Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide that a kind of intensity is high, thermal conductivity is low, heat insulation property is good, bonding tensile property is good, can application property good coated modified Nano diatomite inorganic heat insulation mortar of plant ash and preparation method thereof.
The technical solution used in the present invention is as follows:
Plant ash is coated a modified Nano diatomite inorganic heat insulation mortar, the raw material of following weight part, consists of: 42.5 grades of ordinary Portland cement 50-60, colliery powder 20-30, plant straw powder 10-20, nano diatomite 10-20, plant ash 40-50, starch emulsion 10-15, tetra isopropyl two (dioctyl phosphorous acid acyloxy) titanic acid ester 2-3, modified vitrification micro-bead 10-15, redispersable latex powder 2-4, hydroxyethylmethyl-cellulose ether 0.5-1.5, wood fibre 0.5-1, polypropylene fibre 1-2.
Described modified vitrification micro-bead is made by following methods: glass bead is added in high-speed mixer; sec.-propyl three (dioctylphyrophosphoric acid acyloxy) titanic acid ester that adds 2-3%; high-speed stirring 20-30min at 100-110 ℃; getting the resol that is equivalent to glass bead weight 40-50% is dissolved in ethanol solution again; then it is evenly coated in to the surface of glass bead; be placed at 150-160 ℃ and solidify 0.5-1h, obtain modified vitrification micro-bead.
The preparation method of the coated modified Nano diatomite inorganic heat insulation mortar of plant ash, comprises the following steps:
(1) nano diatomite is afterwards dry and tetra isopropyl two (dioctyl phosphorous acid acyloxy) titanic acid ester adds in high-speed kneading machine, speed with 500-800rpm at 105-110 ℃ is uniformly mixed 20-30min, be cooled to 40-50 ℃, add again starch emulsion to continue to stir after 10-15min, add plant ash with the speed blend 5-10min of 1000-1500rpm, after oven dry, send into granulation in tablets press, particle diameter is controlled at 3-5mm, obtains plant ash clad nano diatomite particle;
(2) powders such as the above-mentioned plant ash clad nano diatomite particle making and silicate cement, colliery powder are put into mortar mixer; under dry state, stir 1-2min; then add modified vitrification micro-bead and plant straw powder; stir again 2-3min; add again redispersable latex powder, ether of cellulose, wood fibre, polypropylene fibre; stir after 2-3min, pack, puts into warehouse storage.
The ratio that is 100:30-40 according to the mass ratio of mortar and water by the above-mentioned thermal insulation mortar making, blunge, can construct after stirring.
Beneficial effect of the present invention:
The present invention is by carrying out the coated modification of resol to glass bead; make glass bead show more excellent performance; cylindrical compress strength significantly improves; water-intake rate reduces greatly; keep heat-insulating property and low-density characteristic that glass bead is good simultaneously, effectively reduced the breakage rate of glass bead in the course of processing.The present invention, by formula adjustment and process modification, utilizes plant ash to be coated modified Nano diatomite, thereby improves heat insulation effect and the intensity of mortar, 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, in China, building energy conservation Application Areas has the great market space and development prospect.
