High-crown tire cushion

Abstract

The utility model relates to the technical field of auxiliary material for tire manufacturing, and specifically relates to a high-rigidity tire cushion cloth, which comprises a base cloth layer and a coating layer, wherein the base cloth layer is a three-layer composite structure comprising a middle high-rigidity layer and symmetrical flexible transition layers on both sides of the middle high-rigidity layer; the coating layer comprises a first coating layer and a second coating layer, which respectively cover the outer surfaces of the flexible transition layers on both sides; the middle high-rigidity layer is composed of high-modulus polyester filaments and aramid fibers, and the weaving structure is plain weave or basket weave; the flexible transition layer is one of viscose non-woven fabric or low-density nylon mesh cloth. The utility model provides core rigidity through the middle high-rigidity layer (high-modulus polyester + aramid), and the flexible transition layers (viscose non-woven fabric / low-density nylon mesh cloth) on both sides enhance flexibility, thereby solving the problem that the rigidity and flexibility of traditional single-layer cushion cloth are difficult to balance, and avoiding delamination or fracture caused by local excessive rigidity during tire molding.
