Abstract
The utility model provides an environment -friendly sound insulation pad for cars, includes that cotton felt is cotton with the stereoplasm that bonds on cotton felt, connection edge cotton at the stereoplasm and cotton felt still is equipped with at least one thread gluing, edge cotton at the stereoplasm and that cotton felt is connected is equipped with the structure of borduring, cotton felt constitutes the material and includes polypropylene fibre fibre and fabrics waste material for the cotton felt of regeneration flame retardant fiber. For control manufacturing cost, the stereoplasm cotton mostly adopts clothing leftover bits, the blending of ordinary cotton fiber dimension to form. Compared with the prior art, the utility model provides a pair of car sound insulation spacer has is convenient for tailor, bond advantage firm, difficult fracture. Utilize the fibrous green nature of polypropylene fibre, constitute the material as the main part of the cotton felt of regeneration flame retardant fiber, can reduce harmful substance content in the car effectively, absorb the noise decibel in the car simultaneously, increased the travelling comfort of auttombilism.
Description
Technical field
This utility model relates to automobile production field, specifically a kind of environmentally friendly vehicle sound insulating pad.
Background technology
Along with the fast development of World Economics, improving constantly of living standards of the people, auto industry
Quickly grow.People are to the outward appearance that the requirement of automobile is not only beautiful design, and to inside
Comfortableness, functional, noise immunity and the feature of environmental protection of decoration are it is also proposed that carry out new requirement.
Irritating internal car noise is nothing more than from electromotor, chassis, wind noise and vehicle body sympathetic response
Deng.Current domestic popular auto sound technology is all to prevent and treat according to these noise sources,
To reach noise insulation entrance compartment, build a quiet interior space.
Utility model content
This utility model aims to provide a kind of environmentally friendly vehicle sound insulating pad.
For achieving the above object, the following technical scheme of this utility model offer: a kind of environmentally friendly vehicle
Sound insulating pad, including cotton felt and the hard cotton being bonded on cotton felt, in hard cotton and the connection of cotton felt
Edge is additionally provided with at least one thread gluing；The edge connected at hard cotton and cotton felt is provided with bound edge
Structure；Described cotton felt is regeneration fire resistance fibre cotton felt, and constituent material includes polypropylene fiber and weaving
Product waste material.
Described hard cotton is double-deck, is glued respectively to the both sides of cotton felt, and hard cotton uses clothing limit
Corner material, common cotton fiber blend form.
Textile spent material uses waste and old clothing, clothing leftover pieces and other cotton products.
Compared with prior art, the beneficial effects of the utility model are: by hard cotton and cotton
Thread gluing is set at the adjoining edge of felt, during use, only sound insulating pad need to be spread out and thread gluing is buckled
, bond firm easy to use.Simultaneously as hard cotton uses clothing leftover pieces with common
Cotton fiber blending forms, and cutting is easy.Additionally, due to the edge that hard cotton and cotton felt connect
It is provided with binding structure, effectively prevents coming off between hard cotton and cotton felt.
Utilize the environmental protection character of polypropylene fiber, as the main body structure of regeneration fire resistance fibre cotton felt
Become material, harmful substance contents in car can be effectively reduced, absorb the noise decibel in car simultaneously,
Add the comfortableness of car steering.On the other hand, Appropriate application textile spent material is as auxiliary
Material, had both enhanced the advantage of sound insulation, had reduced again the cost of product, and this utility model is made
Material more former like product material cost low by about 20%.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is the structural representation of cotton felt in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment
Technical scheme be clearly and completely described, it is clear that described embodiment be only this
The a part of embodiment of utility model rather than whole embodiments.Based in this utility model
Embodiment, those of ordinary skill in the art are obtained under not making creative work premise
Every other embodiment, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, in this utility model embodiment, a kind of environmentally friendly vehicle sound insulating pad, bag
Include cotton felt 1 and the hard cotton 2 being bonded on cotton felt 1, in hard cotton 2 and the connection of cotton felt 1
Edge is additionally provided with at least one thread gluing 3.
Described hard cotton 2 is double-deck, is glued respectively to the both sides of cotton felt 1, have preferably every
Audio fruit, hard cotton uses clothing leftover pieces, common cotton fiber blend to form, can effectively control
Production cost.
By arranging thread gluing at the adjoining edge of hard cotton and cotton felt, only need to be by sound insulation during use
Pad spreads out and thread gluing is buckled, and bonds firm easy to use.Simultaneously as hard cotton is adopted
Forming with clothing leftover pieces and common cotton fiber blend, cutting is easy.
The edge connected at hard cotton 2 and cotton felt 1 is provided with binding structure 4, binding structure 4
Can effectively prevent coming off between hard cotton and cotton felt.
Described cotton felt 1 is regeneration fire resistance fibre cotton felt, and constituent material includes polypropylene fiber and weaving
Product waste material, wherein the mass percent of polypropylene fiber is 2%-95%, the regeneration constituted with this
Fire resistance fibre cotton felt grammes per square metre is 500-1300g/m2.Textile spent material uses waste and old clothing, clothing
Leftover pieces and other cotton products.
Cotton felt 1 uses regeneration fire resistance fibre cotton felt, has enough Air permenbilities, plentiful resilience
The advantages such as power, nontoxic, clean environmental protection water-fastness, fire-retardant, wherein primary raw material polypropylene is fine
The cotton good springiness of dimension, bulkiness is strong, handsome in appearance, is not afraid of extruding, washable.
Compared with currently used phenolic resin cotton sound insulating pad, this utility model uses regeneration fire-retardant
Cellucotton felt, remarkably productive in terms of sound-absorbing sound insulation, can effectively reduce the noise decibel in car,
Add the comfortableness of car steering.Owing to regeneration fire resistance fibre cotton felt can recycle weaving
Product waste material, is having extraordinary advantage in price, can effectively reduce the cost of product, this reality
Low by about 20% with novel used material more former like product material cost.
