Abstract

The invention discloses outer protective paint of a plug valve and relates to the technical field of valve machining production. The outer protective paint is characterized by being prepared from, by weight, 2 parts of tetraethoxysilane, 6 parts of bisphenol A epoxy resin, 3 parts of wollastonite in powder, 1 part of sebacic acid dicarbonyl dihydrazide, 1 part of chitosan, 2 parts of calcium metasilicate, 1 part of 8-hydroxyquinoline, 2 parts of defoamer, 2 parts of tetrabutyl titanate, 1 part of acetylsalicylic acid, 1 part of butyl acetate, 8 parts of isophorone diisocyanate, 1 part of thermal conductive fiber, 2 parts of oxalic acid and 3 parts of mixture. A method is reasonable, operation is convenient, and matching is reasonable.

Description

Technical field: [0001] The invention relates to the technical field of valve processing and production, in particular to an outer protective paint for a plug valve. Background technique: [0002] A valve is a control component in a fluid delivery system, with functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion, or overflow pressure relief. [0003] Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves,...
