Abstract
A protecting method for prolonging the storage period of antifouling paint layer in air features that a layer of protecting film which can automatically shed off when it meets seawater is coated on the surface of antifouling paint layer. The protective film takes polyvinyl alcohol and formaldehyde as base materials and is matched with a solvent, a defoaming agent, a plasticizer and a penetrating agent. The protective film can greatly prolong the storage time of the antifouling paint on the surface of marine facilities such as ships, drilling platforms, buoys, mines and the like in the air on land, and the protective film can automatically fall off after meeting seawater, so that the antifouling paint can play a normal antifouling role.
Description
The present invention is a kind of Offshore Units and article such as drilling unit, naval vessel, buoy, navigation mark and submarine mine of being used for, and prolongs guard method and the protective material thereof of its surface soiling enamelled coating shelf-time in the air of land.
The surface of present many Offshore Units and article all scribbles antifouling varnish, to prevent halobiontic growth or to adhere to.Antifouling varnish is also varied.Yet all these antifouling varnishs but all face a problem jointly: the antifouling varnish brushing is behind product surface, and the airborne shelf-time is no more than 15 days on land, comes to this as submarine mine.In case the shelf-time is long, proof lacquer coat just takes place dry and cracked, and main is that main poison contained in the antifouling varnish expects that Red copper oxide is oxidized, has reduced the antifouling effect of antifouling varnish in seawater.
The object of the present invention is to provide guard method and the protective material thereof of a kind of staging life that prolongs proof lacquer coat in air.
Method of the present invention is achieved in that the external coating layer protecting film at proof lacquer coat, and isolated antifouling varnish contacts with air, and this protective membrane can come off after meeting seawater voluntarily.
This protective membrane (agent) is a base-material with polyvinyl alcohol and formaldehyde; auxiliary material can add solvent, defoamer, softening agent, permeate agent and make; wherein the weight percent of polyvinyl alcohol and formaldehyde is respectively 3.07-10.42; 1.22-3.06; the weight percent of solvent, defoamer, softening agent, permeate agent is respectively 55.15-122.56; 0.003-3; 0.03-0.48; 0.03-0.48 described solvent, defoamer, softening agent, permeate agent can be water, organosilicon, ammonium chloride, dioctyl maleate sodium phosphate respectively.The optimum weight per-cent of protective membrane is polyvinyl alcohol 6.13, formaldehyde 1.53, water 91.92, defoamer 0.3, softening agent 0.06, permeate agent 0.06.Also can be polyvinyl alcohol 7.2, formaldehyde 1.8, water 90.51, defoamer 0.36, softening agent 0.07, permeate agent 0.06.Perhaps, polyvinyl alcohol 6.45, formaldehyde 1.61, water 91.44, defoamer 0.32, softening agent 0.08, permeate agent 0.1.
A protectant concrete making method is: the water that adds 10kg in retort; heat 60 ℃-80 ℃ the time; the polyvinyl alcohol of 0.8kg is added in the entry, and continuously stirring is when treating that temperature rises to 90 ℃-100 ℃; control 100 minutes; polyvinyl alcohol is all dissolved, add the formaldehyde of 0.2kg then, and continuously stirring; continue 5-10 minute; after stirring evenly, add the defoamer of 0.04kg, the softening agent of 0.008kg; 0.007kg permeate agent; continuously stirring 30 minutes waits to reduce to room temperature below 35 ℃, crosses 160 purpose sieves; tested viscosity requires to be advisable second at 40-55, is preferably 45 seconds.
Be not less than 10 ℃ in temperature, humidity is not more than 85%, and under the condition that dry humidity is low 20 ℃, with external coating 2-4 time at proof lacquer coat of above-mentioned protective material goods, the preceding interval of every layer of brushing is no less than 4 hours and gets final product.
The present invention has prevented the dry and cracked and oxidation of antifouling varnish, can make the various Offshore Units and the article that scribble antifouling varnish, as naval vessel, drilling unit, navigation mark, submarine mine etc., in the air of land, be difficult for wearing out, chap, come off, shelf-time prolongs greatly, the outdoor shady and cool following shelf-time of condition extended to more than half a year, more than indoor storage time lengthening to a year.After the product that scribbles protective membrane enters seawater; in marine life growth or before beginning to adhere to (being generally about 20 days), protective membrane is just soft voluntarily through the immersion of seawater, come off, and seawater is contacted with antifouling varnish; antifouling varnish continuously discharges Cu under seawater eroding
+, normally brought into play its antifouling effect.
