SBR耐老化性能的研究 摘要：本论文是研究硫化体系、防护体系、增塑体系和补强体系对SBR耐老化性能的影响。通过改变硫化剂的用量，防老剂的品种及防老剂并用，增塑剂和补强剂的用量；来研究SBR的力学性能以及老化后的力学性能保持率。通过实验分析发现：当硫黄为1.5份时，SBR胶料的力学性能和老化后的力学性能的保持率均较好；防老剂RD和防老剂A并用时会出现协同效应，有利于丁苯橡胶老化的防护；炭黑N330为50份及机油3份时，SBR胶料老化后的力学性能保持率相对较好。 关键词：丁苯橡胶；耐老化性能；防护体系 Anti-aging properties of SBR Abstract：This paper is to study the curing system, protection system, plasticizer and reinforcing system on anti-aging properties of SBR. By changing the amount of curing agent, antioxidants and antioxidant species and use, the amount of plasticizer and reinforcing agents; to study the mechanical properties of SBR and the mechanical properties after aging retention. Through experiment we found: When the sulfur 1.5 phr, SBR rubber mechanical properties and mechanical properties after aging to maintain good rates; antioxidant RD and antioxidants A and will appear with a synergistic effect, beneficial to SBR aging protection; carbon black N330, 50 parts and oil 3 phr, SBR rubber to keep the aging rate after the relatively good mechanical properties Key Words：SBR；Aging performance；Protection system 目录 摘 要…………………………………..........................................................................Ⅰ Abstract ................................................................................................................................Ⅱ 1 前言…………………………………………………………………………………….1 1.1 SBR概述 …………………………………………………………………………...1 1.2 硫化体系概述 ………………………………………………………………………2 1.2.1 橡胶硫化的发展概况……………………………………………………………...2 1.2.2 硫黄硫化…………………………………………………………………………...3 1.3 防护体系概述………………………………………………………………………..4 1.3.1 橡胶防护的历史与研究进展……………………………………………………...5 1.3.2 防老剂的作用机理………………………………………………………………...6 1.4 补强填充体系概述…………………………………………………………………..7 1.4.1 补强与填充的发展历史…………………………………………………………...8 1.4.2 炭黑概述…………………………………………………………………………...8 1.5 增塑体系概述………………………………………………………………………..9 1.5.1 橡胶增塑机理……………………………………………………………………...10 1.6 本论文的研究目的和内容……………………………………………………………11 2 试验部分……………………………………………………………………………….12 2.1 试验原料…………………………………………………………………
