Embodiment 1

[0011] A solvent-resistant and static-conductive epoxy coating, consisting of two parts A and B, wherein part A consists of epoxy resin 30, pigment and filler 25, conductive material 20, defoamer 0.2, leveling agent 0.5, anti-settling agent 1.3, Diluent 15, Part B is Modified Amine Curing Agent 8.

[0012] The conductive material is inorganic conductive powder.

[0013] The preparation method of the part A is: first add a part of the diluent to the epoxy resin and mix until uniform, then add pigments and fillers, defoamers, leveling agents, anti-sedimentation agents, and grind to a fineness with a sand mill Less than 30 microns, then slowly add the conductive material, and finally add the remaining diluent, and stir well.

[0014] When using, add component B to component A, mix well, and use for coating.

Embodiment 2

[0016] A solvent-resistant and static-conductive epoxy coating, consisting of two parts A and B, wherein part A consists of epoxy resin 40, pigment and filler 20, conductive material 15, defoamer 0.5, leveling agent 1, anti-settling agent 1.5, Diluent 10, Part B is Modified Amine Curing Agent 12.

Embodiment 3

[0018] A solvent-resistant and static-conductive epoxy coating, consisting of two parts A and B, wherein part A consists of epoxy resin 20, pigment and filler 25, conductive material 25, defoamer 0.5, leveling agent 1, anti-settling agent 1.5, Diluent 15, Part B is Modified Amine Curing Agent 12.

[0019] The applicant finds that the control of the composition materials of parts A and B can directly affect the performance of the product through reasonable matching of part A and part B produced by the present invention. The best embodiment of this application is embodiment 2. Before use, A \B part is stored separately, with stable performance and convenient storage. When painting, mix the two and then paint. It has good static conductivity and high solvent resistance (ketone solvents such as cyclohexanone, alcohol solvents such as methanol, Aromatic hydrocarbon solvents such as xylene and ester solvents such as butyl acetate) have strong corrosion resistance and fully meet the ...

Abstract

The invention discloses a solvent-resistant static-conducting epoxy paint which is composed of a part A and a part B. The part A is composed of 20-40 parts of epoxy resin, 10-25 parts of pigment and filler, 15-25 parts of conducting material, 0.2-0.5 part of defoaming agent, 0.5-1 part of leveling agent, 1-1.5 parts of anti-settling agent and 10-15 parts of diluter. The part B is composed of 8-12 parts of modified amine curing agent. The part A and part B are reasonably matched, the epoxy paint is stable in performance and convenient for storage before use; and after being applied, the epoxy paint has the advantages of favorable static conductivity, high solvent resistance and high corrosion resistance, and completely satisfies the application demands for liquid material tanks and pipelines in petroleum and chemical industries.

Description

technical field [0001] The invention relates to an epoxy coating, in particular to a solvent-resistant and static-conducting epoxy coating. Background technique [0002] In the petroleum and chemical industries, the inner surface of liquid raw material storage tanks and pipelines requires coating protection. The coating protection must have the functions of corrosion resistance and antistatic. This coating can greatly prolong the service life of storage tanks or pipelines. Long service life, prevent the combustion or explosion of chemical raw materials caused by static electricity generated by friction. [0003] There are many types of existing epoxy coatings, but few are used in special occasions. In special use environments, the corrosion resistance and solvent resistance and static conductivity of epoxy coatings must meet the needs. keep improving. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the invention provides a solve...
