Abstract
The utility model discloses a C-shaped section steel with a composite coating, belonging to the metal material and the material surface anti-corrosion field. The C-shaped section steel substrate surface is tightly attached with a protective layer composed of multiple films. The protective layer is a phosphating film layer, a zinc-based heavy-duty powder coating underlayer as well as a thermosetting powder coating spray paint plastic outer coating. With the composite coating, the utility model has the advantages of the easy and feasible construction, outstanding anti-corrosion decorative effect, excellent protection ability and good economic benefit.
Description
Technical field
The utility model relates to a kind of C shaped steel with composite coating, belongs to metal material and surface anticorrosion field thereof.
Background technology
Present steel building, has also obtained generally using as the C shaped steel of auxiliary connection and backing material obtaining to use widely aspect the construction such as large span, many high levels, steel structure of housing, portal frame, light steel house.C shaped steel generally adopts labor cleaning's steel surface, the corrosion-resistant protection processing method sprays paint at the scene after use.The producer that number of C shaped steel is produced in batches, after employing acid pickling and rust removing, table are transferred the phosphatization pre-treatment, the processing of spraying paint again.
The existing means of defence of C shaped steel can not play the effect of long-term protection steel substrate; will occur generally behind the 3-5 that rust is oozed on the surface, corrosion phenomenon such as bubble, come off; the corrosion situation is then even more serious when using out of doors, causes outstanding potential safety hazard for the building of whole lightweight steel construction.
Summary of the invention
The purpose of this utility model provides a kind of C shaped steel with composite coating, and this composite coating adopts the multiple tracks coating protection to C shaped steel, has improved the decoration protective capacities to C shaped steel, satisfies the requirement for anticorrosion of building to ferrous materials.
The utility model is the problem that solves by the following technical programs: a kind of C shaped steel with composite coating; at the topping that C shaped steel substrate surface close attachment is made up of multilayer film, topping is from inside to outside successively: phosphorization membrane, Zinc-based double antiseptic powder coating bottom, thermosetting powder coating plastic-blasting external coating.
Above-mentioned phosphorization membrane is to adopt existing phosphorization technology, and at the phosphate rete that steel substrate surface forms, composition is one-component or mutual components of mixing such as ferric phosphate, trbasic zinc phosphate, calcium phosphate, manganese phosphate.
Above-mentioned Zinc-based double antiseptic powder coating bottom is to adopt the Zinc-based double antiseptic powder coating application to form; this powdery paints is the thermosetting powder coating that contains a kind of flaky material of zinc flake at least and contain the epoxies hard resin; coating layer thickness 30-100 μ m; adopt this zinc-base coating as bottom; can give full play to its shielding protection and anodic protection effect, effectively implement protection C shaped steel base material.
Above-mentioned thermosetting powder coating plastic-blasting external coating is to be formed by the thermosetting powder coating application, used powdery paints type can be ornamental or functional thermosetting powder coating as required, comprise the pure epoxy type, the epoxy/polyester mixed type, pure polyester-type, polyurethane-type or acrylic resin type, the gloss of its coating can be that light is arranged, half light or unglazed, its coating surface can be the plane, tangerine peel, sand streak, speckle, mallear stria or spot, the appearance of coat effect also can be various metallic luster such as silver color, gold or flash of light, pearly-lustre, fluorescent effect, coating layer thickness 40-120 μ m.According to the environment for use of C shaped steel, face coat that can the choose reasonable different performance as the C shaped steel that uses, uses the epoxy/polyester mixed type indoors, and dependable performance is also saved cost; The C shaped steel of Shi Yonging out of doors, external coating can use pure polyester-type, polyurethane-type or acrylic resin type, and weather-proof effective, guard time is of a specified duration; And during to ornamental having higher requirements, then can use the powdery paints that contains the various metallic luster of various effect pigment bands, improve whole decorative effect.
The gross thickness of above-mentioned composite coating is 70-200 μ m.Cross the thin then protective capacities deficiency of coating, blocked up then cost height, usefulness waste.
The beneficial effects of the utility model are, adopt composite coating, and easy construction is easily gone, and corrosion-resistanting decoration is remarkably productive, and excellent protective capacities and good economic benefit are arranged.
Description of drawings
Accompanying drawing is the coating structure schematic diagram of rack product embodiments of the present utility model.
Among the figure: 1, C shaped steel metal base, 2, phosphorization membrane, 3, the Zinc-based double antiseptic powder coating bottom, 4, thermosetting powder coating plastic-blasting external coating.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, electrochemical deoiling is carried out on C shaped steel metal base 1 surface earlier, processing of rust removing, after table is transferred, use Zinc phosphating solution, adopt normal temperature, the impregnation method phosphatization forms phosphorization membrane 2 at steel substrate surface, after the drying, with spraying coating line on the C shaped steel, the spraying Zinc-based double antiseptic powder coating after the 160-200 ℃ of high-temperature baking gelling, forms the rich zinc bottom 3 of semi-solid preparation earlier, spray the high light powder paint of epoxy/polyester mixed type again, after solidifying 20min under 200 ℃ of high temperature, form firm composite powder coatings coating, bottom 3 is rich zinc bottom, thickness 50-70 μ m, surface layer 4 is ornamental plastic-blasting external coating, thickness 70-90 μ m, and gross thickness is 70-200 μ m.Three-layered node closes closely and with metal substrate and combines securely, reaches good decoration protection effect.
