The high-performance heat-preservation thermal-insulation wall material has a sand ratio of 39-42%, contains 0.2-0.5% of silicon oxide aerogel based on dry materials, contains a water reducer of which the use amount is determined according to fluidity and has a water-binder ratio of 0.45-0.50. The preparation method comprises dispersing prepared silicon oxide aerogel in water, uniformly mixing cement, ceramsite, blast furnace slag and fly ash according to the above ratio to obtain a uniform mixture, adding a water reducer into water, carrying out strong stirring, carrying out casting according to a certain volume ratio and carrying out maintenance to obtain the high-performance heat-preservation thermal-insulation wall material with excellent thermal insulation and high strength. The high-performance heat-preservation thermal-insulation wall material has light weight, thermal-insulation effects, high strength and good fireproof performances.
Description
Technical field
The present invention relates to building thermal insulation material and field of engineering technology, be specifically related to a kind of high-performance heat-preserving heat-insulating wall material and preparation method thereof.
Background technology
Materials for wall is maximum, the indispensable material of construction of building field consumption, and its development has close relationship with the energy, environment.For many years, construction wall generally adopts single-material, as hollow concrete block wall, vacation concrete wall etc.
Because single-material thermal conductivity is comparatively large, can not meet heat insulating requirement, therefore, need often to adopt material and thermal insulation material (as rock wool, mineral wool, polystyrene board etc.) in city according to building energy conservation form combined wall.Combined wall has played the strong point of bi-material well, and body of wall both can not have been made blocked up, again can load-bearing, and heat insulation effect is good again.
Exterior wall internal insulation now Insulation is major way mainly with rock wool or mineral wool and plasterboard compound, glass wool and plasterboard compound, polystyrene foamed plastics and plasterboard compound, aerated plaster plate and body of wall smear adiabatic mortar greatly.But the current performance such as insulating wall material intensity, weather resistance is still far below traditional bearing wall.
The advantages such as the method described in this patent utilizes silica aerogel thermal conductivity low, and fire resistance is good, can utilize slag and flyash, resource utilization degree is high, environment-friendly high-efficiency simultaneously.
Summary of the invention
The object of the invention is to build concrete heat-insulating heat-shielding net on both macro and micro two yardstick, thus develop a kind of high-performance heat-preserving heat-insulating wall material of exploitation and preparation technology thereof, the heat insulation haydite primarily of porous wherein in macro-scale realizes, and heat insulation on micro-scale realizes primarily of micron-sized silica aerogel powder.
Object of the present invention is achieved through the following technical solutions
(this part is revised according to the mode of claim.)
Bottom solid material to add water mixing by following composition and quality proportioning: cement 20 ~ 40 parts, haydite 10 ~ 30 parts, blast-furnace slag 20 ~ 40 parts, 30 ~ 50 parts, flyash, sand coarse aggregate ratio 39% ~ 42%, silica aerogel be dry material 0.2% ~ 0.5%, water reducer volume determines according to degree of mobilization, water-cement ratio is 0.45 ~ 0.5, after abundant stirring, through building, maintenance, final acquisition has good thermal insulation property, high intensity and high performance heat-preserving heat-insulating wall material.
Foregoing method, preferred scheme is that concrete steps are as follows:
With tetraethoxysilance or positive methyl-monosilane or water glass for carbon source, adopt sol-gel method, prepare silica aerogel;
Take the water of certain mass by design proportioning, by heavily taking silica aerogel powder, utilizing dispersion agent it fully to be incorporated in water and also fully stirring obtained slip, adding water reducer, carry out secondary stirring 3 ~ 5min;
Cement, haydite, blast-furnace slag, flyash are put into stirrer dry mixing 3mim ~ 5mim and carried out premix;
The slip that [0011] is obtained slowly adds in [0012], stirs, and process is built, maintenance, final obtained high-performance insulating wall material.
Foregoing method, the preferred label of cement is the Portland cement of P.O42.5R, the high-strength fly-ash haydite of pottery material preferable particle size 5mm ~ 15mm.
Water reducer used is conventional high efficiency water reducing agent, and water-reducing rate is not less than 20%.
For ensureing the necessary performance such as intensity, weather resistance, fire prevention of insulating wall material, the present invention adopts concrete as heat-preserving heat-insulating wall material.
In order to improve concrete heat insulating effect, utilize the porousness of haydite on the one hand, realize heat obstruct to a certain extent, but because haydite yardstick is larger, be generally more than 5mm, heat obstruct can only be carried out on a macroscopic scale, micron-sized silica aerogel is utilized to realize the obstruct of heat on microcosmic on the other hand, silica aerogel has round shape multi-branched nanoporous three network structures of high-permeability, it is the solid-state material that current thermal conductivity is minimum, the sol-gel method adopted by the present invention obtains in a large number, this material be used in the present invention constructing concrete micro-scale heat intercept network, thus significantly improve concrete heat insulating effect.
