Abstract

The invention relates to a rockwool-filled heat-insulating flame-retardant polyvinyl chloride fireproof door and a production method thereof. A door body of the fireproof door is made from, in percent by weight: antimony trioxide Sb2O3 flame retardant added under 5-10%; door plate grille of the fireproof door is filled with rockwool; the surface of the door body of the fireproof door is applied a layer of polyester flame-retardant film; the polyester flame-retardant film is made by: adding polyurethane into dimethyl methyl phosphonate DMMP flame retardant in halogenated phosphates and film blowing. The rockwool-filled heat-insulating flame-retardant polyvinyl chloride fireproof door has good heat-insulating and flame-retardant effects and good fireproof performance, is better than polyvinyl chloride foam doors of the prior art, meets the high requirements on performance and fully meets the fireproof requirements.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a heat-insulating and flame-retardant polyvinyl chloride fire door filled with rock wool and a preparation method thereof. Background technique [0002] So far, traditional PVC foam doors are basically extruded and processed according to the general process. This variety of PVC foam doors adapts to various needs of the market. But in the face of the sudden fire, because of the relentless high temperature of the fire, the PVC foam door was not only deformed and burned, but also gave off a suffocating smell of vinyl chloride, which made people faint and die. This kind of PVC foam door is not resistant to high temperature and fireproof, which has become a major hidden danger of fire. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art, and provide a rock wool-filled heat-insulating and flame-retardant polyvin...
