Abstract

The invention provides rendering mortar for an exterior-wall heat insulation thin plastering system. The rendering mortar is prepared from the following components in percentages by weight: 25.0 to 35.0 percent of ordinary portland cement, 45.0 to 71.0 percent of ore sand, 2.0 to 10.0 percent of auxiliary material and 2.0 to 10.0 percent of accessory ingredient, wherein the ordinary portland cement is portland cement of which the strength grade is P.O 42.5 or above; the ore sand is graded quartz sand of 70 to 140 meshes; the auxiliary material is one or the mixture of pulverized fuel ash and coarse whiting; the auxiliary ingredient can be formed by cooperating redispersible latex powder, cellulose ether, a PP (Polypropylene) fiber, a wood fiber, a water repellent, a thixotropic agent and metakaolin. By using the rendering mortar for the exterior-wall heat insulation thin plastering system, which is provided by the invention, a rendered mortar layer can be enabled to be compact and be high in strength, is good in flexibility performance and anti-cracking performance and good in workability, fluidity and water retention, and has a better hydrophobic effect; the whiskering rate of the rendered mortar layer is greatly decreased; the rendering mortar for the exterior-wall heat insulation thin plastering system, which is given by the application, is high-flexibility, high-water-resistance and low-whiskering-rate rendering mortar; the inventive purpose of the application can be realized.

Description

technical field [0001] The invention relates to building materials, and belongs to the technical field of energy-saving and thermal insulation of building exterior walls. More specifically, it relates to a plastering mortar for an external wall thermal insulation thin plastering system and a manufacturing method and a construction method thereof. Background technique [0002] With the rapid development of the building exterior wall insulation industry, everyone's requirements for insulation system materials are also getting higher and higher. Plastering mortar refers to the mortar applied on the surface of buildings and building components. It plays an important role in the external thermal insulation system of external walls. The plastering mortar used in the thin plastering system of external wall thermal insulation forms a plastering mortar layer, which can protect the thermal insulation core material. Protection to improve the durability and safety of external wall insul...
