摘要：
Magnesium hydroxide (MH) was modified with triethoxysilane and polymethyl-vinyl silicone rubber and used to prepare flame-retardant oil-extended styrene-ethylene-butadiene-styrene (O-SEBS)-polypropylene (PP) composites. The water contact angle of modified magnesium hydroxide (MMH) reached 141 degrees; this indicated that MMH possessed excellent hydrophobic properties. The samples (1.6mm) passed the UL-94V-0 rating during vertical burning tests when the loading amount of MH or MMH was 70 wt %. This indicated the modification did not decrease the flame-retardant properties of MH. The tensile strength and elongation at break values of the MMH-O-SEBS-PP composites increased by 20.4 and 88.9%, respectively, compared with those of the MH-O-SEBS-PP composites. The modification of MH enhanced the interfacial compatibility between the flame retardant and the matrix; thus, the mechanical performance was enhanced. Moreover, MMH was scarcely extracted after water treatment for 168h at 70 degrees C. As a result, the mechanical properties and flame retardancy of the MMH-O-SEBS-PP composites were well maintained after the water treatment. The modification of the MH endowed the O-SEBS-PP composites with an excellent compatibility and water-resistant performance. (c) 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47129.
