Light building exterior wall fireproof and heat insulating material prepared by slag rock wool

Abstract

The invention discloses light building exterior wall fireproof and heat insulating material prepared by slag wool. The material is characterized by comprising the following components by mass percent: 30 to 60 percent of slag wool, 15 to 30 percent of desulfurized gypsum, 15 to 30 percent of fly ash, and 10 to 20 percent of No. 425 cement. The preparation method comprises the steps that the slag wool and water are mixed in mass proportion of 1:1 and stirred into slag wool slurry; the desulfurized gypsum, the fly ash and the No. 425 cement are mixed according to the mass ratio and put into a proportioning bin to be mixed, proportioned and stirred, so as to be prepared into raw material slurry; the raw material slurry is fed onto a grid type chain conveyer to be molded, so as to be manufactured into wet formed board; and the wet formed board is cut off, dried, cut and shaped, and then the light building exterior wall fireproof and heat insulating material prepared by the slag wool is obtained. The material has the advantages that the problem of poor water absorbance of a slag wool flat plate is solved, the tensile and compression strength is improved, and the phenomena of shrinkage and cracking are avoided. The material integrates light weight, fire resistance, heat insulation and moisture protection, and belongs to novel materials for building walls.

Description

Technical field: [0001] The invention relates to a production method of a lightweight, energy-saving, environment-friendly, flame-retardant, fire-proof and heat-retaining building material product. At the same time, it also relates to the comprehensive utilization of solid waste, and the application of increasing added value in the material of the invention. Background technique: [0002] Building exterior wall insulation materials are divided into inorganic substances and organic substances. Organic substances such as polyurethane and phenolic formaldehyde have good insulation effects, but low fire resistance; large shopping malls, hotels, apartments and other crowded areas are frequently reported all over the country, and the fires caused by them are mostly Caused by external wall insulation materials, it will cause great losses to national property and people's lives. Inorganic materials such as rock wool, cement mortar mixed with polystyrene particles, glass microsphere...

Problems solved by technology

[0002] Building exterior wall insulation materials are divided into inorganic substances and organic substances. Organic substances such as polyurethane and phenolic formaldehyde have good insulation effects, but low fire resistance; large shopping malls, hotels, apartments and other crowded areas are frequently reported all over the country, and the fires caused by them are mostly Caused by external wall insulation materials, causing heavy losses to national property and people's lives

Inorganic materials such as rock wool, cement mortar mixed with polystyrene particles, glass microspheres or simple mixed materials have high fire performance, but basically do not have the effect of heat preservation
