Abstract

The invention discloses waterborne fluorocarbon insulation paint modified by aramid fibers, which includes a component A and a component B, wherein the component A is mainly prepared from waterborne fluorocarbon resin, aramid fibers, a pigment, filler, an additive and water, and the component B mainly is a waterborne isocyanate curing agent. The method includes: 1) dispersing the aramid fibers inwater to obtain waterborne slurry containing short-cut aramid fibers; 2) mixing and uniformly dispersing the pigment, filler and a part of additive to obtain waterborne slurry containing the pigment and filler; 3) mixing the slurry in the step 1) and 2) and adding the waterborne fluorocarbon resin and other additive, and uniformly dispersing the components to prepare the component A; 4) accordingto the ratio, preparing the waterborne isocyanate curing agent as the component B. The fluorocarbon insulation paint has excellent anti-chemical corrosion and anti-salt fog performances, has excellentweather resistance and heat resistance, and is great in flame-retarding performance and electrical insulation property.

Description

technical field [0001] The invention belongs to the field of water-based insulating varnish, in particular to an aramid fiber modified water-based fluorocarbon insulating varnish and a preparation method thereof. Background technique [0002] At present, the traditional surface insulating varnish is generally oily epoxy resin, silicone resin, fluorocarbon resin, alkyd resin, etc. This type of insulating varnish has good electrical properties and is widely used in various fields of electrical insulation. However, the traditional oil-based surface insulating enamel contains a large amount of organic solvents. During the film-forming and curing process of the coating, the organic solvents all evaporate into the atmosphere, which not only causes pollution and harm to the environment and human health, but also causes a huge waste of resources. Water-based insulating varnish is relatively safe and environmentally friendly compared to oil-based insulating varnish. [0003] Chinese...
