Abstract
The utility model relates to a high-temperature energy-saving xonotlite composite thermal insulation board. The high-temperature energy-saving xonotlite composite thermal insulation board comprises an aluminum-foil sleeve (5) and a two-layer composite foundation thermal insulation board which is arranged in the aluminum-foil sleeve (5), wherein the two-layer composite foundation thermal insulation board is formed by compositing a xonotlite thermal insulation board (1) and a high-temperature thermal insulation board (2) through an adhesive layer (3). On the xonotlite thermal insulation board which is high in strength and low in price is composited with the high-temperature thermal insulation board which is high in application temperature, so that the requirements on temperature, strength and cost performance can be simultaneously met. A sprayed coating plays a role in reflecting the heat. In addition, the thermal insulation board is wrapped by a layer of aluminum foil, so that the high-temperature energy-saving xonotlite composite thermal insulation board has characteristics of water resistance, heat reflection, attractiveness, environmental protection and no dust and also can reduce the logistics cost, the in-situ construction and the packaging garbage.

3, compressive strength is generally below 1.0 MPa, and maximum operation (service) temperature is generally 1000 ℃, is no more than 1050 ℃, now 1100 ~ 1500 yuan/m of market price
3.
Now, quality coal in cement kiln systems is decomposing furnace particularly, requires heat insulation layer should have higher mechanical strength, generally, more than 0.7MPa, has again very high heat resisting temperature, maximum operation (service) temperature up to 1080 ℃ ~ 1100 ℃.Common calcium silicate thermal shield, some mechanical strengths can reach requirement, but its heat resisting temperature does not reach requirement.
On market, cement industry also has lime feldspar plate, extraordinary silicate aluminum board, inorganic nano thermal shield, clayey lightweight thermal baffle, High-Alumina lightweight thermal insulation brick with thermoinsulation material, although their heat resisting temperature can reach the requirement of 1100 ℃, but not that density causes greatly equipment Foundations investment large, as clayey lightweight thermal baffle, High-Alumina lightweight thermal baffle, density is at 600 ~ 1350 kg/m
3between, be exactly that insulation effect is poor, as clayey lightweight thermal baffle, High-Alumina lightweight thermal baffle, thermal conductivity is 0.35 W/ (m K), heat energy loss is large, or price is very high or even too high, if lime feldspar plate, extraordinary silicate aluminum board unit price are at 5000 yuan/m
3above, inorganic nano thermal shield unit price is 30000 yuan/m
3above, be difficult to adopt in a large number in cement industry.

The internal face of aluminium foil cover is directly bonded on the thermal shield outer surface of two-layer compound basis by adhesive glue, and aluminium foil cover is from each face integral coating two-layer compound basis thermal shield; Or, within two-layer compound basis thermal shield is vacuum-packed in aluminium foil cover.
Two-layer compound basis thermal shield two plate faces can also be respectively with one deck coating up and down.
The internal face of aluminium foil cover is bonded on coating outer surface by adhesive glue, and aluminium foil cover is from each face integral coating two-layer compound basis thermal shield; Or, within the two-layer compound basis thermal shield of band coating is vacuum-packed in aluminium foil cover.
Described coating has specific thickness, and definite method of this thickness is: quantity for spray is counted 30 ~ 120g/m by dry powder
2.
Described high-temperature heat insulation plate is lime feldspar plate or extraordinary silicate aluminum board or clayey lightweight thermal baffle or High-Alumina lightweight thermal baffle.
The aluminium foil of described aluminium foil cover is pure aluminum foil, covers paper aluminium foil or cover glass fiber cloth aluminium foil.
Good effect of the present utility model is:
The utility model on the eakleite thermal shield of higher-strength, lower price, the high-temperature heat insulation plate of compound higher serviceability temperature, the simultaneously requirement of satisfied temperature, intensity and cost performance.The coating of spraying has the effect of reflecting heat.In addition, outside is coated one deck aluminium foil, has the effect of waterproof, reflecting heat, environmental protection attractive in appearance, isolated dust, can also reduce the LOGISTICS COST, site operation amount and the packaging waste amount that by water-proofing treating, are increased.
The utility model heatproof is high, intensity is high, compressive strength >=0.7MPa, high-temperature resistant is more than 1100 ℃, can meet well cement kiln decomposing furnace and the needs of other Industrial Stoves to thermoinsulation material intensity and high temperature, what the sheet material overwhelming majority was used simultaneously is the eakleite thermal shield of lower price, high-temperature heat insulation plate proportion seldom, according to overall different-thickness, account for 20% left and right, with regard to lime feldspar plate or extraordinary silicate aluminum board or inorganic nano thermal shield as with regard to high-temperature heat insulation plate, finished product board cost is the highest than the adiabatic plate hight approximately 1/3rd of eakleite, less than half of high-temperature heat insulation plate, cost advantage is obvious.In addition, although high-temperature heat insulation plate is heavier, seldom, high-temperature energy-conservation type eakleite composite heat-insulating shield total body density increases little proportion, on equipment Foundations do not have what impact or impact very little, can not increase equipment Foundations investment or increase seldom.
