建筑外墙目前常用的有机、无机保温材料的使用状况和存在问题。有机保温材料具有低的导热系数,保温性能好,但是易燃、防火等级低,安全性差,需要进行阻燃处理;无机保温材料具备阻燃,防火等级高、安全性能好,但保温性能比有机保温材料差,需要开发低导热系数的无机保温材料。最后指出,综合性能优异的无机保温材料极有望可能将成为建筑保温材料的首选。 At present, the external and external walls of the building are mainly used by organic and inorganic insulation materials. Organic insulation materials with low thermal conductivity, good insulation properties, but flammable, low fire rating, poor security, the need for fire-retardant treatment; inorganic insulation materials with flame retardant, high fire rating, good safety performance, but the insulation performance than organic Insulation material is poor, the need to develop low thermal conductivity of inorganic insulation materials. Finally, pointed out that the comprehensive performance of inorganic insulation materials is very likely to become the first choice of building insulation materials.
