用反向沉淀法制备酶解木质素/氢氧化镁复合材料，并研究其对丁苯橡胶（SBR）胶料的阻燃效应。结果表明：复合材料中酶解木质素包覆氧化镁，酶解木质素/氢氧化镁并用比为1∶1时，复合材料的阻燃效应较好，800℃时的质量保持率高；100份复合材料（酶解木质素/氢氧化镁并用比1∶1）的与10份微胶囊红磷配合的SBR胶料燃烧成炭性好，阻燃级别可达到FV-0，阻燃性能和物理性能好。
用反嚮沉澱法製備酶解木質素/氫氧化鎂複閤材料，併研究其對丁苯橡膠（SBR）膠料的阻燃效應。結果錶明：複閤材料中酶解木質素包覆氧化鎂，酶解木質素/氫氧化鎂併用比為1∶1時，複閤材料的阻燃效應較好，800℃時的質量保持率高；100份複閤材料（酶解木質素/氫氧化鎂併用比1∶1）的與10份微膠囊紅燐配閤的SBR膠料燃燒成炭性好，阻燃級彆可達到FV-0，阻燃性能和物理性能好。

The enzymatic hydrolysis lignin/magnesium hydroxide composites were prepared by reverse precipitation method and its effect on the flame retardant property of SBR compound was investigated. In the composites, the enzymatic hydrolysis lignin was coated on the surface of magnesium hydroxide. When the ratio of enzymatic hydrolysis lignin/magnesium hydroxide was 1∶1, the flame retardant property of the composite was good and the mass retention at 800 oC was high. With this ratio, when 100 phr of the composites and 10 phr of microencapsulated red phosphorus were jointly applied in SBR, the compound could form a charcoal layer when subjected to ifre, and the lfame retardant rating reached FV-0 level, while the physical properties of the SBR compound were also good.
