Anti-fouling coating, its preparation method, application method and application

Abstract

The application relates to the technical field of paint, and particularly discloses a scale-inhibiting paint, a preparation method and construction method and application thereof. The scale-inhibiting paint comprises components A and B; the component A comprises 1 part of polydimethylsiloxane, 0.04-0.08 parts of modified multi-walled carbon nanotubes, 0.3-0.5 parts of hydrophobic nano-silica and 8-15 parts of a solvent; the preparation method is as follows: the polydimethylsiloxane and the solvent are mixed, and then stirred and mixed at 400-600 r / min for 20-40 min; the modified multi-walled carbon nanotubes are first added and stirred and mixed for 20-40 min; the hydrophobic nano-silica is then added and stirred and mixed for 20-40 min, so as to obtain the component A; the curing agent of the component B is added into the component A, and stirred and mixed for 8-15 min, so as to obtain the scale-inhibiting paint. The scale-inhibiting paint has a high contact angle after curing, can be applied to an ultrasonic water meter, can effectively inhibit the growth of scale crystals and can improve the scale-inhibiting effect.
