The preparation method of described modified coal ash is as follows: by weight 5-10:3-6:2-3:1-2, take flyash, diatomite, sepiolite and volcanics and mix, below powder particle diameter to 15 μ m, then add water making beating and make the slurries that concentration is 50-60%, adding concentration is the hydrochloric acid soln adjusting PH to 4-5 of 10-15%, heating in water bath is to 70-80 ℃, speed lapping 15-20min; Then the sodium hydroxide solution that is 15-20% by concentration regulates PH to neutral, add again and be equivalent to the sodium lignosulfonate of slurry weight 3-4%, the trolamine of 2-3%, spent pulping liquor, the ethoxylated dodecyl alcohol of 2-3% and the tripoly phosphate sodium STPP of 3-5% of 4-6%, below speed lapping slurry particle diameter to 10 μ m, be spray dried to powder; In the most backward powder, add the jade powder of 1-2%, the plant ash of 2-3%, water glass, the polyvinyl alcohol of 2-3% and the sodium polyacrylate of 1.5-2.5% of 3-5%, speed lapping 5-10min;
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 core material for energy-saving light-weight composite sand wiched wall board, comprises the following steps:
(1) by above-mentioned formulation ratio, granules of polystyrene, cement, modified coal ash, sand, water, water reducer, hydroxypropyl methyl cellulose ether raw material are inputted in high-speed mixer and stirred, make slurry;
(2) slurry injected to mould and solidify at normal temperatures, after solidifying, sheet material base substrate without at high temperature drying kiln inner drying, by test specimen maintenance 3 days in template, then carries out normal temperature maintenance 28 days by form removable.
Beneficial effect of the present invention:
In the present invention, modified coal ash can be used for the replacement cement of part, has not only reduced cement consumption, has saved cost, can also improve the flowing property of slurry, improves 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 guarantee 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;
The preparation method of described modified coal ash is as follows: by weight 8:4:3:1, take flyash, diatomite, sepiolite and volcanics and mix, below powder particle diameter to 15 μ m, then adding water making beating, to make concentration be 55% slurries, add concentration and be 15% hydrochloric acid soln and regulate PH to 4.5, heating in water bath to 75 ℃, speed lapping 15min; Then the sodium hydroxide solution that is 16% by concentration regulates PH to neutral, add again sodium lignosulfonate, 2% trolamine, 5% the spent pulping liquor, 3% ethoxylated dodecyl alcohol and 4% the tripoly phosphate sodium STPP that are equivalent to slurry weight 3%, below speed lapping slurry particle diameter to 10 μ m, be spray dried to powder; In the most backward powder, add 1.5% jade powder, 2% plant ash, 4% water glass, 2% polyvinyl alcohol and 2% sodium polyacrylate, speed lapping 8min;
