Abstract: Epoxy asphalt is a kind of modified asphalt material obtained by curing reaction of matrix
asphalt, epoxy resin and curing agent. It is widely used as pavement material for long-span bridge deck
and heavy haul traffic pavement due to its excellent fatigue resistance and adhesion. In this paper, the
composition, structure and performance characteristics of epoxy asphalt are described, and the research
progress in toughening modification and compatibility modification is emphatically reviewed, and the future
development direction of epoxy asphalt is prospected.
Key words: epoxy resin; bitumen; toughening; compatibility modification

炭黑企业筹建两大海外白炭黑生产基地
Carbon black enterprises prepare to build two overseas white carbon black production bases

近日，随着确成股份募投 7.5 万 t 项目的建设，其公司 2023 年预计沉淀法二氧化硅产能将达 40.5 万 t，规模
优势持续加强。确成股份也在加快全球化布局，同时重视白炭黑在附加值更高领域的应用发展。
据了解，确成股份公司泰国基地一期项目已建成投产，泰国二期项目正在筹备中，拟以自有资金建设年产 2.5
万 t 产能，欧洲生产基地建设目前正在前期尽调中，海外布局使公司能够快速响应当地客户需求，加速新客户和
新市场的拓展，有望推动海外业绩快速提升。
作为全球二氧化硅龙头企业。确成股份长期专注于沉淀法二氧化硅的生产和销售。截至 2022 年三季度，确
成股份沉淀法二氧化硅产能规模达 33 万 t，位列国内第一位和世界第三位。
近几年随着国内外高性能轮胎的研发和市场的需求度的增加，二氧化硅白炭黑的市场需求度大增，同时，海
外二氧化硅巨头扩产进度放缓，索尔维等龙头企业在近三年内没有新增产能，国内沉淀法二氧化硅新建产能受到
政策限制，扩产难度增大。另外，受益于汽车市场复苏和轮胎生产绿色化趋势，轮胎领域对沉淀法二氧化硅形成
强劲支撑，下游市场景气度持续回暖。
确成股份也在加强新产品研发技术储备，促进整体产品布局更加系列化、精细化、高端化。
