Abstract
Official abstract text for this publication.
The present disclosure relates to a low noise tire, and more specifically, to a low noise tire that includes: a sealant layer adhered to an inside surface of an inner liner of the tire; and a sound-absorbing material layer adhered to the sealant layer, in which the sound-absorbing material layer includes 50 to 90 wt % of a polypropylene melt-blown fiber and 10 to 50 wt % of a polymer fiber.
First claim
Opening claim text (preview).
What is claimed is: 1. A low noise tire comprising: a sealant layer adhered to an inside surface of an inner liner of a tire; and a sound-absorbing material layer adhered to the sealant layer, wherein the sound-absorbing material layer comprises 50 to 90 wt % of a polypropylene melt-blown fiber and 10 to 50 wt % of a polymer fiber. 2. The low noise tire of claim 1 , wherein the sealant layer comprises 20 to 40 wt % of a butyl rubber, 20 to 30 wt % of polybutene, and 35 to 50 wt % of a filler. 3. The low noise tire of claim 2 , wherein the filler is one or more selected from the group consisting of carbon black, silica, mica, magnesium hydroxide, aluminum hydroxide, aluminum silicate, magnesium silicate, barium sulfate, calcium carbonate, talc, and clay. 4. The low noise tire of claim 1 , wherein the sealant layer has a thickness of 0.1 to 10 mm. 5. The low noise tire of claim 1 , wherein the polypropylene melt-blown fiber has a diameter of 0.1 to 10 μm. 6. The low noise tire of claim 1 , wherein the polymer fiber is one or more selected from the group consisting of a polyethylene fiber, a polyester fiber, a polyethylene terephthalate fiber, a polybutylene terephthalate fiber, a polyamide fiber, a polyurethane fiber, a polylactic acid fiber, a polyvinyl alcohol fiber, a polyacrylonitrile fiber, and a polyphenylene sulfide fiber. 7. The low noise tire of claim 1 , wherein the polymer fiber has a diameter of 1 to 10 μm. 8. The low noise tire of claim 1 , wherein the sound-absorbing material layer has a thickness of 1 to 50 mm.
