Embodiment Construction

[0014] A method for making external wall insulation boards from fluorite slag, in parts by weight, the method includes the following steps:

[0015] 1) Mix 14-16 parts of active filler, 5-8 parts of basalt fiber, 20-30 parts of fluorite slag, and 10-15 parts of calcium carbide slag for crushing, then take 10-12 parts of pulverized coal before fine grinding Ash and 3-5 parts of modified rubber powder are put into a ball mill for fine grinding, and the particle size of the mixture is controlled at 1.5-2.5mm;

[0016] 2) Put the finely ground mixture dry material into the mixing equipment, add 22-30 parts of water to fully stir, and add 5-8 parts of hydrochloric acid solution with a concentration of 18-20%;

[0017] 3) Combine the slurry stirred in the above step (2) at a temperature of 80-100°C with 50-55 parts of cement, 5-8 parts of montmorillonite powder, 4-6 parts of aluminum oxide, and 10-15 parts of high-strength Gypsum, 80-100 parts of water, foaming time 60-80min;

Abstract

The invention discloses a method for preparing an external wall heat preservation plate through fluorite slag. The method comprises the following steps: mixing and crushing 14-16 parts by weight of active packing, 5-8 parts by weight of basalt fibers, 20-30 parts by weight of the fluorite slag and 10-15 parts by weight of carbide slag, and before fine grinding, putting 10-12 parts by weight of fly ash and 3-5 parts by weight of modified rubber powder into a ball grinding machine for fine grinding; (2) putting a dry mixture subjected to fine grinding into stirring equipment, adding 22-30 parts by weight of water for full stirring, and adding 5-8 parts by weight of a hydrochloric acid solution with the concentration being 18-20 percent. By adopting an inorganic-organic combined mode, the defects that an existing organic external wall heat preservation material is combustible, an existing inorganic external wall heat preservation material is high in ratio and high in heat conduction coefficient, and the maintenance middle stage is long, energy consumption is high and the heat preservation effect is poor in a construction or manufacturing process are overcome.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a method for making an external wall insulation board from fluorite slag. Background technique [0002] my country is in a historical period of rapid development of industrialization, urbanization, informatization and agricultural modernization, and the pressure from population, resources and environment is becoming increasingly prominent. Integrating building materials production, construction process and building operation, building energy consumption occupies a high proportion of the final energy consumption of the whole society. Controlling building energy consumption is of vital significance to my country's sustainable development. Use energy-saving technologies, processes, equipment, materials and products to improve thermal insulation performance and the efficiency of heating, air-conditioning, refrigeration and heating systems, strengthen the operation and management...
