the basic components of complete sets of electrical equipment. In industry, agriculture, transportation, national defense and people's power consumption departments, most of them use low-voltage power supply, so the quality of electrical components will directly affect the reliability of low-voltage power supply system. [0003] In order ...
