Abstract

The invention discloses a lightweight fireproof and heat-retaining building material, which belongs to the technical field of building material research and development. It consists of the following components in parts by weight: 50-90 parts of cement, 30-70 parts of foam, 3-5 parts of modifier and 5-8 parts of additives. In the thermal insulation building material of the present invention, the foam particles are closely combined with the cement without peeling off. It has the functions of dehumidification, moisture insulation, high-efficiency heat preservation, and fire prevention. This material can be widely used in roof insulation, ground filling of industrial plants, exterior wall insulation, interior wall insulation, floor heating pipeline cushion, wooden floor cushion, and elimination of cold and heat 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...
