Embodiment 1

[0034] Under a vacuum of -0.08MPa, provide 11% fluorocarbon resin, 15% tetrafluoroethylene-acryl ester polymer, 1.8% polyvinyl alcohol, 6% polyether polyester modified organosiloxane and polyamide wax 4%, each material was stirred and mixed according to the mass percentage under the condition of 1000r / min to obtain the mixture A. The mixture A was injected into the autoclave, and 26% of polysiloxane resin, 7.5% of vinyltriamine, 17% of hydroxyl acrylic resin, 13% of polyethylene glycol, polyester Type polyurethane 17%, and stir and mix under the condition of 1800. In the process of sequentially adding polysiloxane resin, curing agent, hydroxyacrylic resin, polyethylene glycol, and water-based polyurethane resin into the autoclave, sodium benzoate and polyacrylic acid were synchronously added dropwise at a speed of 12mL / min. The antifouling agent formed obtains the long-acting antifouling paint for ships of the present invention.

Embodiment 2

[0036]Under a vacuum of -0.10MPa, provide 11% fluorocarbon resin, 15% tetrafluoroethylene-acryl ester polymer, 1.8% polyvinyl alcohol, 6% polyether polyester modified organosiloxane, polyamide wax 4%, high-hardness oxide 6-8%, and chlorine-containing micropowder 3-8%, each material is stirred and mixed according to the mass percentage under the condition of 1200r / min, and the mixture B is obtained. The mixture B was injected into the autoclave, and 26% of polysiloxane resin, 7.5% of the mixture of ethylenetriamine and tetraethylenepentamine, 17% of hydroxyl acrylic resin, polyethylene 13% of diol and 17% of polycarbonate polyurethane were stirred and mixed under the condition of 2000°C. In the process of sequentially adding polysiloxane resin, curing agent, hydroxyacrylic acid resin, polyethylene glycol, and water-based polyurethane resin into the autoclave, sodium benzoate and polyacrylic acid were synchronously added dropwise at a speed of 15mL / min. The antifouling agent fo...

Embodiment 3

[0038] Under a vacuum of -0.10MPa, provide 11% fluorocarbon resin, 15% tetrafluoroethylene-acryl ester polymer, 1.8% polyvinyl alcohol, 6% polyether polyester modified organosiloxane, polyamide wax 4%, high-hardness oxide 6-8%, and chlorine-containing micropowder 3-8%, each material is stirred and mixed according to the mass percentage under the condition of 1200r / min, and the mixture C is obtained. The mixture C was injected into the autoclave, and 26% of polysiloxane resin, 7.5% of vinyl triamine, 17% of hydroxyl acrylic resin, 13% of polyethylene glycol, alkyl Alcohol amide 13%, monocrystalline silicon powder 8%, polyester polyurethane and polycarbonate polyurethane mixture 17%, and stirred and mixed under the condition of 1800°C. In the process of sequentially adding polysiloxane resin, curing agent, hydroxyacrylic resin, polyethylene glycol, and water-based polyurethane resin to the autoclave, cinnamon silicate sulfate is synchronously added dropwise at a speed of 15mL / mi...

Abstract

The invention provides long-acting antifouling paint for ships and a preparation method thereof, wherein the paint for ships is prepared from the following ingredients in percentage by mass: 12 to 25percent of fluorocarbon resin, 25 to 28 percent of organopolysiloxane resin, 12 to 20 percent of tetrafluoroethylene-propenyl ester polymers, 6.5 to 8.5 percent of curing agents, 1.6 to 2.5 percent ofpolyvinyl alcohol, 15 to 19 percent of hydroxy acrylic resin, 11 to 14 percent of polyethylene glycol, 8 to 18 percent of waterborne polyurethane resin, 24 to 28 percent of methylisobutylketone and 12 to 25 percent of auxiliary agents. The long-acting antifouling paint for the ships has the advantages that the ingredients in the paint and the ingredient content are optimized, so that the antifouling performance of a coating formed after the paint coating is improved; the ships applying the paint provided by the invention have relatively good attractive appearance and reflectivity.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a long-acting antifouling coating for ships and a preparation method thereof. Background technique [0002] Marine coatings are a general term for coatings used in various parts of ships and marine engineering structures, which can meet the requirements of preventing seawater, marine atmospheric corrosion, marine organisms adhesion and other special requirements. By coating the surface and parts of the ship with paint, the hull and its parts can be protected and their service life extended. However, although the existing marine coatings can avoid the erosion of seawater and the atmosphere, the coatings formed after coating have poor antifouling properties, which affect the overall aesthetics and reflectivity of the ship after long-term use. [0003] Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0004] The...
