Abstract

The invention belongs to a nylon composite material with low temperature resistance and high temperature resistance. The nylon composite material is prepared from the following raw materials in parts by weight: 65-90 parts of nylon-66 resin, 5-20 parts of nylon-6 resin, 2-10 parts of polyolefin elastomer, 0.1-1 part of cuprous iodide, 0.1-1 part of a nucleating agent and 0.1-1 part of montan wax. The prepared nylon composite material has low temperature resistance and high temperature resistance at the same time and can be used in a long-acting manner under the condition that high temperature of 180 DEG C and low temperature of -40 DEG C are alternate.
