Tính chất điện, độ bền thời tiết của vật liệu tổ hợp LDPE/EVA/tro bay

The polymer composites based on low-density polyethylene (LDPE), ethylene vinyl acetate copolymer (EVA) and fly ash (FA) without and with organic modification were prepared by melt mixing in a Haake Rheomixer. The dielectric strength of LDPE/EVA/FA and LDPE/EVA/modified FA (MFA) composites was lower than that of LDPE/EVA blend. The LDPE/EVA/MFA composites have the dielectric strength higher than the LDPE/EVA/FA composites at the same content of FA. The weather durability of the LDPE/EVA/MFA composites is higher than that of the LDPE/EVA/FA composites and LDPE/EVA blend.
