Abstract
The present invention relates to an antifouling agent. The antifouling agent is characterized in that the antifouling agent is prepared from 20 to 60 portions by weight of calcium hydroxide with or without zinc oxide and 0.1 to 10 portions by weight of vinyl trimethoxy silane with or without 3-aminopropyl trioxethyl silane. In preparation, anhydrous alcohol and the vinyl trimethoxy silane with or without 3-aminopropyl trioxethyl silane are uniformly stirred to obtain a mixture; then the calcium hydroxide with or without zinc oxide is added in the mixture under the high-speed stirring condition; the obtained mixture is dried at 60 to 110DEGC and is ground to obtain the antifouling agent of the present invention. The antifouling agent has the advantages of strong basicity, nontoxicity, low price, favorable antifouling effect and long service life, is difficult to dissolve in water and is capable of controlling dissolving speed in water.
Description
Technical field
The present invention relates to a kind of stain control agent that contains calcium hydroxide, be used for antifouling paint, prevent that marine life from adhering on surfaces such as breed netting gear, naval vessel, coastal facility.
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.The optimal path that solves sea marine organism pollution is the coating that brushing contains stain control agent.At present, what widely apply both at home and abroad is the stain control agent that contains organotin and Red copper oxide etc., its mechanism of action is sustained release poison material, harmful dirt settling (barnacle, Ascidian, marine alga etc.) that commute is attached to hull, maritime facilities surface has lethal effect, but simultaneously, many edible marine lifes (fish, shrimp etc.) also there is tangible toxic action.In the patent No. was 97121814.5 Chinese patent, providing a kind of was the nontoxic stain control agent of major ingredient with the water glass, can dose easily in the suitable paint vehicle, obtains strong adhesion, stable performance, the nontoxic stain control agent of favorable reproducibility.This stain control agent is based on non-toxic silicate, and the latter has been the major ingredient of antifouling effect, it has been generally acknowledged that its alkalescence effect has suppressed the growth of marine life.Other composition also has zinc powder, zinc oxide, sulphur and magnesium oxide, except that forming the collaborative antifouling effect with water glass, also rises and solidifies and the solubleness regulating effect, also controls the speed that is released into of silicic acid.But the alkalescence of this stain control agent is not strong, so anti-fouling effect is also undesirable.
Summary of the invention
The purpose of this invention is to provide a kind of stain control agent and preparation method thereof, it can remedy the above-mentioned deficiency of prior art.
A kind of stain control agent, it is characterized in that containing two kinds of components, a kind of component is a calcium hydroxide, another component is a vinyltrimethoxy silane, and calcium hydroxide can be used the mixture of calcium hydroxide and zinc oxide instead, vinyltrimethoxy silane also can be used the mixture of vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene instead, and their weight range ratio is: 20-60: 0.1-10.
A kind of preparation method of above-mentioned stain control agent is characterized in that dehydrated alcohol, vinyltrimethoxy silane are stirred, and obtains mixture, calcium hydroxide is added under high-speed stirring in the said mixture again, and is dry under 60-110 ℃, grinds; Described calcium hydroxide can be used the mixture of calcium hydroxide and zinc oxide instead, and vinyltrimethoxy silane also can be used the mixture of vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene instead.
The advantage of this stain control agent is to be insoluble in water, can control water-soluble speed, and have strong basicity, and is nontoxic, cheap, good antifouling effect, long service life.
Embodiment
When preparing this stain control agent, weigh up dehydrated alcohol 100g, vinyltrimethoxy silane 4g earlier, stir, obtain mixture, weigh up calcium hydroxide 40g again, under high-speed stirring, in said mixture, add this calcium hydroxide, dry under 60-110 ℃, obtain stain control agent of the present invention through grinding.
Calcium hydroxide in the present embodiment also can be used calcium hydroxide and zinc oxide instead, and both part by weight are 1: 0.1-0.5; For example 40g calcium hydroxide is used instead 30g calcium hydroxide and 10g zinc oxide.Vinyltrimethoxy silane also can be used vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene instead, and both weight ratios are 1: 0.1-0.3; For example the 4g vinyltrimethoxy silane is used instead 3g vinyltrimethoxy silane and 1g 3-aminopropyltriethoxywerene werene.When preparing stain control agent of the present invention, the part by weight of the weight of dehydrated alcohol and calcium hydroxide or calcium hydroxide and zinc oxide sum is: 10-200: 20-60.
Claims (5)
