Problems solved by technology

However, traditional anti-corrosion coatings have problems such as large environmental pollution, single anti-corrosion effect, and poor anti-corrosion effect, which make them unable to meet the needs of industry development. Therefore, it is imperative to develop a new type of high-efficiency anti-corrosion coating.
The anti-corrosion filler in some existing graphene-based anti-corrosion coatings is mainly pure graphene, which has a single component and only plays a certain barrier effect, and the anti-corrosion performance is not significantly improved, thus limiting its application range

Embodiment 1

[0019] Proportioning each component according to the following mass percentages:

[0020]

[0021] (1) Put 300g of graphene powder into a fluidized bed reactor, feed nitrogen into the reactor as a protective gas to increase the material layer to 1 / 4 of the bed, preheat to 500°C, and keep warm for 20min;

[0022] (2) Increase the reactor temperature to 650°C, add zinc powder to the reactor to continuously vaporize it at high temperature, and become zinc vapor. The amount of zinc powder added is 3 times that of graphene powder, and the amount of protective gas is adjusted. The flow rate increases the material layer to 1 / 2 of the bed layer;

[0023] (3) After the zinc powder is completely vaporized, continue the reaction for 1 hour, during which the temperature is lowered to 150°C at a constant speed, and the heating is stopped after 30 minutes of heat preservation, and the nitrogen gas is continued until the material is cooled. The material obtained after the reaction is cru...

Embodiment 2

[0026] Proportioning each component according to the following mass percentages:

[0027]

[0028]

[0029] (1) Put 300g of graphene powder into a fluidized bed reactor, feed nitrogen into the reactor as a protective gas to increase the material layer to 1 / 3 of the bed, preheat to 500°C, and keep warm for 30min;

[0030] (2) Increase the reactor temperature to 650°C, add zinc powder into the reactor to continuously vaporize it at high temperature, and become zinc vapor. The amount of zinc powder added is 3.5 times that of graphene powder, and the amount of protective gas is adjusted. The flow rate increases the material layer to 1 / 2 of the bed layer;

[0031] (3) After the zinc powder is completely vaporized, continue the reaction for 1 hour, during which the temperature is lowered to 160°C at a constant speed, and the heating is stopped after 20 minutes of heat preservation, and the nitrogen gas is continued until the material is cooled. The material obtained after the...

[0034] Proportioning each component according to the following mass percentages:

[0035]

[0036]

[0037] (1) 300g of graphene powder is loaded into a fluidized bed reactor, and nitrogen gas is introduced into the reactor as a protective gas to increase the material layer to 1 / 3 of the bed layer, preheat to 550° C., and keep warm for 20 minutes;

[0038] (2) Increase the reactor temperature to 700°C, add zinc powder to the reactor to continuously vaporize it at high temperature, and become zinc vapor. The amount of zinc powder added is 4 times that of graphene powder, and the amount of protective gas is adjusted. The flow rate increases the material layer to 1 / 2 of the bed layer;

[0039] (3) After the zinc powder is completely vaporized, the reaction is continued for 1 hour, during which the temperature is lowered to 160°C at a constant speed, and the heating is stopped after 30 minutes of heat preservation, and the nitrogen gas is continued until the material is cool...

Abstract

The invention belongs to the field of preparation of anticorrosive paint, and in particular relates to anticorrosive paint added with a graphene/zinc composite material and a preparation method of the anticorrosive paint. The anticorrosive paint is prepared from the following components (in weight percentage composition): 20 to 90 percent of polyurethane, 5 to 15 percent of graphene/zinc composite material, 1 to 10 percent of tinting pigment, 5 to 10 percent of filler, 0.1 to 3 percent of dispersing agent, 0.1 to 3 percent of wetting agent, 0.1 to 3 percent of thickener, 0.1 to 1 percent of flatting agent, 0.1 to 1 percent of defoamer, 0.1 to 1 percent of bactericide and 1 to 35 percent of water. The anticorrosive paint prepared by the preparation method is excellent in anticorrosive effect, harmless to the environment, simple in process, and is prone to industrial production.

Description

technical field [0001] The invention belongs to the field of anticorrosion paint preparation, and in particular relates to an anticorrosion paint added with a graphene / zinc composite material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the country and the rapid construction of cities, a large number of metal materials have been used in infrastructure, energy, chemical industry, construction, transportation and other fields, and the ensuing metal corrosion has become more and more serious. It has brought a lot of inconvenience to people's work and life, and caused huge losses to the national economy. However, traditional anti-corrosion coatings have problems such as large environmental pollution, single anti-corrosion effect, and poor anti-corrosion effect, which make them unable to meet the needs of industry development. Therefore, it is imperative to develop a new type of high-efficiency anti-corrosion coati...
