Abstract

The invention discloses a hollow vitrified micro bubbles heat preservation and insulation composite material which comprises vitrified micro bubbles and a cementing material, the vitrified micro bubbles are taken as a light aggregate of mixed mortar and mixed with the cementing material. The hollow vitrified micro bubbles heat preservation and insulation composite material is characterized in that contents of the vitrified micro bubbles and the cementing material are 20-50 parts of the vitrified micro bubbles and 40-55 parts of the cementing material respectively; the cementing material is a mixture of cement, sand, a foaming agent and a water-proofing agent, and the cementing material consists of the 40-60 parts of the cement, 2.5-3.3 parts of the sand, and a proper amount of the foaming agent and the water-proofing agent. The hollow vitrified micro bubbles heat preservation and insulation composite material has the advantages of good heat preservation, heat insulation, fire prevention and construction properties, is insusceptible to the biting of insects and ants, and is economical and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of building materials, and more specifically relates to thermal insulation materials for walls. Background technique [0002] At present, from the perspective of the main insulation materials of existing structural walls, glass wool, polystyrene foam boards and polyurethane foam boards are commonly used. The wall insulation structure using polystyrene foam board is the base wall, adhesive, polystyrene foam board, reinforced mesh cloth, primer, putty, and finishing layer. The technical structure of polyurethane spraying exterior wall insulation is base wall, polyurethane primer, polyurethane insulation layer, front mortar, light leveling layer, anti-cracking mortar composite grid cloth, putty, and exterior wall coating. The glass wool material has the problems of troublesome construction and poor thermal insulation performance. Polystyrene foam boards and polyurethane foam boards have defects such as comple...
