外墙保温材料种类很多,我们应该怎么选择呢
保温材料www.maibw.net / 2016-01-06

保温材料依据材性来分类,大体分为有机材料、无机材料和复合材料。不同的保温材料性能各异,价格也千差万别,本策划按照材料的保温性能,即导热系数的大小依次排列,并就产品的组成、材性指标、应用价值及相关厂家等进行对比。
Thermal insulation materials are classified according to the properties of materials, which can be divided into organic materials, inorganic materials and composite materials. Different insulation materials, the performance of different, prices vary widely, the planning in accordance with the material of the thermal insulation performance, namely the size of the coefficient of thermal conductivity are sequentially arranged, and product composition, material index, application value and related manufacturers, such as comparison.
1.真空绝热板
1 vacuum insulation board
导热系数傲视群雄
Thermal conductivity of Warlords
该板材由无机纤维芯材与高阻气复合薄膜通过抽真空封装技术,外覆专用界面砂浆,制成的一种高效保温板材。
The plate is composed of an inorganic fiber core material and a high resistance gas composite film through a vacuum packaging technology.
空气的导热系数大约是0.023W(m2K),真空绝热板的导热系数绝对是现有保温材料中最低的,其最大的优势,也就是其保温性能可以傲视所有其他类型的保温材料。但是,真空度难以保持,若是发生破损,真空绝热板的保温性能即会骤降;其次,现有施工工艺导致板缝太多,热桥太多,引发结露的风险很大;再者,施工平整度也较难以控制,薄抹灰系统脱落的风险也较大;当前,该产品的造价相对较高,性价比的优势不大。如果该产品造价进一步降低,倒是可以考虑应用在阳台板面防止冷桥使用。模拟成果显示,在阳台板面铺设500mm宽的真空绝热板就能起到隔绝热桥的作用,那么阳台板面就不需要大面积的铺满厚达3厘米的挤塑板了。
The thermal conductivity of air is about 0.023W (m2k). The thermal conductivity of the vacuum insulated panel is absolutely existing thermal insulation material in the lowest, its biggest advantage is its thermal insulation performance can show disdain for all other types of insulation material. But vacuum degree is difficult to maintain, if damaged, vacuum insulation panel insulation performance will sag; secondly, present construction technology lead to seam too much, too much heat bridge, causing the risk of condensation. Furthermore, construction smoothness is also more difficult to control, thin plastering system fall off and the risk is bigger also. At present, the product cost is relatively high, price of little advantage. If the product cost is further reduced, but can be applied in the balcony board to prevent the cold bridge. Simulation results show that in the balcony board laying 500mm wide vacuum insulation panels will be able to play a role in the isolated bridge, then balcony board need not large area covered with thickness of 3 cm plastic extruded board.
2.气凝胶绝热板
2 gas gel insulation board
兼备保温防火性能
Thermal insulation and fire resistance performance
气凝胶材料被称为世界上最轻的固体,气凝胶绝热板以纳米二氧化硅气凝胶为主体材料,通过特殊的工艺复合而成。
The air gel material is known as the lightest solid in the world, and the air - gel thermal insulation board is the main material with the nanometer silica gel as the main material.
气凝胶绝热板具有耐高温、导热系数低、密度小、强度高、绿色环保、防水不燃等优越性能,同时兼具优越的隔声减震性能,是冶金、化工、国防、航空航天等领域不可或缺的高效隔热保温材料。这种产品集保温性能、防火性能于一体,是很难得的材料,但是即便是在欧洲,这种材料也没有大面积的应用于建筑工程领域。一方面这种产品的造价实在太贵,另一方面,对于承受冷热循环的外保温系统主要成分,该产品还需要经受更多的考验,目前国内还没有工程案例证明其用于外墙外保温的可靠性。按照我国的国情,气凝胶材料在很长一段时间内还将是处于实验室的产品,运用于工程外保温领域似乎还不可能。
Aerogel heat insulation plate with high temperature resistance, low thermal conductivity, low density, high strength, green environmental protection, waterproof, fireproof, superior performance, while both superior sound insulation and shock absorption, is an indispensable part in the field of metallurgy, chemical industry, national defense, aerospace and other high efficient thermal insulation material. This product set insulation performance, fire performance in one, is a rare material, but even in Europe, this material does not have a large area of application in the field of construction. On the one hand, the cost of the products are too expensive, on the other hand, subjected to thermocycling insulation system main component, the products also need to endure more. Currently, there are no project case to demonstrate their use for exterior insulation reliability. In accordance with China's national conditions, the gas gel material in a long time will be in the laboratory products, the use of the project outside the insulation field seems impossible.
3.发泡聚氨酯板
3 foamed polyurethane board
最大程度防止热桥作用
The maximum extent to prevent the thermal bridge effect
发泡聚氨酯是以异氰酸酷、多元醇为主要原料加入添加剂组成双组分,经喷涂施工而成,具有绝热和防水功能。
Foaming polyurethane is a two component with different isocyanate and polyol as the main raw material, which is formed by spraying, and has the functions of heat insulation and waterproof.
