The invention discloses a processing method of an all-steel radial tire. The processing method of the all-steel radial tire comprises the following steps of pre-vulcanizing a lining layer shoulder rubber sheet and a lining layer ring rubber sheet, winding the rubber sheets, calendering a transition layer rubber sheet, calendering an inner liner rubber sheet, compounding the transition layer rubbersheet with the inner liner rubber sheet, compounding the compounded rubber sheets with the pre-vulcanized lining layer shoulder rubber sheet and the pre-vulcanized lining layer ring rubber sheet, andcarcass shaping. By applying the processing method of the all-steel radial tire, the size stability of the rubber material at the key part of an lining layer is ensured, the problem of the rubber material migration at the key part of the tire is effectively solved, the offset of the curvature of a tire body is reduced to be within 6mm from the original 20mm, therefore, the occurrence rate of diseases such as empty shoulders and empty rings is effectively reduced, the durability of the tire is improved, meanwhile, the thickness of the lining layer is reduced, and the tire is lighter in weight,economical and environment-friendly. The invention further provides the all-steel radial tire which is manufactured and formed through the processing method.

    本申请公开了一种全钢子午胎的加工方法,包括预硫化内衬层肩部胶片和内衬层圈部胶片,收卷胶片,压延过渡层胶片,压延气密层胶片,将过渡层胶片与气密层胶片复合,将复合后的胶片与预硫化的内衬层肩部胶片和内衬层圈部胶片复合,胎体成型。应用本申请全钢子午胎的加工方法保证了内衬层关键部位胶料尺寸的稳定性,有效解决了轮胎关键部位的胶料迁移问题,使轮胎胎体弯曲度的偏移量降低,可由原来的偏移20mm降低到6mm以内,从而有效降低肩空圈空等病象的发生率,提高轮胎的耐久性能,同时也使内衬层厚度降低,使轮胎更加轻量化,经济环保。本申请还提供了一种全钢子午胎,其采用上述加工方法制作成型。
