Description
technical field [0001] The present invention mainly relates to fireproof fillers. Background technique [0002] At present, in the production process of fire safety doors, perlite finished boards are directly placed in the fire door panels. Due to the limitation of perlite board molds, the specifications are not easy to change, and the door body size is made according to customer requirements. Two The latter cannot be unified in matching, so that it takes a lot of time to cut the perlite board. Generally, the filling materials in fire doors have poor fireproof effect and high preparation cost. Contents of the invention [0003] The object of the present invention is to provide a filling material for fire doors, which has good fire prevention effect and low preparation cost, and is suitable for being widely used in the field of fire doors. [0004] Technical scheme of the present invention is as follows: [0005] A filling material for a fireproof door. The raw materials...
