Embodiment 1

[0030] (1) First weigh each component according to the corresponding mass percentage in formula table 1, and set aside;

[0031] (2) Add talcum powder, mica powder, defoamer, leveling agent, wetting dispersant and pigment into the active diluent as fillers, disperse with a high-speed dispersing homogenizer for 10 minutes, and ultrasonicate for 5 minutes to disperse and Ultrasound is one cycle, and the treatment is repeated for 5 cycles to obtain a dispersion;

[0032] (3) Mix the dispersion liquid prepared in step (2) with epoxy acrylate and photoinitiator, and after stirring evenly, adopt the method of high-speed dispersion and ultrasonic treatment in step (2) alternately for 5 cycles, paint is obtained.

Embodiment 2-3

[0034] (1) Weigh the corresponding components according to the formula table 1 for later use;

[0035] All the other steps are the same as in Example 1.

Abstract

The invention provides a heat-resistant insulating paint with fast curing speed. The heat-resistant insulating paint comprises the following ingredients in parts by weight: 30-40 parts of epoxy acrylate, 30-50 parts of activated diluent, 1-10 parts of photoinitiator, 5-15 parts of talcum powder, 1-10 parts of mica powder, 0.1-0.3 parts of defoaming agent, 0.1-0.5 parts of levelling agent, 0.01-2 parts of wetting dispersing agent, and the balance of pigment, wherein the mass ratio of epoxy resin to acrylic acid in the epoxy acrylate is 2:1, and the activated diluent is triuret propylene glycol diacrylate. The heat-resistant insulating paint with fast curing speed has the advantages of being fast to cure, and good in impact resistance and flexibility and other mechanical properties, the paint is good in insulation and heat resistance, as well as green and environmentally-friendly, thus being a heat-resistant insulating paint which is wide in application range and suitable for use in large-scale production.

Description

technical field [0001] The invention relates to an insulating coating, in particular to a heat-resistant insulating coating with fast curing speed. Background technique [0002] In order to ensure the normal operation of power equipment under various special conditions, it is necessary to develop insulating materials suitable for various working environments to improve the ability of power equipment to adapt to the environment and prolong the service life of the equipment itself. At present, there are many types of insulating materials, such as insulating packaging materials, insulating paper, insulating plastics, insulating coatings, etc. Among them, insulating coatings are more and more used in various industries due to their simple preparation method and convenient construction process. on the device. [0003] At present, there are many kinds of insulating coatings that can be adapted to high-temperature environments. These coatings can still maintain good mechanical pro...
