Wall-plastering mortar of architecture fencing wall

Abstract

The invention discloses a plastering mortar of architectural perimeter wall, which comprises the following parts: 70-130g vitrifying microball, 210-390g pearlite, 70-130g coal ash, 280-455g silicate cement, 90-170g aluminate cement, 8-20% redisperse gel powder and 4-8% cellulose, wherein the composite material is 0.7-1.3 times as composite material, which reaches the JG158-2004 standard.

Description

[technical field] [0001] The invention relates to a building material, in particular to a plastering mortar for building enclosure walls. [Background technique] [0002] At present, there are two main types of thermal insulation building materials used at home and abroad to protect the (interior and external) walls of buildings: one is EPS and XPE polystyrene insulation boards; the other is rubber powder polystyrene particle insulation mortar. In foreign countries, EPS and XPE polystyrene insulation boards are a plate structure that combines them with other materials, and is integrally fastened and installed on the building wall with glue and rivets. What our country is promoting is the insulation project that directly uses adhesives and rivets to attach EPS and XPE polystyrene insulation boards to the walls of buildings. Due to the vertical difference of the wall and the aging performance of the glue itself, the bonding strength and anti-aging performance of EPS and XPE po...

AI Technical Summary

Problems solved by technology

If the EPS and XPE polystyrene insulation boards are fastened to the wall with glue and rivets, it is easy to cause water seepage or damage to the wall of the building.

The second is that the polyphenylene particles in the rubber powder polystyrene particle insulation mortar are organic materials, the material is light and has certain elasticity, it is difficult to evenly distribute the rubber powder and polystyrene particles, resulting in poor affinity between polystyrene particles and cement, and When the temperature reaches about 30°, the polystyrene particles will soften, loosen, hollow out, and fall off, so that the rubber powder polystyrene particle insulation mortar can only keep warm without heat insulation effect. When the temperature reaches above 80°, the glue Powdered polyphenylene particles will release a large amount of toxic and harmful volatile gases of benzene, which will bring serious pollution to the environment
