Abstract

The invention discloses a fireproof door plate with high nail-holding power. The fireproof door plate is composed of magnesium oxide, magnesium chloride, wood particles, water, vitrified micro bubbles, citric acid and fibers, and the weight ratios of the raw materials are as follows: 23 to 47 percent of wood particles, 35 to 40 percent of magnesium oxide, 8 to 20 percent of anhydrous magnesium chloride, 20 to 35 percent of water, 0 to 2 percent of vitrified micro bubbles, and 0 to 0.5 fibers. The fireproof door plate has good fireproof performance and high nail-holding power, the standard combustion time is longer than 30 min when the thickness of the fireproof door plate is 40 mm, and the nail-holding power of standard screws with the diameter of 2.8 mm is 400-2000 N.

Description

technical field [0001] The invention relates to a fireproof door panel, in particular to a fireproof door panel with high nail-holding force. Background technique [0002] There are currently two types of fire-resistant door panels on the market, one is wooden fire-resistant door panels: the wood is treated with flame-retardant treatment, and non-combustible insulation materials are filled between the two facades; the other is metal fire-resistant door panels: non-combustible insulation materials are filled between the metal facades Insulation materials. The fire department has strict regulations on fire door panels used in public places to prevent the spread of fire. Usually, although the boards added with reinforcing fibers, especially plastic boards, have high strength and hardness, they cannot be nailed and have poor nail holding effect, which is not conducive to multi-position drilling and nailing. Contents of the invention [0003] Aiming at the deficiencies of the...
