彩钢夹芯板是由上下两层彩色涂层钢板作为面层，以既有刚度又可保温而强度比较低的材料，如硬质泡沫塑料、岩棉板等保湿材料作为芯材，在专用的自动化生产线上复合而成的，具有承载能力的结构板材。因其构造特征，此种板也被称为“三明治板。”按照建筑物的使用部位和面板板型的不同，可分为屋面板、墙板、隔墙板和吊顶板等。
The color steel sandwich board is a structural board with load-bearing capacity, which is composed of two layers of color coated steel plates as the surface layer, and low-strength materials with both rigidity and heat preservation, such as hard foam plastic, rock wool board and other moisturizing materials as the core material, on a special automatic production line. Because of its structural characteristics, this kind of plate is also called "sandwich plate" According to the use position and panel type of the building, it can be divided into roof panel, wall panel, partition board and ceiling board.
作为一种多功能新型建筑板材，彩钢夹芯板同时具有保温隔热、隔音、承载力强、色泽鲜艳、安装灵活、造价低、防水、抗震等特点，自20世纪80年代开始已广泛应用于大型工业厂房、钢结构厂房、活动房、洁净车间、建筑物加层、临时房屋、仓库、冷库、体育馆、超市以及需要保温隔热防火的场所。
As a new multi-functional building board, the color steel sandwich board has the characteristics of thermal insulation, sound insulation, strong bearing capacity, bright color, flexible installation, low cost, waterproof and anti-seismic. Since the 1980s, it has been widely used in large industrial plants, steel structure plants, activity rooms, clean workshops, building storey addition, temporary houses, warehouses, cold storages, gymnasiums, supermarkets and places requiring thermal insulation and fire prevention.
彩钢夹芯板外形美观，色泽艳丽，整体效果好，它集承重，保温，防火，防水于一体，且无需二次装修，安装快捷方便，施工周期短，综合效益好，是一种用途广泛，具潜力的建材。
The color steel sandwich panel has beautiful appearance, bright color and good overall effect. It integrates load-bearing, thermal insulation, fire prevention and waterproof, and does not need secondary decoration. It is fast and convenient to install, short construction cycle and good comprehensive benefits. It is a building material with wide uses and potential.
彩钢夹芯板的良好性能不仅仅取决于面板及面板与芯材的组合，更重要的是取决于芯材的材质。然而，目前彩钢夹芯板普通使用的保温芯材或多或少都有一些弊端，大多无法同时满足高防火保温、耐高温、环境友好性等特点；另一方面，该种产品的厂商越来越多，并且生产出来的产品大同小异，造成市场竞争十分激烈。因此，企业应采用种新型替代保温芯材来赶上彩钢夹芯板领域不断更新发展的强劲势头，提高产品竞争优势，取得更大的经济效益。
The good performance of color steel sandwich panel depends not only on the panel and the combination of panel and core material, but also on the material of core material. However, at present, the thermal insulation core materials commonly used in color steel sandwich panels have more or less some disadvantages, most of which can not meet the characteristics of high fire insulation, high temperature resistance and environmental friendliness at the same time; On the other hand, there are more and more manufacturers of this kind of products, and the products produced are similar, resulting in fierce market competition. Therefore, enterprises should adopt a new type of alternative insulation core material to catch up with the strong momentum of the continuous renewal and development of the field of color steel sandwich panels, improve the competitive advantage of products and achieve greater economic benefits.
彩钢夹芯板保温芯材各类及现状
Types and current situation of color steel sandwich panel insulation core materials
彩钢夹芯板的保温、隔热、吸声等性能主要取决于它的芯材—绝热材料。这种材料不仅要保温性好，同时还需要有足够的强度和刚度，与彩钢板也要有很好的粘合力，只有这样，组合的复合板才能承受设计载荷，满足建筑功能要求。
The thermal insulation, heat insulation and sound absorption properties of color steel sandwich panel mainly depend on its core material - thermal insulation material. This kind of material should not only have good thermal insulation, but also have sufficient strength and stiffness, and have good adhesion with color steel plate. Only in this way can the combined composite plate bear the design load and meet the functional requirements of the building.
彩钢夹芯板芯材材料按其产品的化学成分可分为两大类，即一类是有机化学泡沫材料，如聚氨脂泡沫塑料、聚苯乙烯泡沫塑料、酚醛泡沫塑料、三聚氨泡沫塑料等。另一类是无机纤维材料，如岩棉板、矿棉板、玻璃棉板等。
The core materials of color steel sandwich panels can be divided into two categories according to the chemical composition of their products, that is, one is organic chemical foam materials, such as polyurethane foam, polystyrene foam, phenolic foam, melamine foam, etc. The other is inorganic fiber materials, such as rock wool board, mineral wool board, glass wool board, etc.
目前，国内彩钢夹芯板生产商使用的彩钢夹芯板保温层芯材广泛的有聚苯乙烯夹芯板（EPS夹芯板）、硬质聚氨脂夹芯板（PU夹芯板）、岩棉夹芯板即RW夹芯板。但聚氨脂、聚苯乙烯等有机材料耐热温度低、遇火易燃烧、易产生毒气，成为火灾事故的主要因素之一。
At present, domestic color steel sandwich panel manufacturers use a wide range of color steel sandwich panel insulation layer core materials, including polystyrene sandwich panel (EPS sandwich panel), hard polyurethane sandwich panel (PU sandwich panel) and rock wool sandwich panel, namely RW sandwich panel. However, organic materials such as polyurethane and polystyrene have low heat-resistant temperature, easy to burn in case of fire and easy to produce toxic gas, which have become one of the main factors of fire accidents.
