Embodiment 1

[0010] Put 21 parts of glycerol triacetate and 21 parts of isocyanate into the reaction kettle and mix them. The mixing time is 1 hour, the mixing temperature is 50 degrees, and the mixing speed is 120 r / min. After mixing, add 12 parts of liquid paraffin and continue stirring for 30 minutes. , and then add 7 parts of talcum powder, 10 parts of kaolin and 5 parts of titanium dioxide, the mixing temperature is 60 degrees, and the mixing speed is 140 r / min, until the mixing is uniform, then naturally cool to room temperature.

Embodiment 2

[0012] Put 35 parts of glycerol triacetate and 35 parts of isocyanate into the reaction kettle and mix them. The mixing time is 1.5 hours, the mixing temperature is 60 degrees, and the mixing speed is 120 r / min. After mixing, add 22 parts of liquid paraffin and continue stirring 30 minutes, then add 10 parts of talcum powder, 9 parts of kaolin and 5 parts of titanium dioxide, the mixing temperature is 65 degrees, the mixing speed is 140r / min, until the mixing is uniform, then naturally cool to room temperature.

Embodiment 3

[0014] Put 25 parts of glycerol triacetate and 15 parts of isocyanate into the reaction kettle and mix them. The mixing time is 2 hours, the mixing temperature is 55 degrees, and the mixing speed is 140 r / min. After mixing, add 9 parts of calcium stearate and continue Stir for 30 minutes, then add 3 parts of talcum powder, 2 parts of kaolin and 1 part of titanium dioxide, the mixing temperature is 65 degrees, the mixing speed is 130r / min, until the mixture is uniform, then naturally cool to room temperature.

[0015] Beneficial effects: the present invention adopts a new type of formula, adopts unique formula components to achieve effective waterproofing, and the waterproof coating prepared by the present invention can effectively prevent water from penetrating into the inner end of the busway, avoid electrical short circuit, cause busbar explosion, and improve safety performance.

Abstract

The invention discloses a process for producing a waterproof coating material for a high-voltage waterproof bus. A preparation method for the waterproof coating material comprises the following steps of mixing glycerol triacetate and isocyanate in a reactor for 1-2 hours at the mixing temperature of 50-60 DEG C and the mixing rate of 120-140 r / min, then, adding a dispersant into the mixture, continuing to stir the mixture for 30 minutes, then, adding talcum powder, kaolin and titanium dioxide into the stirred mixture, carrying out mixing at the mixing temperature of 60-65 DEG C and the mixing rate of 130-140r / min until the mixture is uniformly mixed, and then, naturally cooling the mixture to normal temperature, thereby preparing the waterproof coating material. By adopting the waterproof coating material prepared by the method, the occurrence of bus explosion caused by electrical short circuit due to the fact that water penetrates into the inner end of a bus duct can be effectively avoided, and the safety performance is improved.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a production process of a waterproof coating for a high-voltage waterproof busbar. Background technique [0002] Modern high-rise buildings and large workshops require huge amounts of electrical energy, and in the face of the huge loads requiring hundreds of thousands of amperes of strong current, safe and reliable conduction equipment must be selected. The busway is a power distribution device for efficient current transmission, especially to meet the needs of economical and reasonable wiring of increasingly taller buildings and large-scale factories. However, the busway is a kind of electrical equipment, and the occurrence of water immersion is not allowed. In general, when the busway is in use, in case of water seepage, etc., the water is often not discharged in time, causing the entire system to short circuit or explode. Contents of the invention [0003] The technical problem to be...
