Problems solved by technology

However, as far as the current two fire door core boards are concerned, the first one is made of aluminum silicate wool as the main material. Because its smoke toxicity index does not meet the national standard, it has been banned from use now. The other is the door core board with expanded perlite as the main material. Due to the poor strength of perlite itself, after bonding with the steel plate or multi-layer board, the processing deformation, heat deformation, and collision deformation of the thin steel plate, etc. factors, it is easy to cause the core board of the fire door to crack, thus affecting the overall performance of the fire door
After the multi-layer board is bonded with the core board made of perlite, the core board is easily broken by external impact during transportation and installation. In the event of a fire, when the multi-layer board is burned out, the fire door will automatically Falling apart loses its fire protection effect

Abstract

The invention discloses a fireproof door core plate and a making method thereof, and relates to the technical field of door cores. The fireproof door core plate comprises 55-65 parts of a polymer matrix, 45-55 parts of desulfurized gypsum, 40-43 parts of borax, 37-38 parts of anhydrous magnesium chloride, 32-34 parts of cenosphere, 30-32 parts of a filler material, 26-28 parts of refractory particles, 20-23 parts of reinforcing fibers, 17-19 parts of wood powder, 16-18 parts of phosphonate, 10-15 parts of an assistant, 4-10 parts of stearic acid and 60-63 parts of water. The fireproof door core plate has the advantages of good fire resistance, good thermal insulation resistance, light weight, high strength and easiness in fragmentation.

Description

technical field [0001] The invention relates to the field of door core technology, in particular to a fireproof door core board and a preparation method thereof. Background technique [0002] At present, most fire doors are made of fire door core boards. Fire doors made of fire door core boards can not only save the skeleton support, but also simplify the production process of fire doors, improve production efficiency and reduce manufacturing costs. However, as far as the current two fire door core boards are concerned, the first one is made of aluminum silicate wool as the main material. Because its smoke toxicity index does not meet the national standard, it has been banned from use now. The other is the door core board with expanded perlite as the main material. Due to the poor strength of perlite itself, after bonding with the steel plate or multi-layer board, the processing deformation, heat deformation, and collision deformation of the thin steel plate, etc. Factors, ...
