Embodiment 1

[0033] The preparation steps of coating of the present invention are as follows:

[0034] (1) Weigh each component according to the distribution ratio of each component specified in Table 1, and set aside;

[0035] (2) Add the graphene nano-chips in step (1) into the ethanol solution at a mass ratio of 1:100, and then put it into an ultrasonic dispersion device for ultrasonic dispersion for 3h-5h, then take it out and filter to obtain a graphene filter sample;

[0036] (3) Dry the graphene filter sample in step (2) at 100°C, then mix with part of the solvent weighed in step (1) at a volume ratio of 1:2, and ultrasonically disperse for 1h-3h, take out stand-by;

[0037] (4) Put the fluorocarbon resin and the remaining solvent weighed in step (1) into the ball mill tank, grind and mix and stir for 0.5h-2h, add dispersant, leveling agent, defoamer and adhesion promoter;

[0038] (5) Add the graphene solvent mixture prepared for use in step (3) into the ball mill tank in step (...

Abstract

The invention provides a novel anti-corrosion, anti-ultraviolet, anti-bacteria and wear-resistant paint and a preparation method for the same. The novel anti-corrosion, anti-ultraviolet, anti-bacteria and wear-resistant paint is composed of an agent A and an agent B, wherein the agent A is composed of the following components in percentage by weight: 60-70% of fluorocarbon resin, 1-8% of graphene nanometre micro-sheets, 0-2% of an ultraviolet absorber, 0.5-1% of a dispersing agent, 0.5-1% of a levelling agent, 0.5-1% of a defoaming agent, 1-3% of bentonite, 20-25% of titanium dioxide, 0.5-1% of an adhesion promoter and 2-5% of a solvent; and the agent B is a curing agent used with the agent A. The preparation method provided by the invention is simple in operation and preparation processes; the prepared graphene anti-corrosion paint is excellent in wear-resistant, ageing-resistant, anti-bacteria and anti-corrosion performances; and moreover, graphene has no toxic and side effects, as well as is efficient and environment-friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a novel anti-corrosion, anti-ultraviolet, anti-bacteria and wear-resistant coating and a preparation method thereof. Background technique [0002] Four-fifths of the earth's surface is covered by oceans, and marine economy and marine industry play an extremely important role in the development of human society. The marine environment is a very harsh and corrosive environment. Ships have been in such a marine environment for a long time, and the corrosion is extremely serious, and coatings have always been the most important anti-corrosion means. Marine anticorrosion and antifouling coatings form the basis of marine coatings. In order to solve these two major problems, marine coatings are designed according to the use environment and requirements of various facilities, and various series of products are derived, such as marine coatings, heavy-duty anti-corrosion coatings for marine engine...
