Powerful anti-aging coating for shell of electric control cabinet and preparation method of powerful anti-aging coating

Abstract

The invention provides a powerful anti-aging coating for a shell of an electric control cabinet and a preparation method of the powerful anti-aging coating, and relates to the technical field of electric control cabinet production. The anti-aging coating is prepared from the following raw materials in parts by weight: 45-55 parts of novolac epoxy, 2-3 parts of nano-tungsten trioxide, 0.8-1.2 partsof a cross-linking agent, 10-15 parts of vinylite, 5-10 parts of polymethyl acrylate, 15-20 parts of an organic solvent, 8-12 parts of 2,6-di-tert-butylphenol, 4-6 parts of N-phenyl-alpha-naphthylamine, 6-10 parts of distearyl pentaerythrityl diphosphite, 3-5 parts of bi-salicylidene diamine, 6-8 parts of poly-p-xylylene, 4-6 parts of polydimethylsiloxane, 2-4 parts of nano-silica, 3-5 parts of clays and 2-4 parts of a thickener. According to the powerful anti-aging coating for the shell of the electric control cabinet and the preparation method of the powerful anti-aging coating, the shortcomings of the prior art are overcome, the anti-aging performance of the coating can be effectively improved, heat resistance of the coating can further be effectively improved, the coating is preventedfrom aging under the action of external light, heat and oxygen and then thawing, powdering, falling off and the like, the overall performance of the coating is excellent, the protection effect is good, the service life is long, and the powerful anti-aging coating is suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of production of electric control cabinets, in particular to a powerful anti-aging coating for the shell of an electric control cabinet and a preparation method thereof. Background technique [0002] Electric control cabinet is to assemble switchgear, measuring instrument, protective device and auxiliary equipment in closed or semiclosed metal cabinet or on screen width according to electrical wiring requirements, and its layout should meet the requirements of normal operation of power system, and is easy to overhaul and does not endanger people. Safety control cabinet (box) for personal and surrounding equipment. Including (distribution cabinet) (distribution box) (electrical control cabinet), etc., the circuit can be connected or disconnected by manual or automatic switch during normal operation. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal ...

AI Technical Summary

Problems solved by technology

At present, the anti-aging performance of the paint used for the electric control cabinet shell is poor, so the paint is very easy to age under the influence of external light, heat, and oxygen, and then occurs pulverization, falling off, etc., making it difficult to continue to protect the electric control cabinet shell. short service life
