High-strength fireproof wooden door

Abstract

The invention discloses a production method for a high-strength fireproof wooden door. The method comprises the following steps of: (1) preparing a door panel: preparing raw materials in parts by weight: 10 parts of light burned magnesia powder, 2-2.5 parts of magnesium sulfate, 0.05 part of chitosan, 0.05 part of magnesia-alumina spinel, 0.6 part of pine sawdust, 1-1.5 parts of starch sodium octenylsuccinate, 0.8 part of starch phosphate, 0.1-0.2 part of tourmaline powder, 0.8-1 part of andalusite powder, 0.8 part of organosilicon waterproofing agent powder, 0.08 part of nano-silica, 0.1 part of polypropylene fibers, 8-10 parts of water and 2-3 parts of foam; dissolving magnesium sulfate to form a magnesium sulfate solution; adding the other raw materials into the magnesium sulfate solution except the foam, stirring the solution uniformly, then adding the foam, and stirring the solution uniformly to obtain slurry; pre-treating and curing the slurry to obtain the fireproof door panel; and (2) combining a door frame, a door panel decorating surface and the door panel together to obtain the wooden door.

Description

technical field [0001] The invention relates to a high-strength fireproof wooden door, which is applied in the field of production and processing of wooden doors. 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 in the product standa...

AI Technical Summary

Problems solved by technology

For a long time, the quality problems of magnesite foam door core panels mainly focus on the following aspects: 1. The door panel is corroded due to brine and moisture return; Strong resistance, serious glue consumption, resulting in increased glue costs, and even degumming and hollowing of door panels; Fourth, poor fire resistance, high loss rate of core material quality, resulting in fire door inspections failing to meet fire resistance time limit requirements; in addition, there are specifications Problems such as deviation and excessive deviation of flatness

[0004] The prior art discloses a wooden door with excellent performance, which includes: 13-15 parts of lightly burned magnesia powder, 3-4 parts of magnesium sulfate, 0.5-0.8 parts of trehalose, 0.1-0.2 parts of tourmaline powder, 0.2-0.3 parts of Kyanite powder, 0.5-0.6 part of organic silicon waterproof agent powder, 0.05 part of nano-titanium dioxide, 0.03 part of wax stone, 0.07-0.08 part of polypropylene fiber, 0.05-0.08 part of crushed crop straw, 8-10 part of water and 2 -3 parts of foam; but its moisture content is still high, and its mechanical properties are not good enough
