彩色涂层钢板，俗称彩钢板，以冷轧钢板镀上其他金属非金属或合金（锌、铝、镁、锰、硅等）为基板，经过表面处理转化后（脱脂、磷化、铬酸盐），涂覆有机涂层经烘烤制成，具有轻质高强、色彩鲜艳、耐久性好等特点。广泛应用于建筑、家电、装潢、汽车等领域。

Color coated steel plate, commonly known as color steel plate, cold rolled steel plated to other metal non metal or alloy (aluminum, zinc, magnesium, manganese, silicon etc.) as substrate, after surface treatment after transformation (degreasing, phosphating, chromate), organic coatings made by baking, has the characteristics of high strength, bright color, durability good. It is widely used in the fields of architecture, household appliances, upholstery, automobile and so on.

         

         

        彩钢板的强度取决于基板材料和厚度，耐久性取决于镀层、表面涂层和加工工艺，涂层有聚酯涂层（PE）、氟碳涂层（PVDF）、硅改性涂层（SMP）、高耐侯涂层（HDP）、丙稀酸涂层、聚氨脂涂层（PU）、塑料溶胶涂层（PVC）

Color steel plate strength depends on the substrate material and thickness, durability depends on the coating, surface coating and processing technology, coated with polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high corrosion resistance coating (HDP), acrylic acid, polyurethane coating (coating PU), plastic coatings (PVC)

等。涂层结构有二涂一烘、二涂二烘等，免维护使用年限根据环境大气不同可为10－30年。

Etc.. The coating structure has two coating, two coating and two baking. The maintenance free period can be 10-30 years according to the different environment and atmosphere.

二、常用涂料

Two. Commonly used coatings

1、聚酯(PE、Polyester )

1, polyester (PE, Polyester)

      PE涂料对于材质有良好的附着性，彩涂钢板易于加工成型，价廉且产品多，颜色和光泽的选择余地大。聚酯涂料对耐紫外光性与涂膜耐粉化性，并不理想，因此PE涂料的使用仍需受到一些限制，一般用在空气污染不严重的地区或需多次成型加工的产品。

PE coating has good adhesion to the material, color coated steel plate, easy processing, low cost and product choice, color and luster of the large. Polyester coatings are not ideal for UV resistance and film pulverization. Therefore, the use of PE coatings still needs some restrictions, which are commonly used in areas where air pollution is not serious or products that need many times to be processed.

2、硅改性聚酯（SMP,Silicone Mobified Polyester)

2, silicon modified polyester (SMP, Silicone Mobified Polyester)

      由于聚酯含有活性基-OH/-COOH，极易和其它高分子化和物反应，为改良PE的耐阳光性与粉化性，以色泽保持性与耐热性优的Silicone树脂作变性反应，和PE的变性比可于5%—50%之间，SMP提供钢板更好的持久性，其防蚀年限可长达10-12年，当然其价格也比较PE为高，但因Silicone树脂对材质的附着性和加工成型性并不理想，因此SMP彩涂钢板并不适用于需多次成型加工的场合，大部分用于建筑屋顶及外墙。

Because the polyester containing active base -OH/-COOH, easy and other polymer and reaction is improved PE resistance and pulverization of the sun, to maintain color and excellent heat resistance of Silicone resin modified reaction, and PE ratio from 5% to 50% between degeneration, persistent SMP plate well, the corrosion life of up to 10-12 years, of course, the price is relatively high in PE, but due to material adhesion and molding of Silicone resin is not ideal, so SMP color coated steel plate is not suitable for multiple processing occasions, most used for building roof and exterior wall.

