Description
Technical field
The present invention relates to a kind of base geopolymer binding agent, relate in particular to a kind of base geopolymer binding agent binding agent for preventing fires between every core and door-plate, belong to new material technology field.
Background technology
Fire door refers to and can meet within a certain period of time the door that fire stability, integrity and thermal insulation require, and is located between fire compartment, emergency staircase, vertical shaft.In order to allow fire door play better fire-proof and thermal-insulation effect, generally all in door leaf, fill the nontoxic fire-proof heat-insulating material of human body.The bonding sizing material of current fire door door-plate and door core, a lot of enterprises are still used the organic gel such as polyurethane foam glue, white glue with vinyl, PU glue, but there is the venomous injurant severe overweights such as volatile gas, free formaldehyde in this class organic gel, and the problem such as resistance to elevated temperatures is poor, inflammable.In order to improve the resistance to elevated temperatures of binding agent and to reduce toxic situation, the producer has developed water glass adhesive and has replaced organic gel.Water glass adhesive is by water glass, solidifying agent and media assemblage, after solidifying, have that viscosity is strong, heat-insulating, fire-preventing, do not fire, the advantage such as cheap.But there is the defect of not water-fast and warm change poor stability in water glass itself; water glass assembly glue after solidifying is running into water or under wet environment; very easily dissolve and occur the serious problems such as defeated and dispersed, expansion; cause coming off between bonded, fire-proof product performance degradation, lose due fire prevention and defencive function.In addition the variation of temperature is also very large on the impact of existing water glass assembly glue, and along with temperature raises, the curing speed of water glass assembly glue is accelerated greatly, the situation that easily causes assembly glue to lose efficacy.Therefore, market in urgent need is a kind of with low cost, and adhesive property is good, anti-flaming thermal-insulation performance is good, the matrix material of water-fast humidity.
Geopolymer (Geopolymer) is called for short ground polymers, refer to by geochemistry process or manually imitate the artificial rock of aluminum silicate that geology Synthesis generates, its basic structure is to be polymerized and to be had the three-dimensional netted gelinite of non-crystalline state and quasi-crystalline state feature by silicon-oxy tetrahedron and aluminum-oxygen tetrahedron.Because this gellike material mainly be take silicon-oxy tetrahedron and aluminum-oxygen tetrahedron as main, and similar with the sal composition of clay, there is the similar macromolecular structure of organic polymer simultaneously, the three-dimensional net structure with polymerization, so it has the advantages such as high strength very, good workability, resistance to chemical attack, water-fast heat, high temperature resistant, good endurance.The present invention be take ground polymers synthetic materials technology as basis, invented a kind of water-fast, viscosifying power is strong, with low cost, prevent fires paste binding agent good.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of base geopolymer binding agent, for the bonding between fire door door-plate and door core.
The solution of above-mentioned technical problem is to have adopted following technical measures: a kind of base geopolymer binding agent, is mainly comprised of following weight parts raw material: sodium silicate 95-105 part, slag 15-35 part, calcium carbonate 3-6 part, 8-15 parts of unslaked limes, metakaolin 8-15 part, aluminium triphosphate 0.5-1 part, retardant 0.5-2 part, emulsion 1-2 part;
Described sodium silicate is that solid content is 38%, the commercial sodium water glass that modulus m is 2.0-2.5;
Described slag is fineness 100-600 object blast furnace granulated slag;
Described calcium carbonate is that commercially available fineness is 600-800 object calcium carbonate superfine powder;
Described unslaked lime is fineness 200-400 object commercially available prod, formal name used at school calcium oxide;
Described metakaolin is that fineness 1000 object kaolin raw ores are calcined the powder of 2 hours gained in 800 ℃ of environment;
Described aluminium triphosphate is the white powder crystal of colorless and odorless, is commercially available prod;
Described retardant is a kind of or arbitrary proportion mixture in SODIUM PHOSPHATE, MONOBASIC, sodium hydrogen phosphate, sodium bicarbonate, carbonic acid sodium dihydrogen;
Described emulsion is a kind of or arbitrary proportion mixture in VAE emulsion, benzene emulsion.
Above-mentioned base geopolymer binding agent, by following method, prepared:
(1) proportionally various raw materials are taken, standby;
(2) first sodium silicate is put into stirrer, when stirrer rotating speed reaches 600r/m, add slag, calcium carbonate, unslaked lime, metakaolin, stir;
(3) stirring velocity is adjusted to 800r/m, add successively aluminium triphosphate, retardant and emulsion, and stir and obtain paste binding agent;
(4) by binding agent ageing 12h packing, obtain.
Take the present invention of above-mentioned measure, owing to selecting geopolymer as starting material, possess the macromolecular structure of similar organic polymer and the three-dimensional net structure of polymerization simultaneously, therefore there is the advantages such as high strength, resistance to chemical attack, water-fast, high temperature resistant, weather resistance, the binding agent of preparation also possesses good anti-flaming thermal-insulation effect thus, water tolerance is extremely strong, not water-swelling, and fire-protection rating can reach A level.
The preparation technology that the present invention adopts is different from existing Waterproof gum preparation technology, without adding solidifying agent, without hot-press solidifying, solved in existing fire door assembly glue preparation process the problem of overrunning and condensing because solidifying, because of hot-press solidifying, lift the problems such as cost, contaminate environment.
The present invention has added Industry Waste slag, and this processing that is Industrial Solid Waste provides a kind of effective and feasible method.In addition, what the present invention adopted is ground polymers synthetic technology, production process environmental protection.
After testing, binding agent cohesive strength >=5mPa prepared by the present invention, does not fire, and the moisture absorption that do not absorb water is nontoxic.
