The prefabricated mortar of lightweight, primarily of cement, desulfurated plaster, slag, then adds a small amount of perlite powder, adds water and stirs and become. Then inject in the required product mold produced. Getting final product the demoulding after spending 15 minutes, if room temperature adds a little naphthalene water reducer lower than when 10 DEG C, the exhaust gas flue produced like this or lightweight partition wall product, have that weight is light, intensity good, flawless and a fire performance advantages of higher.
Summary of the invention
The present invention is directed to the problems referred to above, it provides a kind of water mixes the prefabricated mortar of lightweight.
The technical solution used in the present invention is: a kind of water mixes the prefabricated mortar of lightweight, is made up of cement, desulfurated plaster, slag, perlite particle, water, iron oxide yellow powder, aluminum oxide powder, faling apart property latex powder and glass fiber; Described cement, desulfurated plaster, slag, perlite particle, water, iron oxide yellow (molecular formula Fe2O3·xH2O) powder, aluminum oxide (Al2O3) powder, faling apart property latex powder and glass fibre weight ratio be: 5-25:35-45:5-10:1-5:35-40:0.1-0.5:0.1-0.5:0.1-0.5:0.1-0. 5.
The advantage of the present invention:
The present invention mixes in the prefabricated mortar of lightweight at water and adds iron oxide yellow powder and aluminum oxide powder, it is to increase product strength, corresponding shortening demould time, it is to increase fire performance.

The situation of inspection exhaust gas flue product is that product proportion is 790Kg/m3. Be its weight of example by the flue of 400mm*500mm length 3000mm thickness 15mm be 64Kg/ root, the anti-soft impulse test of its product surface flawless, 10Kg sandbag drop 1m same position impact 5 times after goods without cracking, pipe body vertical bearing capacity 96KN. The thickness 120mm lightweight partition wall produced by above proportioning is spent 27 days and is naturally dried rear (without the need to water curing) assay, its weight 72Kg/ (lightweight partition wall is middle hole) plate face is without natural crackle, impact test, 5 plate face leakless are impacted in the swing bearing 30Kh sandbag drop 0.5m, hanging force is tested, by 1000N single-point hanging force effect 24h, around the sling point of plate face, leakless is with damaged, the bad load retention rate (weather resistance) 75% of anti-folding.
Embodiment 2
The weight ratio of cement in the prefabricated mortar of described lightweight, desulfurated plaster, slag, perlite particle, water, iron oxide yellow powder, aluminum oxide powder, faling apart property latex powder and glass fiber is 15:38:8:4:34:0.3:0.3:0.2:0.2. The prefabricated exhaust gas flue of lightweight produced according to this component proportions is after 27 days dry naturally (without the need to water curing). Its product surface flawless, proportion is 890Kg/m3400mm*500mm specification its weight 73Kg/ root of length 3000mm thickness 15mm, and anti-soft impulse is tested, 10Kg sandbag drop 1m same position impact 9 times after goods without cracking, pipe body vertical bearing capacity 98KN.
