The Chinese utility model patent with the application number of 201620825574.7 entitled "a high-efficiency subway track acoustic board" discloses a high-efficiency subway track acoustic board, which comprises a base layer, a ceramsite layer, a honeycomb layer, an air layer and an acoustic layer which are sequentially arranged from bottom to top; the honeycomb layer is composed of a group of hexagonal honeycomb cavities, each hexagonal honeycomb cavity comprises a through hole and a blind hole, sand and stone are filled in the through holes, and glass wool is filled in the blind holes; a sound transmission column is arranged in the blind hole, a sound absorption ball is fixed at the top of the sound transmission column, and the sound absorption ball is arranged in the air layer; and a group of sound absorption holes are formed in the sound absorption layer. However, the product still has poor sound absorption effect, is easy to damage and has short service life.
Disclosure of Invention
In order to solve the problem, the utility model discloses a ground rail way high efficiency is inhaled sound melamine bubble cotton board inhales sound, shock attenuation effectual, and is not fragile moreover, long service life.
The technical scheme of the utility model is that:
the utility model provides a cotton board of melamine bubble is inhaled to subway track high efficiency, includes the cotton layer of melamine bubble, adopts the cotton sound absorbing effect of melamine bubble good, difficult damage moreover, long service life, the top on the cotton layer of melamine bubble is equipped with the honeycomb layer, and the honeycomb layer is equipped with a plurality of hexagonal honeycomb cavities, hexagonal honeycomb cavity includes through-hole and blind hole, the through-hole intussuseption is filled with the polyurethane elastomer, and the shock attenuation is effectual, the blind hole intussuseption is filled with chloroprene rubber, and make full use of chloroprene rubber has higher tensile strength, elongation and reversible crystallinity, and the adhesion is good, and is ageing-resistant, heat-resisting, resistant oily, resistant chemical corrosion is excellent.
Furthermore, the honeycomb layer is made of mineral slag wool material, so that the sound absorption effect is improved, and the maintenance cost is reduced.
Further, the honeycomb layer outside is equipped with the inoxidizing coating, the inoxidizing coating is the polyethylene layer, and is stand wear and tear, corrosion-resistant, the polyethylene layer is polyethylene granule anticorrosion glue film, polyethylene granule anticorrosion glue film is formed by the granule bonding of a plurality of dispersions, and light, anti striking, ageing-resistant, stretch-proof, resistant ultraviolet radiation, bonding strength are high.
Furthermore, a waterproof layer is arranged below the melamine foam layer, and the waterproof layer is a rubber asphalt layer, so that the waterproof effect is good, the damage is not easy, and the service life is long; the lower part of the rubber asphalt layer is a wear-resistant gravel layer, so that the structural strength is improved, and the rubber asphalt layer is puncture-resistant and wear-resistant.
Furthermore, a reinforcing net layer is arranged in the melamine foam layer, the reinforcing net layer is formed by vertically interweaving glass fibers and steel wires serving as warps and wefts respectively, the warps and the wefts are all located between 1 mm and 5mm, and the diameters of the warps and the wefts are all located between 0.3 mm and 0.8 mm.
The utility model has the advantages that: sound absorption and shock absorption effects are good, and the sound absorption and shock absorption device is not easy to damage and has long service life.
