Abstract
The invention provides self-repairing anticorrosive paint which can realize self-repairing and protect a bottom material from being corroded and a preparation method thereof. The self-repairing anticorrosive paint disclosed by the invention comprises hydroxyl-contained acrylic resin, pigment, corrosion-inhibiting pigment, benzotriazole as a corrosion inhibitor, a polyurethane microcapsule, an organic solvent, a dispersant, a defoaming agent, a leveling agent and an ultraviolet absorber. In the self-repairing anticorrosive paint and the preparation method of the self-repairing anticorrosive paint, when a paint film is broken and damaged, the benzotriazole as the corrosion inhibitor can perform the action of corrosion-inhibiting protection, and meanwhile, the microcapsule is broken, polyurethane in the capsule flows out and reacts with water in air under the action of the corrosion-inhibiting pigment as an auxiliary agent to form a new paint film, so that the self-repairing function of the paint film is realized, and the bottom material is further protected from being destroyed and corroded.
Description
Technical field
The present invention relates to a kind of coating and preparation method thereof, especially a kind of selfreparing protective system and preparation method thereof.
Background technology
In 21 century, the application ground zero of selfreparing coating on weight is anticorrosion, Application Research relates to a lot of subjects also in the starting stage, is an a kind of typical interdisciplinary difficult problem.At present, also in coating, do not add the technology of microcapsule, more can not satisfy requirement of actual application, need through each subject research with cooperate perfectly, just can develop the selfreparing coating that satisfies actual needs.
Summary of the invention
The invention provides and a kind ofly can realize self-regeneration, selfreparing protective system that the protection ground is not corroded and preparation method thereof.
Realize the selfreparing protective system of one of the object of the invention, comprise, contain hydroxy propylene acid resin, pigment, corrosion inhibiting paint, corrosion inhibitor-benzotriazole, polyurethane microcapsule, organic solvent, dispersion agent part, skimmer, flow agent, ultraviolet absorbers.
Wherein, contain hydroxy propylene acid resin 50～60wt%, pigment 15～20wt%; Corrosion inhibiting paint 3～7wt%, corrosion inhibitor benzotriazole 2～5wt%, polyurethane microcapsule 3～8wt%; Organic solvent 12～20wt%, dispersion agent 0.2～0.4wt%, skimmer 0.2～0.4wt%; Flow agent 0.3～0.4wt%, ultraviolet absorbers 1～3wt%.
Described organic solvent is YLENE or butyl ester.
Described selfreparing protective system also comprises anti-settling agent and photostabilizer.
Said anti-settling agent 0.5～1.0wt%, photostabilizer 0.2～0.4wt%.
Realize the preparation method of two the selfreparing protective system of the object of the invention, comprise the steps:
(1) adding contains hydroxy propylene acid resin and dispersion agent in the condiment still, under agitation adds pigment, corrosion inhibiting paint and organic solvent, after high speed dispersion is even, is ground to fineness less than 20um;
(2) under stirring at low speed, add benzotriazole, polyurethane microcapsule, skimmer, flow agent again, ultraviolet absorbers, photostabilizer and anti-settling agent are uniformly dispersed;
(3) adjust viscosity with organic solvent, sampling adds solidifying agent and solidifies.
Solidifying agent in the said step (3) comprises that isocyanic ester HDI tripolymer is made 50～70wt%, ethyl ester 5-10wt%, YLENE 20-40wt% dewater.
When said step (3) is solidified, allocate with 5: 1 ratios of solidifying agent in main lacquer.
The beneficial effect of selfreparing protective system of the present invention and preparation method thereof is following:
Selfreparing protective system of the present invention and preparation method thereof adopts urethane to be wrapped in and processes polyurethane microcapsule in the microcapsule, in acroleic acid polyurethane finish paint prescription; Add the benzotriazole corrosion inhibitor, adopt the polyurethane microcapsule of appropriate particle size, make curing of coating, be enclosed in polyurethane microcapsule and film through adding solidifying agent; When breaking damage if film; The benzotriazole corrosion inhibitor can play the inhibition protection effect, and simultaneously microcapsule break, the urethane outflow in the capsule, under the effect of auxiliary agent corrosion inhibiting paint; React with airborne water; Form new filming, the self-regeneration function that realizes filming, and then the protection ground is not destroyed and corrodes.
