Abstract

The invention discloses an inorganic phenolic aldehyde composite thermal mortar which comprises 90-100 parts of cement, 8-18 parts of silica fume, 30-50 parts of phenolic foam particles, 100-120 parts of expanded and vitrified small balls, 4-6 parts of redispersible powder, 1.2-1.8 parts of cellulose ether, 2.5-3.5 parts of lignocellulose, and 0.8-1.2 parts of PP fibers. The phenolic foam particles are subjected to alkali neutralization and water-proof treatment, so that the corrosion on a wall body and the water absorption rate are improved. The composite thermal mortar not only keeps the advantages of excellent construction performance, high compression strength and high combustion performance grade up to A2 level of the inorganic thermal mortar, but also is lower in dry density and thermal conductivity, thereby being a good thermal insulation material having the advantages of good energy saving effect and high level of combustion performace grade and capable of being widely applied to the thermal insulation construction of a building outer wall.

Description

technical field

[0001] The invention belongs to the field of building energy saving and heat preservation, and relates to an inorganic phenolic composite heat preservation mortar. Background technique

[0002] Building energy conservation is an important part of energy conservation and emission reduction in the whole society. The performance and structural stability of building energy conservation systems are directly related to the implementation of energy conservation and emission reduction work and the realization of goals. At present, the building energy-saving systems used in my country mainly include inorganic thermal insulation mortar systems, expanded polystyrene board systems, extruded polystyrene board systems, and polyurethane systems. The inorganic thermal insulation mortar system has the advantages of good construction performance, high strength, A2 level of combustion performance, and low overall cost, but its high thermal conductivity makes it difficult to mee...
