Abstract
The utility model relates to a color steel plate, specifically a HDP (High Density Polyethylene) high durable polyester color steel plate; and the color steel plate mainly solves the technical problems that the color plate used for common polyester construction works can ensure the shorter using period only in the prior art and waste natural resources greatly and the like. The color steel plate provided in the utility model comprises a cold-rolled sheet (1), where the two sides of the cold-rolled sheet (1) are plated with zinc coatings (2) with anode protection effect on the cold-rolled sheet; a chemical conversion coating (3) is coated on the outer surface of each zinc coating; and a HDP high durable coating (4) is arranged on the outer surface of the chemical conversion coating.
Description
Technical field
The utility model relates to a kind of color steel, especially relates to the high durable polyester color steel of a kind of HDP.
Background technology
The color steel industry has been tending towards ripe through the domestic development of recent two decades.No matter but the kind of color steel be domestic at present or the best share of using in international market also unreasonable.The colored steel use amount that 80%-90% is arranged still is the conventional polyester colored steel.Use cost performance preferably in short period though this colored steel has, have the use of better machining property and 5-8 to protect light, colour retention ability.Also have than multiple-project and the cheap requirements on Construction of building.And,, consider the fluorine carbon color steel of durable use now mostly like high-grade engineerings such as airport, harbour, large-scale stadiums in some permanence engineerings.This color steel can satisfy guarantor's light, Bao Se and the requirement for anticorrosion of color steel in 20 years.But the fluorocarbon coating that this color steel adopted is expensive because of price comparison, adds that the working condition of this colored steel is relatively harsher, causes the colored steel integrated cost of final production to exceed a lot.On more common building engineering, be difficult to a large amount of the employing.Colored steel is used in a large amount of now conventional polyester architectural engineerings of using, and mostly can only guarantee short life cycle.Also be a kind of bigger waste simultaneously to natural resources.
The utility model content
The utility model provides the high durable polyester color steel of a kind of HDP; It mainly is to solve the architectural engineering of existing in prior technology conventional polyester to use colored steel; Mostly can only guarantee short life cycle, also be the technical problem to a kind of bigger waste of natural resources etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The high durable polyester color steel of a kind of HDP of the utility model; Comprise cold-reduced sheet; The both sides of described cold-reduced sheet are coated with the zinc coat that cold-reduced sheet is played the anodic protection effect, and the outer surface of zinc coat is coated with chemical conversion layer, and the outer surface of chemical conversion layer is provided with the high durable smart coating of HDP.The durability that color steel uses is mainly determined by color steel surface organic coating.And the primary raw material in decision coating durable service life is resin and pigment in the coating material, and some consumptions are few, but can reach the anti-ultraviolet aging agent and some other special auxiliary agent of special aging effect.The molecular weight of the high durable smart coating of HDP is preferably in 5000～7500 scopes, definitely can not use filler in its coating.HDP is high, and durable polyester color steel is compared with general color steel, and the endurable polyester color steel promptly increases 5-7 as long as can guarantee to reach the life cycle (loss of gloss eclipsed≤20%) of 10-15 the service life than common colored steel, doubles basically.
As preferably, be provided with primary coat between the high durable smart coating of described chemical conversion layer and HDP, can make the service life of coiled material in high temperature, high humidity, steam and strong corrosive environment.
As preferably, the thickness of the high durable smart coating of described HDP is 23-40 μ m.The production coating layer thickness of high durable polyester color steel all requires more than 23um (micron), in order to ensure the levelability of coating surface, to avoid mass defects such as sagging, webbing, orange peel.
Therefore, the service life that the utility model makes polyesters coating color steel, loss of gloss in 15 years was eclipsed≤20%, and cost of material price ratio conventional polyester do not have obviously big raising, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Parts, position and numbering among the figure: the high durable smart coating of cold-reduced sheet 1, zinc coat 2, chemical conversion layer 3, HDP 4, primary coat 5.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: the high durable polyester color steel of a kind of HDP of this example; Like Fig. 1; A cold-reduced sheet 1 is arranged, and the both sides of cold-reduced sheet are coated with the zinc coat 2 that cold-reduced sheet is played the anodic protection effect, and the outer surface of zinc coat is coated with chemical conversion layer 3; The outer surface of chemical conversion layer is coated with primary coat 5, and the outer surface of primary coat is coated with the high durable smart coating 4 of HDP.The thickness of the high durable smart coating of HDP is 30 μ m.
During use, this color steel can be used as interior decoration safety and uses material.
The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
Claims (3)
1. the high durable polyester color steel of a HDP; Comprise cold-reduced sheet (1); The both sides that it is characterized in that described cold-reduced sheet (1) are coated with the zinc coat (2) that cold-reduced sheet is played the anodic protection effect; The outer surface of zinc coat is coated with chemical conversion layer (3), and the outer surface of chemical conversion layer is provided with the high durable smart coating (4) of HDP.
2. the high durable polyester color steel of a kind of HDP according to claim 1 is characterized in that being provided with primary coat (5) between the high durable smart coating of described chemical conversion layer (3) and HDP (4).
