Abstract
The present invention relates to nontoxic marine antifouling paint having two components. The paint can be coated at the bottoms of ships to prevent the fouling of marine sessile organisms. In the present invention, polydimethyl siloxane and epoxy resin are used as base materials, polytetrafluoroethylene and mineral oil are used as function filling materials, titanium oxide and magnesium oxide are used as inert pigments, and polyamide is used as a curing agent. The present invention has the advantages of room temperature curing, strong adhesive force to antirust paint, strong antifouling property and no toxic and harmful effect on organisms.
Description
The present invention relates to a kind of non-toxic anti-pollution paint for sea, it has been coated on the bottom, naval vessel can prevents the stained of marine sessile organism effectively.
From the viewpoint of preserving the ecological environment, overcome toxic agent a large amount of in traditional antifouling paint (as organotin) and enter the problem of environmental pollution that cause the ocean.By reporting the low surface energy anti-fouling paint that the additive of room temperature vulcanized silicone rubber and other low surface tension is formed, its coating in use can keep very low surface tension, make marine life be difficult to adhere to reach anti-fouling effect (Mar.Eng.Rev., 1984,8,14), but have self-vulcanizing difficulty and with shortcomings such as the ground adhesion is not firm.
The object of the present invention is to provide the non-toxic anti-pollution paint for sea of a kind of pair of component, have self-vulcanizing, bond, and keep very low surface tension to prevent excellent properties such as marine sessile organism is stained with rust-inhibiting paint.
The present invention realizes by following measure:
The present invention is two component antifouling paints, is made up of base-material, functional stuffing, pigment extender, auxiliary agent, mixed solvent, solidifying agent etc.Base-material is selected polydimethylsiloxane and 6101 Resins, epoxy for use; Functional stuffing is tetrafluoroethylene, paraffin oil, and pigment extender is a zinc oxide or/and titanium oxide, and solidifying agent is a low molecular polyamides.
Non-toxic anti-pollution paint for sea of the present invention comprises (weight percentage):
A component: polydimethylsiloxane 20～29
6101 Resins, epoxy 0.6～9.0
Tetrafluoroethylene 1～9
Paraffin oil 0～3
Zinc oxide is or/and titanium oxide 1～4
Auxiliary agent 0.4～1.7
Mixed solvent 46～59
B component: polymeric amide 0.2～1.0
The mixed solvent surplus
Auxiliary agent of the present invention is made up of fluorocarbon surfactant, organo-silicon coupling agent, silicone oil, wilkinite.
Mixed solvent is made up of ketone, alcohol, ester, aromatic hydrocarbon, none provisioning request of content.
The amine value of the low molecular polyamides that the present invention selects for use is 215 ± 15, and molecular weight is 1000～1500.
Coating of the present invention is prepared by the following method:
With tetrafluoroethylene, paraffin oil, oxide compound mixed grinding, add auxiliary agent and ground solid pellet mill then earlier.Polydimethylsiloxane and Resins, epoxy are dissolved in the organic solvent with the good material of ball milling fully stir, ball milling just becomes the A component of non-toxic anti-pollution paint for sea again.
Make the B component of antifouling paint with low molecular polyamides and mixed solvent.Promptly become double-component cold curing non-toxic anti-pollution paint for sea of the present invention.Before use A, B two components are mixed, can spray or brush.
The characteristics of coating of the present invention are to adopt polydimethylsiloxane and Resins, epoxy as base-material, two components, self-vulcanizing and to marine organisms toxicological harmless effect.
Of the present invention pair of component room temperature solid non-toxic anti-pollution paint for sea is coated in the A of rust-inhibiting paint
3(150 * 300 * 300mm) rust-inhibiting paint builds are about 200 μ m on the steel plate.
The coating method of coating of the present invention is achieved in that
1, spraying: under 0.5～0.25MPa pressure, spray gun and object are maintained on the horizontal throw, coating is sprayed in the rust-inhibiting paint surface.
2, brush: coating of the present invention can be with painting brush by about the brushing direction elder generation, and the direction about the back is carried out application.
Coat-thickness of the present invention is controlled at 100 μ m～150 μ m.
Paint spay-coating of the present invention is on tinplate, and the performance characteristics of coating is as follows:
(1) drying varniss time GB1728-79,16 ℃-25 ℃ of room temperatures, 8 hours surface dryings, 36 hours actual drying time.
(2) sticking power GB1720-79 (drawing the circle method), 2 grades.
(3) snappiness GB1731-79,1mm.
(4) shock-resistance GB1732-79, just recoils by 50 kilograms centimetres.
(5) wettability, drying varniss are after 5 days, and the contact angle that records coating and distilled water with CA-A type contact angle instrument is 110-125 °.
Non-toxic anti-pollution paint for sea (percent by weight) institute coated test model according to the made double-component cold curing organo-silicone rubber of the prescription of table 1, tetrafluoroethylene is as follows with the antifouling property test of contrast model.The result is a table 2.
(1) shallow sea soak test
Applying coating of the present invention is together plunged into the commercial sea in the contrast model after 15 days in the test piece of rust-inhibiting paint, and buoyant raft is placed on free of contamination marine site, Qingdao, flow velocity＜5m/s, and each model is hung into marine with the upper, middle and lower third gear, depth of water 0.5-2m, test period 1992,4-1992,10.
(2) sticking power of antifouling coating and performance
Removal is attached to the sessile organism on the model, Ascidian, lime worm mollusk, mussel, polychaete worm, algae etc., observes paint film non-corroding, crackle are arranged, bubbles, peels off, the firm degree of adhesion of efflorescence etc. and settled organism and paint film.
