Description

A SELF-SEALING CAP STRIP
Field of the Invention
The present invention relates to a cap strip which provides sealing to the tire by being wound in strips between the tread and the steel belt in pneumatic radial vehicle tires used in motor vehicles.
Background of the Invention
In order to provide sealing in radial vehicle tires used today, the spacing between the carcass and the inner layer is coated with an elastomeric layer. However, the sealing decreases in this kind of tires in time with the effect of centrifugal force. Besides, the tacky nature of elastomeric materials causes difficulties in processing and use. In order to prevent the said problem, the said layer is coated with an extra protective film and this film is removed after the vulcanization process. All these processes are disadvantages in terms of time and cost.
United States Patent document no US2011198010, an application known in the state of the art, discloses an elastomer composition providing sealing vehicle tires. In the said composition, unsaturated diene elastomer and thermoplastic hydrocarbon plasticizer resin is used.
International Patent document no WO2011092124, an application known in the state of the art, discloses an elastomeric layer preventing the tire blowout and providing sealing by being coated inside the tire. The said elastomeric layer is obtained by mixing unsaturated diene elastomer, hydrocarbon resin, filler and thiuram polysulfide.
Summary of the Invention
The objective of the present invention is to provide a self-sealing cap strip which is placed between the tread and the steel belt in tires. Another objective of the present invention is to provide a self-sealing cap strip which prevents the tire blowing out in short time.
A further objective of the present invention is to provide a self-sealing cap strip which prevents the tire blowing out as a result of environmental factors such as road and weather conditions.
Yet another objective of the present invention is to provide a self-sealing cap strip which is comprised of polymeric cords and elastomeric filling materials.

at least two layers (2) located on top of each other,
cords (3) which are aligned next to each other within the layer (2), at least one filling material (4) which fills the spacings between the cords (3) within the self-sealing layer (2) and enables the cords (3) to stay together. The self-sealing strip layer (2) is a layer which has polymeric cords (3) arranged next to each other and at least one elastomeric filling material (4) by holding the cords (3) together as well as providing sealing. The self- sealing layer (2) is located within the cap strip package (1) as at least two layers on top of each other or single layer strips (2) is wound between the tread (S) and the steel belt (K) as at least two layers. In the preferred embodiment of the invention, 2-3 layer strips(2) is wound between the tread (S) and the steel belt (K) as single strip package or single layer strips (2) is wound as 2-3 layers. The self-sealing strip (2) layer located on the top is wound as strips such that it will have 0-5° degrees with the equatorial plane. The width of the self-sealing strip layer (2), also the width of the self-sealing cap strip package (1), may be smaller or bigger than or equal to the width of the steel belt layer at the bottom._The width of the self- sealing strip layer (2) applied by being wound side to side in strips can vary 8mm to 25mm. In the preferred embodiment of the invention, the width of the self- sealing strip layer (2) is 8- 10mm.
The total thickness of the cap strip package (1) which is formed by bringing the self- sealing strip layers (2) on top of each other or winding them can vary between 1 and 5 mm. In the preferred embodiment of the invention, the said thickness is l,5-2,5mm.
The cords (3) are manufactured from polymeric material; in the preferred embodiment of the invention, it may be comprised of any material selected from nylon 6.6, nylon 4.6, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and aramide or aramide-nylon, aramide-PET, PET-nylon hybrid materials. The linear densities of cords (3) can vary between 400- 5000dtex. Total count of ends is between 30-120epdm (ends per decimeter).
The polymeric filling material (4) comprises at least one of the plastic polymeric (41) and elastic polymeric materials (42). In the preferred embodiment of the invention, un vulcanized latex and tackiness enhancing agent is used as plastic material (41), and vulcanized latex is used as elastic material (42). The said materials (41, 42) are present within the filling material (4) as layers. In one embodiment of the invention, carbon black and/or silica based reinforcement filling materials (fillers) are used between 0-10% by weight inside the elastomeric filling material (4). In one embodiment of the invention, the filling material (4) is comprised of only plastic material (Figure 1). In another embodiment of the invention, plastic and elastic materials (41, 42) are located inside the filling material (4) one on top of the other as layers (Figure 2). In a further embodiment of the present invention, the elastic material (42) forms the top and bottom of the self- sealing strip layer (2) as a layer above and below the plastic material (41), the plastic material (41) being in the middle (Figure 3).
In one embodiment of the invention, the self- sealing cap strip package (1) is comprised of two layers of self-sealing strips (2) prepared by using only plastic polymer as filling material (4) (Figure 5).
