Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of technical solution: a kind of long-life high corrugation depth automobile hair Motivation air filtering material, including filter material main body 1, filter material main body 1 is interior to be equipped with heavy caliber fibrous layer 21, the downside of heavy caliber fibrous layer 21 Equipped with hydrophobic crystalline silicon dioxide molecular sieve layer 22, hydrophobic crystalline silicon dioxide molecular sieve layer 22 can be to the erosion in air Matter is filtered out, and the downside of hydrophobic crystalline silicon dioxide molecular sieve layer 22 is equipped with wood wool acoustical cotton layer 23, wood wool acoustical cotton layer 23 The noise that engine generates is reduced, noise pollution is controlled, the downside of wood wool acoustical cotton layer 23 is equipped with vinyl acetate esters polymer Layer 24, vinyl acetate esters polymer layer 24 have humidity resistance, the steam in air can be filtered out, vinylacetate The downside of Type of Collective nitride layer 24 is equipped with fixed plate 25, is equipped with venthole 26 in fixed plate 25, venthole 26 facilitates air to be flowed Logical, the lower section of fixed plate 25 is equipped with cavity 27, and plasticity filled layer 31 is equipped in cavity 27, is equipped with flexibility on the inside of plasticity filled layer 31 Iron wire 32, flexible iron wire 32 have certain plasticity, the corrugated structure on filter material are stablized.

Referring to Fig. 2, heavy caliber fibrous layer 21 is made of masses of fibres, the dust in air can be effectively filtered out Grain.

Referring to Fig. 2, the venthole 26 of 27 two sides of cavity shifts to install, air is avoided to carry out direct convection current, improves filtering Efficiency.

Referring to Fig. 3, flexible iron wire 32 winds composition by iron wire two-by-two, 32 structure of flexible iron wire of iron wire composition is in net Shape facilitates passing through for air.

Referring to Fig. 2, the downside of filter material main body 1 is equipped with high temperature thermosetting resin 33, impregnated using high temperature thermosetting resin Internal layer filter material is done, can cause to crack when pressing corrugation to avoid resin because of the crosslinking that reacts in advance at a lower temperature, Cause corrugation depth that cannot continue to improve；But it is fully crosslinked that resin can be made to occur under subsequent higher temperature, further Keep depth when pressure corrugation.

When the utility model is specifically implemented: 32 structure of flexible iron wire can protect the corrugation depth that filter material main body 1 is formed It holds, effectively prevent the deformation of corrugation and depth to reduce, air passes through heavy caliber fibrous layer 21 at first, passes through heavy caliber fibrous layer 21 Can by air dust and particle filter out, prevent the function of its other protective layer that result in blockage and influence on engine Effect, air can filter out the corrosive gas in air using hydrophobic crystalline silicon dioxide molecular sieve layer 22, prevent such gas Body damages engine, and using wood wool acoustical cotton layer 23, wood wool acoustical cotton layer 23 can be by the noise of engine generation It is absorbed, weakens noise pollution, vinyl acetate esters polymer layer 24 can absorb the steam in air, and air is logical The venthole 26 crossed in fixed plate 25 enters cavity 27, and the venthole 26 of upper and lower two sides shifts to install, and avoids the direct convection current of air, Filter effect is influenced, high temperature thermosetting resin 33 not only has heat insulation, resin can also be avoided because mentioning at a lower temperature Before react crosslinking, cause to crack when pressing corrugation, cause corrugation depth that cannot continue to improve；But it can make to set Fully crosslinked, the further depth kept when pressing corrugation occurs under subsequent higher temperature for rouge.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
