Abstract

The invention discloses a steel fiber enhanced foam concrete heat insulation board for a roof. The steel fiber enhanced foam concrete heat insulation board is characterized by being prepared from, by weight, 500 parts of electric furnace phosphorus slag, 100-120 parts of fly ash, 50-60 parts of sepiolite, 20-30 parts of polyving akohol, 3-4 parts of cocamidopropyl betaine, 12-15 parts of ferric chloride solution, 12-15 parts of vinyl acetate monomer, 8-10 parts of acetylacetone titanium, 25-30 parts of steel fiber, 120-150 parts of acetone, 20-25 parts of sodium hydroxide, 10-12 parts of zinc phosphate, 8-10 parts of ammonium molybdate, 20-30 parts of cement, 6-8 parts of lauryl sodium sulfate, 20-30 parts of strisilane, 30-40 parts of ammonium bicarbonate, and proper amount of water. The a steel fiber enhanced foam concrete heat insulation board for the roof is featured by light weight, low cost, high intensity, convenience in construction and installation, and outstanding heat insulation, heat isolation and sound insulation effects.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a steel fiber reinforced foam concrete insulation board for roofing and a preparation method thereof. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Foamed concrete is to introduce air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it forms a concrete with a large number of small closed pores and has considerable strength. products. [0003] Because foam concrete contains a large number of closed small pores, it has good thermal performance, that is, good thermal insulation performance, which is not available in ordinary ...
