Problems solved by technology

According to research, there are as many as 2,000 species of common marine fouling organisms, the most common being algae, hydra, barnacles, oysters, etc. Their attachment has caused great harm to ships and marine facilities, and seriously hindered the development of marine economy
Marine bio-adhesion will lead to an increase in the weight of the hull and sailing friction, and an increase in power and fuel consumption. According to statistics, the fuel consumption caused by marine fouling can increase by up to 40%, and the total cost of the voyage can increase by up to 77%.

preparation example Construction

[0025] The preparation method of special antifouling paint for ships provided by the invention may further comprise the steps:

[0026] Step S110: Mix and stir polysilane-modified epoxy resin, titanium dioxide, and mica powder to obtain a resin mixture, wherein the mass ratio of the titanium dioxide, mica powder, and polysilane-modified epoxy resin is 1:2:1 -1:4:2;

[0027] Specifically, the resin mixture is obtained after mixing and stirring the polysilane-modified epoxy resin, titanium dioxide, and mica powder, the stirring speed is 1000-1500 rpm, and the stirring time is 1-2 h.

[0028] In some preferred embodiments, the polysilane-modified epoxy resin is prepared by the following method: mixing and stirring silane KH-550 and epoxy resin to form a polysilane-modified epoxy resin, wherein the silane The volume ratio with epoxy resin is 1:10-1:15.

[0029] Step S120: Mix and stir the resin mixture, polytetrafluoroethylene, silicone oil, iron oxide red and rosin to obtain co...

Embodiment 1

[0035] Add 10g of silane KH550 to 100g of epoxy resin, stir at 1000rpm for 1h to form polysilane epoxy resin; then add 200g of mica powder and 100g of titanium dioxide to 100g of polysilane epoxy resin, stir at 1000rpm for 1h to disperse; Then add 25g polytetrafluoroethylene, 25g silicone oil, 5g iron oxide red, 5g rosin, stir at 1000rpm for 2h to obtain component A; mix component A and component B (triethylenetetramine) according to the mass ratio of 5:1 Than use, get special antifouling paint for ships.

Embodiment 2

[0037] Add 10g of silane KH550 to 100g of epoxy resin, stir at 1000rpm for 1h to form polysilane epoxy resin; then add 100g of mica powder and 100g of titanium dioxide to 100g of polysilane epoxy resin, stir at 1500rpm for 1h to disperse; Then add 30g polytetrafluoroethylene, 20g silicone oil, 5g iron oxide red, 5g rosin, stir at 1500rpm for 1h to obtain component A; mix component A and component B (triethylenetetramine) according to the mass ratio of 7:1 Than use, get special antifouling paint for ships.

Abstract

The invention provides an antifouling paint special for ships and a preparation method thereof. The method comprises the steps of mixing polysilane-modified epoxy resin, titanium dioxide and mica powder to obtain a resin mixture, and mixing the resin mixture, polytetrafluoroethylene, silicone oil, ferric oxide red and rosin to obtain the component A, and then mixing the component A with the curingagent to obtain the antifouling paint special for ships. The antifouling paint special for ships obtained by the above preparation method has the advantage of discarding the traditional organic tin antifouling agent, using the fluoropolymer and silicon polymer to form low-surface antifouling paint, and saving energy and protecting the environment under the premise of ensuring antifouling effect.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a special anti-fouling coating for ships and a preparation method thereof. Background technique [0002] Marine biofouling is ubiquitous in the marine environment and is a major problem facing the shipping industry. According to research, there are as many as 2,000 species of common marine fouling organisms, the most common being algae, hydra, barnacles, oysters, etc. Their attachment has caused great harm to ships and marine facilities, and seriously hindered the development of marine economy. Marine bio-adhesion will lead to an increase in the weight of the hull and navigational friction, and an increase in power and fuel consumption. According to statistics, the fuel consumption caused by marine fouling can increase by up to 40%, and the total cost of the voyage can increase by up to 77%. Ocean transport costs have quadrupled in the past three decades, causing...
