Description

A kind of making method of inorganic dolomite magnesia fireproof gel material
Technical field
The invention belongs to relevant fire proof construction decoration material field class, particularly a kind of making method of inorganic dolomite magnesia fireproof gel material.
Background technology
Also magnesium cement or Sorel cement is claimed, since Sorel invention in 1867, the history of existing more than 100 year. it has many performances to be better than portland cement: do not need wet curing, and fire resistance is good, and thermal conductivity is little, and wear resistance is good, and early strength is high, oil resistant, anti-organic solvent, the performance that anti-ordinary salt and sulfide corrode is also fairly good. and therefore, in the world, some countries are successfully applied to light roof, light fire-proof body of wall, cell floor, upholstery, a lot of aspect such as racecourse and tennis court. China, from the SO age, just starts the exploitation of goods, research work, have developed packaging boxboard in succession, top ceiling, partition plate, wood wool board, ventilator trunk, pantile, bathtub, grinding tool, furniture, agricultural dish canopy, grape trellis, cattle and sheep hutch, a lot of goods such as lightweight wall block. but the main source giobertite of the major ingredient MgO of this cement is mainly distributed in Liaoning Province's (accounting for 85%) in China, Shandong Province's (accounting for 10%) and Hebei one with. owing to transporting the difficulty caused, very big inconvenience is brought to its application. and extremely abundant in China as the dolomite resources in one of tago source, the place of production spreads all over each province. at present, the main raw material of national major part all using rhombspar as production active MgO that much magnesite is few, magnesium oxysulfide concrete is fired to rhombspar and has done systematic research, be that preparation of raw material has become the magnesium oxysulfide concrete of excellent property with caustic dolomite, almost also a blank in China. therefore develop dolomite resources, will very high economic benefit and social benefit be had.
At present, China's materials for wall industry is also very backward, in product, about 90% is solid clay brick, about 7,000 hundred million pieces every year, bakes bricks every year and ruins about 100,000 mu, field, a large amount of breaking-up farmland, have a strong impact on agriculture development, therefore, accelerate the paces of materials for wall reform and Building Energy-saving Work, very urgent, country is greatly developing insulation, the novel wall material that heat insulation, fire-proof light is high-strength and operating efficiency is high.
The building block of light dolomite light internal wall, that rhombspar is calcined under rational temperature and time, with the ground dolomite after calcining for main raw material(s), be equipped with blender, and various admixture, material modified, through foaming agent foam, make light fire-proof material, there is investment little, with low cost, the advantages such as high-strength light and wide market.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, a kind of novel high-strength of the present invention, to reach the making method of A level, water-fast, high frost resistance, dolomite magnesia fireproof gel material that energy-saving heat preserving excellent combination property cost is low without chlorion, fire prevention.
The technical solution adopted for the present invention to solve the technical problems is: a kind of making method of inorganic dolomite magnesia fireproof gel material, wherein: by ground dolomite 100-200 weight part, dilute sulphuric acid 20-100 weight part, light calcined magnesia 25-56 weight part, magnesium sulfate 10-15 weight part, supplementary additive water-resisting agent 1-3 weight part, aqueous foaming agent 0.2-18 weight part, catalyzer 2-3 weight part, inhibitor 0.15 weight part, light filler plant fiber powder 20-100 weight part, perlite 6-24 weight part, granules of polystyrene 3-12 weight part and clear water 10-45 weight part, equipment washing aqueous slurry 15-65 weight part forms through manufacturing procedure.
As a further improvement on the present invention: described ground dolomite for being ground to 300-400 order rhombspar magnesium powder, preferably containing calcium carbonate quantity higher than 30% oxidation magnesium amount higher than 20% rhombspar magnesium slag; Light calcined magnesia is active quantities is that 58-65 calcines powder, auxiliary solidification in earlier stage; It is 18% low concentrated acid that sulfuric acid dilutes content for industry; Magnesium sulfate is industrial magnesium sulfate monohydrate or magnesium sulfate heptahydrate, auxiliary solidification in earlier stage; But the broken powder of vegetable fibre sawdust, powdered rice hulls or other plant; Granules of polystyrene is 3-6# particle; Water-resisting agent is silicon class water-proofing powder or poly-methyl silicon class I liquid I water-resisting agent; Aqueous foaming agent is water-based nonionic class composite fluid whipping agent; Catalyzer is orthophosphoric acid salt system, preferred acidic aluminium dihydrogen phosphate powder or liquid type, for accelerating system reactivity; Inhibitor is acid fog inhibitor, prevents diluted acid in the generation of use procedure and initial reaction stage acid mist, is beneficial to environmental protection.; Equipment washing aqueous slurry is by being stayed sulfur acid calcium and magnesia slurry washing lotion with cleaning equipment in this gel product production process, and recycling is without discharge, and energy-conserving and environment-protective are pollution-free.
As a further improvement on the present invention: described manufacturing procedure step adds ground dolomite for being joined by catalyzer in stirred vessel after in 18% dilute sulphuric acid, stirring question response bubble stops after vulcanization acid magnesium to stir, then add light calcined magnesia and stir 1-2 minute, with appropriate equipment washing aqueous slurry and part clear water adjusting viscosity, last foundation production product type adds different light filler, and add whipping agent or through sending out foam that machine is suppressed and stirring blanking after 2 minutes, with Dual-layer or multilayer glass-fiber-fabric and the face roll forming of nonwoven interlining end liner on fire-proof board molding device, about insulation 25-30 degree, the aftershaping demoulding in 18-48 hour.
Compared with prior art, the invention has the beneficial effects as follows: be beneficial to natural ground dolomite in conjunction with light-burning magnesium powder be generated as intensity high, to reach A level, high frost resistance, water-fast, energy-saving heat preserving excellent combination property and the low dolomite magnesia fireproof gel material of cost without chlorion, fire prevention, utilize this gel material by the various building materials product of technological forming, and the recycle of all manufacture course of products rinse water, zero release, energy-conserving and environment-protective.
Embodiment
Application principle of the present invention is as follows:
React under calcium carbonate in ground dolomite and magnesium oxide and sulfuric acid and catalyst action, generate calcium sulfate and fluid sulphuric acid magnesium, after fluid sulphuric acid magnesium and additional sulfuric acid magnesium combine, air-setting magnesium oxysulfide concrete is generated with light-burning magnesium powder reaction, magnesium oxysulfide concrete and calcium sulfate are combined into the fire prevention jello of high strength, and additional sulfuric acid magnesium and light-burning magnesium powder play Curing effect in early stage.According to desired product type, by this jello and the different matched combined of material such as light filler, water-resisting agent and whipping agent, by the dissimilar fire proof construction building material product of technological forming.
