Along with the popularization of building energy conservation and people to the improving constantly of living environment comfortableness demand, external thermal insulation system more and more attracts widespread attention.Most widely used external thermal insulation system mainly is comprised of boundary mortar, thermal insulation mortar, anti-cracking plastering mortar, alkali resistant glass fibre open weave cloth, flexible anti-putty and coating etc. on China energy saving building market.Thermal insulation mortar all exists unit weight large at present, thermal conductivity is large, the common faults such as hollowing easy to crack, affect overall appearance and heat insulation effect, have even finish coat comes off, and causes personnel casualty accidents, and social influence is very poor, also there are in addition the shortcomings such as intensity is not high, shock resistance is poor, and all have problems at aspects such as weathering resistance, fire line, green environmental protections.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, but provide the plant ash that a kind of intensity is high, thermal conductivity is low, heat insulation property is good, the good application property of bonding tensile property is good to coat modified Nano sepiolite powder inorganic heat insulation mortar and preparation method thereof.
The technical solution used in the present invention is as follows:
A kind of plant ash coats modified Nano sepiolite powder inorganic heat insulation mortar, is comprised of the raw material of following weight part: 42.5 grades of ordinary Portland cement 50-60, modified coal ash 20-30, plant straw powder 10-20, nanometer sepiolite powder 10-20, plant ash 40-50, starch emulsion 10-15, Di(dioctylpyrophosphato) ethylene titanate 2-3, glass bead 10-15, redispersable latex powder 2-4, hydroxypropyl methyl cellulose ether 0.5-1.5, wood fibre 0.5-1, polyimide fiber 1-2.
Wherein, described modified coal ash is made by following methods: first flyash is dried in 100-110 ℃ of baking oven, then the flyash after will drying is put into the high-speed kneading machine, the stearic acid, the triethyl citrate of 2-3% and the whiteruss of 0.5-1% that add aluminate coupling agent DL-411, the 2-3% of 3-4%, after the high-speed mixing, take out oven dry, grind to form 100-150 order powder and get final product.
The wall outer heat preservation system preparation method of thermal insulation mortar may further comprise the steps:
(1) will add in the high-speed kneading machine with Di(dioctylpyrophosphato) ethylene titanate after the nanometer sepiolite powder drying, speed with 500-800rpm under 105-110 ℃ mixes 20-30min, be cooled to 40-50 ℃, after adding again starch emulsion continuation stirring 10-15min, add plant ash with the speed blend 5-10min of 1000-1500rpm, send into granulation in the tablets press after the oven dry, particle diameter is controlled at 3-5mm, namely gets plant ash clad nano sepiolite powder particle;
(2) powders such as the above-mentioned plant ash clad nano sepiolite powder particle that makes and silicate cement, modified coal ash are put into mortar mixer; under dry state, stir 1-2min; then add glass bead and plant straw powder; restir 2-3min; add again redispersable latex powder, ether of cellulose, wood fibre, polyimide fiber; after stirring 2-3min, the warehouse storage is put in pack.
Be the ratio of 100:30-40 with the above-mentioned thermal insulation mortar that makes according to the mass ratio of mortar and water, blunge can be constructed after stirring.
Beneficial effect of the present invention:
The present invention has improved its dispersiveness in mortar by flyash is carried out modification, thereby improves ultimate compression strength and the shock resistance of mortar.The present invention utilizes plant ash to coat the modified Nano sepiolite powder, thereby improves heat insulation effect and the intensity of mortar by to formula adjustment and process modification, has solved well the contradiction that lagging material intensity and heat-insulating property can not get both.The thermal insulation mortar that the present invention produces has good heat insulation property, workability, intensity is high, good weatherability, the advantages such as environmental protection, be particularly suitable for the communal facility fireproof heat insulatings such as the external and internal wall complex heat-preservation of various brick mix structures, skeleton construction and shear wall structure and vault, garage, stair corridor, fire passage, the building energy conservation Application Areas has the great market space and development prospect in China.
