Embodiment 1

[0037] A kind of zinc ene anticorrosion paint, is made up of by weight ratio, modified epoxy resin 30%; Functional filler 30%; Zinc powder 15%, graphene 2%, surfactant 5%, xylene 8%, normal Butanol 10%.

[0038] In August 2016, using zinc olefin anti-corrosion coatings, in the Zhengzhou Bridge section of Zhengzhou Railway Bureau, the Longhai Main Line crossed Chengdong Road in Zhengzhou City and the sidewalk steel brackets of the Zijingshan Road Super Bridge to conduct on-site brushing tests. The bridge is located on Longhai downlink bus line K563+989~K565+084, with a total length of 1095m. On-site personnel carry out on-site brushing according to the usage method of the coating, and the specific construction process is the same as that of Example 1. This time, a total of 4 steel brackets were painted with 2kg of zinc olefin anti-corrosion paint.

Embodiment 2

[0040] A kind of zinc ene anticorrosion paint, is made up of by weight ratio, modified epoxy resin 35%; Functional filler 25%; Zinc powder 12%, graphene 2.5%, surfactant 3%, xylene 12.5%, normal Butanol 10%.

[0041] In August of the same year, zincene anti-corrosion coatings were used to carry out field brushing tests in the Xinxiang Bridge Section of Zhengzhou Railway Bureau and on the under-supported steel truss girders of the Beijing-Guangzhou Main Line across the Weihe Bridge. The bridge is located in the direction of heavy vehicles on the Beijing-Guangzhou line, with a central mileage of K597+177. The on-site staff brushed according to the usage method of the paint, and the specific construction process was the same as that of Example 1. This time, a total of 5.5 square meters and a steel bracket were painted with 1.5kg of zinc olefin anti-corrosion paint.

Embodiment 3

[0043] Modified epoxy resin 33.8%; functional filler 22%; zinc powder 20%, graphene 1.4%, surfactant 6%, xylene 6%, n-butanol 10.8%.

[0044] In September 2016, using zinc olefin anti-corrosion coatings, in the Zhengzhou Bridge section of Zhengzhou Railway Bureau, the Longhai Main Line crossed Chengdong Road in Zhengzhou City and the sidewalk steel brackets of the Zijingshan Road Super Bridge to conduct field brushing tests. The bridge is located on Longhai downlink bus line K563+989~K565+084, with a total length of 1095m. On-site personnel carry out on-site brushing according to the usage method of the coating, and the specific construction process is the same as that of Example 1. This time, a total of 8 steel brackets were painted with 4kg of zinc olefin anti-corrosion paint.

Abstract

The invention discloses zinc-alkene anticorrosive paint for steel structure anti-corrosion. The zinc-alkene anticorrosive paint is prepared from, by weight, 10-40% of modified epoxide resin, 20-50% offunctional filler, 0.01-28% of zinc powder, 0.2-3% of graphene, 3-15% of surfactant, 5-25% of xylene and 5-25% of normal butanol. The waterproofness and fast electrical conductivity of nanometer two-dimensional flaky graphene are utilized to apply the graphene to the field of anti-corrosion of railway line bridge equipment steel structure workpieces. Because the used anticorrosive mechanism of the paint is good electrical conductivity of the graphene and lap joint characteristics of the flaky zinc powder, a good conductive layered network structure is formed on the coating surface, the immersion of a corrosive medium is hindered, the physical shielding effect is good, the steel structure workpieces are effectively protected, and the corrosion resistance of the surface of the steel structure workpieces is improved. In addition, the graphene is used to replace parts of zinc powder, not only does the coating have an excellent cathodic protection effect, but also the use amount of the zinc powder is reduced during the preparation of the paint, and the damage and pollution of zinc vapor to the human body are reduced during the processing of later welding.

Description

technical field [0001] The invention relates to the technical field of steel structure anticorrosion, in particular to a zinc ene anticorrosion coating which has anticorrosion effect and is used in steel structure workpieces of railway line bridge equipment. Background technique [0002] Because the steel structure workpiece of railway line bridge equipment works in the open air, the operating environment is complex, and it is subjected to the effects of sunlight, rain, snow and various corrosive substances, and its metal parts are extremely prone to corrosion. Corrosion is one of the main forms of damage to metal structural parts. The failure of components and the corresponding economic losses caused by it are very huge. According to incomplete statistics, from 1999 to 2000, the Ministry of Railways spent 400 million yuan per year on corrosion and protection. yuan or more. According to the "Five Times Law" proposed by American scholars, if the anti-corrosion work is in pla...
