Abstract

The invention belongs to the technical field of door and window materials and provides a fireproof door core veneer material with an excellent soundproof effect and a preparation method thereof. The fireproof door core veneer material is prepared from the following raw materials in parts by weight: magnesium oxide, magnesite clinker, silicon carbide, rare earth oxide, polypropylene fiber, mullite, titanium dioxide, fire retardant, surfactant, polyborosilazane, binding agent and soundproof filler. The soundproof filler is added into the formula of the material; the soundproof filler is mainly prepared from hollow glass beads coated with polybutadiene rubber; the soundproof effect of the hollow glass beads is enhanced; after the soundproof filler is filled into the fireproof door core veneer material, the soundproof effect thereof can be promoted; besides, the magnesite clinker, silicon carbide and rare earth oxide in the formula can promote the high temperature resistance and fire resistance of the material.

Description

technical field [0001] The invention belongs to the technical field of door and window materials, and in particular relates to a fireproof door core board material with good sound insulation effect and a preparation method thereof. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. Fire door core board is the filling material in steel fire doors, anti-theft doors, entrance doors and craft doors. The performance of fire doors depends largely on the performance of the core board. At present, the core board of fire doors is mainly made of expanded perlite as the main raw material, mixed with a certain proportion of inorganic high binder and chemical additives, and processed through a whole set of procedures. The prepared fire door has low fire rating and poor sound insulation effect, and cannot meet the requirements of modern fire protection. [000...
