preparation example Construction

[0028] Based on the same invention, the application also provides a preparation method of a graphene composite antirust agent, see attached figure 1 , including the following steps:

[0029] S1: Pretreatment of styrene;

[0030] S2: Mix natural chlorinated rubber, lithium-based bentonite, carboxymethyl cellulose and water for the first stirring, and obtain an intermediate mixture after uniformity;

[0031] S3: Add the pretreated styrene to the intermediate mixture for the second stirring, and obtain a chlorinated rubber aqueous emulsion after being uniform;

[0032] S4: adding graphene to the aqueous emulsion of chlorinated rubber to obtain the finished product of the graphene composite antirust agent.

[0033] Further, the pretreatment of styrene in step S1 is as follows: the styrene is washed with alkali for 3 to 5 times by NaOH solution with a mass fraction of 5%; after the alkali washing is completed, the styrene is washed with water for 3 to 5 times until neutral .

...

Embodiment 1

[0037] S1: Wash the styrene four times with NaOH solution with a mass fraction of 5%; after the alkali washing is completed, wash the styrene four times with water until neutral;

[0038] S2: Mix 9% natural chlorinated rubber, 2.6% lithium-based bentonite, 2.2% carboxymethyl cellulose and 65.2% water for the first stirring, control the speed at 800r / min, and control the time at 15min, and obtain intermediate mixing after uniformity liquid;

[0039] S3: Add the pretreated 21% styrene to the intermediate mixture for the second stirring, control the rotation speed to 800r / min, and control the time to 18min to obtain a chlorinated rubber aqueous emulsion;

[0040] S4: Adding 0.05% graphene by mass to the aqueous emulsion of chlorinated rubber to obtain a finished graphene composite antirust agent.

Embodiment 2

[0042] S1: Wash the styrene four times with NaOH solution with a mass fraction of 5%; after the alkali washing is completed, wash the styrene four times with water until neutral;

[0043] S2: Mix 11% natural chlorinated rubber, 3% lithium-based bentonite, 2.8% carboxymethyl cellulose and 63.2% water for the first stirring, control the speed at 800r / min, and control the time at 15min, and obtain intermediate mixing after uniformity liquid;

[0044] S3: Add the pretreated 20% styrene to the intermediate mixture for the second stirring, control the rotation speed to 800r / min, and control the time to 18min to obtain a chlorinated rubber aqueous emulsion;

[0045] S4: Adding 0.1% graphene by mass to the aqueous emulsion of chlorinated rubber to obtain a finished graphene composite antirust agent.

Abstract

The invention relates to a graphene compound antirust agent and a preparation method thereof. The graphene compound antirust agent comprises chlorinated rubber water-based emulsion and graphene; the ratio of graphene to chlorinated rubber water-based emulsion is 0.01-0.16%; the chlorinated rubber water-based emulsion is prepared from the following components in percentage by weight: 8%-12% of natural chlorinated rubber, 2.5%-3.5% of lithium bentonite, 2%-3.5% of carboxymethyl cellulose, 18%-25% of styrene and 60%-70% of water. After the graphene compound antirust agent is coated on the surfaceof power equipment, a good anti-corrosion effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of electric equipment anticorrosion, in particular to a graphene composite antirust agent and a preparation method thereof. Background technique [0002] The southern area is humid, especially in coastal areas with high salt density and some heavy industrial gas pollution areas, such as power plants, ceramic factories, cement factories and other heavily polluted areas. Outdoor electrical equipment and their metal structures are in harsh environments all year round, subject to sunlight, humidity, The influence of various external factors such as temperature, acid, alkali, salt, etc., has a certain impact on its outer surface or material, and the serious one is called corrosion. [0003] In electrical equipment, for example, the iron in the equipment frame or transmission part corrodes and becomes iron oxide, which separates layer by layer, resulting in transmission jamming. The copper in the conductive part ...
