Abstract

The invention belongs to the technical field of constructional engineering, and particularly relates to a preparation method of a fireproof door leaf. The technical key points are as follows: the fireproof door leaf consists of a door core, a frame and a decorative panel; a preparation method of the door core comprises the following steps that a door core material is flatly laid in a mold; uniformly spraying a modified adhesive into the groove body structure in a mist form, so that the solid mixtures are bonded together in sequence; and curing and forming to obtain the door core. By means of the micro-expansion effect, the door core generates certain extrusion force on the frame in the curing process, frame materials are bonded, chemical bonds and pushing force are generated between the door core and the frame, and the binding force between the door core and the frame is further improved.

Description

Technical field [0001] The invention is a technical field in the field of construction engineering, and it involves a method of preparation of a fire door fan. Background technique [0002] The traditional fire door on the market is a five -layer structure, and it is a fireplate, a cork frame, and a magnesium chloride plate core, a glass magnesium plate or a calcium silicate plate such as a fireplace, a cemented on the glass plate or a calcium silicate plate, The tablet panel, the cork frame and chlorine magnesium door core in the above structure are relatively weak, have short refractory time, cumbersome production process, and high cost. [0003] In order to overcome the above -mentioned defects, in the existing technology, the frame of the door fan usually forms the door core, and the door core is poured in it. This method not only greatly extend the fire resistance time, but also has a simple production process and low cost. However, because the door core uses the method of p...
