Technical Field
The invention relates to a fireproof door plate, in particular to a fireproof door plate with high nail-holding power.
Background
Fireproof door plant on the existing market has two kinds, one kind is wooden fireproof door plant: performing flame retardant treatment on wood, and filling a non-combustible heat-insulating material between two door faces; the other is a metal fireproof door plate: and noncombustible heat insulating materials are filled between the metal door faces. Fire departments have hard regulations on fire door panels used in public places to prevent the spread of fire. In general, the sheets, especially plastic sheets, with the added reinforcing fibers cannot be nailed despite their high strength and hardness, have poor nail holding effect, and are not favorable for multi-position drilling nail jointing.
Disclosure of Invention
In view of the deficiencies of the prior art, the present invention provides a fire door panel having superior strength and high nail-holding power.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the fireproof door plate with high nail-holding power is formed by mixing magnesium oxide, magnesium chloride, wood particles, water, vitrified micro bubbles, citric acid and fibers, wherein the weight ratio of the raw materials is as follows: 23-47% of wood particles, 35-40% of magnesium oxide, 8-20% of anhydrous magnesium chloride, 20-35% of water, 0-2% of vitrified micro bubbles and 0-0.5% of fibers.
On the basis of the technical scheme, the wood particles are surrounded by a mixture composed of magnesium oxide, magnesium chloride, water, vitrified micro bubbles, citric acid and fibers, and can be uniformly dispersed in the space of the mixture at different positions.
Further, the wood particles are surrounded by a mixture of magnesium oxide, magnesium chloride, water, glass beads, citric acid and fibers, and the content of the wood particles in the surface layer is less than that in the core layer.
The wood particles are obtained by processing wood processing residues, small-diameter wood and twigs as raw materials, have the water content of 8-15 percent, the size of 5-30mm in length, 3-13mm in width and 2-10mm in thicknesso
The magnesium oxide refers to a magnesium oxide product with the magnesium oxide content of more than 70 percent.
The magnesium chloride has a water content of less than 3%.
Further, the above-mentioned vitrified small balls are closed-cell vitrified small balls having a diameter of less than 4 mm.
The fiber is at least one of polypropylene fiber, polyvinyl alcohol fiber, wood fiber, bamboo fiber and other plant fiber with the length less than 12mm and the diameter less than 1.2 mm.
Compared with the prior art, the invention has the beneficial effects that:
the fireproof door plate is formed by mixing magnesium oxide, magnesium chloride, wood particles, water, vitrified micro bubbles, citric acid and fibers, has reasonable formula of each component, has good fireproof performance and high nail-holding power, has standard burning time of more than 30min when the thickness is 40mm, and has the nail-holding power of 400-2000N of a standard screw with the diameter of 2.8 mm. The fireproof door plate is easy to disassemble and assemble, convenient, quick and safe to install and disassemble, convenient to support and operate, favorable for organization and construction, good in market application prospect and good in applicability.
