Abstract
The present invention relates to a kind of urethane on rust paint with self-repair function and preparation method thereof, belong to technical field of coatings.This urethane on rust paint is made up of synthetic resins, molecular sieve, pigment, auxiliary agent, solvent, filler and solidifying agent etc.Its preparation method: first synthesize aluminium phosphate molecular sieve, then aluminium phosphate molecular sieve is through organic acid and mineral acid modification, then carries out the process of coupling agent coating, finally prepares urethane on rust paint by coating aluminium phosphate molecular sieve.This coating has controllable rusty scale conversion capability, and has good self-reparing capability to rustless steel substrate, can be widely used in the application over rust of transmission facility, bridge, boats and ships, offshore platform, port facilities, oil tank outer wall etc.
Description
Technical field
The present invention relates to a kind of urethane on rust paint with self-repair function and preparation method thereof, belong to technical field of coatings.
Background technology
Electric power facility corrodes very serious under acid rain or Coastal environments, requires that the protective coating of excellent property is protected.Electric power protective coating has certain time limit of service by Utilities Electric Co.'s regulation, as: 3 years or 5 years.Exceed the usage period when keeping in repair, often can see that some steel beam column occurs heavy corrosion because top coat destroys.These rusty scales to be removed in maintenance process, could again spray paint.For the steel angle structure of the electric tower of open air, because corner angle are very many, the restriction that power failure maintenance time is short, is difficult to the rusty scale removing steel substrate surface.If rusty scale does not thoroughly remove, will the bonding force of coating and steel substrate be affected, can cause shorten the work-ing life of coating, accelerate the corrosion of electric power steel construction.
Use on rust paint can solve the problem that this Practical Project runs into, but on rust paint performance does not also reach electric power facility requirement of shelter at present.Conventional on rust paint mainly contains osmosis type, transformant, stable form three kinds.For rust-converter coating, because coating composition is based on phosphoric acid, unnecessary phosphoric acid can affect the sticking power of finish paint, causes coating premature failure.For osmosis type, when rusty scale is more than more than 0.5mm, coating is difficult to the inside penetrating into coating.For stable form coating, when directly applying, the sticking power on rusty scale is obviously not so good as the steel substrate without rusty scale, so coating is easily peeled off.
Summary of the invention
The requirement of power system can not be met for existing on rust paint; the object of the present invention is to provide a kind of urethane on rust paint with self-repair function and preparation method thereof; the coating with self-repair function can be prepared; coating is used for corrosion metals matrix surface, the provide protection of matrix can be improved.
Technical scheme of the present invention is:
Have a urethane on rust paint for self-repair function, described urethane on rust paint is made up of following two components:
According to the mass fraction, component one comprises following component and content:
According to the mass fraction, component two comprises following component and content:
Solvent 0 ~ 50;
Solidifying agent 50 ~ 100;
Component one is (100:1) ~ (100:80) with the mass ratio of component two;
Described molecular sieve is aluminium phosphate molecular sieve, effective pore radius
