The invention provides low-temperature-resistant and wet-skid-resistant tread rubber for a new energy automobile and a tire of the tread rubber, and relates to the technical field of rubber composite materials. The low-temperature-resistant and wet-skid-resistant tread rubber for the new energy automobile comprises a tread layer, a supporting layer and a buffer layer, the tread layer is located on the upper layer of the supporting layer, and the buffer layer is located on the lower layer of the supporting layer; a plurality of rubber convex blocks are arranged on the tread layer, and anti-skid nails are arranged in grooves among the rubber convex blocks; each anti-skid nail comprises a nail cap, a nail body and a nail head which are connected in sequence, a fixing piece is arranged on each nail body, a plurality of steel thorns are arranged on each top cap, each nail body is embedded into the supporting layer through the corresponding fixing piece, each top cap is embedded into the supporting layer through the corresponding steel thorns, each top head penetrates out of the tread layer, and the height of the part, penetrating out of the tread layer, of each top head is smaller than that of each rubber convex block. The tire provided by the invention has low temperature resistance and wet skid resistance at the same time.

    本发明提供了一种新能源汽车用耐低温且抗湿滑胎面胶及其轮胎,涉及橡胶复合材料技术领域。新能源汽车用耐低温且抗湿滑胎面胶包括胎面层、支撑层以及缓冲层,胎面层位于支撑层的上层,缓冲层位于支撑层的下层;胎面层上开设有若干橡胶凸块,橡胶凸块之间的凹槽中设置有防滑钉;防滑钉包括依次连接的钉帽、钉身和钉头,钉身上开设有固定件,顶帽上开设有若干钢刺,钉身通过固定件嵌入支撑层中,顶帽通过钢刺嵌入支撑层中,顶头穿出胎面层,顶头穿出胎面层部分的高度小于橡胶凸块的高度。本发明轮胎能够同时兼顾抗低温性能和抗湿滑性能。
