▎ 摘　　要

NOVELTY - High elastic auxiliary air purifying vehicle interior sound absorbing cotton comprises high elastic supporting layer (1). The upper and lower two sides of the high elastic supporting layer is provided with an elastic porous net layer (2). The porous net connecting permanent magnet (4) and a supporting layer connecting permanent magnet (5) are arranged at the connection position of the elastic porous net layers and the horizontal side of the high-elasticity supporting layer. The porous net connecting permanent magnet is embedded in the elastic porous net layers, and the supporting layer connecting permanent magnet is embedded in the high-elasticity supporting layer. The middle portion of the elastic porous net layer is provided with a through connecting column (6). USE - High elastic auxiliary air purifying vehicle interior sound absorbing cotton used in a sound absorbing material-glass cotton. ADVANTAGE - The interior material is capable of absorbing and decomposing formaldehyde, benzene, TVOC and other toxic and harmful gas of good sound insulation and silencing effect. The multi-layer overlapped attracting sound insulation material is high-efficient insulating noise, creating a quiet and quiet environment in the vehicle, the working efficiency is good and the benefit is high. The raw material is firmly adhered to each layer, without cracking, the surface is not convex, and the whole is flat. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high elastic auxiliary air purifying vehicle interior sound absorbing cotton, which involves casting elastic porous mesh layer and the aluminum alloy mesh frame inserted into the high elastic support layer obtained by casting the mold in the casting mold in advance, adding porous mesh to connect the permanent magnet, the support layer is connected to the permanent magnet, and the through-column is connected to the permanent magnet so as to be embedded in the highly elastic support layer and the elastic porous mesh layer respectively, trimming and grinding the obtained high elastic support layer and elastic porous mesh layer to obtain an installation groove and a socket for inserting the aluminum alloy mesh frame, repeatedly hot-pressing the organic bi-component cotton layer, the microporous non-woven fabric layer and the inorganic bi-component cotton layer, the foam plastic sound insulation layer and the brake pad slag layer, until the raw materials of each layer are firmly adhered, not cracked, the surface has no protrusions, and the whole is flat, correspondingly filling the air purification layer, the organic two-component cotton layer, the microporous non-woven fabric layer, the inorganic two-component cotton layer, the foam sound insulation layer, the air freshening layer and the brake pad slag layer in the upper cavity formed by the high elastic support layer and the elastic porous mesh layer and are opened in the middle of each layer, there are through holes for installing the connecting posts on the elastic porous mesh layer, connecting elastic porous mesh laye to the permanent magnet through the porous mesh, connecting support layer to the permanent magnet, connecting through-column to the permanent magnet, performing the same operation on the lower side of the high-elasticity support layer, after turning it over, insert the aluminum alloy mesh frames on the upper and lower sides of the high-elasticity support layer into the corresponding jacks, and then check the overall sound insulation cotton again, after grinding and trimming, the interior sound-absorbing cotton is obtained DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a high elastic auxiliary air purifying vehicle interior sound absorbing cotton. 1High elastic supporting layer 2Elastic porous net layer 4Porous net connecting permanent magnet 5Permanent magnet 6Connecting column
