Abstract
The invention discloses a sound insulation pad for a car carpet. The sound insulation pad is formed by the high-temperature fit of at least two layers of materials, wherein one layer or a plurality of layers of material is polyester fiber cotton. The sound insulation pad for the car carpet disclosed by the invention takes the polyester fiber cotton as a sound insulation vibration-proof material, thereby being non-toxic; secondly, the sound insulation pad has a three-dimensional fiber structure, so that the sound insulation pad has the resilience performance which is equal to that of the polyurethane soft foaming rubber, and is light in weight, and the weight of the perpendicular net-forming material is only 50% as heavy as the weight of the polyurethane soft foaming rubber or 60% as heavy as the weight of the common non woven material in the case of same sound insulation performance; the machining technology of the sound insulation pad for the car carpet disclosed by the invention does not relate to chemical reactions, so the sound insulation pad can be recyclable, and is energy-saving and environment-friendly; and the main material polyester fiber cotton of the sound insulation pad for the car carpet disclosed by the invention has an anti-flame effect, so that the sound insulation pad does not need to be added with fire retardant, and the sound insulation pad is good in filtering performance, large in clogging capacity and long in service life.
Description
Technical field
The present invention relates to material for car interior trim parts technical field, and in particular to a kind of Sound insulation pad for car carpet.
Background technology
Sound insulation pad for car carpet is one of indispensable automotive upholstery, and its major function is to intercept and eliminate traveling
When bottom of car toward the noise of in-car transmission, and with damping, warming and other effects, additionally trample impression with soft,
Driving and the ride quality of driver and passenger can synthetically be improved.
Existing Sound insulation pad for car carpet is mainly made up of polypropylene felt and similar blended felt or flexible polyurethane bipeltate, such as
" waste-cotton composite automotive carpet ", " one kind disclosed in patent documentation CN202130342U disclosed in patent documentation CN101716902A
" car carpeting " etc. disclosed in car carpeting ", patent documentation CN202293461U.
Need to use chemical adhesive in a large number in polypropylene felt and similar blended felt material processing, and easily by water and day
Gas affects and goes mouldy, and rebound performance is not as good as flexible polyurethane bipeltate；And for flexible polyurethane bipeltate, although its tool
There is higher rebound performance, but its material itself has toxicity, and processing technique is needed by chemical reaction, and energy consumption is higher, and should
Material not recoverable, easily causes environmental pollution, oxidizable decomposition, not with resistance unstable in addition with chemical constitution
Combustion performance, the shortcomings of there is disaster hidden-trouble.
The content of the invention
It is an object of the invention to provide a kind of Sound insulation pad for car carpet, can overcome existing Sound insulation pad for car carpet to adopt
Polypropylene felt and similar blended felt or flexible polyurethane foam rubbery material and the problem and shortage that exists.
To achieve these goals, technical scheme proposed by the present invention is：
A kind of Sound insulation pad for car carpet, forms including the laminating of at least materials at two layers high temperature, and wherein one or more layers material is
Polyster fibre cotton.The polyster fibre cotton can be by hollow pet staple fiber by addition meldable fibre glue Jing shreddings, mixed cotton, comb
Reason, lapping, drying and shaping are obtained, and specifically and preferably meldable fibre glue can be the low melting point meldable fibre of Korea 4080.
As further improved Sound insulation pad for car carpet of the invention, formed by the laminating of at least trilaminate material high temperature, top layer
For polrvinyl chloride, intermediate layer is polyster fibre cotton, and bottom is polrvinyl chloride or polystyrene.
As further improved Sound insulation pad for car carpet of the invention, also including at least one of which nonwoven layer, the nonwoven
Layer of cloth is located between the top layer and the intermediate layer, or is individually located between the bottom and the intermediate layer, or while position
Between the top layer and the intermediate layer and between the bottom and the intermediate layer.
Used as further improved Sound insulation pad for car carpet of the invention, the nonwoven layer is polyster fibre non-woven fabrics.
Used as further improved Sound insulation pad for car carpet of the invention, it is 3 denier～8 that the polyster fibre cotton is fibre fineness
The polyster fibre cotton of denier.
Used as further improved Sound insulation pad for car carpet of the invention, the quantitative specification of the polyster fibre cotton is 1000 grams
Per square meter, the thickness of the polyster fibre cotton is 20 millimeters～50 millimeters.
Used as further improved Sound insulation pad for car carpet of the invention, the top layer thickness is 0.2 millimeter～2 millimeters, institute
Underlayer thickness is stated for 1 millimeter～5 millimeters.
Used as further improved Sound insulation pad for car carpet of the invention, the bottom and top layer are provided with anti-skidding embossing.
Sound insulation pad for car carpet provided by the present invention, it is nontoxic using polyster fibre cotton as sound insulation packing；Secondly
It is with the rebound performance suitable with flexible polyurethane bipeltate and lightweight with three-dimensional fibre structure, in identical sound-proofing
The 60% of the vertical 50% or common non-woven material for there was only flexible polyurethane bipeltate into net materials weight under conditions of energy；Again
The processing technique of Sound insulation pad for car carpet provided by the present invention is not related to chemical reaction, and recoverable, energy-conserving and environment-protective；This
Outward, the main material polyster fibre cotton of Sound insulation pad for car carpet provided by the present invention has flame retardant effect, fire-retardant without the need for adding
Agent, and with good strainability, dust containing capacity is big, long service life.
Description of the drawings
Fig. 1, Sound insulation pad for car carpet structural representation.
1 is intermediate layer, and 2 is top layer, and 3 is bottom, and 4 is nonwoven layer.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and Examples is further retouched in detail
State, the embodiment is only used for explaining the present invention, does not constitute limiting the scope of the present invention.
As shown in figure 1, the present embodiment provide Sound insulation pad for car carpet, including five layer material high temperature laminating form, top layer 2
For polrvinyl chloride, intermediate layer 1 is polyster fibre cotton, and bottom 3 is polrvinyl chloride or polystyrene.Intermediate layer 1 be car carpeting every
The main functional parts of sound pad, top layer 2 and bottom 3 improve its anti-wear performance mainly for the protection of intermediate layer 1, extend it and use
