Lightweight wall plaster

Abstract

The invention discloses a lightweight wall plaster which comprises the following components by weight percent: 65-90% of inorganic cementing material, 5-30% of lightweight aggregate, 0-30% of filler and 0-10% of functional additive, wherein the inorganic cementing material is a desulfurized plaster or a building plaster. The lightweight wall plaster is a single-component dry mixed material produced by a factory and can be used on a construction site by only adding water for stirring, the lightweight wall plaster has a certain thermal insulation function and excellent fire prevention performance, the bonding performance is good, and the compressive strength is high, thereby being capable of replacing the traditional plastering mortar to be plastered on inner sides of external walls, partition walls, room separating walls, ceilings and other occasions and further improving the thermal insulation performance of wall bodies.

Description

technical field [0001] The invention relates to a building material, in particular to a light plaster plaster. Background technique [0002] 1. Indoor wall energy saving [0003] The energy saving of building envelope structure walls can be divided into three categories according to their use parts: external insulation, internal insulation, and self-insulation. [0004] The current wall energy saving in my country is mainly based on external wall insulation (including external wall insulation, external wall internal insulation, and self-insulation). External wall insulation can improve the thermal insulation performance of the whole building and achieve energy saving, but it cannot prevent the internal heat transfer of the building, and the indoor heat loss of the building is inevitable. [0005] It is different from the way of central heating of houses in severe cold and cold areas, hot in summer and cold in winter, hot in summer and warm in winter in hot and humid winter...

Problems solved by technology

[0011] However, replacing traditional mortar with commercial mortar is the need of industrial development, and it does not change the use function of traditional mortar. The cementing material used - cement, its production energy consumption is 4 times that of gypsum; the thermal conductivity of traditional plastering mortar is greater than that of clay solid bricks , no adiabatic function
