Abstract
The present invention relates to a composite heat insulation silicate sectional material which belongs to heat insulation materials for buildings, etc. The present invention is a fibrous reticular elastic material rich in sealed micropores, and has the offwhite appearance and the density between 220 and 250 kg/m<3>. The present invention is composed of serpentine asbestos, alumina-silicate ceramic fiber, dioctyl succinate sulfonate, sepiolite, expanded perlite and water, is manufactured by processes such as heat preservation soaking, agitation pulping and cast drying, is widely used for heat preservation and cold preservation engineering with the medium temperature between-40 and 700 DEG C, such as equipment, pipelines, kilns, buildings, cold storage, freezing (boxes) vehicles, etc., and has the characteristics of good performance, convenient operation, economy and practicality.
Description
The invention belongs to used thermal insulation material and production methods thereof such as equipment, buildings.
Immediate with the present invention in the existing insulation cold insulation material is that application number is that 87101962(1988 is open March 30) patent application disclosed " composite silicate heat insulation material ".This lagging material is with its superior performance, and good energy-saving effect has been brought into play in widespread use in Industry Branch.Existing nearly this lagging material of various schools of thinkers plant produced in the existing whole nation.But, because this lagging material is pasty state, take the mode of brushing layer by layer, construction to need under heated condition, treat the priming paint moisture evaporation during application, can the brushing last layer after the drying.Medium temperature is not high, ambient moisture is bigger if run into, and then the engineering time will be very long.For the equipment that does not have heating condition, buildings, freezer etc., just can not use at all.
The purpose of this invention is to provide a kind of high-performance that can keep composite silicate heat insulation material, again a kind of novel thermal insulation material that can under heating or the condition that does not heat, can both use.
Theme of the present invention is not found identical with product component of the present invention or proximate public technology through the Chongqing branch update search of Chinese science and technology Institute of Social Science Information.
Product of the present invention is the fibrous web-like resilient material that is rich in closed porosity that is made of the multiple light body non-metallic minerals that contains silicate, appearance off-white, density 220～250kg/m
3Its component and content (weight percent) are: chrysotile 15.15～20.00, alumina-silicate ceramic fibre 3.79～10.00, pearlstone 7.58～13.33, sepiolite 2.27～4.67, dioctyl succinate acid sodium 2.27～4.67, surplus are water.
The production method of product of the present invention is: make the composition silicate paste-like material earlier, make section bar again.Raw material and the consumption (weight percent) of producing this product are: chrysotile 3.71～4.62, alumina-silicate ceramic fibre 0.92～2.31, pearlstone 1.85～3.08, sepiolite 0.55～1.08, dioctyl sodium sulfosuccinate 0.55～1.08, surplus are water.Production stage is: (one) raw material is handled: chrysotile, the alumina-silicate ceramic fibre impurity elimination is loosened, and sepiolite is pulverized below 2 millimeters; (2) by prescription metering respectively; (3) soak: 40～60% dioctyl sodium sulfosuccinate of chrysotile, alumina-silicate ceramic fibre, formula ratio is added 40～60% boiling water of Total Water, and insulation was soaked about 24 hours; (4) stir: add the normal-temperature water of the difference of the dioctyl sodium sulfosuccinate of surplus and Total Water and boiling water amount, stir more than 20 minutes,, add sepiolite, pearlstone, stirring 3～5 minutes then to sparing to becoming the foam pasty state; (5) make section bar: pasty state is cast in the mould the dry back demoulding under 100～110 ℃ of temperature.
Product of the present invention detects through Chongqing Building Science Inst., its salient features such as following table: (table is seen the literary composition back)
Product of the present invention and common lagging material salient features relatively see the following form: (table is seen the literary composition back)
Be not difficult to find out that by last table The comprehensive performance of the present invention is better than other lagging materials.Compare with former " composite silicate heat insulation material ", product of the present invention has been done very big change on prescription, make its performance more perfect, and Application Areas enlarges.Simultaneously, because 1 cubic metre of section bar can be equivalent to nearly 2 cubic metres of liquid coating, and price is significantly less than the latter, has reduced transport charge and packing charge again, so use product of the present invention more economical.
Product of the present invention is applicable to insulation cold insulation engineerings such as the equipment of medium temperature in-40～700 ℃ of scopes, pipeline, kiln, freezer, buildings, freezing (Tibetan) case (car).Can be according to different insulation cold insulation object adjustment prescriptions, the section bar product of making different shapes, density and thickness.Only needing during use that this product is wrapped in dielectric surface gets final product.
