Description

Self-cleaning color steel plate

Technical Field

The utility model relates to a civil construction panel field, concretely relates to steel sheet is scribbled to automatically cleaning color.

Background

The color coated steel plate is a steel plate with an organic coating, has the advantages of light weight, high strength, bright color, flexible and quick installation and the like, and is widely applied to the wall surfaces and the roof surfaces of large-scale public buildings, public plants, movable board houses and integrated houses. However, as the paint is used for a long time, more dust is adsorbed on the surface of the paint, the attractiveness of a building is seriously influenced, the paint is difficult to clean because the formed building is a large building, and the organic coating on the surface of the color-coated steel plate is damaged at an accelerated speed due to the long-time adhesion of the dust on the surface, so that the internal steel plate is easy to rust, and the service life of the building is shortened.

Therefore, the color-coated steel plate adopted by part of large buildings is a self-cleaning color-coated plate. The self-cleaning color-coated sheet has hydrophilicity, oily pollutants in the air are not easy to adhere to the hydrophilic coating surface, and the rainwater has good wettability on the hydrophilic coating surface and can be easily spread into a water film, so that the pollutants can be easily taken away, and rain marks can not be left.

The existing self-cleaning color-coated steel plate in the market has the following two problems:

1. the steel plate is delivered from a factory in a whole roll mode, is cut on site according to the size of a building during construction, occupies a large field, and needs to be provided with a series of cutting tool fixtures and auxiliary tools;

2. the self-cleaning plates in the market are all provided with two coating organic coatings, the priming paint and the finishing paint are added (the self-cleaning effect is achieved by adding the hydrophilic auxiliary agent), the self-cleaning effect is short in time effect and poor in effect, and after the self-cleaning plates are manufactured, the hydrophilic self-cleaning effect can be embodied only by curing for a certain time.

Disclosure of Invention

To the technical problem, the utility model discloses a colored steel sheet of automatically cleaning, this steel sheet adopt modularization mosaic structure, and transportation, construction convenience are swift, and the hydrophilic angle of three coating structures is lower, long service life, clean effect are showing.

A self-cleaning color steel plate comprises a plurality of adjacent splicing units, wherein longitudinal connecting holes and transverse connecting holes which are perpendicular to each other are formed in four corner points of each splicing unit, the adjacent splicing units are connected through splicing blocks, reinforcing holes are formed between two corner points of each splicing unit, reinforcing shafts are arranged in the reinforcing holes in a matched mode, the reinforcing shafts penetrate through one part of the splicing blocks, and the axes of the connecting holes and the reinforcing holes are parallel to the largest surface of each splicing unit; each splicing unit comprises a steel plate substrate, the outer surface of the steel plate substrate is sprayed with an anti-corrosion primer coating, the surface of the anti-corrosion primer coating is sprayed with a toning finishing paint layer, and the surface of the toning finishing paint layer is sprayed with a self-cleaning inorganic coating.

Preferably, four corner points of the splicing unit are all provided with angular notches.

Preferably, the inserting block comprises an end part and inserting legs, the end part is used for filling the corner notches of the splicing units, and the inserting legs are communicated with the connecting holes.

Preferably, the reinforcing shaft is connected with the side surface of the splicing unit through a screw.

Preferably, the coating thickness of the anti-corrosion primer is 4-6 microns.

Preferably, the thickness of the toning finishing coat layer is 14-16 microns.

Preferably, the self-cleaning inorganic coating has a thickness of 0.5 to 2 microns.

The utility model has the advantages that:

the utility model discloses a three coating high clean board, priming paint add the finish paint and add professional automatically cleaning inorganic coating, compare with the conventional 2 coating auxiliaries automatically cleaning modes in the past, have following peculiar point:

1. the self-cleaning effect is more obvious, the hydrophilic effect is stronger, the hydrophilic angle is lower, the hydrophilic angle of the market conventional product cannot be lower than 30 degrees, while the hydrophilic angle of the three-coating high-cleaning plate developed by the people is lower than 20 degrees;

2. the self-cleaning effect is longer. Market 2 coating aid type self-cleaning products, after 4 years of outdoor hydrophilicity, decline dramatically. The three-coating high-cleanness plate has the advantages that the hydrophilicity is always present as long as the inorganic coating exists, the outdoor maintenance time is longer than 10 years, and the hydrophilic aging is 2-3 times that of the common self-cleaning color plate in the market;

3. market 2 coating assistant formula self-cleaning product, after the colored sheet was accomplished, surface coating need utilize humidity, rainwater, dew curing period in the open air, just can have hydrophilic effect, and the curing period depends on factors such as outdoor temperature, humidity. The three-coating high-cleanness plate does not need a curing period, can immediately embody hydrophilicity after the color plate is finished, and does not influence the color vividness of the color-coated steel plate.

4. The splicing mode is convenient for transportation and construction, and the application of the splicing block and the reinforcing shaft ensures that the assembly and disassembly are convenient and reliable.
