Embodiment 1

[0017] Example 1, such as figure 1 As shown, a fireproof gypsum board includes dry and chemically treated wood as the inner core 1, and the volume of the inner core 1 accounts for 1\4~1\3 of the entire gypsum board volume, preferably less than 1\4. The periphery of the inner core 1 is wrapped by filler 5 , and the outer surface of the filler 5 is provided with a glass fiber layer 4 ; radial ribs 2 and axial ribs 3 are arranged on the inner core 1 . Radial ribs 2 and axial ribs 3 are also made of fireproof fibers, and then filler 5 is added to wrap inner core 1, radial ribs 2 and axial ribs 3, which not only strengthens the connection between layers, but also Change the original structure that requires laying fibers layer by layer, and achieve the purpose of fire protection through radial ribs 2 and axial ribs 3 . After the filling material 5 is all solidified, then lay a layer of glass fiber layer 4 on the surface of the filling material 5 to strengthen the fire prevention ef...

Abstract

A fireproof gypsum board comprises an inner core, wherein the periphery of the inner core is surrounded by filler; a glass-fiber layer is arranged on the outer surface of the filler; radial ribs and axial ribs are arranged on the inner core. The fireproof gypsum board solves the problem that the structure that a plurality of glass-fiber layers are connected is laid in an original gypsum board, and plays a fireproof role through the arrangement of the radial ribs and the axial ribs; the fireproof function can also reach the national standard; the connection strength of the whole gypsum board is improved greatly, the fire retardancy of the joints of the gypsum boards is also improved, and the cost of the whole fireproof gypsum board is lowered.

Description

technical field [0001] This invention relates to building materials, in particular plasterboard for fire protection. Background technique [0002] There are many types of gypsum boards on the market, including paper gypsum boards, fiber gypsum boards and hollow gypsum strips. It is a new product innovatively developed on the basis of traditional gypsum board. It not only has all the advantages of gypsum board, but also adds some additives to the core of the gypsum board to make the fire-resistant time longer, thus playing a role The effect of blocking the spread of flames bought precious time for escape. [0003] The existing fire-resistant gypsum boards are basically added with layers of glass fibers inside, which is very effective, but the price is high, and multiple layers of glass fibers need to be laid. Contents of the invention [0004] The object of the present invention is to solve the technical problems mentioned above, and to provide a fireproof gypsum boar...
