Problems solved by technology

[0002] Building roofs, floors, and walls are generally made of slag, polystyrene, rock wool and other materials to complete insulation, which has poor adhesion, flammability, and low strength.
Processing, transportation, and storage are extremely inconvenient and costly, especially the ground insulation is mostly made of slag paved 40-50 thick, its bulk density is high, and the roof frame has to bear a lot of pressure

Embodiment 1

[0044] First, the slag waste clay bricks are broken into particles of different particle sizes by a hammer crusher, and the 1-3mm particle slag is separated into 0.18m 3 ;3-5mm granular slag 0.135m 3 ;8-15mm granular slag 0.315m 3 ; 1-3mm particle broken brick 0,07m 3 ; 3-5mm particle broken brick 0.05m 3 ; 8-15mm particle broken brick 0.15m 3 ; Sprinkle water separately for later use; then add 0.7m 3 Expanded perlite particles, 40 kg of first-grade fly ash and 150 kg of 32.5 ordinary Portland cement are put into the mixer and mixed well, then 5.0 kg of organic silicon water repellent and water are added to mix into a semi-dry state, and passed through the rolling mixer Secondary mixing, and finally put into the mold and pressed.

Abstract

This invention relates to a new type of heat-insulating boards of light aggregate concrete, in which, 0.16m3-0.19m3 slag of 1-3mm grains, 0.12-0.14m3 of 3-5mm slag, 0.30.3-0.33m3 of 8-15mm, 0.06m3-0.08m3 rubbles of 1-3mm, 0.04-0.06m3 rubbles of 3-5mm and 0.14-0.16m3 rubbles of 8-15mm are watered and ready to be used, then 0.65m3-0.75m3 expanded perlite grains, 30-50kg first level fly ash and 120-180 kg ordinary Portland cement are put in a mixer to be mixed then to be pressed in a die.

Description

technical field [0001] The invention relates to a new type of building insulation material. Background technique [0002] Building roofs, floors, and walls are generally insulated from materials such as slag, polystyrene, and rock wool, which have poor adhesion, are flammable, and have low strength. Processing, transportation, and storage are extremely inconvenient and costly. In particular, most of the ground insulation is paved with slag 40-50 thick, and its bulk density is high, so the roof frame has to bear great pressure. Contents of the invention [0003] In view of the above existing problems, the object of the present invention is to provide an energy-saving light aggregate concrete insulation board for buildings. The product has high strength and strong thermal insulation performance. The material used is non-flammable inorganic material, non-toxic, tasteless, good hydrophobicity, high waste rate, low cost, and convenient for processing, storage and transportatio...
