Abstract
The invention discloses microcapsule type self-repairing anticorrosive paint and a preparation method thereof, wherein the paint is prepared from xylene, polyurethane microcapsules, urea resin, dibutyl phthalate, polypropylene glycol, polyamide wax powder MT6650, a corrosion inhibitor, a dispersing agent and a curing agent, and the preparation method is as follows: first, uniformly stirring and mixing various components in sequence, and then adding the curing agent for curing, so as to obtain the microcapsule type self-repairing anticorrosive paint. According to the microcapsule type self-repairing anticorrosive paint and the preparation method thereof, the polyurethane microcapsules are sealed in a film, if the film is broken and damaged, the corrosion inhibitor can play a role in corrosion inhibition and protection, meanwhile, the microcapsules crack and polyurethane in the microcapsules flows out and reacts with the water in the air under the action of an assistant to form a new film to realize the self-repairing function of the film, so as to protect a substrate from being broken and corroded.
Description
Technical field
The present invention relates to anticorrosive paint technical field, be specifically related to a kind of microcapsule-type selfreparing anticorrosive paint and preparation method thereof.
Background technology
Anticorrosive paint is widely used in material protection in corrosive environment.Traditional sense is that to manufacture the anticorrosive paint of thinking be the important kind of industrial coating with " pre-antisitic defect ", occupies the biggest proportion, create huge economic benefit and social benefit in industrial coating.But coating is in use, can be affected by external environment and damaged or lose anti-corrosion function, as reparation can cause the further corrosion failure of base material not in time, be caused economic loss and danger.
In recent years, the self-repair type anticorrosive paint based on " administering damage " thinking occurred under smart coatings concept inspires causes the great interest of coating research worker, make coating when sustaining damage, automatically or accept to carry out self-healing when certain stimulates, the corrosion proof function making material is effectively recovered, thus stop spreading further of damage, extend the service life of material.Various countries scientist is carrying out extensively in-depth study to this kind of coating, and various coating raw materials implementing self-repair function are applied, it is proposed that a series of selfreparing mechanism and selfreparing model.At present, self-repair type coating obtains reality application as a new generation's anticorrosive paint, and developing this kind of coating will have the highest economic worth and prospect.
Self-healing coatings application ground zero on heavy antisepsis, research application, also in the starting stage, relates to a lot of subject, is an a kind of typical interdisciplinary difficult problem.At present, in coating, also do not add the technology of microcapsule, more can not meet the requirement of actual application, needs by the research of each subject with coordinate perfect, just can develop the satisfied coatings being actually needed.
