Preparation process of insulating resin for completely sealed bus duct

Abstract

The invention discloses a preparation process of insulating resin for a completely sealed bus duct. The process comprises the following steps: (1) putting 5-15 parts of acrylic resin into a container, adding 10-20 parts of a mixed solvent, and stirring and dispersing for 30-40 minutes at the rotation speed of 4000-6000r / minute, thereby obtaining primary emulsion; (2) adding 2-8 parts of zinc chromate, 1-5 parts of zinc chloride, 2-6 parts of mica powder and 1-5 parts of pigment into the primary emulsion, and stirring and dispersing for 20-30 minutes at the rotation speed of 3600-4200r / minute, thereby obtaining a sizing agent; (3) mixing epoxy powder with benzophenone tricarboxylic acid anhydride, further adding 10-20 parts of the mixed solvent to mix with first inorganic packing, second inorganic packing, third inorganic packing and the sizing agent, and stirring and dispersing for 10-20 minutes at the rotation speed of 0-1200r / minute; and (4) adding 5-10 parts of organosilicone polyether polyol, 1-5 parts of ethylidene bioctadecanamide, 5-10 parts of crylic acid resin and 10-15 parts of polyamide resin into the mixed liquid, and stirring and dispersing for 10-20 minutes at the rotation speed of 600-1100r / minute, thereby obtaining the insulating resin for the completely sealed bus duct.

Description

technical field [0001] The invention relates to the field of manufacturing and processing of fully enclosed bus ducts, in particular to a preparation process of insulating resin for fully enclosed bus ducts. Background technique [0002] Insulating paint is a paint with excellent electrical insulation properties, which can be used as a protective coating for products or components in the electrical and electronic industry. With the development of the science and technology industry, we have higher and higher requirements for the performance of insulating coatings. 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 coatings for harsh environmental conditions such as oil, oil, and salt spray are a worldwide topic in the field of new electrical materials.

Problems solved by technology

[0003] When insulating coatings are applied to equipment related to power systems, their performance is not only insulation, but also high temperature resistance, corrosion resistance, and impact resistance. At present, traditional insulating coatings have some defects, such as insufficient coating adhesion. , Easy to layer, fall off, low solid content, thin film formation, serious environmental pollution, short insulation life, etc.
