Marking tape, method of applying and method of manufacturing the marking tape

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.

1 . A marking tape for application on pavement, comprising:
 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 conforming layer and the marking layer are at least partially contiguous and/or directly interconnected with each other;   wherein the fibrous layer is partially embedded in the conforming layer and in contact with the marking layer.   
     
     
         2 . The marking tape of  claim 1 , wherein the fibrous layer comprises a netting and/or a nonwoven. 
     
     
         3 . The marking tape of  claim 1 , wherein the fibrous layer is at least partially embedded in the adhesive layer. 
     
     
         4 . The marking tape of  claim 1 , wherein the marking tape is a temporary marking tape. 
     
     
         5 . The marking tape of  claim 1 , wherein the fibrous layer comprises a netting and a nonwoven and wherein the conforming layer is at least partially arranged between the netting and the nonwoven. 
     
     
         6 . The marking tape of  claim 1 , wherein the thermoplastic material is selected from the group consisting of a styrenic block copolymer, polyolefin, polyolefin blend, elastomeric alloy, thermoplastic polyurethane, thermoplastic copolyester, thermoplastic polyamide, or a combination thereof. 
     
     
         7 . The marking tape of  claim 1 , wherein the thermoplastic material comprises a mixture of two or more thermoplastic materials. 
     
     
         8 . The marking tape of  claim 1 , wherein the thermoplastic material comprises a mixture of two or more polyolefins. 
     
     
         9 . The marking tape of  claim 1 , wherein the marking tape has a thickness in the range 10 μm to 1000 μm. 
     
     
         10 . The marking tape of  claim 1 , wherein the marking tape, with the fibrous layer removed, has an E modulus in the range 10 to 140 N/mm 2 . 
     
     
         11 . The marking tape of  claim 1 , wherein the adhesive layer comprises a pressure sensitive adhesive selected from the group consisting of untackified natural rubber, tackified natural rubber, olefins, silicones, polyisoprene, polybutadiene, polyurethanes, styrene-isoprene-styrene, and styrene-butadiene-styrene block copolymers, styrene-ethylene-butylene-styrene, styrene-ethylene-propene-styrene, or tackified or untackified acrylic adhesives and copolymers thereof including acidic groups. 
     
     
         12 . The marking tape of  claim 1 , further comprising a multiplicity of reflective and/or retroreflective elements, optionally comprising retroreflective micro beads. 
     
     
         13 . The marking tape of  claim 1 , comprising a generally flat or a structured surface, and wherein the structured surface is formed by a multiplicity of protrusions protruding from the marking tape. 
     
     
         14 . A marking tape for application on pavement, the marking tape comprising:
 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 comprising a nonwoven and a netting layer;   wherein the conforming layer and the marking layer are at least partially contiguous and wherein the fibrous layer is at least partially embedded in the conforming layer, at least partially embedded in the marking layer, and partially embedded in the adhesive layer.   
     
     
         15 . The marking tape of  claim 1 , further comprising a netting layer at least partially embedded in the conforming layer. 
     
     
         16 . The marking tape of  claim 15 , wherein the netting layer protrudes from the conforming layer into the marking layer. 
     
     
         17 . The marking tape of  claim 14 , further comprising a fibrous layer at least partially embedded in the conforming layer. 
     
     
         18 . The marking tape of  claim 17 , wherein the fibrous layer protrudes from the conforming layer into the marking layer. 
     
     
         19 . A marking tape for application on pavement, the marking tape comprising:
 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 thermoplastic material of the conforming layer and the cross-linked material of the marking layer are at least partially contiguous;   wherein the fibrous layer is at least partially embedded in the conforming layer, in contact with the adhesive layer, and at least partially embedded in the marking layer.   
     
     
         20 . The marking tape of  claim 19 , further comprising reflective elements supported by the fibrous layer in the marking layer.
