Fibre-reinforced cement board or gypsum plank, high-strength cement plate containing lightweight aggregate or gypsum plank, high-strength panel can be made with the thixotropy colloid nanoporous high-strength cement plate that is template or gypsum plank.The present invention preferably with thixotropy colloid for template prepares nanoporous high-strength cement plate or gypsum plank, because it has the advantage of low-density and high-strength low thermal conductivity concurrently simultaneously, the heat-insulating property of light steel-framed composite wall structure, sound insulation value and stress performance can be promoted further.
At this, introducing thixotropy colloid is the mechanism that template prepares nanoporous high-strength cement plate or gypsum plank.
Template is structure directing agent again, plays stay in place formwork effect in containing Microporous Compounds generative process, the generation of induction special construction, extensively adopts organic amine and quaternary ammonium ion as template in the preparation process of zeolite molecular sieve.
Thixotropy colloid, a class has the colloid of thixotroping structure, and it has following characteristics: (1) from having structure to non-structure, or is an isothermal reversible transformation process from the restitution being applied to structure of breaking of structure; (2) this conversion repeatedly of architecture is relevant with the time, and namely the recovery process of structural damage and structure is the function of time.The mechanical strength change of structure is also relevant with the time simultaneously.In fact, thixotropy is the performance of the mutual transfer process of system at a constant temperature between " gel-sol ", for thixotropy colloid, only with mechanical force (jolting etc.), does not need heating that gel just can be made to become colloidal sol; Do not need cooling, only need leave standstill certain hour, become gel from colloidal sol again.
In fact also can be understood as thixotropy colloid is thick colloid between colloidal sol and gel.The elementary particle of colloid is 1 ~ 100nm, and be combined with each other between elementary particle the nanoporous skeleton being formed and have three-dimensional net structure, so simple, thixotropy colloid is exactly the toughness material still under shearing force with nano-porous structure.
When bonding agent and other materials mix with thixotropy colloid, due to colloid toughness and the property sheared, bonding agent and other materials can be evenly dispersed in colloid, until progressively harden thus possessed the original nano-porous structure of thixotropy colloid.The template effect that in the present invention that Here it is, thixotropy colloid plays.
Inorganic colloid thixotropic agent generally has structure that is bar-shaped or sheet, specific area is comparatively large, surface with electric charge, the good suspension of tool, the gel thus there is gumminess and thixotropy of expanding after water suction.Wherein alumina gel also has the characteristics such as easily disperse, water-soluble reversibility, stability.Entringite colloid and silica-alumina colloid are studied less at present, are slightly described here.
Entringite colloid, obtains by following reaction:
Al
2(SO
4)·18H
2O+6Ca(OH)
2 3CaO·Al2O
3·3CaSO
4·32H
2O
CaO·Al2O
3+2CaO+3CaSO
4·2H
2O+30H

Silica-alumina colloid, reacted by Ludox and Alumina gel and generate, its reaction principle is as follows:
SiO2·nH2O+Al2O3·mH
2O
Al2O3·SiO2·(m+n)H2O
Under agitation, the entringite colloid that above-mentioned reaction generates and silica-alumina colloid can not be grown up, become finely ground particles, because the entringite colloid in the aqueous solution and silica-alumina colloid have numerous hydration hydroxyl, thus make the colloid molecule even suspension generated in aqueous phase, become a kind of thick gel material.If be observation main body depending on entringite colloid and silica-alumina colloid, then can think that entringite colloid and silica-alumina colloidal solid are reunited and be piled into loose network structure, inside configuration is filled with moisture.Test shows, entringite colloid and silica-alumina colloid have good stability, can reach the several months be not deposited on bottom, also can not there is recrystallization or be cross-linked and become gel, also have good thixotropy, standing entringite colloid and silica-alumina colloid viscosity after stirring can return to initial level simultaneously.
Silica hydrogel is a kind of rigid gel, does not originally possess thixotropy, and namely the mode of Ludox not by stirring after being converted into Silica hydrogel is transformed into Ludox by Silica hydrogel again.But Silica hydrogel is crisp, under high shear can be broken into the tiny Silica hydrogel of particle, these Silica hydrogel surfaces have highly active hydroxyl and and with electric charge, add that Silica hydrogel inside 90% is all water with upper volume, so can be greatly different in water, when mixing with bonding agent and other materials, also can play the effect of thickening anti-settling, and serving the effect of certain nanoporous template agent.
