Abstract
The present invention relates to an antifouling agent for paint. The antifouling agent is characterized in that the antifouling agent is prepared from cuprous oxide and vinyltrimethoxysilane or vinyltrimethoxysilane at a weight ratio of 20 to 80:0.1 to 10. Anhydrous alcohol and the vinyltrimethoxysilane or the vinyltrimethoxysilane is uniformly stirred to obtain a mixture; then cuprous oxide is added to the mixture under the stirring condition, and the obtained mixture is dried at 60 to 110 DEG C under the nitrogen protection after the ethanol is centrifugally removed; the weight ratio of the anhydrous alcohol to the cuprous oxide is 10 to 200:20 to 60. The antifouling agent has the advantages of high lipophilicity, high compatibility in a paint, easy control of release speed, quantity reduction in paint, cuprous oxide saving and cost reduction of paint.
Description
Technical field
The present invention relates to a kind of stain control agent, particularly relate to a kind of coating stain control agent and preparation method thereof.
Background technology
The device surface that immerses netting gear in the seawater, hull, buoy, bridge pier, harbour and other and contact with sea water is usually owing to adhere to marine life, and causes surperficial stainedly, increases surperficial frictional resistance, also quickened corrosion.At present, the optimal path of solution sea marine organism pollution is the coating that brushing contains stain control agent.Widely apply the multipolymer and the Red copper oxide (Cu of methacrylic acid tributyl tin ester and methyl methacrylate both at home and abroad
2O) composition is coated on surfaces such as hull bottom as a kind of antifouling paint, can prevent the harm of marine fouling organism effectively.Multipolymer in this antifouling paint is the meeting hydrolysis in seawater, discharges tributyl tin (TBT), brings into play antifouling effect.But the TBT harm marine eco-environment and sea farming industry cause gender variation and the housing distortion of oyster, blood clam and mussel as TBT.Therefore, noted developing the antifouling paint that does not contain organotin both at home and abroad, but a large amount of Red copper oxide that use are as stain control agent in these coating, the usage quantity of Red copper oxide has accounted for 30～60% of coating nonvolatile component.Because Red copper oxide has than the characteristic great, that wetting ability is strong, make these coating be easy to generate sedimentation and Red copper oxide easily is discharged in the water body, cause the use difficulty of antifouling paint and the efficient low shortcoming of Red copper oxide.
Summary of the invention
The purpose of this invention is to provide a kind of coating stain control agent and preparation method thereof, it can remedy the above-mentioned deficiency of prior art.
A kind of coating stain control agent is characterized in that containing Red copper oxide, vinyltrimethoxy silane or vinyltriethoxysilane, and their weight ratio scope is: 20-80: 0.1-10.
The preparation method of above-mentioned coating stain control agent; it is characterized in that dehydrated alcohol and vinyltrimethoxy silane or vinyltriethoxysilane are stirred; obtain mixture; again Red copper oxide is under agitation added in the said mixture, through centrifugal slough ethanol after under nitrogen protection in 60-110 ℃ of drying.
The advantage of this stain control agent is that lipophilicity is good, and good compatibility is arranged again in coating, and release rate easy to control can be reduced in the usage quantity in the coating, saves Red copper oxide, reduces the coating cost.
Embodiment
When preparing this stain control agent; weigh up dehydrated alcohol 100g, vinyltrimethoxy silane 4g earlier; stir; obtain mixture; weigh up Red copper oxide 40g again; add this Red copper oxide under high-speed stirring in said mixture, centrifugal sloughing behind the ethanol under nitrogen protection in 60-110 ℃ of drying obtains stain control agent of the present invention through grinding.
Vinyltrimethoxy silane also can be used vinyltriethoxysilane instead in the present embodiment, for example uses the 4g vinyltrimethoxy silane instead the 4g vinyltriethoxysilane.When preparing stain control agent of the present invention, the weight of used dehydrated alcohol and the part by weight of Red copper oxide are: 10-200: 20-60.
Claims (3)
1 one kinds of coating stain control agents is characterized in that containing Red copper oxide, vinyltrimethoxy silane or vinyltriethoxysilane, and their weight ratio scope is: 20-80: 0.1-10.
The preparation method of the described coating stain control agent of 2 claims 1; it is characterized in that dehydrated alcohol and vinyltrimethoxy silane or vinyltriethoxysilane are stirred; obtain mixture; again Red copper oxide is under agitation added in the said mixture, through centrifugal slough ethanol after under nitrogen protection in 60-110 ℃ of drying.
3 preparation methods as claimed in claim 2 is characterized in that the weight of described dehydrated alcohol and the part by weight of Red copper oxide are: 10-200: 20-60.
