Thermal insulation mortar and preparation process thereof
The invention discloses thermal insulation mortar and a preparation process thereof, and belongs to the technical field of building thermal insulation materials. The thermal insulation mortar comprises the following components: a solid component, an additive and water, wherein the solid component is prepared from the following components in parts by mass: 30 to 40 parts of glass beads, 50 to 60 parts of cement and 2 to 8 parts of sepiolite; the additive comprises rubber powder, cellulose ether, an active agent, a thixotropic agent, starch ether, wood fibers, polyphenyl fibers and an air entraining agent; the mass ratio of the water to the solid component is (0.86-1): 1. According to the invention, the vitrified microbeads, the cement and the sepiolite are used as main raw materials and are matched with other additives, so that the thermal insulation mortar with low heat conductivity coefficient and high strength is prepared. And the problems of falling caused by heat preservation of a heat preservation plate and the need of shoveling due to quality change can be avoided. The preparation method provided by the invention is simple, and the heat conductivity coefficient of the prepared thermal insulation mortar is far lower than the standard in GB/T 20473-2021 Building Thermal Mortar.
本发明公开了一种保温砂浆及其制备工艺，属于建筑保温材料技术领域。所述保温砂浆的组分包括：固体组分和外加剂和水；其中，按质量份数计，固体组分包括玻化微珠30～40份、水泥50～60份和海泡石2～8份；外加剂包括胶粉、纤维素醚、活性剂、触变剂、淀粉醚、木质纤维、聚苯纤维和引气剂；水与固体组分的质量比为(0.86～1):1。本发明以玻化微珠、水泥和海泡石为主要原料，配合其他的外加剂，制得了一种导热系数低、强度高的保温砂浆。能够避免采用保温板保温所出现的脱落及因质量改变而需要铲除等问题。本发明提供的制备方法简单，制得的保温砂浆的导热系数远低于GB/T 20473‑2021《建筑保温砂浆》中的标准。
