Example Embodiment

[0014] A kind of moisture-proof cement hollow brick, made of the following weight (kg) raw materials: fluoroaluminate cement 66, anorthite 24, organosilicon microspheres 6, nickel iron slag 21, mineral wool scrap 17, yellow river silt 22, Heavy calcium powder 12, polyethylene waste 7, crushed stone 15, boiler ash 17, sodium stearate 5, phosphate rock tailings 12, polyamide wax powder 4, blast furnace water quenching slag 16, waste tire rubber powder 8, poly Acrylamide 11, lithium fluoride 4.5, tungsten tailings 12, sodium tripolyphosphate 6, water appropriate.

[0015] A method for preparing moisture-proof cement hollow bricks includes the following steps:

[0016] (1) Mix the nickel-iron slag, Yellow River sludge, crushed stone chips, and tungsten tailings evenly, crush them, pass through a 60-mesh sieve, add an appropriate amount of water, stir well, make a ball, and control the particle size to 4mm. The raw meal balls are dried at 95°C until the moisture content is below 1%, an...

Abstract

The invention discloses a moisture-proof cement hollow brick and a preparation method thereof. The moisture-proof cement hollow brick is prepared from the following raw materials (by weight): 57-69 parts of fluoraluminate cement, 21-27 parts of anorthite, 4-9 parts of organosilicon microspheres, 17-24 parts of ferronickel slag, 13-21 parts of mineral wool leftover, 18-26 parts of the Yellow River silt, 10-15 parts of heavy calcium powder, 5-10 parts of waste polyethylene, 12-19 parts of gravel chippings, 15-20 parts of boiler ash, 4-6 parts of sodium stearate, 8-16 parts of phosphorus tailings, 3-5 parts of polyamide wax micro-powder, 14-22 parts of blast furnace water-quenched slag, 5-10 parts of waste tire rubber powder, 7-14 parts of polyacrylamide, 3-5 parts of lithium fluoride, 10-15 parts of tungsten tailings, 4-7 parts of sodium tripolyphosphate and a proper amount of water. By the addition of raw materials including organosilicon microspheres, waste polyethylene, sodium stearate, polyamide wax micro-powder, waste tire rubber powder, etc., water absorption of the cement hollow brick is significantly reduced, and humidity resistance of the cement hollow brick is then enhanced.

Description

technical field [0001] The invention relates to a hollow brick and a preparation method thereof, in particular to a moisture-proof cement hollow brick and a preparation method thereof. Background technique [0002] Cement hollow brick is a new type of wall material, which has the advantages of light weight, high strength and good thermal insulation performance. The production and use of this new type of wall material can achieve the purposes of energy saving, land saving, water saving, waste utilization, increasing the effective use area of ​​buildings, shortening the construction period, etc. It has incomparable advantages over traditional clay bricks and is a substitute for solid clay bricks. One of the preferred materials for bricks is strongly supported by the national industrial policy. However, the current cement hollow bricks still have the disadvantage of poor moisture-proof performance, and are easily damaged after long-term use in a humid environment, thereby shor...
