Description
Technical field
The present invention relates to protective coating technical fields, and in particular to a kind of antirusting paint.
Background technique
Antirusting paint is that one kind protects metal surfaces from the chemistry of atmosphere, seawater etc. or the coating of electrochemical corrosion.?
Antirusting paint is coated in metal surface can effectively avoid the direct invasion of various corrosive substances in atmosphere, maximumlly extend
Metal service life.Conventional use of antirust paint substantially oiliness and two kinds aqueous.Oily antirust varniss makes material surface is greasy to go
Except difficulty, it has been rarely employed.Oily antirust varniss is easy to use, cheap, but because containing the Toxics such as nitrite, chromate
Matter, larger to operator's harm, country has limited use, and such properties of product are single, are not able to satisfy magnetic alloy material
Antirust requirement.
Antirusting paint currently on the market is broadly divided into physical and chemical rust coating two major classes.The former by pigment and
The appropriate cooperation of paint vehicle forms fine and close paint film to prevent the intrusion of corrosive substance, such as iron oxide red, aluminium powder, graphite antirust paint；
The latter acts on by the chemistry suppression rust of rust resisting pigment, such as red lead, zinc chromate anti-rust paint.The purposes of antirust paint is very extensive, traffic,
Building, electric power, mechanical, the every field such as ship, chemical industry have application.
