High temperature resistant and corrosion resistant coating for surface of distribution box and preparation method of high temperature resistant and corrosion resistant coating

Abstract

The invention discloses a high temperature resistant and corrosion resistant coating for the surface of a distribution box and a preparation method of the high temperature resistant and corrosion resistant coating. The high temperature resistant and corrosion resistant coating for surface of the distribution box is prepared from the following raw materials in parts by weight: 50 to 80 parts of epoxy resin modified organic silicon resin, 10 to 20 parts of dimethylbenzene, 5 to 15 parts of propylene glycol, 5 to 8 parts of zinc naphthenate, 3 to 8 parts of tributyltin chloride, 3 to 5 parts of barium petroleum sulfonate, 3 to 10 parts of kerosene, 6 to 10 parts of lauryl diethanolamine, 2 to 8 parts of p-methylaniline, 5 to 8 parts of zinc powder, 3 to 6 parts of silicon nitride, 5 to 8 parts of chromium carbide, 5 to 10 parts of aluminium-plated glass micro-beads, 6 to 15 parts of silicon dioxide, 5 to 8 parts of aluminium oxide, 3 to 5 parts of calcium sulphate whisker powder, 5 to 10 parts of polytetrafluoroethylene, 5 to 10 parts of aloe juice, 10 to 20 parts of filler, 5 to 15 parts of pigment, 3 to 5 parts of a cardanol modified amine curing agent, 1 to 3 parts of a levelling agent, and 1 to 3 parts of an antifoaming agent. According to the high temperature resistant and corrosion resistant coating for the surface of the distribution box and the preparation method of the coating, reasonable raw materials and proportions are selected, so that the coating is dense and neat, does not crack, does not swell, does not fall off, and has high resistance to high temperature and corrosion; normal work of a distribution box is ensured; and the service life of the distribution box is prolonged.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a high-temperature-resistant and corrosion-resistant coating on the surface of a distribution box and a preparation method thereof. Background technique [0002] The distribution box is a kind of electrical equipment, and it is the main control center in the circuit. The distribution box is often installed in the open air, and the heat generated inside the distribution box itself, coupled with the external sunlight exposure, is likely to cause the surface temperature of the box to rise. Higher, if ordinary paint is used on the surface of the box, cracking, swelling, and falling off may occur at high temperatures. Furthermore, the external rainwater is highly corrosive, and the corrosion resistance of ordinary paint is not good, which may easily cause the box to The body is severely corroded, shortening the service life of the distribution box.
