Embodiment approach 1

[0042] Step 1: Hydroxylation of graphene surface

[0043] Utilize 98wt% concentrated sulfuric acid and 65wt% concentrated nitric acid, press Prepare aqua regia according to the ratio; then press m:V 王水 The ratio of =1g:600mL weighs (measures) and gets graphene and aqua regia. The weighed graphene was dispersed in aqua regia and ultrasonically treated in a water bath for 30 minutes. Then the system was heated and stirred in a water bath at 60°C for 6 hours, and the graphene was washed with distilled water until neutral, dried in an oven at 60°C, and ground.

[0044] Step 2: Coupling of Graphene

[0045] The graphene obtained in step one and KH602 (N-β-(aminoethyl)-γ-aminopropylmethyldimethoxysilane), according to m 石墨烯 :m KH-602 =1mg:3mg mass ratio dissolved in a small amount of deionized water, stirred evenly, ultrasonically dispersed for 30min. Thereafter, it was heated and stirred with a magnetic stirrer at 60°C for 8 hours, and the modified graphene was separated by ...

Abstract

The invention discloses a graphene-containing marine anticorrosion antifouling coating and a preparation method thereof. Graphene having an antibacterial function is used as a filling material and is added into epoxy resin by surface modification, and the nano composite antifouling coating having antibacterial and anticorrosion properties is prepared. The graphene is added into the epoxy resin to form the marine antifouling coating; the excellent characteristics of the two materials are fully combined, so the coating has both the antifouling characteristic and the anticorrosion characteristic, that is to say, graphene and the epoxy resin are composited, so the antibacterial property of graphene and the anticorrosion property of the epoxy resin are organically combined jointly, and thus the novel antifouling coating having both the anticorrosion property and the antifouling property is developed.

Description

[0001] The application of the present invention is a divisional application of the parent application "a graphene-containing marine anti-corrosion and antifouling coating and its preparation method". The application number of the parent application is 2013105390377, and the application date of the parent application is November 1, 2013 day. technical field [0002] The invention relates to an antifouling paint for marine metal components and a preparation method thereof, more specifically, to a graphene-containing marine antifouling paint and a preparation method thereof. Background technique [0003] Biofouling is a major problem that has plagued the development of the marine shipbuilding industry for a long time; the research results show that marine fouling caused by marine organisms on the surface of the ship will increase the roughness of the hull surface, reduce the speed of the ship, increase fuel consumption, and will contribute to the future development of the hull. ...
