The solid wood fiber material is subjected to halogen return prevention treatment.
The anti-dehalogenation treatment comprises the step of treating the solid wood fiber material by using paraffin, drying oil, beeswax, silicone oil or linseed oil and the like.
The fireproof plate achieves A-level fire prevention, the plate is burnt at the high temperature of 1500 ℃ for 10min, and the burnt thickness of a 2.0cm plate is only 2 mm.
A preparation method of a solid wood fireproof sound absorption fiberboard is characterized by comprising the following steps:
step one, adding clear water into a solid wood fiber material to enable the water content of the solid wood fiber material to be 10% -50%;
step two, performing anti-halogen return treatment on the solid wood fiber material, standing for a period of time, adding a forming agent magnesium oxide, and continuing stirring;
adding a passivating agent, a stabilizing agent and a light filler, continuously stirring, adding a magnesium chloride solution with the Baume degree of 15-30%, and uniformly stirring;
step four, placing the material treated in the step three into a die of a press machine, and carrying out cold pressing and shaping according to the required density;
and step five, placing the cold-pressed and shaped plate in a drying cellar for maintenance and solidification, and cutting edges to form the plate.
The solid wood fireproof sound absorption fiberboard has the beneficial effects that through the interaction of various chemical components, a ternary gel system of magnesium chloride, magnesium oxide and water is used for filling gaps on a wood fiber framework, and in combination with a passivating agent capable of enhancing the stability with other components including fillers, the solid wood fireproof sound absorption fiberboard can achieve the A-level fireproof standard while retaining wood fibers of a wood board main body.
The fireproof sound absorption fiber board has good sound insulation effect; the fireproof and sound insulation board can be integrated in the process, the sound insulation can be completed without adding a sound insulation material, the fireproof performance reaches A level, the fireproof treatment is not needed to be carried out independently, and the fireproof and sound insulation board can be widely applied to occasions such as KTV, cinemas, pedicures, hotels, machine rooms, outdoor doorheads, trestles, pavilions, fences, floors, wallboards, cemetery tombstones, highway extension walls, waiting kiosks and the like.