聚氨酯保温材料是单一有机保温材料中性能最好的。按照工艺分为现场发泡聚氨酯和工厂预制的硬泡聚氨酯板,现场发泡聚氨酯性能更为优良。由现场发泡聚氨酯制成的绝热板材具有非常好的整体性和防水性,因此非常适合用于屋面保温和防水、地下室墙体覆土内的保温防水,以及应用于干挂幕墙内的保温。且该材料施工操作方便,可以最大程度地防止热桥作用。而硬泡聚氨酯保温板板是衍生出来的产品,由于尺寸稳定性较差,相对膨胀聚苯板并没有太大的差异。根据部分厂家提供的双面涂抹砂浆的复合聚氨酯A级板材和检测报告显示,硬发泡聚氨酯板在一段时间内可以勉强过关,作为防火保温材料使用,但新防火检验标准出台之后,该类材料将不被认可。
Polyurethane thermal insulation material is one of the best performance of organic thermal insulation materials. According to the process is divided into the field foaming polyurethane and factory prefabricated rigid polyurethane foam board, the field foamed polyurethane performance is better. Made of polyurethane foam thermal insulation plate has a very good overall and waterproof, so it is very suitable for roof insulation and waterproof, basement walls are covered in the soil of insulation and waterproof, and application to dry hanging wall heat preservation. The construction materials and convenient operation, can prevent thermal bridge effect. The hard foam polyurethane insulation board is derived from the product, due to poor dimensional stability, the relative expansion of polystyrene board is not much difference. According to the part of the manufacturers to provide double daub mortar composite polyurethane A-grade plate and test report shows that hard foaming polyurethane board within a period of time can barely pass, as fire insulation materials used, but new fire inspection standards after the introduction, this kind of material will not be recognized.
4.挤塑聚苯板
4 extruded polystyrene board
内室保温最佳选择
The best choice for inner insulation
该板材以聚苯乙烯树脂或其共聚物为成分,添加少量添加剂,通过加热挤塑成型而制得的具有闭孔结构的硬质泡沫塑料制品。
The sheet with polystyrene resin or its copolymer as an ingredient, adding a small amount of additives, manufactured by heating extrusion molding with the obturator structure of hard foam products.
挤塑聚苯板也是集防水和保温作用于一体的材料,刚度大,抗压性能好,导热系数低,用于屋面、地面、地下室墙体覆土内的内室保温是非常合适的。但是这种板材透汽性差,尺寸稳定性差,与无机粘结砂浆相比,可粘结性也较差,用于外墙体保温中常见系统脱落、饰面开裂等质量事故,由于其造价并不便宜,该材料在外保温应用领域并不及膨胀聚苯板优势大。不推荐用于外墙体保温系统中。
Extruded polystyrene board is a set of waterproof and heat preservation effect on various materials, stiffness, good compression resistance, coefficient of thermal conductivity low roof, floor, basement wall covering soil within the inner insulation is very suitable for. But this sheet through steam poor, poor dimensional stability, compared with inorganic adhesive mortar, bonding is also poor, for thermal insulation of external wall in common system off, veneer cracking quality accident, because the cost is not cheap, the material in thermal insulation applications and less expansion polyphenyl board advantage. Not recommended for exterior wall thermal insulation system.
5.酚醛保温板
5 phenolic insulation board
日式建筑偏爱酚醛板
Japanese style building
酚醛板是由苯酚和甲醛的缩聚物与其他添加剂如固化剂、发泡剂、表面活性剂和填充剂等混合制成的多孔型酚醛泡沫板。
Phenolic plate is made of phenol and formaldehyde polycondensate and other additives such as curing agent, foaming agent, surface active agent and filler made from a mixture of porous phenolic foam board.
国外生产的酚醛板具有较好的保温性能,其导热系数比挤塑聚苯板低,日本国家的夹芯保温体系大量采用酚醛板。昊瑞公司看到国内目前推广力度小,生产技术也较为落后,其保温性能略差于国外产品的市场机遇,引进国外先进的生产设备和技术经验,经过自主研发生产,形成了集研发、生产、销售、施工为一体的新型保温建材企业此外,针对国内生产的酚醛板存
Foreign production of phenolic plate has better thermal insulation performance, the coefficient of thermal conductivity is lower than that of extruded polystyrene board, Japanese national sandwich insulation system using a large number of phenolic board. Hao Rui company see domestic efforts to promote small, production technology is relatively backward, its thermal insulation performance is slightly worse than the market opportunities of foreign products, the introduction of foreign advanced production equipment and technology experience, through independent research and development production, forming a set research and development, production, sales and construction as one of the new thermal insulation building materials enterprises in addition, in view of the domestic production of phenolic board deposit
