Method for manufacturing plastering mortar for external walls of buildings

Abstract

The invention relates to a method for manufacturing plastering mortar for external walls of buildings. The plastering mortar comprises, by weight, 50-70% of river sand, 15-40% of cement, 3-6% of polystyrene adhesive powder, 0.3-0.9% of alkali-resistant glass fibers, 0.2-0.6% of modified saline water retentive agents and 6-12% of components C. The method includes mixing the river sand, the cement, the polystyrene adhesive powder, the alkali-resistant glass fibers and the modified saline water retentive agents with one another and uniformly stirring the river sand, the cement, the polystyrene adhesive powder, the alkali-resistant glass fibers and the modified saline water retentive agents to obtain mixtures; adding the components C into the mixtures; uniformly mixing the mixtures and the components C with one another to obtain the plastering mortar for the external walls of the buildings. The method has the advantages that the mortar manufactured by the aid of the method can be used for wall surfaces of the buildings, accordingly, temperatures can be automatically regulated according to temperature variation, the plastering mortar is good in energy storage performance and thermal engineering performance and stable in physical and chemical properties, and obvious energy saving effects can be realized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method of plastering mortar for building exterior walls. Background technique [0002] Building energy conservation is a long-term strategic policy and basic national policy formulated by our country, and it is the ultimate goal of sustainable development of resources in our country. In the past 20 years, my country's social and economic development level has achieved world-renowned improvement, but in terms of building energy efficiency, compared with Western industrial countries, the gap is still very large. The energy consumption per unit building area in my country is three times that of developed countries with similar climatic conditions, and 95% of buildings are high-energy buildings. Reducing the heat transfer coefficient of building envelope walls is one of the main measures and effective means of building energy conservation. Building exterior...

Problems solved by technology

At present, the domestic external wall insulation system mainly includes two types of insulation board and insulation mortar. Although the insulation board has the advantages of low thermal conductivity and good thermal insulation performance, it is difficult to construct, high in technical requirements, high in cost and low in strength.
