Formed the left triangle wing and the right triangle wing, the acupuncture nonwoven layer of cloth be water swelling type high water-absorption fiber through multiple acupuncture,
The air permeable waterproof nonwoven fabric construct of hot rolling treatment.
Preferably, the fibre fineness of described water swelling type high water-absorption fiber is 2D-6D, fibre length is 38mm-
12mm。
Preferably, the bottom surface of the described left triangle wing is provided with the first groove launched along base length direction, the right side
The bottom surface of delta wing is provided with the second groove launched along base length direction, and the bottom of the central part of the base portion is formed with
One concave surface, is respectively equipped with the first bonding layer, the second bonding layer in first groove, the second groove.
Preferably, the first described bonding layer, the second bonding layer are pressure sensitive adhesive layer or cold bonding type adhesive layer, and surface
It is equipped with taking off protection film layer.
Preferably, the first described bonding layer, the second bonding layer are magnetic recording tape.
Preferably, the central part of described base portion be embedded with along sealing strip length direction launch set glass wire or
Polyester line braid over braid.
Preferably, the described left triangle wing is provided with elongated portion, and elongated portion bends and surrounds a ditch with the left triangle wing
Groove.
Compared with prior art, the beneficial effects of the utility model are：
The air permeable waterproof automobile sealing strip that the utility model is provided, its sealing is from the high water-absorption fiber by water swelling
Through needle punched non-woven fabrics structure obtained by the treatment such as multiple acupuncture, once absorbing moisture, the high water-absorption fiber of non-woven fabrics will expand
It is big to itself several times, it is dry and comfortable ventilative when not absorbing water, gas permeability is balanced with water proofing property, the design of its base portion is unique, sealing
Bar can firmly be connected with car door, prevent sealing strip from deforming, good airproof performance.
Below in conjunction with the accompanying drawings with embodiment, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is overall structure schematic cross-section of the present utility model.
Specific embodiment
With reference to Fig. 1, the air permeable waterproof automobile sealing strip that the present embodiment is provided, including base portion 1 and sealing 2, sealing by