In general, inorganic thixotropy colloid has following very unique excellent properties.
1) there is good colloidal nano loose structure, can be formed and stable there is thixotropic thickness aqueous phase colloidal substance.
2) very high compatibility is had with all kinds of bonding agent.
3) compare organic template nontoxic, and do not need the later stage to remove.
4) can the high temperature of resistance to 800 DEG C.
In organic thixotropy colloid the thixotropic mechanism of cellulose family be hydrophobic main chain and surrounding water molecules by hydrogen bond association, improve the fluid volume of polymer itself, decrease the space of Particle free activity, thus improve system viscosity.Also can be realized the raising of viscosity by the winding of strand, showing as and have high viscosity at static and low sheraing, is low-viscosity under high shear.This is because when static state or low shearing speed, cellulose molecular chain is in disordered state and makes system present high viscosity; And when high shear rates, molecule is parallel to flow direction and makes ordered arrangement, be easy to mutual slip, so system viscosity declines.
Its thixotroping mechanism of polyacrylic thixotropy colloid is that thixotropic agent is soluble in water, and by the same sex electrostatic repulsion of carboxylic acid ion, strand is stretched to bar-shaped by helical form, thus improves the viscosity of aqueous phase.
Although organic thixotropy colloid non-refractory, consumption is few, low price, can also with inorganic thixotropy colloid with the use of, strengthen the effect of template, and disintegrate does not affect product quality in applied at elevated temperature.
Just based on above characteristic, thixotropy colloid is chosen as the template of nanoporous high-strength cement plate of the present invention or gypsum plank.
The particle diameter major part of the cementitious material such as cement, lime, gypsum is distributed in 3 ~ 45 μm, and colloid will be formed generally need below 100nm, Here it is why when the water/binder ratio of cement is higher, and most of cement granules can not suspend in water, but directly sink to bottom.In other words, we are not by adding water to obtain more low-density high-strength cement plate or gypsum board products.Can not low-density be realized, just cannot realize allowing high-strength cement plate or gypsum plank possess good heat-proof quality.
When adding the cementitious material such as cement in thixotropy colloid, no matter the ratio of cement is how many, all there will not be the phenomenon that cement sinks to the bottom or reunites, cement and other materials added can be evenly dispersed in whole thixotropy colloid simultaneously, and form the high-strength cement plate or gypsum plank material in a large number with similar thixotropy colloidal nano loose structure by the hydration reaction occurred in thixotropy colloid.The aqueous phase of thixotropy colloid inside not only can promote the aquation of cement class bonding agent, the effect of cement curing in water can also be reached simultaneously, thixotropy colloid evenly can improve hydrated cementitious intensity respectively because of, micropore high containing nano particle reactivity, shortens demould time.
Therefore, thixotropy colloid is that the high-strength cement plate of template or gypsum plank have excellent heat-proof quality because of the nano-porous structure of a large amount of similar aerogel material of inside, and has the feature of high strength, lightweight, realizes stressed heat insulation integrated.
In the face of the energy crisis be on the rise, country proposes better requirement to building energy conservation, from early stage energy-conservation 50%, rises to energy-conservation 65%, then to 75% and even 85%, some low-carbon (LC)s building, passive type building continue to bring out.Aerogel material is as the minimum super insulating material of current coefficient of thermal conductivity, the heat-insulating property of assembling body of wall significantly can be promoted with high-strength cement plate or gypsum plank compound, the thickness of significantly reduced body of wall, volume and weight, particularly with after the high-strength cement plate of thixotropy colloidal nano loose structure or gypsum plank compound significantly can promote the efficient energy-saving heat-preservation effect of severe cold area.
Consider that aerogel material is crisp, intensity is lower, and when aeroge and lightgage steel joist compound tense, it is necessary that skin adds a high-strength panel again.
Do decorative layer at high-strength cement plate or gypsum plank external surface, aesthetics and the comfort level of body of wall can be promoted, improve visual experience and live and experience.
