5~25 parts of zinc stearate;
50~100 parts of mortar king;
25~60 parts of industrial calcium zinc powder;
10~15 parts of demoulding powder.
The fireproof heated board that the object of the invention one is realized is using the cement possessing excellent fire protecting performance;Have fireproof heat insulating concurrently The quartz sand of energy;The perlite, foam beads and the Margarita that possess excellent heat-insulating property are husky;The Margarita sand of lifting product intensity, Agstone and Calx;Have rubber powder and the zinc stearate of waterproof and dampproof performance concurrently;The work of improving product crack resistence performance Industry calcium zinc powder;The mortar king of workability arrange in pairs or groups and lift the homogeneous air entraining agent of finished product, improving mortar and separating powder, make guarantor Warm plate has the advantages that lightweight, heat-insulated, sound insulation, insulation, fire prevention, protection against the tide, cracking resistance, anti-hollowing, peel.
The two of the object of the invention are to provide a kind of technique preparing foregoing flameproof warming plate.
The technical scheme realizing the object of the invention two is:A kind of preparation technology of fireproof heated board, its technological process includes:
1)Once stirring fermentation:Load weighted raw material is first put into stirring and evenly mixing in mixing plant, slurry to be mixed is by canescence When being changed into grey black, volumetric expansion bubbling, once stirring fermentation completes;
2)Secondary vibration ferments:Once stirred the mixed slurry after fermentation and sent in oscillating feeder and carry out secondary vibration and send out Ferment, secondary vibration fermentation when slurry volume to be mixed slowly expands, hardness uprises, color change is black completes;
3)Pressing mold:Mixed slurry after secondary vibration is fermented puts into extrusion forming in mould, natural air drying demoulding after 15 hours Obtain fireproof heat insulating board finished product.
The present invention using original creation formula, combine once stirring ferment and secondary fermentation, substantially reduce fermentation, Foamed time, and further improve finished product cracking resistance through secondary vibration fermentation, pressing mold time also more existing skill simultaneously Art is significantly shortened, and because it is with short production cycle, and is integrally formed by raw material mixing, without linked network, protective layer preparation section, Also as this patent be suitable to produce in enormous quantities, its be easy to cutting and can be effective with surface decoration such as ceramic tiles using homogeneity slurry Paste, improve efficiency of construction.
The fireproof heated board that inventive formulation, technique are obtained has advantages below:
(1)Fire protecting performance is excellent, long service life:This product is A1 level fireproof inorganic sheet material, will not be cold because of expanding after overdoing The impact of stress under compression and ftracture, efflorescence, come off.
