Abstract
Composite weight insulation material product is a kind of moulded insulation.It is compound one deck refractory composite layer on the matrix of light-weight thermal insulation material product.This composite bed can be used coated.Once sintered compound, double sintering composite algorithm acquisition.Have that working-surface density is big, high temperature resistant, compressive strength is big, stable chemical performance, characteristics that heat insulation property is strong.
Description
Composite weight insulation material product.
The invention belongs to moulded insulation.
Existing light-weight thermal insulation material product, little (0.4～0.8 gram per centimeter of proportion
3).Little (λ＜0.002 meter of thermal conductivity
2/ time), therefore has good thermal and insulating performance.But it has refractoriness low (＜1650 ℃), not high (＜45 kilograms per centimeter of intensity
2) working temperature low (800～1000 ℃), shortcomings such as stability at elevated temperature difference have limited its use range and Practical Performance.Existing fire resistive material product has than great (＞1.8 gram per centimeters
3) fire-resistant height (＞1730 ℃), working temperature height (＞1200 ℃), compressive strength height (＞150 kilograms per centimeter
3), the advantage that stability at elevated temperature is good.But its thermal and insulating performance is very poor.So their range of application is subjected to certain restriction.
The objective of the invention is, get the length of light heat insulating material and refractory materials, mend its weak point.Refractory materials and light heat insulating material goods are combined with each other, make composite weight insulation material product, its surface composite layer has the pyritous performance, and matrix has the performance of heat insulating.
The design of this paper invention is the good composite bed of compound one deck fire performance on the matrix with the good light heat insulation material of thermal and insulating performance.Refractory composite layer can be magnesia by clay matter, high alumina matter, chromium matter, chromium, zirconium matter, carbonization are siliceous etc., and refractory materials is formed with caking agent, additive.Caking agent has fireclay, phosphoric acid salt, silicate, silicon sol, spent pulp liquors etc., and the light thermal-insulation body material can be diatomite, Shi Zhishi, and microballon or other foam lightweight materials are that main body is formed.
The manufacture method of composite weight insulation material product has three kinds, a coated method, two disposable sintered combined methods; The sintered combined method of three secondaries.
No matter the main raw of the sort of method composite bed is similar, press its mixing ratio by weight for example down according to different light materials:
1) aluminium matter: bauxitic clay C0～80%, kaolin 40～20%; Add silicon sol 20～30%, aluminium dihydrogen phosphate 15～10%, methylcellulose gum 30%, water is an amount of.
2) clay matter: kaolin 65～80%, fireclay 15～30%, water glass 2～8%, water is an amount of.
3) high alumina matter: high-alumina fly 56～82%, titanium dioxide 1.2～2%, fireclay 10～15%, water glass 2～6%, water is an amount of.
4) chromium matter: chromite powder 70～85%, fireclay 5～15%, dense lignosulfite 3～6%, water is an amount of.
5) chromium is magnesia: chrome magnesite powder 45～60%, and magnesia 34～45%, fireclay 7～15%, water is an amount of.
6) zirconium matter: zircon powder 55～76%, silicon sol 15～25%, fireclay 7～15%, water is an amount of.
7) carbonization is siliceous: carborundum powder 55～80%, and silicon sol 13～25% fireclays 7～12%, Manganse Dioxide 1.5～2%, water is an amount of.

4. the sintering process by the light thermal-insulation body material carries out sintering.
Three, double sintering composite algorithm.
1. fire the composite bed goods (sheet or piece) that meet thickness and shape need by the technology of general fire proof material brick
2. the composite surface at composite bed goods (sheet or piece) is coated with one deck splicing slurry.
3. will be coated with the composite bed goods (sheet or piece) that glued joint slurry and put into mould, add the lightweight compound, press forming.
4.40 cryodrying below ℃.
5. double sintering.Press light thermal-insulation body material sintering process sintering.
Best implementation method of the present invention is disposable sintered combined method, and technology is simple, and the good cost of performance is low.
Use the manufacture method of the compound disposable baked light-weight thermal insulation fire-resistant supporting plate brick of clay matter as resistance furnace:
1. in following ratio preparation lightweight compound: microballon 60%, fireclay 32%, wood powder 8%, spent pulping liquor 4%, water ratio 21%.Through the mixer thorough mixing, order is stranded to be put more than four hours.
2. prepare the composite bed slurry by following being equipped with, kaolin 70%, fireclay 30% water glass 6%, water is modulated into pasty state in right amount.
3. the lightweight compound is packed in the mould, in 30 kilograms per centimeter
2Forming under the pressure.
4. with hairbrush the composite bed slurry is applied to the position of holding in the palm resistance wire, thickness is not more than 0.8 millimeter, and brushing evenly.
5. at the kiln inner drying that is lower than 40 ℃.
6. dry good blank sintering in agglomerating chamber.Sintering temperature is 1150 ℃, and insulation is more than 6 hours.All sintering time was not less than 60 hours.
7. naturally cool to normal temperature.
