Abstract
The invention discloses a forming method of a fireproof safety door, which is carried out according to the following steps: (1) firstly putting a door leaf of the fireproof safety door on a fixed plate and fixing a hinge side of the door leaf on the fixed plate; (2) uniformly stirring fillers of the fireproof safety door in a stirrer, pouring the fillers into a door plate of the fireproof safety door according to the size of the door body and carrying out prepressing on a cold pressing machine in a compression ratio of (9 to 10):5, wherein after prepressing, the thickness of a pearlite fireproof door core is consistent with that of an inner door leaf; (3) coating a polyurethane adhesive in an outer door plate of the fireproof door and then covering the outer door plate on the filled inner door plate; and (4) in the hot pressing process, maintaining the temperature of the pearlite fireproof door between 100 and 110 DEG C, maintaining the hot pressing time for 30 minutes, putting the pearlite fireproof door in an oven to bake and naturally cooling the fireproof door after the fireproof door is discharged from the oven. The forming method makes the fillers of the fireproof safety door directly formed in the door plate by improving the fillers of the fireproof door so as to improve the overall efficiency of production of the fireproof door and improve the overall intensity of the fireproof door.
Description
Technical field
The present invention relates to fireproof safety door, specifically belong to a kind of forming method of fireproof safety door.
Background technology
In the manufacturing process of present fireproof safety door; All be directly to be placed in the fireproof door plate with the perlite production board; Because the restriction of pearlite slab mould, so sized is not easy change, and a door body size is to make according to requirement of client; Both can't unify on cooperating, and making requires a great deal of time is cutting on the pearlite slab.Use pearlite slab to fill door-plate, need make pearlite slab in advance, and through hyperthermia drying, this is for the integral manufacturing of door body, and pearlite slab is production process independently.On the other hand, the surface produced broken end and dust because of weathering after pearlite slab was placed a period of time, one came contaminated environment, influenced workers'health; Two, the difficulty that is connected of pearlite slab and door body when having increased the door body and filling makes pearlite slab and door body bonding difficulty, generation fall slag, come unstuck even problem such as sheet material fracture.
Summary of the invention
The present invention is for fear of above-mentioned existing in prior technology weak point; A kind of fireproof safety door inserts and integral forming method are provided; Through improvement to the labeled door inserts; Make the inserts straight forming in door-plate in the fireproof safety door, with the whole efficiency that improves labeled door production, the bulk strength that improves labeled door.
Technical scheme of the present invention is following:
1, a kind of forming method of fireproof safety door, carry out according to following steps:
1), at first the door leaf with fireproof safety door is positioned on the fixed head, the door leaf hinge edge is fixed on the fixed head;
2), the inserts of fireproof safety door stirs in mixer; Wherein the glue temperature of silicate of soda, magnesia, glass-cermic powder configuration remains on 23～26 degree; Maximum temperature can not surpass 30 degree; Inserts is poured in the door-plate of fireproof safety door according to door body size, and compression ratio is in (9～10): 5 ratio is carried out precompressed in the cold pressing machine, and back perlite fireproof door core and interior door leaf consistency of thickness are closed in precompressed;
3), coat urethane adhesives in the external door panel of labeled door, lid places on the internal hilar plate after filling;
4), perlite fireproof door temperature when hot pressing remains between 100～110 ℃, the hot pressing time is 30min, welds the door-plate junction afterwards; Being positioned over baking oven toasts; Temperature remains on 220～230 ℃, and stoving time is 35～40min, goes out cooling naturally behind the baking oven.
Beneficial effect of the present invention is following:
1, the present invention adopts direct completion method, and inserts directly bonds with a door body, and the bulk strength of door body is significantly improved, and can prevent effectively that door leaf from peeling off because of inserts and door-plate that dust too much causes.Integral-filled processing mode has greatly improved whole work efficiency.
2, the direct mode of filling of the present invention can the most effectively be avoided the waste of inserts, simultaneously, the phenomenon of door leaf hollow can not occur.
3, thereby the present invention can pass through the overall weight of the compression ratio control gate body of control inserts,, helps product quality is carried out digital management as weighing a qualified standard of door body with this.
Fireproof safety door through the forming method of fireproof safety door of the present invention is supported through check each item performance indications is:
Through pressing GB/T202852006 " classification of material producing smoke toxicity risk " check, material producing smoke toxicity is ZA
1Level;
Through pressing GB 8624-2006 " constructional materials and the classification of product burns performance " check, combustibility is the A level.
Through press GB 12955-2008 " labeled door " national standard detection, fire endurance >=90 minute, and when fire-resistant experiment proceeds to 54 minutes, lost integrity not, refractory temperature is up to 1200 ℃, and fire integrity and fire insulation reach compound national standard.
The specific embodiment
1, a kind of forming method of fireproof safety door, carry out according to following steps:
1), at first the door leaf with fireproof safety door is positioned on the fixed head, the door leaf hinge edge is fixed on the fixed head;
2), the inserts of fireproof safety door stirs in mixer; Wherein the glue temperature of silicate of soda, magnesia, glass-cermic powder configuration remains on 23～26 degree; Maximum temperature can not surpass 30 degree; Inserts is poured in the door-plate of fireproof safety door according to door body size, and compression ratio is in (9～10): 5 ratio is carried out precompressed in the cold pressing machine, and back perlite fireproof door core and interior door leaf consistency of thickness are closed in precompressed;
3), coat urethane adhesives in the external door panel of labeled door, lid places on the internal hilar plate after filling; 4), perlite fireproof door temperature when hot pressing remains between 100～110 ℃, the hot pressing time is 30min, welds the door-plate junction afterwards; Being positioned over baking oven toasts; Temperature remains on 220～230 ℃, and stoving time is 35～40min, goes out cooling naturally behind the baking oven.
