Abstract
The utility model provides a kind of Novel acupuncture felt, it is three-decker formation, wherein ground floor is innermost layer, the second layer is base cloth layer and third layer is outermost layer, wherein adopt the sticky note innermost layer of needing machine symmetry and outermost layer, wherein base cloth layer is PET glass fibrage, and outermost layer is Teflon polyester cotton layer fiber, and innermost layer is PP+PET double component molten spraying.The utility model is formed by adopting three-layer composite structure, multilayer adopts composite cotton fabric or composite fibre can play sound insulation, noise reduction dimension, heat insulation effect, by the symmetrical gluing of needing machine, acupuncture and hot-forming, wherein utilize the noise reduction of PP cotton and high, the excellent high and low temperature resistance of PET impact strength, the sound insulation that glass fibre, polyester cotton and PTPE are high temperature resistant, acid and alkali-resistance, sound insulation, resistant to hydrolysis performance are fabulous and heat insulation effect, arrange the effect that can better reach sound insulation, noise reduction, high temperature resistance by the thickness of uniqueness.
Description
Technical field
The utility model relates to a kind of felt, is specifically related to a kind of Nomex by fiber composite.
Background technology
Automotive trim Nomex, existing automotive interior sound insulation, heat insulation and high-temperature resistant result is very bad, and when producing, felt dust-proof effect is also bad, also attractive in appearance not simultaneously.Now commercially often adopt acupuncture as noise reduction heat insulation type material, but from the feedback information in market, current used most of felt all can not reach that filter efficiency is high, high temperature resistant, acid and alkali-resistance, hydrolytic resistance are good completely, sound insulation, good in oxidation resistance filtering requirement.
Utility model content
For above problems of the prior art, it is high that the utility model provides a kind of filter efficiency, high temperature resistant, acid and alkali-resistance, sound insulation, the Novel acupuncture felt of hydrolytic resistance and good in oxidation resistance.
The utility model is achieved through the following technical solutions:
A kind of Novel acupuncture felt, it is three-decker formation, wherein ground floor is innermost layer, the second layer is base cloth layer and third layer is outermost layer, wherein adopt the sticky note innermost layer of needing machine symmetry and outermost layer, wherein base cloth layer is PET glass fibrage, and outermost layer is Teflon polyester cotton layer fiber, and innermost layer is PP+PET double component molten spraying.
Described innermost layer thickness is 0.5mm, and base cloth layer thickness is 0.4mm, and outermost layer thickness is 0.6mm.
Described Nomex is hot-forming by the symmetrical gluing acupuncture of needing machine.
The beneficial effects of the utility model are: form by adopting three-layer composite structure, multilayer adopts composite cotton fabric or composite fibre can play sound insulation, noise reduction dimension, heat insulation effect, by the symmetrical gluing of needing machine, acupuncture and hot-forming, wherein utilize the noise reduction of PP cotton and high, the excellent high and low temperature resistance of PET impact strength, the sound insulation that glass fibre, polyester cotton and PTPE are high temperature resistant, acid and alkali-resistance, sound insulation, resistant to hydrolysis performance are fabulous and heat insulation effect, arrange the effect that can better reach sound insulation, noise reduction, high temperature resistance by the thickness of uniqueness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is innermost layer; 2 is base cloth layer; 3 is outermost layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model provides a kind of Novel acupuncture felt, as shown in Figure 1, it is three-decker formation, wherein ground floor is innermost layer 1, the second layer is base cloth layer 2 and third layer is outermost layer 3, wherein adopt the sticky note innermost layer 1 of needing machine symmetry and outermost layer 3, wherein base cloth layer 2 is PET glass fibrage, outermost layer 3 is Teflon polyester cotton layer fiber, innermost layer 2 is PP+PET double component molten spraying, when mounted by outermost layer corresponding temperature or noise point, can first through the preliminary filtering high temperature of outermost layer 3 and noise, high temperature and noise are reduce temperature and noise further through base cloth layer 2, when innermost layer 1, its temperature and noise reduce again.Wherein the thickness of innermost layer 1 is 0.5mm, and the thickness of base cloth layer 2 is 0.4mm, and the thickness of outermost layer 3 is 0.6mm, and more than for this case the best is heat insulation and the effect of sound insulation, its heat energy reduced rate is 90%, and noise noise abatement rate is 80%.The Nomex of this case is hot-forming by the symmetrical gluing acupuncture of needing machine.
The utility model is formed by adopting three-layer composite structure, multilayer adopts composite cotton fabric or composite fibre can play sound insulation, noise reduction dimension, heat insulation effect, by the symmetrical gluing of needing machine, acupuncture and hot-forming, wherein utilize the noise reduction of PP cotton and high, the excellent high and low temperature resistance of PET impact strength, the sound insulation that glass fibre, polyester cotton and PTPE are high temperature resistant, acid and alkali-resistance, sound insulation, resistant to hydrolysis performance are fabulous and heat insulation effect, arrange the effect that can better reach sound insulation, noise reduction, high temperature resistance by the thickness of uniqueness.
Claims (3)
