Abstract
The utility model discloses a kind of novel bottom backplate needle punched carpets of waterproof, it includes carpet body, PE film, surface layer, middle layer and bottom, and it is surface layer below particle that the surface of carpet body, which is equipped with particle, surface layer is equipped with PE film, it is middle layer below surface layer, middle layer is made of PET fiber, and PET fiber is polyester slice, below bottom position and middle layer, bottom lower surface is equipped with multiple recesses, is provided with through-hole in recess, carpet body is surrounded by bound edge.The utility model uses reasonable material, and manufacturing process is simple, and material price is cheap, can reduce production cost.Not only waterproof performance is powerful for this carpet, but also its L-PET fiber can be improved the density and rigidity of ontology, and can not also be damaged situation in the case where high-temperature.
Description
Technical field
The utility model relates to a kind of car kits, more particularly to a kind of novel bottom backplate needle punched carpet of waterproof.
Background technique
Existing difference auto vendor uses the bottom backplate of different materials structure.Type mainly has following 2 kinds:
PP extrusion sheet is hot-forming to be formed: rigidity is good, waterproof is good, but its resistance to low temperature is poor, low temperature brittleness, sound absorption properties
Difference, impact resistance is poor, and stone impact noise is larger.
Glass fibers felt is hot-forming to be formed: PP film+glass fibre+PET non-woven fabrics: rigidity is good, impact resistance is good, sound
Can preferably, but manufacturing process is complicated, it is at high cost, and production environment is poor.
It is simple to manufacture in conclusion existing automobile bottom backplate is difficult to have concurrently, is at low cost, integrating the excellent material of service performance
Material, in order to solve the above problem, cooperation industry need, and are badly in need of providing a kind of novel bottom guard plate material.Existing needle punched carpet is logical
Special material composition and special production technology are crossed, by test, meets waterproof, the high temperature resistant requirement of automobile bottom backplate.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of novel bottom backplate needle punched carpets of waterproof.
The utility model is to solve above-mentioned technical problem by following technical proposals: a kind of novel bottom backplate needle of waterproof
Carpet is pierced comprising: which carpet body, PE film, surface layer, middle layer and bottom, the surface of the carpet body are equipped with particle, particle
Lower section is surface layer, and it is middle layer below the surface layer, middle layer is made of PET fiber, and the PET is fine that surface layer, which is equipped with PE film,
Dimension is polyester slice, the bottom position and middle layer lower section, and bottom lower surface is equipped with multiple recesses, is provided with through-hole in recess, institute
It states carpet body and is surrounded by bound edge.
Preferably, the particle is in needle prick shape, and distribution density is 550-600 thorn/CM2, and size is 40-42 pricker.
Preferably, the rounded arrangement of the recess.
Preferably, the bound edge is rubber material.
The utility model has the advantages that: the utility model uses reasonable material, and manufacturing process is simple, and material price is just
Preferably, it can reduce production cost.Not only waterproof performance is powerful for this carpet, but also its L-PET fiber can be improved the density of ontology
And rigidity, can not also be damaged situation in the case where high-temperature.PET fiber and elongated piece built in this carpet can also increase
Strong sound absorption properties.
Detailed description of the invention
Fig. 1 is the overall schematic of the utility model.
Fig. 2 is the schematic diagram of the utility model bottom surface.
Specific embodiment
The utility model preferred embodiment is provided, with reference to the accompanying drawing the technical solution of the utility model is described in detail.
As shown in Figs. 1-2, ontology 1, PE film 2, surface layer 3, middle layer 4, bottom 5, particle 6, recess 7, through-hole 8, bound edge 9.
A kind of novel bottom backplate needle punched carpet of waterproof comprising carpet body 1, PE film 2, surface layer 3, middle layer 4 and bottom
5, the surface of carpet body 1 is equipped with particle 6, is surface layer 3 below particle 6, and it is intermediate below surface layer 3 that surface layer 3, which is equipped with PE film 2,
Layer 4, middle layer 4 is made of PET fiber, and PET fiber is polyester slice, after PET fiber and the mixing of L-PET fiber by combing and
4 structure of middle layer needed for being formed after lapping.4 lower section of bottom 5 and middle layer, 5 lower surface of bottom is equipped with multiple recesses 7, recess 7
It is inside provided with through-hole 8, carpet body 1 is surrounded by bound edge 9.
In the present embodiment, particle 6 is in needle prick shape, and distribution density is 550-600 thorn/CM2, and size is 40-42 pricker.
In the present embodiment, the rounded arrangement of recess 8.
In the present embodiment, bound edge 9 is rubber material.
The utility model uses reasonable material, and manufacturing process is simple, and material price is cheap, can reduce and is produced into
This.Not only waterproof performance is powerful for this carpet, but also its L-PET fiber can be improved the density and rigidity of ontology, in high-temperature
In the case of can not also be damaged situation.PET fiber and elongated piece built in this carpet can also enhance sound absorption properties.
Particular embodiments described above, the technical issues of to the solution of the utility model, technical scheme and beneficial effects
It has been further described, it should be understood that the foregoing is merely specific embodiment of the utility model, not
For limiting the utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
