在建筑材料领域，彩钢复合板凭借出色性能，成为各类建筑的理想之选。禹城作为该板材重要产地，产品凭借可靠质量和丰富类型，备受市场关注。下面，一起深入了解其材质构成。

In the field of building materials, color steel composite panels have become an ideal choice for various types of buildings due to their excellent performance. Yucheng, as an important production area for this board, has attracted market attention for its reliable quality and diverse types of products. Next, let's delve into its material composition together.

一、基板：坚实的根基

1、 Substrate: A solid foundation

禹城彩钢复合板基板多采用热镀锌或镀铝锌钢板。热镀锌钢板以 Q235 或 Q345 钢材为基材，镀锌量每不低于 80 克，能隔绝氧气与水分，延缓锈蚀。镀铝锌钢板表面镀覆 55% 铝、43.4% 锌与 1.6% 硅组成的合金镀层，不仅耐腐蚀性佳，耐热性也更突出。

Yucheng color steel composite board substrates often use high-quality hot-dip galvanized or aluminum zinc coated steel plates. Hot dip galvanized steel sheet is made of Q235 or Q345 steel as the substrate, with a galvanizing amount of not less than 80 grams per square meter, which can isolate oxygen and moisture and delay corrosion. The surface of aluminum zinc coated steel plate is coated with an alloy coating composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, which not only has good corrosion resistance but also outstanding heat resistance.

二、涂层：赋予外观与防护

2、 Coating: endowing appearance and protection

在基板上，禹城彩钢复合板涂有聚酯（PE）、硅改性聚酯（SMP）、氟碳（PVDF）等功能性涂层。聚酯涂层色彩丰富、加工性好，户外寿命 5 - 8 年，成本低，多用于一般工业建筑。硅改性聚酯涂层加入硅氧烷，提升了硬度与耐候性，户外寿命 8 - 15 年，适用于商业建筑。氟碳涂层以聚偏氟乙烯树脂为主，耐候、耐腐蚀且自洁性强，15 年以上不褪色，适用于高端建筑。

On the substrate, Yucheng color steel composite board is coated with functional coatings such as polyester (PE), silicon modified polyester (SMP), fluorocarbon (PVDF), etc. Polyester coating has rich colors, good processability, outdoor lifespan of 5-8 years, low cost, and is mostly used in general industrial buildings. Silicon modified polyester coating with added siloxane enhances hardness and weather resistance, with an outdoor lifespan of 8-15 years, suitable for commercial buildings. Fluorocarbon coating is mainly made of polyvinylidene fluoride resin, which is weather resistant, corrosion-resistant, and has strong self-cleaning properties. It will not fade for more than 15 years and is suitable for high-end buildings.

三、芯材：决定性能的关键

3、 Core material: the key to determining performance

1. 聚苯乙烯（EPS）芯材

1. Polystyrene (EPS) core material

EPS 芯材由可发性聚苯乙烯珠粒成型，质轻、保温佳，导热系数 0.033W/(m?K)，成本低，多用于临时建筑。但防火性能差，属 B2 级可燃材料。

EPS core material is formed from expandable polystyrene beads, which is lightweight, has good insulation, a thermal conductivity of 0.033W/(m? K), low cost, and is commonly used in temporary buildings. But it has poor fire resistance and belongs to B2 level combustible materials.

2. 挤塑聚苯乙烯（XPS）芯材

2. Extruded polystyrene (XPS) core material

XPS 芯材通过挤出工艺制成，密度更高，导热系数低 0.028W/(m?K)，抗压性强，适用于对保温和结构强度要求高的建筑，如冷库。不过较高，防火性能欠佳。

XPS core material is made through extrusion technology, with higher density and a thermal conductivity as low as 0.028W/(m? K). It has strong compressive strength and is suitable for buildings with high requirements for insulation and structural strength, such as cold storage. However, the price is high and the fire resistance is poor.

3. 聚氨酯（PU）芯材

3. Polyurethane (PU) core material

PU 芯材由异氰酸酯和多元醇发泡而成，导热系数 0.024W/(m?K)，闭孔率超 95%，防水性好。经特殊处理可达 B1 级难燃标准，广泛应用于对保温、防水和防火要求高的建筑。

PU core material is foamed with isocyanates and polyols, with a thermal conductivity of 0.024W/(m? K), a closed cell rate of over 95%, and good waterproof performance. After special treatment, it can reach the B1 level flame retardant standard and is widely used in buildings with high requirements for insulation, waterproofing, and fire prevention.

4. 岩棉和玻璃棉芯材

4. Rock wool and glass wool core materials

岩棉和玻璃棉属无机纤维材料，不燃，防火等级 A1 级。岩棉以玄武岩等为原料，玻璃棉以玻璃为原料。二者导热系数分别为 0.040W/(m?K) 和 0.038W/(m?K)，保温和吸音降噪效果好，常用于防火要求严格的建筑。

Rock wool and glass wool are inorganic fiber materials, non combustible, and have a fire rating of A1. Rock wool is made from basalt and other materials, while glass wool is made from glass. The thermal conductivity coefficients of the two are 0.040W/(m? K) and 0.038W/(m? K), respectively. They have good insulation, sound absorption and noise reduction effects, and are commonly used in buildings with strict fire protection requirements.

禹城彩钢复合板材质丰富，为不同建筑需求提供了多样解决方案。选择时，需综合考虑建筑功能、环境和预算，以发挥其优势。

Yucheng's color steel composite panels are made of a variety of materials, providing diverse solutions for different building needs. When making a choice, it is necessary to comprehensively consider the building's functionality, environment, and budget to maximize its advantages.
