The straight joined small board 410 is provided with several , Pin holes 420 are evenly provided on the surface of the straight-jointed small boards 410. The pin holes 420 are used for inserting wooden pins. Wooden pins are inserted into the pin holes 420 between the straight-jointed small boards 410 for mortise and tenon structural butt connection. The sound-absorbing layer The thermal insulation and sound-absorbing layer 1 300 is fixedly installed on the top of 400, and the thermal insulation sound-absorbing layer 1 300 is fixedly installed on the top of the sound-absorbing surface layer 200. The surface of the sound-absorbing surface layer 200 is evenly coated with the surface paint layer 100, and the bottom of the sound-absorbing layer 400 is fixedly connected to the thermal insulation sound-absorbing layer 2 500. The sound-absorbing bottom layer 600 is fixedly installed at the bottom of the second sound-absorbing layer 500. Specifically, the sound-absorbing layer 400 is made of coconut wood with a density of 0.5g/ ^cm3 . The size of the straight-joined small boards is 700mm long, 80mm wide, and 20mm thick. Coconut wood is directly assembled to make the sound-absorbing layer 400, which is convenient to save wood. At the same time, because there are a large number of gaps inside the coconut wood, it has the effect of reducing the quality of the sound-absorbing layer 400. Due to the large number of gaps in the sound-absorbing layer 400, when sound waves enter the interior of the sound-absorbing layer 400, the sound waves During the transmission process, it reciprocally collides with the internal structure of the coconut wood, thereby conveniently consuming the energy of the sound wave, reducing the transmission energy of the sound wave and narrowing the transmission range of the sound wave. By setting the pin hole 420 and using it in conjunction with the wooden dowel, it is convenient to pass through the tenon. The Mao structure fixedly connects the straight panels 410, which is convenient for energy conservation and environmental protection, and reduces the use of glue. The thermal insulation and sound-absorbing layer 1300 has the function of sound absorption and noise reduction, which facilitates improving the sound insulation effect of the lightweight sound-absorbing coconut wood decorative boards. The surface The paint layer 100 has a protective effect on the surface of the sound-absorbing surface layer 200, and improves the waterproof, mildew-proof, and wear-resistant properties of the sound-absorbing surface layer 200. The thermal insulation and sound-absorbing layer 2 500 has the functions of heat preservation, sound absorption, and noise reduction. The sound-absorbing bottom layer 600 has the function of sound absorption and reduction. The effect of noise.

The thermal insulation and sound-absorbing layer 300 is composed of 4mm thick glass wool felt. The thermal insulation and sound-absorbing layer 300 is used to insulate the decorative boards, absorb sound waves, and improve sound insulation and noise reduction. The sound-absorbing surface layer 200 is composed of shaved coconut wood veneers. The sound-absorbing surface The density of the layer 200 is set to 0.8g/cm3, and the thickness of the sound-absorbing surface layer 200 is set to 3mm. The paint layer 100 is formed by spraying a transparent, wear-resistant paint. The paint layer 100 is used to waterproof and resist the surface of the sound-absorbing surface layer 200. The thermal insulation and sound-absorbing layer 2 500 is composed of 4mm thick glass wool felt. The thermal insulation and sound-absorbing layer 2 500 has the same configuration as the thermal insulation and sound-absorbing layer 1 300. The thermal insulation and sound-absorbing layer 2 500 is used for decorative panels to insulate, absorb sound waves, and improve sound insulation. Specifically, the thermal insulation and sound-absorbing layer 300 formed by arranging the glass wool felt combination has the effect of improving the sound insulation effect. At the same time, the quality of the decorative board is reduced and the thermal insulation effect is improved by arranging the glass wool felt. The sound-absorbing surface layer 200 is cut by Made of coconut wood veneer, it has the function of sound absorption and noise reduction. The paint layer 100 is sprayed with transparent and wear-resistant paint to improve wear resistance, waterproof and anti-fouling properties. The thermal insulation and sound-absorbing layer 2 500 has the function of thermal insulation and noise reduction. The effect of noise.

The sound-absorbing bottom layer 600 is composed of sliced coconut wood veneer. The density of the sound-absorbing bottom layer 600 is set to 0.8g/cm ³ . The thickness of the sound-absorbing bottom layer 600 is 3mm. The sound-absorbing surface layer 200, the thermal insulation and sound-absorbing layer 1-300, the sound-absorbing layer 400, and the small boards are assembled directly. 410, pin hole 420, thermal insulation and sound-absorbing layer 2 500, and sound-absorbing bottom layer 600 are fixed and bonded in the form of adhesive. Specifically, by fixing and bonding the layers in the form of adhesive, it can improve the structure of each layer. The tightness of the connection facilitates subsequent cutting and processing of lightweight sound-absorbing coconut wood decorative panels.

The specific usage method of the utility model is as follows: when used by those skilled in the art, the shaved coconut wood is pressed, processed and cut into straight pieces 410. The size of the straight pieces 410 is set to 700mm in length, 80mm in width, and thickness in 20 mm, then pin holes 420 are opened on the surface of the straight-joined small boards 410, and wooden pins are installed inside the pin holes 420 to combine several straight-joined small boards 410, so that the straight-jointed small boards 410 are staggered up and down, forming a sound-absorbing layer 400, and then the thermal insulation and sound-absorbing layer 300 is bonded to the top of the sound-absorbing layer 400, and then the top of the thermal insulation and sound-absorbing layer 300 is bonded to the sound-absorbing surface layer 200, and the surface paint layer 100 is painted on the top of the sound-absorbing surface layer 200. 400 is bonded to the bottom of the thermal insulation and sound-absorbing layer 2 500, and then the sound-absorbing bottom layer 600 is bonded to the bottom of the thermal insulation and sound-absorbing layer 2 500 to form a lightweight sound-absorbing coconut wood decorative board, and then the lightweight sound-absorbing coconut wood decorative board is cut to a certain size.
