Preferably, a reinforcing bracket is provided in the coconut flake layer, and the reinforcing bracket is located between adjacent through holes.

Preferably, the first black pine particle layer is bonded to the first glass magnesium composite board layer through a silicate inorganic fireproof adhesive, and the second black pine particle layer is bonded to the second glass magnesium composite board layer through a silicate inorganic fireproof adhesive. bonding.

Compared with the prior art, the beneficial effects of the utility model are: the sound-insulating and aging-resistant particle board is coated with paraffin wax layer on the four side elevations of the particle board, and the upper and lower parts of the particle board body The surface and the outside of the paraffin layer are coated with a thermosetting coating, which makes the particle board waterproof, avoids moisture damage, and prolongs the service life. By adding fiber layers on the upper and lower surfaces of the particle board, the particle board Due to the aging of the glue layer due to the influence of the environment, it can avoid degumming and prolong the service life. By using the coconut shredded shaving layer, the first black pine shaving layer, and the second black pine shaving layer as the core material, the coconut shredded The shavings layer absorbs formaldehyde and reduces the production of formaldehyde. It is environmentally friendly, and there are through holes in the coconut shavings layer, so that the particle board has the function of sound insulation. At the same time, a reinforcing bracket is provided on the coconut shavings layer. The black pine shaving layer and the second black pine shaving layer are provided with a metal mesh layer to improve the strength of the particle board.
