Abstract

The invention discloses an environment-friendly type construction water resistant thermal insulating mortar prepared from cement, polymer emulsion powder, discarded polyphenylacetylene, polypropylene fiber, alta-mud, water-based silane / siloxane emulsion, quartz sand and water with right weight ratio through finite process. The mortar has fine thermal insulation property, chemical-resisting, waterproof and barrier properties.

Description

technical field [0001] The invention belongs to the technical field of building materials and chemistry, and relates to an environment-friendly building waterproof and thermal insulation mortar for construction engineering, in particular to a kind of thermal insulation of internal and external walls of buildings, especially waste polystyrene used in waterproof and impermeability engineering for external thermal insulation of external walls Foam insulation mortar. Background technique [0002] With the continuous improvement of environmental protection and energy conservation requirements, the thermal insulation technology of building envelope has become one of the important building energy-saving technical approaches in our country. A variety of wall composite thermal insulation technologies have been developed. Building thermal insulation mortar is an important method of wall thermal insulation. At present, thermal insulation materials for thermal insulation mortar mainly i...
