保温砂浆是以各种轻质材料为骨料,以水泥为胶凝料,掺和一些改性添加剂,经生产企业搅拌混合而制成的一种预拌干粉砂浆。主要用于建筑外墙保温,具有 施工方便、耐久性好等优点。目前市面上的保温砂浆主要为两种:无机玻化微珠保温砂浆;胶粉聚苯颗粒保温砂浆。而‘EVB保温砂浆’、‘微晶保温砂浆’等属于无机玻化微珠保温砂浆,只是无机保温砂浆的一个别称。

Thermal insulation mortar is based on a variety of lightweight materials as aggregates, cement as the cementing material, with some modified additives, made by the production enterprise and mixing a ready-mixed mortar powder. Mainly used for building exterior wall thermal insulation, has the advantages of convenient construction, good durability. Thermal insulation mortar currently on the market are mainly two kinds: inorganic vitrified beads insulation mortar; Powder polystyrene particles insulation mortar. And 'EVB insulation mortar' and 'microcrystalline insulation mortar belongs to inorganic vitrified beads insulation mortar, is just a nickname of inorganic insulation mortar.


前者是由优质海泡石绒,硅酸铝纤维、膨胀珍珠岩、有机硅等各种优质绝热材料及高分子聚合物复合而成,具有优良的保温性能广泛用于墙体、罐体、冷库、管道等保温。后者是一种新型保温材料,由胶粉和聚苯颗粒两种成分。施工工艺由保温层、抗裂防护层和防水饰面层组成,保温层采用胶粉聚苯颗粒保温砂浆,抗裂防护层,是在抗裂砂浆中加入涂塑抗碱玻纤网格布,防水层是将弹性底漆涂在防护层表面,饰面为涂料和面砖。

The former is composed of high quality sepiolite velvet, aluminum silicate fiber, expanded perlite, organic silicon, etc all kinds of high quality thermal insulation material and polymer compound, with excellent insulation properties are widely used in wall body, tanks, cold storage, such as pipe insulation. The latter is a kind of new thermal insulation material by powder and polystyrene particles of two components. Construction technology by insulation, anti-crack and waterproof surface protective layer of insulation layer using powder polystyrene particles insulation mortar, anti-crack protective layer, is to join in the anti-crack mortar plastic coated alkali resistant glass fiber grid cloth, the waterproof layer is the elastic primer on the surface protective layer, facing for coating and face brick.


保温砂浆材料主要特点有:采用柔软性抗裂技术。各层材料弹性模量变化指标相匹配逐层渐变,允许变形与限制变形相结合,能够随时分散和消解变形应力。基层变 形适应性强,有效地防止墙面裂缝的产生;体系无空腔,抗负风压能力强,适用于多层及高层建筑;透气性好,呼吸功能强,既有很好的防水功能,又能排解保温层的水分;具有极好的耐候性能。导热系数低、保温性能稳定、软化系数高,耐冻融、抗老化;保温砂浆材料综合造价较低。

Main features are: thermal insulation mortar materials adopt flexible crack technology. Each layer material elastic modulus variation index matching step by step a gradient, deformation and limits allowed to combine, can scatter and deformation stress. Grass-roots form strong adaptability, effectively prevent the cracks of wall; No cavity system, negative wind pressure resistance is strong, suitable for multi-storey and high-rise buildings; Good ventilation, respiratory function is strong, has very good waterproof function, and can deal with thermal insulation layer of moisture. Has excellent weather resistance. Low thermal conductivity, thermal insulation performance stability, softening coefficient, high resistance to freezing and thawing, anti-aging; Thermal insulation mortar materials comprehensive cost is low.
