Abstract
The utility model relates to weather-proof corrosion resistant composite color steel which is mainly aimed to solve the problem that a color steel coating is prone to generation of pulverization discoloration, cracking, peeling, dropping and the like under an adverse external environment. The weather-proof corrosion resistant composite color steel is characterized in that one layer of a polyvinylidene fluoride (PVDF) membrane is molded on the upper surface of substratum color steel by means of thermocompression, the PVDF membrane layer can block or reduce damages to the coating caused by ultraviolet rays and sulfur dioxides in rainwater and air and the like to a great extent, and the problem can be effectively solved. In addition, since the PVDF membrane can be made in multicolor such as high light or matte light, transparency or opacity, the weather-proof corrosion resistant composite color steel also has decoration effects, decorative coatings can be eliminated for some applications, and manufacturing cost of the color steel is reduced.
Description
Technical field
The utility model relates to a kind of color steel, particularly a kind of weather-proof anticorrosion compound color steel.
Background technology
Color steel is meant color coated steel sheet, promptly a kind of steel plate that has organic coating.The coating kind mainly contains polyester, acrylic resin, polyvinylidene fluoride and plastisol.Because color steel has lightweight, attractive in appearance, good anti-corrosion, machine-shaping is convenient and have advantage such as the original intensity of steel plate, is widely used in industries such as building, shipbuilding, vehicle manufacturing and electrical equipment.But, when color steel is used for building external decorative or contact adverse circumstances such as seawater for a long time, receive the effect of sulfur dioxide, salt, dust, microorganism etc., problem such as coating is easy to occur chalk masking, cracking, peeling, come off.
Summary of the invention
For overcoming above-mentioned defective, the utility model provides a kind of weather-proof anticorrosion compound colored steel, and can reach more than 25 years its service life.
Color steel upper surface has one deck PVDF film.
Between said color steel and the PVDF film adhesive phase is arranged.
The characteristic of the utility model is: the upper surface at color steel lays one deck PVDF film.Said PVDF film thickness is 0.02 to 0.2mm, can be high light or inferior light, and is transparent or opaque, also can have multiple color.
The PVDF resin mainly is meant the copolymer of vinylidene fluoride homopolymer or vinylidene and other a small amount of fluorine-containing vinyl monomers.The maximum electronegativity energy of fluorine atom makes that the fluorine carbon bond that forms is very firm, adds the unique symmetrical structure of its molecule, makes PVDF have excellent outdoor weathe resistance and corrosion resistance, fabulous antifouling property and anti-permeability performance.
So; After adopting said structure; Described PVDF film has played the certain protection effect to color steel, can intercept or reduces the destruction to coating such as ultraviolet ray, rainwater and airborne sulfur dioxide to a great extent, problem such as effectively avoid coating cracking, variable color, come off.In addition, because PVDF film itself can be made high light or inferior light, transparent or opaque and multiple color, so, have decoration function simultaneously concurrently, for some application, can save decorative coveringn, reduced the manufacturing cost of color steel.
Description of drawings
Fig. 1 is the partial schematic sectional view of a kind of weather-proof anticorrosion compound color steel of the utility model.
Among the figure: the color steel 2-of 1-adhesive phase 3-PVDF thin layer
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
A kind of weather-proof anticorrosion compound color steel of the utility model, the color steel 1 of said basic unit can produce with existing processing technology.Then, at color steel upper surface coated with polyurethane class adhesive phase 2, through the hot pressing roller PVDF thin layer 3 is forced up again.Hot pressing temperature is 150-200
oC, pressure 1-5kg/cm
2, the time is 2-5 minute.The uniformity that the strict control of whole process of production temperature, pressure and adhesive apply is combined closely to guarantee color steel and PVDF film.
Claims (3)
1. a weather-proof anticorrosion compound color steel is characterized in that at said color steel upper surface one deck PVDF film being arranged.
2. a kind of weather-proof anticorrosion compound color steel as claimed in claim 1 is characterized in that said PVDF film thickness is that 0.02mm is to 0.2mm.
3. a kind of weather-proof anticorrosion compound color steel as claimed in claim 1 is characterized in that between said color steel and the PVDF film adhesive phase being arranged.
