Abstract
A marking tape for application on pavement which comprises a core layer and an adhesive layer outside the core layer. The core layer is formed of a combination of a conforming layer of a thermoplastic material, a marking layer of a cross-linked material, and a fibrous layer. The conforming layer and the marking layer are contiguous and/or directly interconnected with each other. The marking tape is preferably relatively light weight and relatively inexpensive.
Claims15
A method of applying a marking tape on pavement comprising the steps of:
- providing a marking tape;
- placing a portion of the tape oriented with the adhesive layer on the pavement;
- pressing the portion of the tape on the pavement while maintaining the marking tape at a temperature within a range of about 0° C. to about 50° C.,
- wherein the marking tape comprises:
- a core layer and an adhesive layer;
- wherein the adhesive layer is adapted for retaining the marking tape on the pavement;
- and
- the core layer comprises a conforming layer of a thermoplastic material, a marking layer of a cross-linked material, and a fibrous layer;
- wherein the fibrous layer comprises a nonwoven layer and a netting layer, wherein the netting layer is separate from the nonwoven layer;
- wherein the conforming layer and the marking layer are at least partially contiguous and/or directly interconnected with each other;
- wherein the nonwoven layer is partially embedded in the conforming layer and in contact with the marking layer;
- wherein the netting layer is imbedded within the conforming layer and is in contact with the adhesive layer,
- wherein the netting layer and the nonwoven layers are in contact with each other;
- wherein the conforming layer is at least partially arranged between the netting layer and the nonwoven layer.
A method of manufacturing a marking tape, comprising the steps of:
- providing thermoplastic material, a cross-linkable material, a fibrous layer formed of a nonwoven layer and/or a netting layer, and an adhesive;
- merging the thermoplastic material, the cross-linkable material, the fibrous layer, and the adhesive to form the marking tape,
- wherein the marking tape comprises:
- a core layer and an adhesive layer;
- wherein the adhesive layer is adapted for retaining the marking tape on the pavement;
- and
- the core layer comprises a conforming layer of a thermoplastic material, a marking layer of a cross-linked material, and a fibrous layer;
- wherein the fibrous layer comprises a nonwoven layer and a netting layer, wherein the netting layer is separate from the nonwoven layer;
- wherein the conforming layer and the marking layer are at least partially contiguous and/or directly interconnected with each other;
- wherein the nonwoven layer is partially embedded in the conforming layer and in contact with the marking layer;
- wherein the netting layer is imbedded within the conforming layer and is in contact with the adhesive layer,
- wherein the netting layer and the nonwoven layers are in contact with each other;
- wherein the conforming layer is at least partially arranged between the netting layer and the nonwoven layer.
