Method for manufacturing recycled fiber insulation board for fireproof doors and the recycled fiber insulation board thereof

Abstract

The present disclosure relates to a method for manufacturing a recycled fiber insulation board for fireproof doors that has excellent thermal insulation and is optimized for conditions required for a filling material for fireproof doors by using a fiber-based insulation material that is difficult to dispose of as waste, and a recycled fiber insulation board manufactured by the method. The present disclosure provides a recycled fiber insulation board having random fiber orientation and excellent water repellency by processing fiber-based insulation material waste, which has conventionally been disposed of by landfill, through a relatively simple method, thereby providing a recycled fiber insulation board for fireproof doors that has excellent heat resistance, thermal insulation, strength, and moisture resistance at low cost. Accordingly, the present disclosure has an effect of improving the quality of fireproof doors to which the recycled fiber insulation board is applied as a filling material while reducing manufacturing costs.
