Abstract

The invention provides breakdown-resistant insulating paint. The breakdown-resistant insulating paint is prepared by mixing emulsion A and emulsion B in a weight ratio of the mixing emulsion A to the emulsion B of 10:1, wherein the emulsion A comprises 30 to 60 parts of organic silicon modified epoxy resin, 50 to 80 parts of filler, 20 to 50 parts of mixed solvent, 5 to 20 parts of inorganic thickening agent, 5 to 10 parts of toughening agent, 5 to 15 parts of flame retardant and 5 to 15 parts of auxiliary flame retardant; and the emulsion B comprises 10 to 30 parts of curing agent and 10 to 30 parts of mixed solvent. One or more of mica powder, ceramic powder, aluminium hydroxide and quartz sand serves as the filler, so the breakdown-resistant insulating paint has excellent breakdown resistance. The breakdown-resistant insulating paint has high adaptability, excellent weather resistance and ageing resistance, excellent adhesion to various metal base materials, high solid content, lowvolume shrinking percentage when being dried and cured and high cracking resistance; and the breakdown-resistant insulating paint can be cured at normal temperature, so the breakdown-resistant insulating paint is simple, convenient, safe and reliable for application.

Description

technical field [0001] The invention relates to an insulating coating, in particular to a breakdown-resistant insulating coating with organosilicon modified epoxy resin as the main base material. Background technique [0002] With the development of the science and technology industry, we have higher and higher requirements for the performance of insulating materials. We have developed H-class, C-class, outdoors with excellent performance, and can be used in high temperature, humidity, severe cold, large temperature difference, strong radiation, corrosive High-voltage insulating materials for harsh environmental conditions such as oil pollution, salt spray, etc. are a worldwide topic in the field of new electrical materials. Among them, the breakdown resistance of the material is an important index to measure the electrical performance of the material, and the insulation failure caused by the breakdown of the material often brings catastrophic consequences. The breakdown me...
