Background technology
Along with the popularization of building energy conservation and people to the improving constantly of living environment comfortableness demand, lagging material more and more is subjected to people's extensive attention.The lagging material of previously used organic inflammable class is withdrawn from the market fast, as urethane, styrofoam etc.The lagging material of inorganic non-combustible class becomes the main flow of building energy conservation heat insulation, as rock cotton board, glass bead and foaming cement thermal insulation plate etc.And the rock cotton board of mineral-type and glass bead yield poorly, and can not satisfy the demand of society, and simultaneously, rock cotton board is big, big for environment pollution because producing power consumption, and human body can produce injury to health after sucking the rock wool particle.Glass bead is difficult to control because of the former work stone finite sum construction quality of producing, thereby can not shoulder a heavy task for building heat preservation market branch.Therefore, cement foamed warming plate is large material by using cement, flyash etc., can gather materials on the spot, and output is big, will become the main product of building thermal insulation material.Yet the cement foamed plate majority on the existing market is main raw material with the aluminosulfate cement, makes this product exist early strength high relatively, and the later strength decay is big, and capacity is high relatively (mostly to be 250kg/m
3-300kg/m
3), heat-insulating property relative mistake, water-intake rate are high relatively, and fragility is big, shortcomings such as weather resistance relative mistake.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of light weight, high insulating effect, cement foamed plate that weather resistance is strong and preparation method thereof are provided.
The technical solution used in the present invention is as follows:
A kind of light cement foaming insulation board is made up of the raw material of following weight part: 52.5 ordinary Portland cement 70-80, flyash 40-50, silica flour 30-40, river sand 15-20, fluorite slag 10-15, potter's clay 5-10, plant straw powder 15-20, water glass 18-25, vermiculite 20-30, whipping agent 8-12, suds-stabilizing agent 1-2, Natvosol 1-2, modification trees ashes 3-5, high performance water reducing agent of polyocarboxy acid 1-2, water 300-360.
Described modification trees ashes are made by following method: earlier with 10-15% hydrogen peroxide dipping trees ashes 1-2h, clean with distilled water again, dehydration, add the paregal O of the titanate coupling agent TMC-TTS, the 2-3% that are equivalent to trees ashes weight 1-2%, the sodium laurylsulfate of 3-4%, the nanometer sepiolite powder of 4-6%, high speed dispersion 20-30min, drying, pulverizing grinds to form ultrafine powder and gets final product.
The preparation method of light cement foaming insulation board may further comprise the steps:
(1) will add in the high-speed mixer with Natvosol after the vermiculite drying, speed with 500-800rpm mixes 20-30min at normal temperatures, after adding water glass continuation stirring 10-15min again, add plant straw powder, clay with the speed blend 5-10min of 1000-1500rpm, send into granulation in the tablets press, particle diameter control namely gets plant straw powder and coats vermiculite granule at 3-5mm, and is stand-by;
(2) the above-mentioned plant straw powder coating vermiculite granule that makes and 52.5 ordinary Portland cements, flyash, silica flour, river sand, fluorite slag, potter's clay, modification trees ashes, suds-stabilizing agent, high performance water reducing agent of polyocarboxy acid, water are dropped in the high-speed mixer and stir, form mixed slurry;
(3) in the mixed slurry that stirs, add whipping agent, inject the mould container of briquet behind the stirring 20-30s, and solidify 20-30min at 40-45 ℃ of thermophilic;
(4) the foam cement slab piece that take out to solidify of the demoulding placed under the natural condition maintenance 25-30 days, adopted cutting machine, by the cement foamed board finished product of dimensions requirements cutting formation, and packed.
Described whipping agent is hydrogen peroxide; Described suds-stabilizing agent is calcium stearate.
Beneficial effect of the present invention:
The present invention utilizes plant straw powder to coat silica flour, thereby improves heat insulation effect and the intensity of cement foamed plate by to formula adjustment and process modification, has solved the contradiction that cement foamed plate intensity and heat-insulating property can not get both well.The cement foamed plate that the present invention produces has excellent insulating thermal insulation, workability, and adhesive effect is good, no hollowing cracking phenomena, and the wind suction prevention ability is strong, intensity height, light weight resistance to compression, good weatherability, environmental protection and energy saving, advantage such as nontoxic.The building energy conservation Application Areas has the great market space and development prospect in China.
