Abstract
The invention relates to waterproof anticorrosive glue, particularly to single-component polyurethane underwater sealing self-curing waterproof anticorrosive marine glue and a preparation method thereof, which mainly solve the technical problems of single effect and non-ideal effect of marine paint or marine glue at present. The marine glue of the invention is prepared by mixing diisocyanate, an anhydrous polyether mixture, a coumarone-rosin mixture and anhydrous dimethylbenzene. The mixing part proportion of the four raw materials is 1: (0.5-0.7): (0.5-0.7): (1.5-2.2), wherein the anhydrous polyether mixture as the raw material comprises the following components in percentage by weight: 15-25 percent of polyether 330, 15-25 percent of polyether 5613, 15-25 percent of polyether 403, 15-25 percent of polyether 3618 and 25-35 percent of castor oil. The coumarone-rosin mixture as the raw material comprises the following components in percentage by weight: 25-35 percent of coumarone polyester, 25-35 percent of rosin, 5-12 percent of dibutyl diformate, 1-5 percent of ultraviolet resistant anti-ageing agent, 3-7 percent of flame retardant and 20-30 percent of solvent oil. The single-component polyurethane underwater sealing self-curing waterproof anticorrosive marine glue is suitable for being exclusively used in marine ships.
Description
Technical field: the present invention relates to a kind of water-tight corrosion-proof glue, particularly a kind of single-component polyurethane underwater sealing self-curing waterproof anticorrosive marine glue and preparation method.
Background technology: ships is to be in for a long time in the ocean; seawater is more much harder than land to corrosion of metal; if do not take sfgd.; its corrosion speed is very fast; marine paint is the tailor-(made) coating on the ships, is used for protecting ship, naval vessels, offshore oil to adopt platform, harbour piling bar and marine iron structure and is not subjected to sea-water corrosion.Extra large and land natural condition are different, and there is salt fog the ocean, have subalkaline seawater and intensive ultraviolet ray etc.The hull bottom position of boats and ships is dipped in the water for a long time, suffers the galvanic corrosion of seawater.In the ocean, also have diversified marine attaching organism, adhere in their meetings alow, influence the ship speed of a ship or plane, increase fuel consumption, on national defence, more seriously influenced the fighting capacity of naval vessels, therefore require bottom paint that good water tolerance, rust-preventing characteristic are arranged; Hull bottom outermost layer coating is wanted to prevent adhering to of marine attaching organism, and is little to the human body poison during construction.And this class marine paint or marine glue at present, its effect is not satisfactory.
Summary of the invention:
The objective of the invention is to improve and a kind ofly can anticorrosion leak stopping can prevent to block the single-component polyurethane underwater sealing self-curing waterproof anticorrosive marine glue of animals and plants parasitism under water again.Mainly solve at present such marine paint or the marine glue effect is single and the unfavorable technical problem of effect.
Technical scheme of the present invention is: a kind of single-component polyurethane underwater sealing self-curing waterproof anticorrosive marine glue is mixed and is formed by vulcabond, anhydrous polyether mixture, coumarone rosin mixture, anhydrous dimethyl benzene.Four kinds of raw materials umber ratio that is mixed is: 1: (0.5-0.7): (0.5-0.7): (1.5-2.2).The weight percent that wherein anhydrous polyether mixture raw material is formed is: 15-25% polyethers 330,15-25% polyethers 5613,15-25% polyethers 403,15-25% polyethers 3618,25-35% Viscotrol C.The weight percent that coumarone rosin mixture material is formed is: 25-35% coumarone polyester, 25-35% rosin, 5-12% dibutyl carboxylic acid, 1-5% uvioresistant protective agent, 3-7% fire retardant, 20-30% solvent oil.
Compound method is: get (0.5-0.7) part anhydrous polyether mixture, (0.5-0.7) part coumarone rosin mixture, (1.5-2.2) part anhydrous dimethyl benzene and mix and stirred 15-25 minute, in whipping process, slowly add 1 part of vulcabond again, control reaction temperature is at 70-90 ℃, adding the vulcabond stirring reaction time is 1.5-2.5 hour, naturally be cooled to 25-30 ℃ and get product, finished product glue look is oil colours, and is rare as water, the as clear as crystal mediation, solids content can reach 70%.
The invention has the beneficial effects as follows: strong adhesion, solidify rapidly, the solids content height, and easily solidify automatically under water in sealing, it is tough and tensile nontoxic as stone that the back is solidified in cohesion, and transparent color and luster is bright-coloured.Its high-temperature reaction process is nature and heats up, and need not any energy heating, does not also have three waste discharge things such as any waste gas, waste water, waste residue during reaction.Over-all properties of the present invention is outstanding, has that high abrasion, height adhere to, the comprehensive function of high shock-resistant, resistance to chemical attack, and animals and plants parasitism under can exclusion of water.And alternative all kinds of high-grade lacquer, be used for decoration to various utensils surface, after this coated materials, not only its surface light is flat as mirror, and matter is hard as metal, and is suitable to the marine ship special use.
