Abstract

The invention relates to a rust-proof paint for flowmeters and its preparation method thereof. The rust-proof paint comprises that following ingredients by mass: 20-30 parts of silicone-acrylic emulsion, 10-20 parts of resin, 1-2 parts of butyl acetate, 0.8-2 parts of silicone oil, 2-4 parts of potassium dihydrogen phosphate, 5-10 parts of bentonite, 6-10 parts of phosphor titanium powder, 2-4 parts of acrylic acid, 1-3 parts of zinc oxide, and 0.1-0.6 part of calcium fluorophosphate. The invention has the advantages that the paint with excellent rust prevention performance is prepared, the surface of the flowmeter is not corroded, and the flowmeter can be used for a long time.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to a paint with excellent antirust performance and a preparation method thereof. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. Flow measurement is widely used in various fields of industrial and agricultural production, national defense construction, scientific research, foreign trade and people's life. Flowmeter is a commonly used instrument for flow measurement. The working environment where the flowmeter is located is often full of various oily and corrosive substances. It is difficult to meet its performance requirements with general rust prevention. Therefore, there are higher requirements for the paint used on the surface of the flowmeter shell. . Contents of the invention [0003] In order to solve the above-mentioned technical problems, the...
