Electrostatic spraying antirust oil and preparation method thereof

Abstract

The invention belongs to the field of metal surface protection and provides electrostatic spraying antirust oil and a preparation method thereof. The antirust oil is prepared from the following ingredients in parts by weight: 5 to 15 parts of oxidized petroleum wax salt, 0 to 5 parts of synthesized ammonium sulfonate and 35 to 90 parts of hydrorefined mineral oil, wherein the oxidized petroleum wax salt is at least one of calcium salt of oxidized petroleum wax, sodium salt of the oxidized petroleum wax or ammonium salt of the oxidized petroleum wax, and the base number of the oxidized petroleum wax salt is 100 to 500 mgKOH / g; the hydrorefined mineral oil is at least one of refined mineral oil with the viscosity of 5 mm<2> / s under 40 DEG C, refined mineral oil with the viscosity of 32 mm<2> / s under 40 DEG C or refined mineral oil with the viscosity of 68 mm<2> / s under 40 DEG C. The antirust oil disclosed by the invention has good environmental protection property and in the meantime, has a reasonable resistance value; the resistance value is only 0.1 to 20 M omega under the temperature of 20 to 60 DEG C; the antirust oil is suitable for electrostatic atomization spraying of metal, can form an even oil film on the plate surface, which cannot be broken down to generate electric spark to be combusted, and has high use safety; furthermore, the antirust performance is excellent, lowtemperature resistance of the product is good, and good fluidity can be achieved under the -20 DEG C environment.

Description

technical field [0001] The invention belongs to the field of metal surface protection, and in particular relates to an antirust oil by electrostatic spraying and a preparation method thereof. Background technique [0002] The damage of metals under atmospheric conditions, mainly due to electrochemical action, is customarily called rust. According to survey results, economic losses caused by metal corrosion in countries around the world account for about 2% to 4% of their national economic output. Because the anti-rust technology of each company, industry or country is very different, this data can only be used as an average reference value. In recent years, due to the vigorous development of automobile, real estate, infrastructure and other industries, the demand and use of steel have increased dramatically, and the consumption of anti-rust oil has also increased accordingly. [0003] my country's anti-rust oil products have formed a scale, with an annual output of more th...
