Abstract
An anti-polluting paint with low surface energy for sea is prepared from modified organosilicon, chlorowax, aid, solidifying agent and mixed solvent, and features solidification at ordinary temp, better adhesion to antirust paint, low surface energy, and no pollution and damage to sea living things.
Description
The present invention relates to a kind of low surface energy antifouling coating for seas, it is coated on bottom of ship can prevents the stained of marine sessile organism.
The wherein contained toxic agent of traditional antifouling paint utilization oozes out and fouling organism is caused death with certain speed, but a large amount of toxic agent enters the ocean, has polluted ecotope.Therefore, develop the non-toxic long-acting antifouling paint and become the important topic of being badly in need of solution in the world.Antifouling paint so that modified room-temperature-cured silicone rubber and other low surface tension additive are formed makes marine organisms be difficult to adhere to the effect that reaches antifouling.(CN1097447A, non-toxic anti-pollution paint for sea, Tian Jun, Zhou Zhaofu, Xu Jinfen).
The object of the present invention is to provide a kind of low surface energy anti-fouling paint, it has self-vulcanizing, bonds with ground, prevents the excellent properties of marine biofouling again.
Purpose of the present invention realizes by following measure:
The present invention is two components, is formed by modulation such as base-material, clorafin, auxiliary agent, solidifying agent and mixed solvents.Base-material is selected modified organic silicone resin for use, the low surface energy additive is a clorafin, auxiliary agent is a zinc oxide etc., solidifying agent is a low molecular polyamides, the present invention fills a prescription and mainly comprises (weight percentage) A component: modified organic silicon 22-35%, clorafin 5-18%, zinc oxide 1-5%, other auxiliary agent 0.5-1%, organic solvent 46-55%.B component: polymeric amide 0.2-1%, organic solvent surplus.
Auxiliary agent of the present invention is by silicone oil, compositions such as fluorocarbon surfactant.
The amine value of the low molecular polyamides that the present invention selects for use is 215 ± 15, and molecular weight is 1000-1500.
Organic solvent of the present invention is aromatic hydrocarbon, ketone.
The preparation method of modified organic silicon of the present invention comprises:
A) 8-20% Resins, epoxy (oxirane value 0.41-0.47, hydroxyl value 0.06, molecular-weight average 300-400) is put into the four-hole boiling flask of being furnished with electric mixer, heat temperature raising to 110 ℃ drips catalyzer (dibutyl tin dilaurate of 0.1-0.5%).
B) progressively adding 78-90% carried out condensation reaction in 5 hours with the insulation of hydroxy-end capped polydimethylsiloxane and makes.
The concrete preparation process of coating of the present invention is: with clorafin, zinc oxide mixed grinding, add silicone oil, fluorocarbon surfactant and ground solid pellet mill then.Modified organic silicon is dissolved in the organic solvent with the good material of ball milling fully stirs, ball milling just becomes the A component of low surface energy 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 low surface energy non-toxic anti-pollution paint for sea of the present invention.Before use A, B two components are mixed, can spray or brush.
Characteristics of the present invention adopt the modified organic silicon base-material, two components, low surface energy, self-vulcanizing and to marine organisms toxicological harmless effect.
Double-component cold curing low surface energy non-toxic anti-pollution paint for sea of the present invention.Be coated in that (150 * 300 * 1mm), the rust-inhibiting paint build is about 200 μ m on the A3 steel plate of rust-inhibiting paint.
Coating method of the present invention is achieved in that
1, spraying: under 0.25-0.5MPa 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 carry out application by the first direction about the back up and down of brushing direction with painting brush.
Coat-thickness of the present invention is controlled at 100 μ m-150 μ m, can obtain promising result.
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 dryings.
2) sticking power GB1720-79 (drawing the circle method), 2 grades.
3) snappiness GB1731-79,1mm.
4) hardness (pencil method), 2B.
5) surface energy of coating: 106.5 ° of the contact angles of coating and glycerine, the contact angle of coating and distilled water are 114.5 °.Coatingsurface can calculate: 9.68mNm
-1
6) solvability (30 days, 20 ℃) in the water: weightlessness 4.8% in the distilled water; (salinity 3.5%) weightless 6.7% in the artificial seawater.
According to the modified organic silicon of the made double-component cold curing of the prescription of table 1, low surface energy non-toxic anti-pollution paint for sea (percentage composition) the institute coated test model of clorafin is as follows with the antifouling property test of contrast model, and the result is a table 2.
1, after the antifouling coating preparation, the entry phase is no more than 20 days.
2, the shallow sea soak test is in Xiamen sea area, and sample is apart from about the water surface 0.4-1.5 rice.Water speed 0.5 meter per second, the waters is pollution-free.
3, soak time: in August, 1994-1996 year April.
