Problems solved by technology
The problems of this type of coating are: poor oil resistance, corrosion resistance and decoration; electrochemical corrosion of the tank wall of the oil storage tank
[0007] 1. The water resistance is not very good, and the bottom of the oil tank is severely corroded
[0008] 2. It is not suitable for crude oil tanks. When crude oil is extracted from the ground, it is a mixture of oil and water at 60-80 °C, containing O 2 , CO 2 、H 2 S, HCO 3 - 、CL - , SO4 2- 、H + , organic acids and other substances have a strong

Abstract
The invention belongs to the corrosion protective coating technique field and provides an oil resistance (solvent) and temperature resistance electrostatic conducting corrosion protective coating and a preparation method thereof. The coating is mainly made by raw components by weight percentage of 20-35 percent of resinI which is used as basic material, 0-15 percent of modified resin II, 15-30 percent of conductive fillers, 1-3 percent of coupling agent, 8-20 percent of fillers, 10-15 percent of solvent, 2-10 percent of plasticizer, 0.5-1 percent of defoamer, 0.5-1 percent of flatting agent and 6-15 percent of curing agent. The coating is prepared according to the following steps: the resin I, the modified resin II, the coupling agent, the plasticizer, the flatting agent and the defoamer are put in a distributing tank. And part of mixed solvent is added to be stirred and distributed uniformly. The fillers are added proportionally and are put in a sand mill for sand milling after being dispersed and stirred uniformly at high speed, so as to obtain upper grinding pigment paste. The conductive fillers and the rest mixed solvent are added at low stirring speed. The conductive fillers are totally blended into the upper grinding pigment paste and stirring is carried out at middle speed, the viscosity is adjusted to be qualified and the fillers are filtered to obtain a qualified component A product. The curing agent is carried out subpackage according to proportion.
Description
technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and mainly provides an anti-corrosion coating with oil (solvent), temperature resistance and static conduction and a preparation method thereof. Background technique [0002] During the storage and transportation of petroleum products, material friction generates static electricity. In order to prevent oil fire accidents, the country has formulated a series of standards, such as GB 13348 Electrostatic Safety Regulations for Liquid Petroleum Products, GB 6950 Light Oil Safety Electrostatic Conductivity, GB 50393 The technical specification for anti-corrosion engineering of steel oil storage tanks stipulates that oil storage tanks should use static conductive anti-corrosion coatings, and the surface resistivity is required to be 10 8 ~10 11 between Ω. [0003] Static conductive anti-corrosion coatings are divided into intrinsic type and additive type. The intrinsic type is that t...
