Abstract

The invention discloses a light fireproof thermal-insulation building material, and belongs to the technical field of research and development of building materials. The light fireproof thermal-insulation building material is composed of the following ingredients in parts by weight: 50-90 parts of cement, 30-70 parts of foam, 3-5 parts of a modifier and 5-8 parts of an additive. In the thermal-insulation building material disclosed by the invention, foam particles and cement are combined closely, so that no peeling is realized. The light fireproof thermal-insulation building material has the functions of dehumidification, damp prevention, efficient thermal insulation and fire prevention, can be widely applied to roof thermal insulation, ground filling of industrial plants, external wall thermal insulation, internal wall thermal insulation, floor heating pipeline cushion layers, wooden floor cushion layers and elimination of hot and cold bridges.

Description

technical field [0001] The invention belongs to the technical field of research and development of building materials, and in particular relates to a lightweight fireproof and heat-retaining building material. Background technique [0002] Polystyrene, molecular formula C 8 h 8 , mainly used for foam molding, used as thermal insulation, heat insulation, shockproof, packaging materials and floating products. The general-purpose type is suitable for packaging materials, and the flame-retardant type is suitable for construction and heat insulation materials. Polystyrene is foamed into spherical particles, which is a foam. The foam is light in weight and has good heat insulation performance. It can be added to cement materials and mixed with cement, and dried in the sun to prepare lightweight building materials. It has heat preservation, fire prevention, waterproof, etc. performance. However, because the polystyrene material is too light, when it is mixed with cement and oth...
