Abstract

The invention relates to a polyurethane embossment fireproof door. The polyurethane embossment fireproof door comprises a door leaf and a door frame; the door leaf is provided with a polyurethane embossment; the polyurethane embossment is formed by following components of polyether polyol, 0.15 to 0.5 part of 1,8-Diazabicyclo(5.4.0)undec-7-ene, 0.1 to 0.12 part of pentamethyldiethylenetriamine, 0.1 to 0.12 part of tetramethylethylenediamine, 8 to 12 parts of tris phosphate, 8 to 9 parts of melamine, 6 to 8 parts of microencapsulated red phosphorus flame retardants, 1.5 to 1.8 parts of silicone oil, 0.2 to 0.4 part of water and 115 to 125 parts of polymeric phenyl methane-diisocyanate. The invention also provides a production method of the polyurethane embossment fireproof door. The production method comprises the following steps of step a, mold pretreatment; step b, embossment production; step c, after-treatment. The polyurethane embossment fireproof door is good in fireproof performance and excellent in sound insulation effect and the production process is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of home furnishing, in particular to a polyurethane embossed fireproof door and a production process thereof. Background technique [0002] With the continuous development of society, the living standards of modern people are also constantly improving, and they have higher requirements for their own living conditions. People are also paying more and more attention to safety. In the field of home furnishing, for the sake of aesthetics, people mostly install wooden doors and glass doors indoors, and relatively few fire doors are installed indoors. But existing wooden door, can burn, has certain potential safety hazard. Contents of the invention [0003] In order to solve the above problems, the present invention provides a polyurethane embossed fire door with good fireproof performance and sound insulation effect, and the invention also provides a production process of the polyurethane embossed fire door. [0004] I...
