Abstract
The present invention relates to electric arc resistance insulation enamel paint which comprises a component A using epoxy modified resin, modified resin containing an olefinic link compound, pigments and a chemical assistant as skeletal materials and a component B using a cross-linking agent, normal butyl alcohol, butyl acetate and ester with high boiling point as a diluent, wherein the component A comprises 27 to 32% of epoxy modified resin, 23 to 27% of modified resin containing an olefinic link compound, 31 to 37% of pigments, and 9 to 14% of chemical assistant; the component B comprises 15 to 18% of cross-linking agent, 20 to 25% of normal butyl alcohol, 25 to 30% of butyl acetate and 32 to 35% of ester with high boiling point. The enamel paint achieves or exceeds the foreign similar products in aspects of electric arc resistance and other electrical insulation performance.
Description
The present invention relates to a kind of electric arc electric insulating enamel, belong to the coating of anti-electric arc class.
Since quite a long period, major insulation material-THVG insullac of anti-electric arc that the invertor low-inductance bus insulation system of anti-electric arc is used in China's electric locomotive exploitation mainly adopts external import.Though this insulating enamel paint resisting electric arc has favorable applicability aspect arc resistance energy, the electrical insulation properties, price is high, has both consumed a large amount of foreign exchanges, is unfavorable for again promoting the use of.
Purpose of the present invention: be intended to seek the new formula materials of a kind of cheap and good-quality insulating enamel paint resisting electric arc, not only wish its material of basing on our country, save foreign exchange, eliminate its dependence, but also wish that it can reach the same physicochemical property of materials overseas materials overseas, technology.
This insulating enamel paint resisting electric arc by epoxy modified resin, contain the compound modified resin of ethylene linkage, pigment and chemical assistant the A component and form with the B component of linking agent, propyl carbinol, butylacetate and high boiling ester, the proportioning that it is characterized in that A component and B component is 1: 2～2.8.
The incorporation of described each constituent of A component is respectively an epoxy modified resin 27～32%: contain the compound modified resin 23～27% of ethylene linkage; Pigment 31～37%; Chemical assistant 9～14%.
The incorporation of described each constituent of B component is respectively: linking agent 15～18%; Propyl carbinol 20～25%; Butylacetate 25～30%; High boiling ester 32～35%.
Described linking agent is to be mixed by lauroleate and silicic acid fat; Or the mixture of naphthenate etc.
According to this insulating enamel paint resisting electric arc of above formulated, at surface drying time, anti-arc duration, hardness of paint film, the hydrophobicity performance aspects is suitable with external like product, but significantly is lower than external like product on the cost of product.
Below in conjunction with embodiments of the invention, and further set forth the present invention in conjunction with the embodiments.

Butylacetate 25%
High boiling ester 32%
A component: B component=1: 2.8
The actual fabrication processing step of this insulating enamel paint resisting electric arc is as follows:
At first A component and B component are prepared by the embodiment ratio requirement, its A component join method by three programs, the first takes by weighing quantitative epoxy modified resin, contain the compound modified resin of ethylene linkage, pigment and chemical assistant, and they are dropped in the same container: its two, be to the various batchings in the container, in high-speed stirring with its homodisperse: they are three years old, after the above-mentioned batching that stirs is ground to certain fineness, filter standby.
Wherein the effect of chemical assistant is the dispersion of dissolving that promotes two kinds of resins.
Next is by the embodiment requirement with linking agent, propyl carbinol, butylacetate, high boiling ester fusion together, and as the solvent of modulation insulating enamel paint resisting electric arc: linking agent is wherein mixed by lauroleate and silicic acid fat and is made into; Perhaps also can adopt the mixture of naphthenate.
A component and B component are pressed 1: 2～2.8 proportioning the most at last, can be modulated into the present invention
Described insulating enamel paint resisting electric arc.
Use practice to show: to compare with the external similar coating of anti-electric arc according to insulating enamel paint resisting electric arc provided by the invention, not only reached identical requirement at aspects such as arc resistance energy, electrical insulation properties, and the sticking power index on base-materials such as metal is more skillful, simultaneously owing in raw-material selection, adopt home made materials, thereby low production cost.Really be a kind of novel insulation system material that occurs in high pressure resistant, the anti-electric arc industry of China.
Below provide insulating enamel paint resisting electric arc of the present invention and external like product performance index contrast information slip.
