硅酸盐保温砂浆被广泛应用到建筑保温中

复合硅酸盐保温涂料是当前应用最广泛的保温涂料。这类保温涂料最初以松解过的海泡石作为主要原料,以水玻璃为主要黏结剂。后来除海泡石外,还加入大量的膨胀珍珠岩、膨胀蛭石、漂珠、粉煤灰、硅藻土、石棉、玻璃棉、矿棉、硅酸铝纤维等;所用黏结剂也由单一的水玻璃发展为石膏(常温)、水泥(常温)、高铝水泥(中温)、硅溶胶(高温)等复合使用。此外,还通过加入各种外加剂来改善涂料性能,如流动性、硬化性、憎水性、耐高温性、反射性等。经过机械打浆、发泡、搅拌等工艺制成膏状保温涂料。

 composite silicate insulation coating is currently the most widely used thermal insulation coatings. This kind of heat preservation coating initially in order to release the sepiolite as the main raw material, sodium silicate as the main adhesives. Later, in addition to sepiolite, also add a lot of expanded perlite, expanded vermiculite, floating bead, fly ash, diatomite, asbestos, glass wool, mineral wool, aluminum silicate fiber, etc.; Adhesives are used by a single development for gypsum (room temperature), sodium silicate cement (room temperature), high alumina cement (temperature) and compound use silicon sol (high temperature). In addition, by adding various additives to improve the coating performance, such as liquidity, sclerosing, hydrophobic, high temperature resistance, reflective, etc. After beating machine, foam, mixing technology were made into paste insulation coating.

目前无机保温砂浆较成熟的技术主要是膨胀玻化微珠保温干混砂浆,这主要来自三个方面,一是先进的工艺,二是相对早先的板材(EPS、XPS),胶粉聚苯颗粒等保温材料有着绝对的优势,其中之一就是防火,还有一点就是很多人不太在意的就是系统材料的兼容性,三是膨胀玻化微珠保温干混砂浆有很好的耐久性,能和建筑物同寿命,很好的地解决了城市发展和盲目跟风可能产生的很多遗留问题。而JC/T1042—2007《膨胀玻化微珠》则是目前外墙保温无机材料类中唯一一个有国家行业标准的。

At present more mature technology is mainly inorganic insulation mortar expansion vitrified beads insulation dry mortar, it mainly from three aspects, one is the advanced technology, the second is relatively earlier sheet (EPS, XPS), powder polystyrene particles insulation materials such as they have absolute advantages, one of which is fire, there is a lot of people don't care about is the system of material compatibility, 3 it is expanding vitrified beads insulation dry mortar has good durability, can and buildings with life, a good way to solve the urban development and blindly following may produce a lot of legacy. And JC/T1042-2007 "expansion vitrified beads" is currently the only one of exterior wall thermal insulation inorganic materials with national industry standards.

  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。

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.

目前市面上的保温砂浆主要为两种:

Thermal insulation mortar currently on the market are mainly two kinds:

1、无机玻化微珠保温砂浆(简称无机保温砂浆);

1, inorganic vitrified beads insulation mortar (hereinafter referred to as inorganic insulation mortar);

2、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。

2, 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.
