The preparation method of described modified coal ash is as follows: take flyash, diatomite, sepiolite and volcanics by weight 5-10:3-6:2-3:1-2 and mix, below powder particle diameter to 15 μm, then the slurries that concentration is 50-60% are made in the making beating that adds water, add the hydrochloric acid soln adjustment PH to 4-5 that concentration is 10-15%, heating in water bath to 70-80 DEG C, speed lapping 15-20min; Then regulate PH to neutral with the sodium hydroxide solution that concentration is 15-20%, add the tripoly phosphate sodium STPP of sodium lignosulfonate, the trolamine of 2-3%, the spent pulping liquor of 4-6%, the ethoxylated dodecyl alcohol of 2-3% and the 3-5% being equivalent to slurry weight 3-4% again, below speed lapping slurry particle diameter to 10 μm, be spray dried to powder; The sodium polyacrylate of the jade powder of 1-2%, the plant ash of 2-3%, the water glass of 3-5%, the polyvinyl alcohol of 2-3% and 1.5-2.5% is added, speed lapping 5-10min in the most backward powder;
Described water reducer is selected from the one in FDN type high efficiency water reducing agent, UNF type high efficiency water reducing agent, HM type water reducer, AF type high efficiency water reducing agent.
The preparation method of energy-saving light-weight composite sand wiched wall board core material, comprises the following steps:
(1) stir in granules of polystyrene, cement, modified coal ash, sand, water, water reducer, hydroxypropyl methyl cellulose ether raw material input high-speed mixer by above-mentioned formulation ratio, make slurry;
(2) slurry is injected mould solidifying at normal temperatures, after solidification, sheet material base substrate is without the need at high temperature drying kiln inner drying, by test specimen maintenance 3 days in template, then form removable is carried out normal temperature maintenance 28 days.
Beneficial effect of the present invention:
In the present invention, modified coal ash can be used for the replacement cement of part, not only reduces cement consumption, has saved cost, can also improve the flowing property of slurry, improve the performance such as ultimate compression strength, anti-impact force, heat insulating of core material.This core material has that energy-conserving and environment-protective, lightweight economy, intensity are high, heat insulating, sound-adsorbing sound-insulating hung, waterproof and dampproof, fire prevention, antifreeze, shockproof, increase the features such as usable floor area, life-span be long, can ensure that the intensity of sheet material reaches code requirement simultaneously, also there is easy construction, good processability, can saw, dig, follow closely, bore, glue, connect, punch indeformable, reduce the advantages such as wet trade.
Embodiment
A kind of energy-saving light-weight composite sand wiched wall board core material, is made according to the ratio of weight ratio 9:360:72:240:220:7.2:0.36 by High Impact Polystyrene (HIPS) particle, cement, modified coal ash, sand, water, UNF type high efficiency water reducing agent, hydroxypropyl methyl cellulose ether;
