Problems solved by technology

Although most of the electrical equipment is installed outdoors, and the coating layer contains a large amount of organic matter, and the coating layer will age under natural conditions, the function of the coating layer will be lowered, which will lead to electrical equipment failure. Corrosion will occur in the outer casing, which also makes it difficult to guarantee the safety of electrical equipment

Abstract

The invention discloses an insulating anti-aging coating for a unit ring network cabinet and a preparation method thereof. The method comprises: 1) mixing polyether glycol, diisocyanate, expanded vermiculite, zinc borate, 4-amino- 1,2,4-triazole, silica sol, ethyl acetate and tungsten disulfide are subjected to a contact reaction under vacuum conditions to obtain component one; 2) ethylene-vinyl acetate emulsion, polyether triol , inorganic salt whisker, lead naphthenate, hydroquinone, diatomaceous earth, aluminum oxide fiber and alkylsulfonic acid alcohol ether carry out contact reaction under the existence of ultraviolet light to make component two; 3) will Component 1 is mixed with Component 2, followed by adding bone glue, urea, asphalt and silicon dioxide for ultrasonic vibration to prepare an insulating anti-aging coating. The insulating anti-aging coating prepared by the method has excellent insulating properties and anti-aging properties, thereby making the insulating anti-aging coating suitable for unitary ring network cabinets. At the same time, the preparation method has simple procedures, easy-to-obtain raw materials, and is convenient for mass production.

Description

technical field [0001] The invention relates to a paint, in particular to an insulating and anti-aging paint for a unit ring network cabinet and a preparation method thereof. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. Among them, the unit type ring network cabinet (switch cabinet) is a typical electrical equipment. [0003] In order to protect the shell of the unit type ring network cabinet, in the prior art, paint is generally sprayed on the surface of the cabinet body of the unit type ring network cabinet to form a coating layer so as to prevent the corrosion of the shell of the unit type ring network cabinet and at the same time Anti-insulation effect. Although most of the electrical equipment is installed outdoors, and the coating layer contains a large amount of organic matter, and the coating layer will age under natural conditions, the funct...
