Abstract

The material for the foamed ceramic contains four kinds of inorganic compounds: vulcanic rock which expands when heated and has acid SiO2 as main component, compound comprising oxides of alkali earth metals and carbonate, inorganic alkali metal combinder and foaming promotor containing silicates, and it has also proper amount of water. Through swelling, mixing, grinding, stoving, crushing, forming and sintering, the material is produced into inorganic foamed ceramic, which, other than the features of common ceramic, is light, sound isolated and low in hydroscopicity.

Description

A kind of light foamed ceramic and manufacture method thereof
The present invention relates to a kind of light foamed ceramic and manufacture method thereof.
Generally speaking; the foamed ceramic of mineral-type is organic foamed ceramic of main composition compared with hydrocarbon oxygen; because preferable physical and chemical stability is arranged; for example do not discharge smog or toxicant with high-temp combustion; can be acidproof; alkali; chemical erosions such as organic solvent; advantages such as good weatherability properties; its manufacturing processed is not followed harmful waste water in addition; waste gas or not tractable by product; help the protection of ecotope; so at people's livelihood building materials and Industrial materials (low temperature or high temperature filter material; adiabatic material; fire proofed wood etc.) military even; application such as space, the importance that all has it to be difficult to replace.
The patent of the relevant inorganic foamed pottery of TaiWan, China has:
6911890: add water hardening with volcanic ash, cement and obtain light building material;
76107199: obtain the cloth of coating-type lagging material with inorganic fibre, organic fibre, refractory mortar, interfacial agent etc.;
77101884: the cavity that becomes to interpenetrate with silicon carbide and colloidal state tripoli wedding agent high temperature sintering;
77107793: become the local hole foam that connects with high temperature sintered surfaces such as porcelain cement, glass, clay, dextrin solution, carclazyte bricks;
78106198: the refractory materials that becomes microdilatancy high specific gravity (＞3.0) with aluminum oxide, titanium dioxide, triphane high temperature sintering;
80102112: with clay powders, the coal dust mixed sintering becomes continuous hole foam;
80109036: the filtration dictyosome that becomes continuous hole with aluminum oxide, mullite, organic polymer high temperature sintering;
81100283: make the mold material with low temperature such as aluminum oxide, colloidal sol, particulate refractory body, organic binder bonds;
81109097: the freezing of alumina microsphere and mullite-gel pottery solution composition thing be main make metallurgical with pottery.
The patent of the relevant inorganic foamed pottery of the U.S. has:
3958582: reconcile into mud injection mould with aluminum phosphate, perlite, ceramic fiber water and be shaped hot setting;
3962081: the urethane Sponge is soaked in the ceramic mud of salic, zirconium white, kaolin, wilkinite, gluey pure aluminium silicate, remove that unnecessary mud etc. is handled and drying after high temperature sintering in addition;
4084980: the presoma that can produce the polyurethane foam effect promptly contains isocyanic acid polyalcohols and ceramic powder mixed hardening, and high temperature sintering obtains the foam of hole intercommunication;
4336068:, feed carbonic acid gas and harden with microwave hot-press with perlite, kaolin, trevira, water glass etc.;
4780433 and 4740486: with clay mixed waste (rice-straw ash, wood chip, grass bits etc.) postforming sintering;
4822541: with clay, silica, SODA ASH LIGHT 99.2, SODIUMNITRATE, rhombspar, Wingdale etc. in the stove of continous way cellar for storing things through intensification, sintering, foam, planish, step such as cooling, emphasize to reduce the space intercommunication, and increase the number of independent pore;
4871495: with low-temperature stiffenings such as pure aluminium silicate, aluminium powder, refractory body, interfacial agents, sintering is burnt organism in addition again;
4900698: after shapings such as polyethylene, inorganic oil, aluminium powder, aluminum oxide, Zinic stearas, the inorganic oil high temperature sintering again of rushing;
