Problems solved by technology

However, during the storage and transportation of methanol gasoline, the acid corrosion and electrochemical corrosion of metals are activated due to the presence of moisture. At present, the internal anti-corrosion coatings used alone for gasoline storage tanks or methanol storage tanks cannot meet the requirements of methanol gasoline storage tanks. Anti-corrosion requirements

Embodiment 1

[0017] Weigh the following ingredients in proportion:

[0018] A component

[0019]

[0020]

[0021] B component

[0022] Curing agent D9050 5.5kg

[0023] Curing agent D9340 5.5kg

[0024] Take n-butanol, which is half of the formula amount, and add it to the mixture of bisphenol F epoxy resin and epoxy novolac resin, and stir evenly. After adding the formula amount of dispersant, defoamer and leveling agent, then add the formula amount of pigments and fillers titanium dioxide, zinc phosphate and mix well, then grind it on a sand mill to a fineness of 30 μm, and add anti-sedimentation agent after the fineness is qualified Polyamide wax, slowly add the formulated amount of static conductive filler. Finally, add the remaining n-butanol and stir evenly to obtain component A. Component B is obtained by uniformly mixing D9050 and D9340 according to the formula amount. When in use, slowly add component B to component A and stir evenly to obtain the final product.

Embodiment 2

[0026] Weigh the following ingredients in proportion:

[0027] A component

[0028]

[0029] B component

[0030] Curing agent D9050 11kg

[0031] The preparation method is the same as in Example 1.

Embodiment 3

[0033] Weigh the following ingredients in proportion:

[0034] A component

[0035]

[0036]

[0037] B component

[0038] Curing agent D9050 5.5kg

[0039] Curing agent D9340 3.5kg

Abstract

The invention discloses a methanol-gasoline-resisting static-electricity-conducting anticorrosive paint, which is prepared by the following raw materials according to weight: a component A consisting of 25-39 parts of epoxy resin, 5-20 parts of pigment and filler, 15-28 parts of static-electricity-conducting filler, 0.2-2 parts of carbon nanotubes, 0.3-1 part of cinnamyl aldehyde, 2-6 parts of auxiliaries, and 5-16 parts of diluent, and a component B consisting of 7-11 parts of modified aromatic aliphatic amine hardener. According to the invention, the epoxy resin is formed by epoxy phenolic resin and bisphenol F-type epoxy resin according to a weight ratio of 3:(1-3), and the modified aromatic aliphatic amine hardener is one out of D9050 and D9340 or the mixture of the two. According to the invention, the component A and the component B are prepared first respectively. When in use, the component B is slowly added into the component A to be stirred uniformly to obtain a final product. The anticorrosive paint prepared in the invention can resist permeation and corrosion of strong solvents, and free particles cannot be separated out from the methanol gasoline after long-term storage, thereby preventing influence resulted by storage to the quality of a finished oil product.

Description

technical field [0001] The invention relates to a paint, in particular to a methanol-gasoline-resistant, static-conductive, anti-corrosion paint. Background technique [0002] The release of the national standard for methanol gasoline for vehicles has created good conditions for the large-scale promotion and application of methanol gasoline. However, during the storage and transportation of methanol gasoline, the acid corrosion and electrochemical corrosion of metals are activated due to the presence of moisture. At present, the internal anti-corrosion coatings used alone for gasoline storage tanks or methanol storage tanks cannot meet the requirements of methanol gasoline storage tanks. Anti-corrosion requirements. Therefore, it is necessary to provide an electrostatically conductive coating that can resist the strong swelling of methanol and gasoline corrosion, and at the same time ensure that the oil is not subject to secondary pollution of the coating, so as to meet the...
