Description
Technical field
The invention belongs to the monoblock fire resisting material field that does not contain clay, relating in particular to a kind of is the warming plate of matrix with the ceramic fiber.
Background technology
The ceramic fiber warming plate of prior art, because the restriction of production technique, surface irregularity presents orange peel shape, adds man-hour owing to fiber interweaving, and mechanical process capacity is poor, and general processor is difficult to satisfy.In addition, because goods are production moulding in mould, easily produce the goods geometry deformation during demoulding, though can repair lining, the surface is still uneven.During construction, because the geometrical dimension out of true of goods, the construction back wall is uneven, the construction slit is big, thermal conductivity is high, increase the application quantity of indefinite form material, thereby limited the big area popularization of product, make the fiber function can not get comprehensive embodiment as construction tackiness agent, coating.
Nineteen ninety-five, disclosed Chinese patent application 94102154.8 provided a kind of composite, insulating, light organosilicon wall material, and its major ingredient is: aluminosilicate fiber cotton, perlite, wilkinite, water, asbestos, useless fiber, caustic soda, epoxy glue, stablizer, thickening agents, permeate agent, starch, hydrogen peroxide, starter, cullet silk.Though this material has heat insulation and heat insulation effect, only be suitable for cryogenic material.On March 20th, 2002, disclosed another Chinese patent application 00111348.8 provided a kind of mechanically made ceramic fibre plate, it adopts aluminum silicate fiber, organic bond, inorganic bonding agent and additive to form, and the ratio of aluminum silicate fiber, organic bond, inorganic bonding agent and additive is: 1: 0.05～0.1: 1～1.5: 0.05～0.1.Wherein organic bond is resin, starch and Mierocrystalline cellulose, and inorganic bonding agent is silicon sol and aluminium glue, and additive is alumina powder and clay micro mist.But owing to adopt vacuum forming, the geometrical dimension of finished product still has certain deviation, and heat-insulating property is poor slightly.
Summary of the invention
The purpose of this invention is to provide a kind of ceramic fiber warming plate and its preparation method, the warming plate that especially a kind of geometrical dimension deviation is less, heat-insulating property is good.
Technical scheme of the present invention is: a kind of ceramic fiber warming plate, form by ceramic fiber, inorganic bonding agent, organic bond and additive, it is characterized in that the weight ratio of ceramic fiber, inorganic bonding agent, organic bond and additive is: 60～40: 30～20: 0.5～1.5: 30～20.Ceramic fiber can adopt the alumina-silicate ceramic fibre of different Applicable temperatures; Organic bond is one or more the mixture in polyacrylamide, cationic starch or the carboxymethyl cellulose; Inorganic bonding agent is one or more the mixture in cement, silicon sol, aluminium colloidal sol or the water glass; Additive is one or more the mixture in ground silica, expansion ground silica, swelling perlite powder or the silicon powder.
The preparation method of above-mentioned this ceramic fiber warming plate is to be base material with the ceramic fiber, add inorganic bonding agent, organic bond and additive, carry out abundant slurrying, adopt the mechanical presses method of forming or manual assembly to produce wet base then, drying treatment through 100～150 ℃, remove moisture, impel goods internal junction mixture to carry out gel, sclerosis, reach and to try to achieve hardness.Dried goods utilize that mechanical means is cut, grinding, brill, carry out further deep processing.
The ceramic fiber warming plate after drying because the difference of additive, that warming plate presents is faint yellow, brown or grey, Applicable temperature is extensive, can be used for the backing or the permanent furnace lining of various high, medium and low temperature kilns.
Be the comparison of the present invention and vacuum forming fiberboard below:
| Project | The ceramic fiber warming plate | The vacuum forming fiberboard |
| Length variation mm | 0 +2 | ±3 |
| Width difference mm | 0 ±2 | ±3 |
| Thickness deviation mm | ±0.1 | ±2 |
