Abstract

The invention relates to a method for preparing basalt fiber reinforced foam glass. The method includes the following steps that firstly, glass powder and fly ash pass a 200-mesh screen for use; secondly, 70-80 parts by mass of glass powder obtained in the first step, 20-30 parts by mass of fly ash obtained in the first step, 0.151-0.757 part by mass of basalt fiber, 2-6 parts by mass of sodium carbonate, 2 parts by mass of trisodium phosphate, 2 parts by mass of borax and 30-35 parts by mass of water are weighed and evenly mixed to prepare a mixed material; thirdly, the mixed material obtained in the second step is placed in a high-temperature-resistant mould and then vibrated for 5-10 min on a vibrating table; fourthly, the vibrated mould is placed in an oven and dried for 0.5-2 h at 100 DEG C to obtain a blank; fifthly, the blank obtained in the fourth step is fired at 840-850 DEG C, and the basalt fiber reinforced foam glass is obtained.

Description

Technical field [0001] The invention belongs to the field of material science and engineering, and relates to a preparation method of inorganic heat insulating materials, in particular to a preparation method of basalt fiber reinforced foam glass. Background technique [0002] With the rapid development of my country's economy, the issue of building energy conservation has received increasing attention. The application of building insulation materials can effectively reduce the overall energy consumption of the building, and the energy is used more efficiently. Building thermal insulation materials mainly include organic and inorganic materials. The production technology of organic thermal insulation materials has been relatively mature and has a high use rate in building exterior wall thermal insulation. However, organic thermal insulation materials are flammable and easily deformed by heat, which poses safety risks. Foam glass is an inorganic thermal insulation material, which...
