| 中文摘要: |
| 概述负重轮天然橡胶基复合材料生热的基本原理及表征,重点介绍交联结构、填料种类及用量、偶联剂改性后白炭黑、新型碳材料氧化石墨烯和多壁碳纳米管对橡胶复合材料生热影响的研究状况。指出将新型碳材料部分取代炭黑,采用胶乳共沉淀母胶法可以将新型碳材料均一分散在橡胶中,结合机械共混加入炭黑,能有效提高天然橡胶复合材料的强度同时降低其生热。新型碳材料制备成本高,需要进一步探讨新型碳材料放量制备的简易方法及分散工艺,以开发能够成熟地进行工业化生产,应用于负重轮的高强度低生热的天然橡胶复合材料。 |
| 英文摘要: |
| The basic mechanism and characterization of heat build-up of natural rubber （NR）-based composites for loadwheel were summarized in this paper，and the research status of the influence of
crosslinking structure and filler（including carbon black，modified silica by silane coupling agent，new carbon
material such as graphene oxide and multi-wall carbon nanotubes） on the heat build-up of the composites
was mainly introduced. It was pointed out that partial replacement of carbon black by new carbon materials
and preparation of new carbon material masterbatch by the latex co-precipitation method were conducive
to uniformly dispersing the new carbon materials in NR-based composite materials，effectively improving
the strength of NR-based composite materials while reducing its heat build-up. The production cost of new
carbon material was high，so it was necessary to further explore simple methods for large scale production
and dispersing process of new carbon materials to develop NR-based composites with high strength and low
heat build-up which could be industrially produced and applied to loadwheel. |
