Abstract

An anticorrosion oil varnish for the surface of iron, steel and building is prepared from low-molecular epoxy resin, unsaturated polyester, tung oil, mica powder, filler and solvent through proportional mixing. Its advantages are high adhesion and anticorrosion nature, and self-cleaning function as its surficial layer can become powder layer in sun and air environmnt and then dropped down.

Description

A kind of antifouling paint

The present invention relates to chemical coating, be specifically related to a kind of antifouling paint.

Paint is used very extensive as protective system, no matter be in each class factory, to carry out industrial mechanical means, framework, the surface of crane span structure and cement works thing, or the viaduct in the city, overhead pedestrian crossing, the surface of communal facilitys such as highway barrier, generally all adopt versicolor paint as preservative coat, paint is as preservative coat, not only play preservative activity, also play the effect that mechanical means is attractive in appearance and beautify city appearance environment that makes, present widely used antifouling paint mostly is by macromolecule epoxy resin, phenylformic acid two phosphatide toughner, the organic silicone oil flow agent, titanium dioxide filler and solvent are prepared from by a certain percentage, the paint that above-mentioned each component is mixed with is brushed to by after the anticorrosion object surfaces, after solidifying, form corrosion protection coating, though this paint corrosion protection coating has played preservative effect, because its sticking power is relatively poor.Time one length will fall in flakes, so its work-ing life is shorter, is particularly polluted by dirt easily on the surface of enamelled coating, is difficult to clean, and has influenced the attractive in appearance of various device and city appearance environment.

The purpose of this invention is to provide a kind of long service life, the antifouling paint that coating itself can be self-cleaning.

In order to achieve the above object, it is as follows that the present invention prepares prescription: the antifouling paint of being made up of components such as Resins, epoxy, toughner, flow agent, mica powder, solvent, filler and pigment, its characteristics are: Resins, epoxy adopts low molecule based epoxy resin, and its content range is 25-45%; Toughner adopts not to be drunk and polyester, and its content range is 5-10%; Flow agent adopts boiled wood oil, and its content range is 5-10%; The mica powder content range is 10-30%; Solvent is toluene, dimethylbenzene or ring ethyl ketone, and its content range is 15-40%; Filler adopts titanium dioxide and talcum powder, and its content range is respectively 15-25% and 2-10%, and the content range of pigment is 0.5-2%;

The component concentration scope that has in above-mentioned each component also has preferred value, is 30-40 as the content preferable range of Resins, epoxy; The content preferable range of toughner is 2-5%; The content preferable range of flow agent is 2-5%; The content preferable range of mica powder is 15-25%; And pigment can be and can constitute versicolor pigment.

Low-molecular-weight epoxy resin among the present invention mixes with unsaturated polyester and boiled wood oil and has formed the organic substance with very strong avidity, this organic substance produces extremely strong sticking power for the inorganics surface energy, when this organic substance brushing on the inorganics surface after solidifying agent solidifies, just the jail is attached to the surface of inorganics, form preservative coat, and in mixed organism, sneak into inorganics components such as mica powder and titanium dioxide, make the preservative coat after solidifying form the sheet bisque of multilayer sudden strain of a muscle low-light, this sheet bisque, under the effect of daylight and air, can produce chemical reaction, constantly delamination efflorescence, to stick to the various dirts on its surface along with the efflorescence layer constantly comes off, thereby or when run into rain or paint efflorescence layer table that water spray also can make the efflorescence pull-up fall to appearing to make new advances and, and efflorescence layer year delamination amount is the 5-20 micron, can not influence anticorrosive quality, when having influence on anticorrosive quality after the delamination for many years, just need advance brushing antifouling paste coating again, once form corrosion protection coating and generally all can use more than 5 years.

Using method of the present invention is that the self-cleaning antifouling paste that will prepare adds solidifying agent in proportion and mixes, and slaking is after 20 minutes, evenly brushing inorganics by the rot-resistant surface on, wait to solidify after back 2 months and self-cleaning phenomenon can occur.

Since the present invention adopt by low-molecular-weight epoxy resin, unsaturated polyester refer to, formulation antifouling paste that component forms such as boiled wood oil and mica powder add solvent, make and solidify the preservative coat strong adhesion that the back forms, and the powdery delamination that preservative coat produces can come off voluntarily, appears new preservative coat and has reached self-cleaning purpose.

Describe the present invention in detail below in conjunction with embodiment, in these embodiments, all per-cents all by weight percentage.

Embodiment 1, prepare red antifouling paste

Resins, epoxy (6101), unsaturated polyester (306) red pigment, boiled wood oil, titanium dioxide, mica powder, toluene, dimethylbenzene are mixed in proportion for each 1 part, grind through sand mill, it is standby to reach fineness 40 backs, and wherein the ratio of each ingredients constitute total amount is:

Epoxy resin content is: 40%

Unsaturated polyester content is: 5%

Boiled wood oil content is: 5%

Mica powder content is: 15%

Titanium dioxide content is: 14%

Ring ethyl ketone content respectively is: 4%

Toluene, xylene content respectively are: 8%

Red inorganic pigment content is: 1%

Embodiment 2, prepare green antifouling paste

Identical with embodiment 1 compound method, just change red pigment into green color, increase the talcum powder component, adjust other component concentrations, wherein various component concentration ratios are:

Epoxy resin content is: 35%

Unsaturated polyester content is: 6%

Boiled wood oil content is: 4%

Mica powder content is: 18%

Titanium dioxide content is: 12%

Veridian content is: 1%

Ring ethyl ketone content is: 8%

Toluene, dimethylbenzene content respectively are: 8%

Below only enumerate 2 embodiment the present invention is described, also can make the self-cleaning antifouling paint of performance variation and different colours in actual fabrication process according to the pigment of the proportional range of each component and other color.
