彩鋼夾芯板是由上下兩層彩色涂層鋼板作為面層，以既有剛度又可保溫而強度比較低的材料，如硬質(zhì)泡沫塑料、巖棉板等保濕材料作為芯材，在專用的自動化生產(chǎn)線上復(fù)合而成的，具有承載能力的結(jié)構(gòu)板材。因其構(gòu)造特征，此種板也被稱為“三明治板。”按照建筑物的使用部位和面板板型的不同，可分為屋面板、墻板、隔墻板和吊頂板等。

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.

作為一種多功能新型建筑板材，彩鋼夾芯板同時具有保溫隔熱、隔音、承載力強、色澤鮮艷、安裝靈活、造價低、防水、抗震等特點，自20世紀80年代開始已廣泛應(yīng)用于大型工業(yè)廠房、鋼結(jié)構(gòu)廠房、活動房、潔凈車間、建筑物加層、臨時房屋、倉庫、冷庫、體育館、超市以及需要保溫隔熱防火的場所。

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.

彩鋼夾芯板外形美觀，色澤艷麗，整體效果好，它集承重，保溫，防火，防水于一體，且無需二次裝修，安裝快捷方便，施工周期短，綜合效益好，是一種用途廣泛，具潛力的建材。

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.

彩鋼夾芯板的良好性能不僅僅取決于面板及面板與芯材的組合，更重要的是取決于芯材的材質(zhì)。然而，目前彩鋼夾芯板普通使用的保溫芯材或多或少都有一些弊端，大多無法同時滿足高防火保溫、耐高溫、環(huán)境友好性等特點；另一方面，該種產(chǎn)品的廠商越來越多，并且生產(chǎn)出來的產(chǎn)品大同小異，造成市場競爭十分激烈。因此，企業(yè)應(yīng)采用種新型替代保溫芯材來趕上彩鋼夾芯板領(lǐng)域不斷更新發(fā)展的強勁勢頭，提高產(chǎn)品競爭優(yōu)勢，取得更大的經(jīng)濟效益。

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.

彩鋼夾芯板保溫芯材各類及現(xiàn)狀

Types and current situation of color steel sandwich panel insulation core materials

彩鋼夾芯板的保溫、隔熱、吸聲等性能主要取決于它的芯材—絕熱材料。這種材料不僅要保溫性好，同時還需要有足夠的強度和剛度，與彩鋼板也要有很好的粘合力，只有這樣，組合的復(fù)合板才能承受設(shè)計載荷，滿足建筑功能要求。

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.

彩鋼夾芯板芯材材料按其產(chǎn)品的化學(xué)成分可分為兩大類，即一類是有機化學(xué)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。另一類是無機纖維材料，如巖棉板、礦棉板、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，國內(nèi)彩鋼夾芯板生產(chǎn)商使用的彩鋼夾芯板保溫層芯材廣泛的有聚苯乙烯夾芯板（EPS夾芯板）、硬質(zhì)聚氨脂夾芯板（PU夾芯板）、巖棉夾芯板即RW夾芯板。但聚氨脂、聚苯乙烯等有機材料耐熱溫度低、遇火易燃燒、易產(chǎn)生毒氣，成為火災(zāi)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.
