Problems solved by technology

In addition, conventional antifouling coatings generally have the following problems, that is, the amount of antifouling elements contained in the antifouling coating is large, the release rate is small, and it is difficult to control; the copper penetration rate decreases with time
If the copper penetration is too fast, the anti-fouling life will be short, and marine facilities such as ships will be frequently maintained; if it is too slow, the desired anti-fouling effect will not be achieved.
So far, there are no relevant reports that can solve the problem of controlling the release of antifouling agents in coatings for marine facilities

[0034] The glass raw materials used when being melted into 100g molten glass are respectively: 87.3g of boric acid; 25.2g of quartz sand; 26.0g of soda ash; 15.1g of cuprous oxide; Input into the kiln for high-temperature melting, mechanical blo...

Embodiment 2

[0041] The raw material component (weight) that is made into 100g antifouling paint is:

[0042] Flake glass 30g, acrylic resin 25g, rosin 5g, asphalt 5g, xylene 10g, bentonite 5g, talcum powder 5g, iron oxide red 10g, zinc oxide 5g;

[0043] Among them, the fineness of bentonite used is 230 mesh; the fineness of talc powder is 400 mesh; the fineness of iron oxide red is 540 mesh; zinc oxide produced by indirect method; barium sulfate is precipitated barium sulfate.

[0044] The manufacturing method of the flake glass in this example is basically the same as the method in embodiment 1, and will not repeat them here;

[0045] The difference is that the weight percentage of the glass component contained in the flake glass used is: B 2 o 3 50wt%; SiO 2 20wt%; Na 2 O 10wt%; Cu 2 O 20wt%; the glass flakes used have a thickness of 5 μm and a diameter of 0.2 mm.

[0046] The glass raw materials used when melting into 100g of molten glass are: 97.0g of boric acid; 20.1g of quart...

Embodiment 3

[0050] The raw material component (weight) that is made into 100g antifouling paint is: flake glass 40g acrylic resin 15g, rosin 2g, asphalt 7g, xylene 15g, bentonite 4g, barium sulfate 3g, talcum powder 3g, iron oxide red 5g, zinc oxide 6g;

[0051] Wherein, the fineness of the bentonite used is 325 meshes; the fineness of the talcum powder used is 540 meshes; the fineness of the iron oxide red used is 800 meshes; the zinc oxide is produced by an indirect method; the barium sulfate is precipitated barium sulfate.

[0052] The manufacturing method of the flake glass in this example is basically the same as the method in embodiment 1, and will not repeat them here;

Abstract

The invention discloses an antifouling paint for ships and marine facilities, which contains the following components in weight percent: 30-45wt% of flake glass; 15-25wt% of acrylic resin; 0-5wt% of rosin; 5-10wt% of asphalt %; xylene 5-15wt%; bentonite 3-5wt%; barium sulfate 0-5wt%; talcum powder 2-5wt%; iron oxide 2-10wt%; zinc oxide 5-8wt%. The glass flakes used can control the release rate of Cu+ by adjusting the formula ratio of the glass composition, or adjusting the percentage of glass flakes in the antifouling coating; , slow and stable release of copper ions; the formed paint film has significant anti-fouling and anti-algae capabilities, which can prevent marine organisms from adhering to the surface of ships and marine facilities, effectively improving the protection of the paint surface of ships and marine facilities, and without Toxic and environmentally friendly.

Description

technical field [0001] The invention relates to a coating, in particular to an antifouling coating for ships and marine facilities. Background technique [0002] Marine biofouling brings great harm to ships and all marine facilities. The role of antifouling coatings is to prevent marine biofouling. Antifouling paint or antifouling paint is a special paint that controls or prevents the growth of marine organisms on surfaces exposed to the marine environment, prevents fouling of marine attached organisms, and keeps the bottom of the ship clean. Antifouling coatings are composed of base materials, antifouling agents, fillers, additives and solvents. Among them, the antifouling agent and the base material are the key components to determine the performance of the antifouling coating, and the antifouling agent is an effective component for the antifouling coating to achieve antifouling performance. [0003] The use of cuprous oxide as an antifouling agent in antifouling coatin...
