Description
Technical field
The present invention relates to a kind of light cement foaming insulation board and preparation method thereof, belong to building material field.
Background technology
Along with popularization and people's improving constantly living environment comfortableness demand of building energy conservation, lagging material more and more attracts widespread attention.The lagging material of the organic inflammable class of use is in the past withdrawn from the market, fast as urethane, styrofoam etc.The lagging material of inorganic non-combustible class becomes the main flow of building energy conservation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 cement insulation board etc.And the rock cotton board of mineral-type and glass bead yield poorly, can not meet the demand of society, meanwhile, rock cotton board is large, big for environment pollution because producing power consumption, can produce injury after human body sucks rock wool particle to health.Glass bead is difficult to control because of the raw material stone finite sum construction quality of producing, thus can not divide for building heat preservation market and shoulder a heavy task.Therefore, cement foaming insulation board is large material by using cement, flyash etc., can gather materials on the spot, and output is large, will become the main product of building thermal insulation material.But the cement foam board majority on existing market is main raw material with aluminosulfate cement, makes this product there is early strength relatively high, later strength decay is large, and capacity relative is high (mostly is 250kg/m
3-300kg/m
3), heat-insulating property relative mistake, water-intake rate is relatively high, and fragility is large, the shortcomings such as weather resistance relative mistake.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, cement foam board that a kind of light weight, high insulating effect, weather resistance are strong and preparation method thereof is 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 tree ash 3-5, high performance water reducing agent of polyocarboxy acid 1-2, water 300-360.
Described modification tree ash is obtained by following methods: first use 10-15% hydrogen peroxide dipping tree ash 1-2h, clean with distilled water again, dehydration, add the paregal O of titanate coupling agent TMC-TTS, the 2-3% being equivalent to tree ash weight 1-2%, the sodium laurylsulfate of 3-4%, the Nano sepiolite powder of 4-6%, high speed dispersion 20-30min, dry, pulverize and grind to form ultrafine powder.
The preparation method of light cement foaming insulation board, comprises the following steps:
(1) add in high-speed mixer by after vermiculite drying with Natvosol, 20-30min is uniformly mixed at normal temperatures with the speed of 500-800rpm, after adding water glass continuation stirring 10-15min again, add plant straw powder, clay with the blended 5-10min of the speed of 1000-1500rpm, send into granulation in tablets press, size controlling, at 3-5mm, obtains the coated vermiculite granule of plant straw powder, stand-by;
(2) the coated vermiculite granule of above-mentioned obtained plant straw powder and 52.5 ordinary Portland cements, flyash, silica flour, river sand, Fluorite slag, potter's clay, modification tree ash, suds-stabilizing agent, high performance water reducing agent of polyocarboxy acid, water are dropped in high-speed mixer and stir, form mixed slurry;
(3) in the mixed slurry stirred, add whipping agent, after stirring 20-30s, inject the mould container of briquet, and at 40-45 DEG C of thermophilic solidification 20-30min;
(4) the cement board briquet that solidification is taken out in the demoulding is placed in maintenance 25-30 days under natural condition, adopts cutting machine, by the cement foamed board finished product of dimensions requirements cutting formation, and packs.
Described whipping agent is hydrogen peroxide; Described suds-stabilizing agent is calcium stearate.
Beneficial effect of the present invention:
The present invention by formula adjustment and process modification, utilizes the coated silica flour of plant straw powder, thus improves heat insulation effect and the intensity of cement foam board, solves the contradiction that cement foam board intensity and heat-insulating property can not get both well.The cement foam board that the present invention produces has excellent heat insulation property, workability, and adhesive effect is good, and without hollowing cracking phenomena, wind suction prevention ability is strong, and intensity is high, light weight resistance to compression, good weatherability, environmental protection and energy saving, the advantage such as nontoxic.In China, building energy conservation Application Areas has the great market space and development prospect.
