Abstract

The invention provides a protective coating for a gate valve outer layer and relates to the technical field of valve processing production. The protective coating is characterized by being prepared from materials in parts by weight as follows: 6 parts of bisphenol A epoxy resin, 3 parts of wollastonite powder I, 1 part of sebacic dihydrazide, 1 part of polyvinyl ether, 4 parts of modified asphalt, 3 parts of hexachlorocyclopentadiene, 1 part of sodium benzoate, 2 parts of acetic acid, 2 parts of dicyanodiamide, 2 parts of carboxymethyl cellulose, 3 parts of amino resin, 1 part of wollastonite powder II, 1 part of alkylolamides, 3 parts of nano carbon powder and 9 parts of a finishing agent. The method is reasonable, the operation is convenient, and the ratio is reasonable.

Description

Technical field: [0001] The invention relates to the technical field of valve processing and production, in particular to a protective coating for the outer layer of a gate valve. Background technique: [0002] A valve is a control component in a fluid conveying system, with functions such as cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow pressure relief. [0003] Valves used in fluid control systems, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, have a wide variety 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, dual-phase steel valves, plastic val...
