Abstract
The present invention relates to a kind of is the high-temperature heat insulation heat insulating material of raw material with inorganic salt, and it consists of the low calcium-aluminate cement of 70～50% high-qualitys, 30～50% sepiolites, and water is made tackiness agent.Use heat-insulation and heat-preservation material of the present invention, its structural member for building has and does not produce slit, intensity height, high temperature resistant high-performances such as (1700 ℃ of naked lights).
Production technique of the present invention is simple, with low cost, easy construction, and it can be widely used in fields such as metallurgical machinery, electronics, petrochemical complex, building, thermal meter, at military industry field important use value is arranged also.
Description
The present invention relates to a kind of high-temperature heat insulation heat insulating material that inorganic salt are formed that contains.
Industrial used heat-insulation and heat-preservation material category is various both at home and abroad at present, and its performance is not very good, and as diatomite brick, though thermal conductivity is very low, intensity is not high, and use temperature has only 700 ℃; The aluminosilicate property fire-resistant fiber knit blanket, 1370 ℃ of use temperatures; Blended fibre products use 1300～1500 ℃ of working temperatures, but their intensity is all very low; Aluminum oxide foam light cinder brick; working temperature＜1500 ℃; light silicious brick＜1550 ℃; all produce many slits when using them to build kiln by laying bricks or stones; thermosteresis is big; and the worker laboring environment is poor; what use temperature was the highest will calculate the carbon felt; but it must could use in reducing atmosphere or under the gas shield condition, and this just is subjected to great limitation in the use, is not difficult to find out thus; existing heat-insulation and heat-preservation material; their performance can not satisfy industrial to heat-insulation and heat-preservation material technology performance demands far away, and produces these heat-insulation and heat-preservation material technology complexity, and is expensive big; as the fire-resistant fiber knit blanket production line of China from the aluminosilicate property of U.S. CE company introduction; only one of facility investment is just paid 2,800,000 dollars, the investment cost height, and also construction process is too loaded down with trivial details.For a long time, people are seeking a kind of ideal heat-insulation and heat-preservation material for energy-conservation and improve working conditions always.
The objective of the invention is to overcome the deficiency that prior art exists, proposes a kind of can be high temperature resistant, have the heat-insulation and heat-preservation material of higher-strength, specifically technical scheme is as follows:
1, the heat-insulation and heat-preservation material is formed:
High-quality is hanged down calcium-aluminate cement 70～50%
Sepiolite 30～50%
Water is an amount of.
2, process for producing flow process
Ore dressing pretreatment → batching → stirring → moulding → maintenance (natural air drying or drying baker drying) → finished product.
Batch mixes is even according to the above ratio with the low calcium-aluminate cement of high-quality after processing is given in ore dressing for sepiolite, add water and stir into muddy, with its structural member for building or pour into mould molding, maintenance is 1～3 day then, keep structural member for building or demoulding component surface humidity, make its natural air drying or its curing can be used in the drying baker drying.
Heat-insulation and heat-preservation material of the present invention uses on main equipment, as electric furnace top (whole electric furnace top) working face, can add a certain amount of aggregate, if be used as the heat-insulation and heat-preservation material merely, use temperature is 1700 ℃ just need not add aggregate.
The sepiolite that the present invention selects for use is a kind of white, the high fibrous magnesium silicate clay mineral that light weight can be bubbled through the water column, and its chemical molecular formula is Mg8[Si
12O
30] (OH)
412H
2O.It has extremely strong adsorptivity.When it and low calcium-aluminate cement uniform mixing, after adding water and stirring, through hydration reaction, the crystalline structure of its generation is needle-like and tabular, and they can be interweaved into skeleton, thereby make heat-insulation and heat-preservation material of the present invention have high strength.
The present invention compares with existing various types of heat-insulation and heat-preservation materials has following feature:
(1) use temperature height, 1700 ℃ of anti-naked lights.(2) its intensity all is higher than existing lagging material when normal temperature and high temperature.(3) thermal conductivity is low, and thermal capacitance is little.(4) use heat-insulation and heat-preservation material structural member for building of the present invention, do not produce the slit, reduce thermosteresis greatly.(5) Heat stability is good, cold-resistant thermal shocking is strong, has the performance of opposing physics, chemistry, mechanical effect.(6) in light weight, good toughness.(7) insulation, adiabatic, sound-proofing properties is all fine.(8) preparation, easy to use is particularly at construction inconvenient environment and position.
The present invention prepares that production technique is very simple, with low cost, easy construction, its various superior performances in addition, be other heat-insulation and heat-preservation materials can not compare.It can be widely used in fields such as metallurgy, machinery, electronics, petrochemical complex, building, thermal meter.In war industry,, will have more unique use value as in tank, warship, field of aerospace.
Embodiment:
With the fastening plug of metal die processing and fabricating quick temperature measurement rifle rifle head, foraminous cone in the middle of this member system, 1800 ℃ of working temperatures by proportioning provided by the invention, take by weighing 32 kilograms of the low calcium-aluminate cement of 18 kilograms of sepiolites and high-quality, it is mixed, add water and stir into muddy, pour into place two or three minutes in the mould after, the demoulding was put into water after tens hours, make its seasoning, can use after 2 hours.With this fastening plug quick temperature measurement rifle rifle head of packing into, its front end to be inserted in 1800 ℃ of electric furnaces (furnace inner environment temperature), this fastening size of shape beyond the Great Wall can remain unchanged.
Claims (1)
- A kind of high-temperature heat insulation heat insulating material of forming by inorganic salt, it is characterized in that lagging material (by weight), 30～50% sepiolites, the low calcium-aluminate cement of 70～50% high-qualitys, sepiolite is after ore dressing pretreatment, with the low calcium-aluminate cement ingredient of high-quality, add the water stirring pulping, then, structural member for building or pour into mould molding, maintenance (natural air drying or drying baker) 1～3 day.
