一种高耐寒抗拉型锚固钉
摘要：
本发明公开了一种高耐寒抗拉型锚固钉，包括：螺丝以及固定在所述螺丝表面的涨管，所述螺丝包括母体以及电镀在所述母体外表面的锌镍合金层，所述锌镍合金层中各元素的质量配比为：所述镍的含量为16-24%，所述锌的含量为76-84%，所述涨管由尼龙塑料和天然橡胶高温融合而成，按照质量百分比计算，所述尼龙塑料的含量占68-78%，所述天然橡胶的含量占22-32%，通过上述方式，本发明能够具备有超强的耐寒性能，防止产品在天气寒冷的时候发生收缩，导致紧固效果下降，同时还能具备有良好的抗拉强度，提高使用寿命。
摘要（英）：

The invention discloses an anchoring nail with high cold resistance and tensile strength. The anchoring nail comprises a screw and an expansion pipe fixed to the surface of the screw, wherein the screw comprises a matrix body and a zinc-nickel alloy layer electroplated on the outer surface of the matrix body, and the zinc-nickel alloy layer contains, by mass, 16-24% of nickel and 76-84% of zinc; the expansion pipe is formed by high-temperature fusion of nylon plastic and natural rubber and contains, by mass, 68-78% of nylon plastic and 22-32% of natural rubber. In this way, ultrahigh cold resistance is realized, and reduction of fastening effect caused by shrinkage of a product in cold weather is prevented; meanwhile, tensile strength is high, and service life is prolonged.
