Embodiment 1

[0026] A novel marine environment-friendly antifouling coating is prepared by the following steps:

[0027] According to the ratio of the components in Table 1, first dissolve the silicone-modified acrylic resin and the water-based acrylic-modified epoxy resin in xylene, and then add hydroxyl-terminated polydimethylsiloxane and γ-aminopropyl Triethoxysilane (KH-550), stirred at high speed and reacted for 30 minutes, then added iodopropynyl butyl carbamate, zinc oxide, talcum powder, bentonite, iron oxide, nano-silica and polytetrafluoroethylene in sequence , high-speed stirring and grinding to an average particle size of ≤ 80 μm, and high-speed stirring again after grinding to obtain a new type of marine environmental protection antifouling coating.

Embodiment 2

[0029] A novel marine environment-friendly antifouling coating is prepared by the following steps:

[0030] According to the ratio of the components in Table 1, first dissolve the silicone-modified acrylic resin and the water-based acrylic-modified epoxy resin in butyl acetate, and then add hydroxyl-terminated polydimethylsiloxane and γ-glycidol Etheroxypropyl trimethoxysilane (KH-560), stirred at high speed and reacted for 60 minutes, then added 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (SeaNine211), Zinc oxide, talcum powder, bentonite, iron oxide, nano silicon dioxide and polytetrafluoroethylene are stirred at high speed and ground to an average particle size of ≤80 μm, and then stirred at high speed again after grinding to obtain a new type of marine environmental protection antifouling coating.

Embodiment 3

[0032] A novel marine environment-friendly antifouling coating is prepared by the following steps:

[0033] According to the ratio of the components in Table 1, first dissolve the silicone-modified acrylic resin and the water-based acrylic-modified epoxy resin in xylene, and then add hydroxyl-terminated polydimethylsiloxane and γ-(methyl Acryloyloxy)propyltrimethoxysilane (KH-570), stirred at high speed and reacted for 45min, then added 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (SeaNine211 ), zinc oxide, talcum powder, bentonite, iron oxide, nano-silica and polytetrafluoroethylene, stirred at high speed and ground to an average particle size ≤ 80 μm, and then stirred at high speed again after grinding to obtain a new type of marine environmental protection antifouling coating.

Abstract

The present invention relates to a coating, in particular to a new type of marine environmental protection antifouling coating, to solve the problem that current marine antifouling coatings are harmful to marine pollution. The new type of marine environmental protection antifouling coating consists of the following components in parts by weight Composition: 10-20 parts of silicone modified acrylic resin, 10-20 parts of water-based acrylic modified epoxy resin, 5-9 parts of hydroxyl-terminated polydimethylsiloxane, 0.5-3 parts of silane coupling agent, organic 17~24 parts of solvent, 22~30 parts of environmental protection antifouling agent, 6~10 parts of zinc oxide, 2~5 parts of talcum powder, 1~3 parts of bentonite, 3~5 parts of iron oxide, 2~5 parts of nano silicon dioxide , 1~3 parts of polytetrafluoroethylene. The new marine environment-friendly antifouling paint of the present invention does not contain organic tin, cuprous oxide and other harmful substances that cause serious harm to the marine ecological environment, and avoids environmental pollution and damage. Achieve high antifouling performance.

Description

technical field [0001] The invention relates to a paint, in particular to a novel marine environment-friendly antifouling paint. Background technique [0002] The important problem encountered by ships navigating in the sea is the attachment and fouling of marine organisms to the bottom of the ship. Marine fouling organisms attaching to the bottom of the ship will increase navigation resistance, reduce ship speed, and consume more fuel; attaching to marine breeding nets will cause It will block the mesh and reduce the seawater exchange efficiency, which can lead to stunted or even death of cultured fish and shellfish; attach to marine instruments, which will cause signal distortion and performance degradation of the instruments; attach to torpedoes, increase weight and navigation resistance, and cause torpedo imbalance and failure. resulting in heavy losses. Applying antifouling coatings is an important way to solve the problem of fouling both economically and efficiently. ...
