Abstract
The utility model discloses a rust-protection composite coating for for preventing the surfaces of steel components from being rusted, which belongs to the technical field of corrosion resistance. The composite coating consisting of two types of thermosetting powder coating is tightly attached to the surface of steel component; and the bottom layer of the composite coating is rust-protection powder coating and the surface layer thereof is functional powder coating. The utility model has the advantages that the composite has excellent corrosion-resistance protection capability; the rust-protection powder coating does not contain red lead and other toxic substance and the cost thereof is lower than prior zinc-base powder coating; the surface layer of the composite coating can use ornamental powder coating or weather resistance powder coating, thereby guaranteeing the use of the product in any circumstance and achieving excellent ornamental effect and durability. The composite coating has excellent cost performance and bright application prospects.
Description
Technical field
The utility model relates to a kind of antirust compound coating that is used for anti-corrosion of metal, is specifically related to a kind of antirust compound coating of steel and iron member surface anticorrosion, belongs to the protecting metallic surface technical field.
Background technology
The method that adopts coating technology that corrosion prevention is carried out in the metallic surface is of long duration, and as all kinds of coating, metal thermal spraying coating, organic coating coating etc., has all obtained protection effect preferably.
The composite iron-titanium powder product series is the novel antirust pigment that adopts the alternative red lead powder of nanotechnology development, this rust-stabilising pigment, s-generation product WD-D type composite iron-titanium powder particularly, rust-preventing characteristic, weathering resistance all are better than red lead powder, price is lower than red lead powder, the heavy metal total content is below 2/10000ths, and it is little, of light color to have density, numerous good characteristics such as easily disperses, not stratified during use.
Summary of the invention
The purpose of this utility model provides a kind of compound coating that is used for the corrosion protection, be the antirust compound coating of steel and iron member surface anticorrosion, overcome the existing deficiency that contains red lead powder coating, rich zinc powder coating and adopt general rust-stabilising pigment powder coating to exist.This compound coating resistance to corrosion is strong, cost performance outstanding, has good decoration and protective effect.
The utility model is the problem that solves by the following technical programs:
A kind of antirust compound coating that is used for the steel and iron member surface anticorrosion, close attachment has the antirust powder coating bottom that contains the 10-40% composite iron-titanium powder on steel and iron member substrate surface surface, and bottom is outward a functional powder coating surface layer.
The antirust powder coating of described bottom does not contain red lead, and contains the 10-40% composite iron-titanium powder, and its film forming base-material is pure epoxy resin or epoxy/polyester resin, coat-thickness 40-200 μ m.
Described functional powder paint coatings is conventional decorative powder coatings coating or weather resisteant powder coating coating, coat-thickness 40-100 μ m.
The total thickness of described compound coating is 80-300 μ m, is preferably 100-150 μ m.
Its surface of protected various steel substrate can adopt existing various surface treatment method to carry out, and as modes such as bonderizing, sandblast, ball blasts, reaches cleaning surfaces, inclusion-free and has certain roughness.For further improving the anticorrosion work-ing life of member, also can carry out grinding process to the corner of member earlier before the application or carry out the metal thermal spraying processing.
The beneficial effects of the utility model are: compound coating has good corrosionproof protection ability, and antirust powder coating does not contain toxic substances such as red lead, and its cost also is lower than existing zinc-base powder coating; The decorative powder coating can be adopted in the top layer, also can adopt the weather resisteant powder coating, guarantees the use of product under various environment, has good ornamental and weather resistance.The utility model cost performance is outstanding, has a good application prospect.
