Abstract: The freezing adhesive characteristics of 6 kinds of engineering materials such as Q235, PTFE, aluminum alloy, rubber, smooth glass and frosted glass were tested by using the selfdesigned measuring instrument of freezing adhesive force. The concept of freezing adhesive coefficient of materials was defined and the freezing adhesive coefficients of abovementioned materials were obtained from the freezing adhesive tests. The interface damage morphology between material and ice was observed, the damage behavior of interfacial ice layer was analyzed under different freezing adhesive strengths. Freezing adhesive interface model composed of adhesive ice layer and iceadhered layer was established, and assumed that the material freezing adhesive strength is determined by the strength of the adhesive ice layer itself. The mechanism of generating freezing adhesive strength was analyzed, providing a new approach to the research of antifreezing adhesive theory and techniques.
