Description

A kind of stalk composite architectural materials and preparation method thereof
Technical field:
The present invention discloses a kind of stalk composite architectural materials and preparation method thereof, is related to a kind of new straw cement-based and is combined Material and a kind of method of modifying on new maize straw surface, belong to building material technical field.
Background technology:
Maize straw main component is cellulose etc., and cellulose point after aqueous slkali is met when straw skin is incorporated into cement-based material Solve as monose, and carbohydrate contains many-OH functional groups, with free Ga in alkaline medium2+The unstable complex compound of generation, with This simultaneously, hydroxyl easily with hydrone by hydrogen bond association, make cement particle surface formation one layer of solvation moisture film, hinder aquation Process, so that the especially early strength loss of binder materials intensity can be caused serious.In addition, obtained by ESEM Straw skin apparent form is as shown in Figure 1, it can be seen that the outer surface structure of maize straw bast fiber is fine and close and very smooth, " diaphragm " with one layer of bright wax, it may thus be appreciated that maize straw bast in binder materials recombination process with that can produce The insecure phenomenon of certain interfacial adhesion, can equally make binder materials intensity produce decline.Therefore, these factors are to a certain degree On limit application of the stalk in construction material.So being pre-processed to the progress of stalk surface just particularly important.Conventional stalk Surface treatment mode has mechanical damage, chemical treatment, physical treatment etc..Mechanical treatment technique is simple, can allow the thick of stalk surface Rugosity increased, but the destructive power of machinery is stronger, can make the original silicon dioxide skeleton of stalk by broken meeting so as to intensity Significantly decline;Chemical treatment can make the organic material decompositions such as cellulose inside stalk such as sodium hydroxide solution infusion method For glucide dissolution, but 30% or so alkali lye can be remained inside stalk, alkali concn is too high for some engineerings to cause Anti- alkali phenomenon.
Conventional silicate series cement can make its serious slow setting, intensity decline to a great extent with stalk compound tense, work as stalk When volume is 10%, its intensity can drop to below 1MPa, and even stalk is handled by methods such as sodium hydroxide solution immersions, Intensity increase rate also very little, final actual strength is very low can not to be applied to prepare in building material.
The content of the invention:
The invention provides a kind of stalk composite architectural materials, solve that straw cement-based composite material strength is low, anti-freezing property Difference, the technical barrier such as stalk volume is small.
Invention further provides a kind of preparation method of stalk composite architectural materials, a kind of intensity, heat insulating ability are obtained And frost resistance all unusual excellent advanced composite material (ACM)s.
A kind of stalk composite architectural materials of the present invention, it is characterised in that be by the raw material system of following ratio of weight and number Into:
Slag 40-70, flyash 10-30, alkaline constituents 10-20, surface carbonation maize straw 2-20, silicon ash 2-15, calcining Diatomite 2-10, clinker 1-5;Water 25-50.
Described alkaline constituents is made up of 50-70 parts by weight waterglass and 30-50 parts by weight sodium hydroxides.
Calcined diatomite used is made by 5-40min grindings, 200-1000 DEG C of calcining.
Described surface carbonation maize straw is the bast part being carbonized by surface shallow-layer, and length is 1-15mm.
A kind of preparation method of stalk composite architectural materials of the present invention, is comprised the following steps that:
1)The filament for taking maize straw skin to be crushed to 1-20mm is fully dried, and carries out carbonization treatment after drying under vacuum state:Deng Nitrogen protection carbonization 10-30min, 200-350 DEG C of carburizing temperature are pressed, stalk is taken out and seals stand-by up for safekeeping after room temperature is down to;
2)By than weighing alkaline constituents material waterglass and sodium hydroxide, it is mixed evenly stand-by;
3)By than weighing slag, flyash, silicon ash, calcined diatomite, clinker, water and step 1)Surface carbonation stalk, Stirred after mixing;
4)By step 1), step 3)In raw material mixing after carry out mechanical agitation, low-speed running simultaneously adds step 2 slowly)Alkali Component solution mix, stirring at low speed stops 10 ~ 15 seconds after 90 ~ 120 seconds, continues high-speed stirred and is produced after 90 ~ 120 seconds.
The present invention contains stalk surface treatment method --- surface carbonation method, in a certain temperature conditions vacuum carburization Regular hour effectively can volatilize away the organic matter on stalk surface, the straw skin surface of otherwise smooth is showed bumps Uneven lamination stratiform, as shown in Fig. 2 scanning electron microscope (SEM) photographs, so as to increase the cohesive force between stalk and cement matrix.Together When stalk fixed carbon after surface carbonation and silica content increase, carbohydrate etc. can extract material reduce, so The material of heat evolution velocity is delayed to reduce, so that smaller to the intensity effect of cement matrix.
In order that straw cement-based composite has higher intensity and frost resistance, to be prepared using the composite The construction materials such as the right straw building block of excellent performance, stalk wallboard, and in the present invention using a kind of intensity it is high, condense fast through silicon Ash, calcined diatomite are modified alkali-activated slag-fine coal celadon novel gelled material and compound, the of the invention NEW TYPE OF COMPOSITE of stalk The early stage of material and increasing substantially for later strength can dramatically increase the anti-freezing property of composite.
While intensity and frost resistance of the present invention obtain improving, because the volume of stalk is big, its guarantor is greatly improved Warm nature energy, so the novel straw composite of the present invention is a kind of ideal material with many-sided premium properties,
The positive effect of the present invention is:There is provided new composite architectural materials and preparation method thereof, contain a kind of new Stalk surface treatment method-surface carbonation method, can effectively improve stalk surface nature so as to solving stalk and cement base The problem of material is glued difficult.What novel straw composite was not only selected on composition in composition simultaneously is all aboundresources and honest and clean The environmental type resource of valency, and resistance to compression, anti-folding, frost resistance can be obtained all and heat-insulating property is all very excellent new Composite.
