摘　　要：用自制的材料冻黏力测试仪对Q235、PTFE、铝合金、橡胶、光滑玻璃和毛玻璃6种常用工程材料进行了冻黏特性试验,根据试验定义了材料冻黏系数概念并给出了上述6种材料的冻黏系数。观察了冻黏界面破坏形态,分析了在不同冻黏强度下的界面冰层的破坏规律,建立了由黏着层与黏附冰层组成的冻黏界面模型,并提出了材料的高冻黏强度主要取决于材料表面黏附冰层自身的强度的观点。分析了材料的冻黏强度机理,为冻黏防治理论与技术研究提出了新的途径。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.
