Abstract
The utility model discloses a car gadget combined material, its from the top down includes precoat (1), central core (2) and stratum basale (3) in proper order, it still includes thermoplastic cement rete (4), establish between precoat (1) and central core (2) thermoplastic cement rete (4), thermoplastic cement rete (4) are equipped with the thermoplastic cement rete of interval distribution bore for 0.4mm -0.9mm hole (401) for the surface, central core (2) are the fine felt of PP glass of polypropylene fibre fibre and glass fiber constitution, and wherein, the shared percentage of glass fiber is percent 30 to percent 70 in central core (2). The utility model has the advantages that the dead weight is light, and the absorbing effect that gives sound insulation is good, still has certain structural strength and hardness simultaneously.
Description
Technical field
The utility model relates to a kind of automobile decoration piece composite.
Background technology
Automobile oneself through as a kind of quite universal vehicles, level of comfort when riding in an automobile more and more receives the concern of people.At this wherein, how making to be in automobile in a relatively quiet comfortable environment, is exactly an important problem.
Sound is a kind of ripple, is also a kind of energy, is that object vibrations are undertaken propagating by medium.And noise is the one of sound, its penetration power is very strong.Automobile noise refers to that noise that noise source sends is by importing in car with car body generation resonance.Automobile noise can be divided into construct noise, airborne noise, resonance noise three bulk by route of transmission.Must produce according to noise source be divided into wind to make an uproar, make an uproar in road, engine noise, outer loop noise etc.
Remove internal car noise from being macroscopically divided into two kinds: one is administered from occurring source, and a kind of is exclude on the route of transmission of noise.All in most cases select second method.
In general, any one material has the ability of damping, sound insulation, sound-absorbing all to some extent.Intercept the effective way of noise transmission mainly: sealing, damping, sound insulation, sound-absorbing.Sound insulation, sound-absorbing and encapsulation process are carried out again in the basis of damping, just can reach relatively quiet comfortable degree.The acoustic material be generally applied on automobile roughly has several as follows: composite, pure PET material, polypropylene fibre glass fiber material, and the acoustic material that automobile uses should require below As soon as possible Promising Policy: 1, from heavy and light; 2, sound insulation within the specific limits, sound absorption qualities is good and can maintain a long-term stability; 3, there is certain structural strength and hardness; Existing acoustic material can not meet three above-mentioned requirements simultaneously.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of from heavy and light, sound insulating and absorbing is effective, also has the automobile decoration piece composite of certain structural strength and hardness simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of automobile decoration piece composite, and it comprises precoat, central core and basalis from top to bottom successively; It also comprises thermoplastic cement rete; Described thermoplastic cement rete is located between precoat and central core; Described thermoplastic cement rete is the thermoplastic cement rete that surface is provided with that bore spaced apart is the hole of 0.4mm-0.9mm; Described central core is the PP Chopped Strand Mat that polypropylene fiber and glass fibre are formed, and wherein, the percentage in central core shared by glass fibre is seven ten ten to percent 3 percent.
Preferred as one, described precoat is with one or several in cotton, fiber crops, hair, silk and yarn, manually or mechanical technology carries out knitting, synthetic tuft or be formed by weaving.
Preferred as one, described basalis is nonwoven layer.
Preferred as one, the surface density of described central core is 600-2000g/m2.
After adopting above structure, the utility model compared with prior art, has the following advantages: 1, mechanical property: central core adopts polypropylene fiber and glass fiber material to form, and the percentage simultaneously in central core shared by polypropylene fiber is ten to seven 13 percent.Glass has good mechanical property, plays the skeleton function of whole product; Polypropylene fibre has thermoplasticity, plays the effect of binding agent, and both ensure that the nonwoven cloth material that composites structural strength and hardness are better than pure PET and make.And the ratio of glass can be regulated to control the intensity of whole part, meet mechanical requirements in various degree; 2, acoustical behavior: have the thermoplasticity glued membrane of micropore can play the effect of bonding central core and precoat; Thermoplastic cement rete also has the effect of reflective sound wave simultaneously, improves the sound-insulation capability of part; When noise sound wave is by precoat, the blanket face of napping can first absorb a part of noise, then in inside, sound wave through thermoplastic cement rete micropore thus increase the sound wave path of propagating in central core, cause more sound wave to be absorbed by central core, make this composites have good sound-absorbing effect; Further, by the adjustment of technique, can control the size of micropore, regulate the effect of sound absorption, the effect absorbing sound on the whole and insulate against sound can be met the demands, and this is better than pure PET material and pure polypropylene fibre glass fiber material; 3, composite performance under equal grammes per square metre is good, therefore, it is possible to accomplish lighter deadweight.
