Abstract

The invention provides a waterproof coating for an electromechanical device and a preparation method thereof. The waterproof coating for the electromechanical device is prepared from the following components: bentonite powder, a mixed acid solution, a modified acrylate emulsion, organic rubber, a polyurethane material, a composite additive, modified calcium carbonate, sodium lignin sulfonate, alkylphenol ethoxylates, glyceryl tristearate, softening oil, a low temperature resistant modifier, an emulgator, a water reducer, a thickening agent and deionized water. The waterproof coating prepared through the invention has the excellent characteristics of cold resistance, heat resistance, aging resistance, environment protection, long service life and the like, and is wide in application range and convenient to apply, meanwhile, raw materials are wide in source and easy to get, no harmful substances is generated during the preparation process, the energy consumption is greatly reduced, and an effect on cleaner production is achieved.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a waterproof coating for electromechanical equipment and a preparation method thereof. Background technique [0002] At present, there are two kinds of waterproof materials used for electromechanical equipment: one is rigid waterproof; the other is flexible waterproof. Among them, the commonly used rigid waterproof is to add a concrete mortar waterproof layer on the base surface of the electromechanical equipment. This kind of waterproof layer is not tightly combined with the base surface, and the waterproof layer itself has molecular voids, which are easy to corrode and expand under the action of water, resulting in cracking of the waterproof layer and losing the anti-corrosion and water-leakage effects. Similarly, the flexible waterproofing commonly used at present is to brush organic waterproof coatings on the base surface of the water supply equipmen...
