Detailed Description

The present invention will be further described with reference to the following examples.

The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model. The conditions in the embodiments can be further adjusted according to specific conditions, and simple modifications of the method of the present invention based on the concept of the present invention are within the scope of the claimed invention.

Referring to fig. 1 and 2, the present invention provides a heat insulation fireproof door, which includes a door frame 1, wherein in order to achieve a fireproof effect, a steel frame 2 is movably installed on the door frame 1 through hinges, a fireproof layer 3 is laid on the inner side of the steel frame 2, and the fireproof layer 3 is made of rock wool material; the rock wool material has the characteristics of non-combustibility, low heat conductivity coefficient, insulation and long service cycle, can effectively prevent a fire from spreading when the fire happens, and avoids the problem that the fire door is warped, bent and the like due to high temperature, so that the fire-proof effect of the fire door is effectively improved.

Referring to fig. 2, in order to achieve the heat insulation effect, a heat insulation layer 4 may be laid on the inner side of the fire-proof layer 3, and the heat insulation layer 4 is made of a glass fiber material; can be when the conflagration breaing out, because extrusion molding polyphenyl material coefficient of heat conductivity is lower, the surface is given as security out for the extrusion molding simultaneously, and inseparable honeycomb has just more effectively prevented heat-conduction, has the characteristic of high thermal resistance, low linear expansion rate to the effectual thermal-insulated effect who prevents fire door that has improved.

Referring to fig. 2 and 4, in order to achieve the noise reduction effect, a sound insulation board 5 may be fixedly connected to the inner side of the heat insulation layer 4, a sound insulation cavity 6 is formed inside the sound insulation board 5, and glass fiber sound absorption cotton 7 is disposed inside the sound insulation cavity 6; can be near when great noise appears, block the noise through acoustic celotex board 5 for the noise passes from the sound-proof chamber 6 in, and glass fiber inhales cotton 7 and makes an uproar once to the noise this moment, thereby the effectual noise reduction who improves soundproof door.

Referring to fig. 2, in order to improve the sound insulation effect, a sound insulation layer 8 may be laid on the inner side of the sound insulation board 5, and the sound insulation layer 8 is made of a wave-crest sound-absorbing sponge material; the inside of sound sponge is inhaled to the crest is full of tiny space and half trompil structure, can absorb the sound wave energy of penetrating in a large number, and sound absorbing effect is better, can carry out the secondary to the noise and fall and make an uproar to the effectual syllable-dividing effect that prevents fire door that has improved.
