Description
Technical field
The present invention relates to a kind of thermal insulation material and its developments, more particularly to a kind of to be protected for equipment, duct fire type rare earth
Adiabator and its method of production, belong to building material field.
Background technology
Although the building energy conservation and insulation of equipment material in China have prodigious development in recent years, from material performance itself and
All there is undesirable place in use scope.
The thermal insulation material for being currently used for building mainly has two major classes：Organic heat-insulating and inorganic heat preservation.In organic insulation material
Using being more widely EPS sheet and XPS plate, but its combustion rating is low, poor fire, non-refractory, to wall boundary layer and
Binding material is more demanding, is susceptible to hollowing, large area obscission, there is some potential safety problems during one's term of military service；As
The kervit microbead insulated sand slurry that inorganic heat insulation material uses, its shortcoming is that construction technology is cumbersome, pole big by such environmental effects
Easily there is hollowing cracking phenomena, surface need to do anti-cracking waterproof processing, and the integral heat insulation of material is by production and site operation shadow
Sound is larger, and heat insulation effect needs to improve, and particularly thorny between lightweight and intensity, thermal technology's property is poor.
Current building thermal insulation material in the construction process, in order to protect thermal insulation material, is required for being plastered, crack-resistant layer
Construction, increase cost and difficulty of construction, and engineering special-shaped for some, under particular surroundings is difficult to reach thermal requirements.
Invention content
It is an object of the invention to be directed to defect existing for above-mentioned thermal insulation material, and develop a kind of containing rare earth catalyst
The high-efficiency insulated fire-type material of agent, be used in the various equipment such as electric power, chemical industry, metallurgy, mechanical processing, pharmacy, boiler, heat supply network and
Pipeline is difficult to competent special-shaped equipment and pipeline such as ball, tank, valve, elbow and reducer pipe especially suitable for Conventional insulation
Deng heat insulation effect is excellent, and construction is simple is convenient.
Technical solution is used by realizing above-mentioned purpose of the present invention：
The mass parts of a kind of fire-type rare earth heat-insulating material, including following component, each component and each component are：White lime
8~15 parts, 4~8 parts of flyash, 3~5 parts of alumina silicate fibre, 18~22 parts of rock wool, 5~8 parts of glass bead, bentonite 9~12

0.5~0.7 part of ylmethyl cellulose ether, 2~6 parts of polyacrylamide, 0.05~0.1 part of antifoaming agent；The rare earth addition
For cerium oxide.
The white lime is calcium hydroxide, and CaO+MgO contents are not more than not less than the rate that tails over of 65%, 0.9mm sieves
0.2%.
The alumina silicate fibre is containing white type, fibre length 5mm, 1350 DEG C of operating temperature.
The bulk density of the glass bead is 120g/L, rate of closed hole >=80%.
The calcium carbonate is calcite in powder, the mesh of fineness >=200.
The bleeding agent is succinic acid alkyl ester sulfonate sodium.
Compared with prior art, the present invention has the following advantages：Simple production process of the present invention, product diversification (paste
Type, proximate matter coiled material type, dry powder-shaped type).Therefore the present invention can meet various special-shaped equipment and pipeline (such as ball, tank, valve, elbow
And reducer pipe) construction requirement, compensate for the limitation that heat preservation plate material uses at the scene.It is also possible to be made
Paste mixture, scene are not required to again dispensing stirring, ensure that the stabilization of product workability and heat-insulating property, site operation work
Skill is simple and convenient, and required equipment is few, can prepare suitable product according to different engineering-environments, efficiently solve heat insulating work
In various problems, such as thermal coefficient height, fire-protection rating is low, and construction is complicated, of high cost etc..
