To reduce the impact of road ice and snow disaster, it is necessary to adopt low energy consumption and efficient active deicing and snow melting methods. In this article, three functional components are combined into a conductive ethylene propylene diene monomer (EPDM) rubber composite material with good interface bonding. Among them, the mechanical and electrical properties of the composite material are enhanced by using carbon fiber cloth as a heating layer. EPDM rubber plays a mainly protective role. Further, aluminum silicate fiber cloth is used as a thermal insulation layer. The mechanical properties of EPDM rubber composites reinforced by carbon fiber cloth and the thermal behaviors of the composite material in high and low temperature environments were studied. The heat generation and heat transfer effect of the composite were analyzed by electrothermal tests. The results show that the conductive EPDM rubber composite material has good temperature durability, outstanding mechanical stability, and excellent heat production capacity. The feasibility of the material for road active deicing and snow melting is verified. It is a kind of electric heating deicing material with broad application prospects.

For the better mechanical and thermal properties of polypropylene (PP), PP sea-island structured composites with elastomer ethylene-propylene-diene monomer (EPDM) and coal powder were prepared by melt-blending method. Coupling agent γ-methacryloxypropyltrimethoxysilane (KH-570) was used as modifier to improve the superficial capacity of coal powder. The structural changes and properties of modified coal powder and composites were characterized and analyzed by Fourier Transform Infrared Spectroscopy (FTIR), surface contact angle analysis, scanning electron microscope (SEM), thermogravimetric analysis (TGA) and mechanical testing. Results show that the modified coal powder has good hydrophobicity and sea-island structure is beneficial in improving the comprehensive performance of composites. The contact angle increases from 33.8° to 91.6° after modification. The initial decomposition temperature (T0) and largest weight loss temperature (Tmd) both have an increase with coal powder content and the maximum are 431.02 °C and 465.33 °C. The mechanical properties tend to go up first and then down with the addition of coal powder. PP/26EPDM/4coal composite has best mechanical properties as well as the impact strength and elongation at break are 60.9 MPa, 615.0%, respectively.

Thermoplastic elastomer (TPE), made from ethylene propylene diene monomer (EPDM) and poly-propylene (PP) based on reactive blending, has an excellent processing performance and characteristics and a wide range of applications. However, there are currently no reports in the literature regarding the usage of TPE in making composite boards. In this paper, EPDM, PP, and ammonium lignosulfonate (AL) were used as the raw materials, poly-ethylene wax was used as the plasticizer, and a dicumyl peroxide vulcanization system with dynamic vulcanization was used to make a new kind of composite material. This research studied the influences of the AL contents on the crystallization behaviors, rheological properties, thermal properties, and mechanical properties of the composites. The results showed that the AL content had a noticeable impact on the performance of the composite board. Accordingly, this kind of composite material can be used as an elastomer material for the core layer of laminated flooring.