3、高耐侯聚酯(HDP、High durable Polyster)

3, high tolerance polyester (HDP, High durable Polyster)

      对于PE和SMP的缺点，英国HYDRO公司（现被BASF收购）、瑞典的BECKER等在2000年初其开发出可达到PVDF涂层60-80%耐候性HDP聚酯涂料，且优于普通的硅改性聚酯涂料，其户外耐候性达到15年。高耐候聚酯树脂在合成时采用含环己烷结构的单体，来达到树脂的柔韧性、耐候性和成本的平衡，采用不含芳香族的多元醇和多元酸来减少树脂对UV光线的吸收，达到涂料的高耐候性能。涂料配方中加入紫外线吸收剂和位阻胺（HALS）提高漆膜耐候性能。高耐候聚酯卷材涂料在国外已被市场认可，该涂料性价比十分突出。

For the PE and SMP faults, British HYDRO company (now acquired by BASF), Sweden BECKER in early 2000 the developed coating can reach PVDF 60-80% HDP weatherable polyester paint, and better than the ordinary silicon modified polyester coating, its outdoorweather resistance reached 15 years. High weather resistant polyester resin with monomer containing cyclohexane structure in synthesis, to achieve the flexibility of the resin, durability and cost balance, which did not contain aromatic polyols and polybasic acid to reduce the absorption of resin for UV light, high weatherability of coatings. The UV Absorbents and HALS are added to the coating formulation to improve the weatherability of the film. High weatherproof polyester roll coating has been recognized by the market abroad, and the cost performance of this coating is very outstanding.

4、PVC 塑料溶胶（PVC Plastisol）

4, PVC plastic sol (PVC Plastisol)

      PVC树脂有很好的耐水性和耐化学药品性，一般以高固形份涂装，其涂装厚度于l00-300μm之间，能提供平滑的PVC涂膜或轻压花处理作压花涂膜;由于PVC涂膜为热可塑性树脂，具有高膜厚，能提供钢板良好的保护。但PVC耐热性较弱。在早期在欧洲使用较多，由于其环保属性相对较差，目前使用越来越少。

PVC resin has good water resistance and chemical resistance, with high solid content of coating, the coating thickness between l00-300 m, can provide a smooth PVC film or light embossing processing for embossing coating; PVC coating due for thermoplastic resin, with high film thickness, can good protection for steel plate. But the heat resistance of PVC is weak. It has been used more in Europe in the early days, because of its relatively poor environmental properties and less and less use at present.

5、PVDF

5, PVDF

      由于PVDF的化学键与化学键间，有很强的键能，因此涂料具有非常好的防蚀性和色泽保持性，在建筑工业用彩涂钢板涂料中，是属于最高级产品，且分子量大又为直键型结构，因此除耐化学药品性之外，机械性能、耐紫外线和耐热性能也很突出。在一般环境下，其防蚀年限可达20—25年之久。近年来，国内开始盛行以三氟氯乙烯和乙烯酯单体共聚的含氟树脂，大量应用于建筑的外墙和金属板，由于使用易水解的乙烯酯单体和氟的含量较PVDF低30%左右，因此其耐候性与PVDF比较，有一定的差距。宝钢所生产的氟碳涂层，其涂层PVDF含量不小于70%（其他为丙稀酸树脂）。

Due to chemical bonds and chemical bonds between PVDF, there is a strong bond energy, so the coating has good corrosion resistance and color retention, in the construction industry with painted steel coatings, is among the most advanced products, and large molecular weight and straight bond type structure, so in addition to resistance chemical resistance, mechanical properties, UV resistance and heat resistance is also very prominent. In general environment, the years of corrosion protection can reach 20 - 25 years. In recent years, the country has become popular with fluorine resin containing fluorine three vinyl chloride and vinyl monomers, is widely used in the construction of the wall and the metal plate, the 30% low hydrolysis of vinyl ester monomer and the fluorine content is about PVDF, so the weather resistance compared with PVDF, there is a certain gap. Fluorocarbon coating produced by Baosteel, the content of PVDF is not less than 70% (the other is acrylic resin).

6. Polyurethane

近年所开发的一个面漆新品种，综合性能优异，价格昂贵，正在推广中。

In recent years, a new variety of topcoat has been developed, with excellent comprehensive performance and high price, which is being popularized.
