High-strength fire resisting wooden door and production method thereof

Abstract

The invention discloses a high-strength fire-proof wooden door and a production method thereof. The high-strength fire resisting wooden door comprises a core board, wherein the core board is prepared from the following raw materials: pine sawdust, aluminum oxide, magnesium sulfate, polyurethane, silicon carbide fibers, zirconium diboride, ammonium molybdate, bamboo powder, inositol, an ethylene-vinyl alcohol copolymer, tourmaline powder, trichloroethyl phosphate, starch adhesive, 1,2-ethylene thiourea, magnesia powder, organosilicon waterproofing agent powder, a flame retardant, a foaming agent and a foam stabilizing agent. The production method of the high-strength fire-proof wooden door comprises the following steps: dissolving the magnesium sulfate into a magnesium sulfate solution, and adding other raw materials into the magnesium sulfate solution and uniformly mixing to obtain slurry; then carrying out standing, solidifying, curing and the like on the slurry to obtain the core board of the fire resisting door; finally, carrying out assembling. The production method of the fire resisting wooden door, disclosed by the invention, has the advantages of simplicity and convenience, low energy consumption and less pollution; the fire resisting wooden door also has the characteristics of low possibilities of absorbing water, generating pulverization and argillization phenomena, high strength, excellent fire-proof performance and a broad market prospect.

Description

technical field [0001] The invention belongs to the field of fireproof wooden doors, and in particular relates to a high-strength fireproof wooden door and a production method thereof. Background technique [0002] The fire door core board is a key raw material in the fire door structure. The performance of the fire door depends on the performance and quality of the door core board to a large extent. But so far, the relevant domestic standards for fire door core panels are still blank, and manufacturers only follow the descriptions of fire door filling materials in "Fire Door GB12955-2008", except that the materials must meet the requirements of flammability and non-combustibility (A1 grade ) and smoke toxicity AQ1 two mandatory conditions, materials need to meet environmental protection requirements, use of degradable materials, there are no clear regulations on more materials and physical and chemical indicators, process indicators, which makes the door panel manufacturers...

AI Technical Summary

Problems solved by technology

However, the quality problems that have appeared on the magnesite foam door core board for a long time are mainly concentrated in the following aspects: (1) brine and moisture return, and the door panel is corroded; (2) the board body is pulverized and muddy, and the strength is insufficient and attenuated; (3) Strong water absorption, serious glue consumption, resulting in increased glue cost, and even degumming and hollowing of door panels; (4) Poor fire resistance, high loss rate of core material quality, resulting in fire door inspection failing to meet fire resistance time limit requirements ; In addition, there are problems such as specification deviation and excessive flatness deviation
