Bonding powder expanded polystyrene granule insulating mortar suitable for thick plastering and compacting construction

Abstract

The invention relates to a bonding powder expanded polystyrene granule insulating mortar suitable for thick plastering and compacting construction, which is composed of the following components in parts by weight: 5-20 parts of bonding powder or polyoxyethylene, 250-650 parts of silicate cement, 200-500 parts of activated coal ash, 50-100 parts of bentonite, 1-5 parts of polycarboxylic acid water reducing agent, 3-70 parts of wood fiber or asbestos wool, 2-10 parts of waste polystyrene foam or waste phenolic aldehyde foam or waste polyurethane rigid foam granules which are 3-5mm in diameter, and 10-20 parts of water. According to the scheme, the optimal combination of the formula is realized; the bonding strength on a substrate is greatly improved; an insulating layer having a thickness of 100mm or above can be obtained through one-step plastering; the defect of spending too much time due to the conventional adoption of a layered plastering and compacting technology according to the design thickness is overcome; and the construction cycle is greatly shortened, and the construction process is simplified. Thus, the bonding powder expanded polystyrene granule insulating mortar can be widely used in the field of reconstructing and newly constructing outer wall outer insulating layers, outer wall inner insulating layers and outer / inner wall simultaneously-combined insulating layers of civil buildings.

Description

technical field [0001] The invention relates to an energy-saving heat-insulating and heat-insulating material formula applied to building walls, in particular to a polyphenylene particle heat-insulating slurry. Background technique [0002] Insulation materials for building applications are mainly divided into organic type, inorganic type and composite type (that is, rubber powder polystyrene particle insulation slurry). The performance and application of various types of insulation materials have their own advantages and disadvantages. At present, the product standard of rubber powder polystyrene particle thermal insulation slurry (JG158-2004) is adopted. During construction, it must be applied several times to reach the design thickness, and then another plastering layer of anti-cracking polymer mortar is used. Paint finish or tile finish layer. The specific process is as follows: during the construction, the next application must be done 24 hours after the previous appli...

Problems solved by technology

Due to the high thermal conductivity, the coating thickness of the wall rubber powder polystyrene particle insulation slurry layer is increased, and it is not suitable for external wall insulation in severe cold regions and cold regions, so the scope of use is limited.
