[0042] Further, the preparation method of high temperature resistant coating comprises the following steps:

[0043] A: First put petroleum resin and solvent into the stirring tank for mixing, control the temperature in the stirring tank at 52°C, set the stirring speed at 120r / min, and stir for 20min, then put in the modified acrylic resin and continue stirring. Stirring time is 10min;

[0044] B: Add resin plasticizer, set stirring speed to 600r / min, stirring time 60min, stir until colorless transparent viscous liquid, then add epoxy resin and continue stirring for 20min;

[0045] C: Then add the configured multi-functional auxiliary agent into the stirring tank and stir evenly, the stirring speed is 550r / min, the stirring time is 60min, and the temperature in the stirring tank is controlled at 35°C;

[0046] D: Finally, add surfactant and complex rare earth and stir for 30 minutes at a stirring speed of 200r / min to obtain a high temperature resistant coating.

Abstract

The invention relates to the technical field of electric appliance cabinets, in particular to a machining method of an electric appliance cabinet. The method comprises the following steps of (1) selecting a galvanized plate as a material for manufacturing a cabinet body; (2) dividing the electric appliance cabinet into a door, a rear shell, a base and a top cover according to the shape of the electric appliance cabinet; (3) cutting the selected galvanized plate according to the preset size, and stamping the cut on a stamping machine and bending to be formed; (4) trimming flashes and burrs of the galvanized plate formed by stamping and bending and forming, and obtaining a semi-finished product of the electric appliance cabinet after the galvanized plate passes inspection; and (5) combiningand installing the qualified semi-finished electric appliance cabinet products, assembling the semi-finished electric appliance cabinet products into a complete electric appliance cabinet, and then carrying out welding and forming. The machining method has beneficial effects that the galvanized plate and the high-temperature-resistant coating are combined to process and manufacture the electric appliance cabinet, so that the electric appliance cabinet not only has good corrosion resistance, but also has good high-temperature resistance, and the service life of the electric appliance cabinet isprolonged.

Description

technical field [0001] The invention relates to the technical field of electric cabinets, in particular to a processing method for electric cabinets. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components; the materials for electrical cabinets are generally divided into two types: hot-rolled steel plate and cold-rolled steel plate; cold-rolled steel plate is softer than hot-rolled steel plate, and is more suitable for electrical appliances. The production of cabinets, electrical cabinets are widely used mainly in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] Chinese Patent No. CN105552759A provides a production process for a power distribution cabinet, including (1) dividing the power distribution cabinet into four parts: a door, a rear shell, a base, and a top ...
