The utility model provides a magnesite fireproof door core board, which includes an inner core, a surface board and a middle layer, wherein the inner core is formed by splicing wooden strips at intervals, and adjacent wooden strips are glued by short boards. The surface of the inner core is provided with an intermediate layer, the surface of the intermediate layer is provided with a surface layer plate, and the inner core, the surface layer plate and the intermediate layer are fixed by adhesive. The scheme has the advantages of reasonable structure, fire prevention and low preparation cost.
Description
Technical Field
The utility model belongs to the technical field of furniture technique and specifically relates to indicate a magnesite fire door core board.
Background
The traditional magnesite fireproof door core board is formed by pressing and compounding magnesium oxychloride inorganic material through mechanical line production, and then is subjected to polishing and slurry spreading treatment, so that the surface is smooth.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, provide a magnesite fire door core that is rational in infrastructure, fire prevention, preparation are with low costs.
In order to achieve the above object, the present invention provides a technical solution: the magnesite fireproof door core board comprises an inner core, a surface board and an intermediate layer, wherein the inner core is formed by splicing battens at intervals, adjacent battens are fixedly bonded through short boards, the intermediate layer is arranged on the surface of the inner core, the surface board is arranged on the surface of the intermediate layer, and the inner core, the surface board and the intermediate layer are fixed through viscose glue.
The surface layer plate is formed by pressing magnesium oxychloride inorganic material.
The middle layer is made of mesh cloth or metal mesh sheets.
The length of the battens is equal to or less than that of the inner core, the length of the short plates is 5-10cm, and the number of the short plates between adjacent battens is three to five.
By adopting the above technical scheme, the utility model, the intermediate level, the surface layer board is two-layer, be located inner core surface and bottom respectively, adopt the stuff, the inner core that the short slab splices into can effectively reduce the weight of a core board, reduce the use amount of plank simultaneously, thereby reduce manufacturing cost, the stuff, the thickness of short slab adjusts according to the thickness of a board, adopt netted intermediate level, both carry on spacingly to the inner core, increase the anti crack strength of core simultaneously, the surface layer board that adopts chlorine oxygen magnesium inorganic material press forming has the fire prevention, fire-retardant function, therefore, this scheme has rational in infrastructure, prevent fires, advantage that manufacturing cost is low.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to the attached drawing 1, the magnesite fireproof door core board comprises an inner core 1, a surface board 2 and a middle layer 3, wherein the inner core 1 is formed by splicing battens at intervals, adjacent battens are bonded and fixed through short boards, the length of each batten is equal to or less than that of the inner core, the length of each short board is 5-10cm, and the number of the short boards between the adjacent battens is three to five. The surface of the inner core 1 is provided with an intermediate layer 3, the intermediate layer 3 is made of mesh cloth or metal mesh, the surface of the intermediate layer 3 is provided with a surface layer plate 2, the surface layer plate 2 is pressed and formed by adopting a magnesium oxychloride inorganic material, and the inner core 1, the surface layer plate 2 and the intermediate layer 3 are fixed through viscose glue. After adopting above-mentioned scheme, the embodiment, the intermediate level, the surface laminate is two-layer, be located inner core surface and bottom respectively, adopt the stuff, the inner core that the quarter butt splices into can effectively reduce the weight of a core board, reduce the use amount of plank simultaneously, thereby reduce manufacturing cost, the stuff, the quarter butt thickness is adjusted according to the thickness of a door plate, adopt netted intermediate level, both carry on spacingly to the inner core, increase the crack resistance strength of core board simultaneously, the surface laminate that adopts magnesium oxychloride inorganic material press forming has the fire prevention, fire-retardant function, therefore, the embodiment has rational in infrastructure, prevent fires, advantage that manufacturing cost is low.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
