Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a sound-absorbing and shock-absorbing foam 1 in an embodiment; fig. 2 is an exploded view of the sound-absorbing and shock-absorbing foam 1 according to an embodiment. As shown in the figure, the utility model discloses a inhale cotton 1 of sound shock attenuation bubble mainly is applied to the display screen bottom shock attenuation of electronic product. The sound absorption and shock absorption foam 1 comprises a foam layer 10. The foam layer 10 is of a honeycomb structure, and sound insulation material particles are filled in the honeycomb structure of the foam layer 10. The honeycomb is the basic structure of honeycomb, is by a structure that individual regular hexagon list room, room mouth are all down or towards one side, back to back symmetrical arrangement combination forms, and honeycomb has outstanding geometric mechanics performance to, the inside packing of honeycomb of the cotton layer 10 of bubble has the acoustic barrier material granule, makes the utility model discloses a cotton layer 10 of bubble has excellent sound insulation and falls the function of making an uproar and excellent geometric mechanics performance, provides abundant holding power at the bottom of for the display screen of electronic product. The thickness of the foam layer 10 is between 3 mm and 5 mm. The thickness of the foam layer 10 is too thick, the foam layer 10 needs a large installation space, which affects the size of the electronic product, the thickness of the foam layer 10 is too thin, and the foam layer 10 does not achieve the ideal sound insulation, noise reduction and support functions, so the thickness of the foam layer 10 is most suitable between 3 mm and 5 mm. A first shock absorption layer 11, an anti-static layer 12, a fire-proof layer 13 and a first protective film layer 14 are sequentially stacked on one side of the foam layer 10. The other side of the foam layer 10 is sequentially stacked with a second shock absorption layer 15 and a second protection layer 16. First buffer layer 11 and second buffer layer 15 are that the polypropylene bubble is cotton, and the cotton absorbing of polypropylene bubble disperses external impact, has obtained good buffering shock attenuation protection effect.

The antistatic layer 12 is formed by stacking RB-048 type colorless transparent antistatic coating on the first shock absorption layer 11. The RB-048 type colorless transparent antistatic coating is prepared by adopting a high-tech coating and a conductive material adding technology, and has an excellent antistatic function on the basis of perfectly keeping the inherent physical characteristics of a substrate, taking a compound of organic and inorganic raw materials as a main component, modulating and producing through a nanotechnology, wherein the coating has colorless transparency, light transmittance of more than 83 percent, high surface hardness, excellent scratch resistance, and outstanding superstrong impact resistance and high temperature resistance, and the RB-048 type colorless transparent antistatic coating has beautiful appearance, and the utility model discloses an antistatic layer 12 is prepared by adopting the RB-048 type colorless transparent antistatic coating, and the antistatic layer 12 can prevent fingerprints and other traces from being left on the upper surface of a display screen of an electronic product during use, and can prevent dust from being adsorbed under the bottom surface of the display screen of the electronic product.

The flame retardant coating 13 is magnesium oxide glass fiber, and flame retardant coating 13 has promoted the fire prevention high temperature resistance ability of inhaling the cotton 1 of sound shock attenuation bubble, prevents because the high temperature that produces when electronic product uses or the short circuit for a long time, causes to inhale the cotton 1 of sound shock attenuation bubble and fires, and then causes whole electronic product to damage.

A first adhesive layer 17 is arranged between the foam layer 10 and the first shock absorption layer 11. A second adhesive layer 18 is arranged between the foam layer 10 and the second shock absorption layer 15. First bond line 17 is fire-proof glue with second bond line 18, and fire-proof glue has excellent fire prevention and high temperature resistance, makes between bubble cotton layer 10 and the first buffer layer 11, bonds firmly between bubble cotton layer 10 and the second buffer layer 15, does not receive the influence of high temperature to cause and drops, has prolonged the life who inhales the cotton 1 of sound shock attenuation bubble.

The first protective film layer 14 and the second protective film layer 16 are release film layers. Both function to protect the first protective film layer 14 and the second protective layer 16 from damage during packaging or shipping of the first protective film layer 14 and the second protective layer 16. Inhale the cotton 1 of sound shock attenuation bubble and before using, tear first protective film layer 14 and the release paper of second protective layer 16 respectively earlier, directly attach second protective layer 16 in the preset position of electronic product, prevent to inhale the attached in-process bubble of the cotton 1 of sound shock attenuation bubble and appear.

To sum up, in the utility model discloses in one or more embodiments, the utility model discloses an it falls function and shock-absorbing function of making an uproar to inhale sound shock attenuation bubble cotton has excellent sound of inhaling, is difficult for producing the bubble in the display screen production installation of electronic product, promotes electronic product's quality, reduces the manufacturing cost of enterprise.
