Abstract
The invention relates to an antifouling agent, which is difficult to dissolve in water with the controllable dissolving rate, and has strong alkalinity, no toxicity, low price, good antifouling effect, and long service life.
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.
Technical background
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 adheres to dried hull, maritime facilities surface has lethal effect, but simultaneously, many edible marine lifes (fish, shrimp etc.) is also had 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 main with 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 Natural manganese dioxide, except that forming collaborative antifouling work has 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 is characterized in that containing calcium hydroxide or calcium hydroxide and zinc oxide, vinyltrimethoxy silane or vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene, and their weight ratio scope is respectively: 20-60,0.1-10.
A kind of preparation method of stain control agent; It is characterized in that absolute ethyl alcohol, vinyltrimethoxy silane or vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene are stirred; Obtain mixture; Again calcium hydroxide or calcium hydroxide and zinc oxide are added under high-speed stirring in the said mixture, 60-110 ℃ dry down, obtain stain control agent of the present invention through grinding.
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 absolute ethyl 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 use 40g calcium hydroxide 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 use the 4g vinyltrimethoxy silane instead 3g vinyltrimethoxy silane and 1g3-aminopropyltriethoxywerene werene.When preparing stain control agent of the present invention, the part by weight of the weight of absolute ethyl alcohol and calcium hydroxide or calcium hydroxide and zinc oxide sum is: 10-200: 20-60.
Claims (5)
1. a stain control agent is characterized in that containing calcium hydroxide or calcium hydroxide and zinc oxide, vinyltrimethoxy silane or vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene, and their weight ratio scope is respectively: 20-60,0.1-10.
2. the preparation method of a stain control agent; It is characterized in that absolute ethyl alcohol, vinyltrimethoxy silane or vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene are stirred; Obtain mixture; Again calcium hydroxide or calcium hydroxide and zinc oxide are added under high-speed stirring in the said mixture, 60-110 ℃ dry down, obtain stain control agent of the present invention through grinding.
3. preparation method as claimed in claim 2 is characterized in that described calcium hydroxide and zinc oxide, and both weight ratios are 1: 0.1-0.5.
4. preparation method as claimed in claim 2 is characterized in that described vinyltrimethoxy silane and 3-aminopropyltriethoxywerene werene, and both weight ratios are 1: 0.1-0.3.
