Abstract
The invention belongs to inorganic fire resistive material field, especially relates to a fire and irradiation resistive coating material and the preparation method. It is characterized in that the comprised materials and their proportion are as follows: aluminium oxide calcined at high temperature 2- 400 units, zirconium oxide 2- 100 units, chromium oxide 5- 100 untis, clinker 1- 100 units, alta-mud 1- 80 uints, hexametaphosphate 0- 100 units, carboxymethyl cellulose 1- 50 uints, silicon carbide 20- 100 units, iron oxide black 0- 60 units, aluminum hydroxide 0- 100 units, cobalt oxide 0- 50 untis, copper oxide 0- 50 units, brown fused alumina 10 -200 uints, silicasol 0- 100 uints, sodium silicate 0- 400uints, the grain size of each components is not less than 360 order. The coating mateiral is calcinated at high temperature and there is one calcination shell on fiber cotton, and the bearing force of calcination layer and fiber cotton are equal. The coating material employs high- emission material and so it can save energy.
Description
Technical field:
The invention belongs to the inorganic fire proof material field, particularly a kind of high temperature resistant radiation paint and preparation method thereof.
Background technology:
Develop energy, utilization rationally and save energy are important state basic policies of Chinese national economy.And save energy is one of the most simple and effective method that realizes this state basic policy.In the past at the body of heater of industrial furnaces such as the used process furnace of metallurgical, machinery, petrochemical industry, hotblast stove, oil refining furnace, pyrolyzer, used refractory materials is silicon, aluminium refractory brick and unsetting casting material mostly, because refractory fiber cotton has better heat-insulation and heat-preservation effect than refractory brick, thereby has more adopted refractory fiber cotton as furnace lining to the stove that temperature uniformity has higher requirements.But there is following problem in refractory fiber cotton as the body of heater of High-temp. kiln:
1, the mechanical property of cellucotton is poor more than refractory brick and casting material, and hot blast, thermal shock in the High Temperature Furnaces Heating Apparatus make the cellucotton powder of detached, so the work-ing life of cellucotton is shorter.
2, the thermal emissivity rate of cellucotton is lower.
3, because the cellucotton quality is loose, general high-temperature infrared coating is applied on the cellucotton, can cause cellucotton local shedding even integral body to come off.
Summary of the invention
The object of the invention is to propose a kind of cellucotton high temperature heat radiation coating at the blank of cellucotton with high temperature heat radiation coating.This coating forms a sintering shell on cellucotton behind high temperature sintering, this sintering shell is suitable with the cellucotton holding capacity, can be firm be attached to cellucotton, protection cellucotton furnace lining, the work-ing life of prolongation stove.
A kind of high temperature heat radiation coating and preparation method thereof, high temperature heat radiation coating component (by weight) is:
2～400 parts in high-temperature calcination aluminum oxide
Zirconium white 2～100-part
5～100 parts in chromic oxide
1～100 part in grog
1～80 part of wilkinite

0～100 part of silicon sol
0～400 part of water glass
More than each solid constituent granularity be not less than 360 orders.
High temperature heat radiation coating preparation method of the present invention is as follows:
Earlier carboxymethyl cellulose is made gluey fluid, again other solids are mixed adding by proportioning, make thick coating products.
The performance index of this high temperature heat radiation coating are as follows:
Refractoriness: be not less than 1800 ℃
Hemispherical emissivity: 〉=0.9
Unit weight: 1.6～2.4g/cm
3
Linear expansivity: 5.0 * 10
-6～9.7 * 10
-6/ ℃
This high temperature heat radiation coating construction technology is as follows:
1, surface-conditioning.
2, the brushing before can spray water in right amount wetting a little.
3, spraying heat radiation coating.
Coating of the present invention is behind high temperature sintering; on cellucotton, form a sintering shell; this sintering shell is suitable with the cellucotton holding capacity; can be firm be attached to cellucotton; protected the cellucotton furnace lining; prolonged the work-ing life of stove greatly, the while has reached energy-saving effect owing to this coating employing is the high emissivity material.Particularly silicon carbide is carried out the finishing of protectiveness, improved resistance to deterioration, delayed the speed that general high-temperature infrared emissivity of coatings reduces gradually, prolonged the work-ing life of coating.Also because whole body of heater has sprayed heat radiation coating and formed surface radiation, make radiation field more even, thereby heating object is heated evenly simultaneously, improved quality product.
