Description
Technical field
The invention belongs to the preparation of inorganic-organic composite material class, the preparation method of particularly a kind of inorganic silicon-aluminum silicate polymer and organic macromolecule composite gelled material.
Background technology
China is an energy big country based on coal resource, and the flyash annual emissions that is produced by fire coal reaches 200,000,000 tons at present; Simultaneously, China also is a big steel country, by each about 100,000,000 tons in the slag of the annual discharging of Steel Plant and slag; About more than 1,000 ten thousand tons by the phosphorus slag that refines the annual discharging of yellow phosphorus.The long-term placement of these waste residues not only takies a large amount of good farmlands, destroys ecological; And expose to the sun and rain for a long time meeting polluted underground water source and rivers and lakes, cause serious environmental to pollute, with its starting material of inorganic aluminosilicate polymer gelling material as the preparation near zero release are one of main paties of industrial solid castoff recycling, to alleviate the energy, environment, immense pressure that resource was faced.For the recycling economy of industries such as coal in China, iron and steel, sustainable development of resource is very great to building " resource-conserving, friendly environment society " meaning.
By natural mineral (kaolin, volcanic ash) and aluminosilicate industrial solid castoff (flyash, coal gangue, slag, slag, phosphorus slag etc.) under the effect of alkali-activator, the fracture of siloxane bond and alumina key takes place, by polycondensation, form the inorganic polymer gel material of the three-dimensional net structure of silicon-oxy tetrahedron and aluminum-oxygen tetrahedron composition again.J.Davidovits has proposed the new ideas of " Geopolymer " in the United States Patent (USP) (USPatent4,509,985) of application in 1985.Different investigators are referred to as " alkali excites gelling material ", " geopolymer ", " soil polyalcohol ", " mineral polymer " etc., but all never ipsilateral reflected the essence of the three-dimensional net structure that the silicon-oxy tetrahedron of its inorganic aluminosilicate polymer and aluminum-oxygen tetrahedron are formed.Alkali excites theoretical development to experience quite very long period, nineteen fifties, the Glukhovsky of USSR (Union of Soviet Socialist Republics) has proposed the alkali activating mechanism of inorganic aluminium silicate mineral, and he thinks the aluminosilicate presoma under the effect of alkali and water, is partly dissolved to generate aluminate and silicate; Subsequently, being in the aluminate of dissolved state and silicate intermolecular dehydration reaction takes place generates inorganic polymer.To the 1980s, the Davidovits of France has proposed " polycondensation " mechanism that alkali excites geopolymer, this theory is thought: (1) is under the effect of alkali-activator, (the covalent linkage fracture Si-O-Al-O-), aquation generates positive aluminosilicate (orthosialate) ion to the silica alumina.(2) positive aluminosilicate (orthosialate) ion is under the effect of alkali-activator, and further polycondensation becomes the network structure of the inorganic polymer of poly-aluminosilicate.Inorganic polymer gel material is in the development process of two more than ten years, by the reaction that initial needs provide certain curing temperature (60-1800C) or steam curing process condition to take place, just develop at normal temperatures the technological process that can prepare by the alkali provocative reaction up till now.In addition, the kind of inorganic polymer presoma is expansion to some extent also, can adopt some natural clay minerals, as: kaolin and volcanic ash; The depleted industrial residue, as: slag, flyash, silicon ash etc.For the aluminium silicate mineral of high calcium content, by alkali-activator excite live after, the calcic component mainly generates Calucium Silicate powder class hydrated product, the aluminium silicon components mainly generates geopolymer.For the aluminium silicate mineral of low ca content, after exciting by alkali-activator, only generate geopolymer.
Inorganic polymer gel material is made up of the three-dimensional network body structure of silica alumina covalent bonds.Its preparation process does not need high-temperature calcination, and does not almost have NO in the generative process
xAnd SO
2Produce CO
2Quantity discharged also very low, whole process of preparation energy-saving and emission-reduction, environmental protection.This material of preparation have ultimate compression strength height, antiacid caustic corrosion, high temperature resistant, solidify characteristics such as nuke rubbish and poisonous and harmful waste material, be expected to become following extraordinary hydraulicity gelling material material.Yet folding strength is poor, fragility is big, and defectives such as dry easily shrinkage cracking are restricted the large-scale promotion application of this material.
Up to now, more than surplus the patent of invention in relevant this field has 150.But patent or blank about inorganic aluminosilicate polymer and organic macromolecule composite gelled material.
Summary of the invention
Fragility at existing geology polymer material is big, the defective of poor toughness, inscribe between the environmental pollution that is caused for scale utilization and the placement that solves industrial solid castoff, the objective of the invention is to, provide a kind of with the industrial solid castoff phosphorus slag, slag is a main raw material, with organic polymer as the inorganic aluminosilicate polymer of structure modifier and the preparation method of organic macromolecule composite gelled material.
In order to realize above-mentioned task, the present invention takes following technical solution:
The preparation method of a kind of inorganic aluminosilicate polymer and organic macromolecule composite gelled material, it is characterized in that, this method utilization can provide the phosphorus slag or the slag of inorganic aluminosilicate composition, with styrene/acrylic methyl terpolymer emulsion, under the effect of exciting agent water glass, generate phosphorus slag or inorganic aluminosilicate polymer of slag and organic macromolecule composite gelled material; Wherein, the consumption of styrene/acrylic methyl terpolymer emulsion is 5%～25% of phosphorus slag or a slag weight, and the consumption of alkali-activator water glass is 13% of phosphorus slag or a slag weight.
The preparation method of inorganic aluminosilicate polymer of the present invention and organic macromolecule composite gelled material, the technique effect that brings is:
(1) can scale utilize industrial solid castoff to prepare inorganic aluminosilicate polymer and organic macromolecule composite gelled material, waste utilization rate height helps the solid waste resource recovery utilization, improves environment, economizes on resources.
(2) adopt the normal temperature prepared technology that need not to heat, preparation process three-waste free discharge, save energy, preparation process greenization, environmental friendliness.
(3) adopt organic polymer to inorganic aluminosilicate polymer modification, form new inorganic-organic interspersed three-dimensional net structure, improved the microtexture of inorganic polymer, the high breaking strength of this composite gelled material 28d is 2.08 times of inorganic aluminosilicate polymer; The dry shrinkage that the inorganic polymer gel material of solution trade waste preparation exists is big, the key problem in technology problem of long-term folding strength retraction and poor toughness.
Novelty of the present invention has been to propose organic polymer inorganic polymer gel material has been carried out composite modified novel method.Organic polymer can be filled in inorganic polymer particulate gap when low levels, reduce its hole porosity.And when high-content, the successive organic high molecular layer can form inierpeneirating network structure with inorganic polymer gel material Si-O-Al network, prevents that inorganic polymer is communicated with the appearance of crackle; It is big to improve the inorganic polymer gel material dry shrinkage, and folding strength is low, the deficiency of poor toughness.