5082607: alumina powder and the monomer (as vinylbenzene) that can carry out emulsion polymerization are blended in the also polymerization sclerosis that is shaped in the mould, take out sintering then, burn organism;
The above patent of analysis-by-synthesis, foamed ceramic can be with low temperature (below 250 ℃) be shaped i.e. " the cold junction method " of hardening, or burn till with high temperature (more than 700 ℃), that is: " sintering process ", generally speaking, both maximum differences are: the former can be shaped after foaming in long-time again sclerosis, and the latter to be foaming almost carry out simultaneously with thermal sintering, though the former has the remaining last hardened possibility of small molecules, but there is bigger elasticity to adjust hole of foam (interoperability or independence) and shape specification simultaneously more than the latter, so on industrial application, trend towards independently foam of cold junction manufactured hole, and make the hole intercommunication as being applied to the occasion of filter at low temperature with sintering process.
The object of the invention system provides a kind of light foamed ceramic and manufacture method thereof, produces the foamed ceramic that has pure, stable height of matter and tool independence hole concurrently with sintering process.
Light foamed ceramic of the present invention and manufacture method thereof, wherein Tao Ci component and proportioning are respectively:
Component concentration (weight percent %)
1, overheated inflatable, with acidity
Silicon-dioxide is the volcanics 15-30 of main composition
2, alkaline including earth metal type oxide, carbon
The compound 3-10 that hydrochlorate etc. are formed
3, the inorganic bonding agent 45-70 of alkali metal containing class
4, the foamed promoter 4-15 that contains silicates
Will be by all components of said ratio by following manufacture method: be that each component is mixed, in addition an amount of water gets final product through steps such as calcining expansion, batch mixing, grinding, oven dry, pulverizing shaping, sintering then.
Wherein, component 1-4 of the present invention respectively can for:
Component 1: the perlite class of glassiness volcanics, its typical weight consists of SiO 2(70-75%), Al 2O 3(12-15%), combination water (0.5-6%), Na 2O (2-5%), K 2O (2-6%), low volatile (0.5-5%) and small amount of Fe 2O 3, TiO 2, CaO, MgO, perlite class inflatable 4-20 to original volume under 800-1200 ℃ doubly can be divided into obsidian (less than 2%) according to water-content, three kinds of perlite (2-6%) and pitchstones (more than 5%).
Component 2: suitably the person is CaO, MgO, MgCO 3, CaCO 3, CaO, SiO 2, have the heatproof function basically, suppress the influence that foam changes for dramatic temperature.
Component 3: suitably the person is XSiO 2R 2O, wherein X is 2.0-3.0, R is Na or K, and the function of the combination that is shaped is provided basically.
Component 4; Suitably the person is talcum (H 2MS 3Si 4O 12), mica (KAlSiO 4), silica gel (H 2SiO 4, zeolite (Na 2OAl 2O 32SiO 2XH 2O), the function that has the catalysis foaming basically.
The present invention's light foamed ceramic and manufacture method thereof, the detailed reaction mechanism of wherein foaming in the method, sintering, shaping waits to solve, and should involve the pyroreaction of soda acid basically; But the thing that can confirm is removed material and is formed the novelty of making, and still comprises following characteristic:
1, used starting material are the high inorganics of stability, do not contain organism.
2, manufacturing processed does not follow harmful ecological by product to take place.
3, because through pate dure sintering (greater than more than 750 ℃), so fire prevention (more than 800 ℃) function is arranged.
4, be full of the bubble of independent hole, so proportion is 0.1-0.9, also light than water, sound insulation is good.
Foamed ceramic of the present invention is except being applicable to the high building material of construction, since its can forever bubble through the water column go up and material firm, the urgent ball capture mark that can serve as navigation unit by water and flyer, even on the national defence purposes, can be used as the interim landing of seacopter airport, and the interim transfer bridge of engineer troop's built etc.
