Embodiment 1

[0018] Such as figure 1 As shown, a fireproof door frame consists of three layers of magnesium material (1) and a wooden board layer (2) sandwiched therein, and the gap between the magnesium material layer (1) and the wooden board layer (2) Bonded by glue. The wooden boards of the wooden board layer (2) are waste wood boards, and the waste wood boards are formed by bonding small pieces of wood. Magnesium material layer (1) is obtained by dispersing magnesium oxide powder with a purity of 80% in a magnesium chloride solution with a Baume degree of 23 degrees, then stirring to prepare a paste, and finally hardening the paste. The thickness of the magnesium material layer is 0.3cm, and the thickness of the wooden board layer (2) is 2cm.

Embodiment 2

[0020] Such as figure 2 As shown, a fireproof door frame is composed of six layers of magnesia material layers (1) and a wooden board layer (2) interposed therein, between the magnesium material layer (1) and the wood board layer (2) Bonded by glue. The wooden boards of the wooden board layer (2) are waste wood boards, which are formed by adding an adhesive to wood chips and then through a hot pressing process. Magnesium material layer (1) is obtained by dispersing magnesium oxide powder with a purity of 80% in a magnesium chloride solution with a Baume degree of 23 degrees, then stirring to prepare a paste, and finally hardening the paste. The thickness of the magnesium material layer is 0.2cm, and the thickness of the wooden board layer (2) is 1.5cm.

Abstract

The invention relates to a fireproof door frame, and belongs to the technical field of fireproof materials. The fireproof door frame comprises at least three magnesium material layers and wooded panel layers sandwiched between the magnesium material layers, wherein the magnesium material layers and the wooded panel layers are bonded with glue. The fire door frame has a simple structure and is convenient to use. According to the invention, the traditional fireproof door installation mode is thoroughly changed, so that a fireproof door can be manufactured on site as an ordinary door is manufactured, and accordingly, the two major problems in the prior art are solved at one stroke, which is of great significance.

Description

technical field [0001] The invention relates to a fireproof door frame, which belongs to the technical field of fireproof materials. Background technique [0002] The existing fire door frames are sold as finished products, so if they are accidentally bumped during transportation, the door panels will be scrapped. In addition, during decoration, if there is a certain degree of error in the measurement size, the decoration effect will be greatly reduced. Contents of the invention [0003] The object of the present invention is to provide a fireproof door frame to solve the above technical problems. [0004] Above-mentioned technical purpose of the present invention is achieved through the following technical solutions: [0005] A fireproof door frame, comprising a magnesium material layer and a wooden board layer, the door frame is composed of at least three magnesium material layers and a wooden board layer sandwiched therein, the magnesium material layer and the woo...
