乙烯含量对EPDM硫化特性和动态力学性能的影响

通过无转子硫化仪(MDR)、橡胶加工分析仪(RPA)及力学性能测试,研究了乙烯含量对过氧化物硫化EPDM未填充体系及炭黑填充体系硫化特性及动态力学性能的影响。结果表明,对于未填充/填充体系,随着乙烯含量的增加,胶料的交联程度提高,硫化反应表观速率常数K值增大,硫化诱导时间(td)不变。相比于未填充体系,加入炭黑,在促进体系硫化速率和硫化程度的同时,硫化后期还会加剧胶料的降解程度。乙烯含量高的EPDM,拉伸强度高,炭黑-橡胶相互作用大,炭黑补强效果好,但乙烯含量对EPDM橡胶储能模量的应变依赖性没有明显影响。     

12R22.5轮胎硫化过程温度场的仿真分析

合适的硫化工艺条件是保障橡胶制品质量的重要加工因素,轮胎硫化的均匀程度直接影响其使用性能,而轮胎硫化过程中内部温度的分布对橡胶轮胎的硫化程度起着决定性的作用。因此,正确地预测硫化过程中的温度历程对轮胎生产质量和效率的提高非常重要。本来橡胶厚制品硫化(工艺)时间的确定比较复杂,对于像轮胎这样的钢丝和橡胶交替迭合的厚制品则更甚。迄今国内外橡胶厚制品

轮胎是厚制品,橡胶是不良导体,其硫化过程义与胶料的导温系数、模型几何尺寸、热介质和交换条件,以及轮胎各部件胶料的硫化特性有密切关系。轮胎在硫化机（或罐）内硫化时,模型向轮胎外表面传热,同时硫化胶囊（或水胎）向轮胎内壁传热,热量促使交联剂同橡胶产生化学交联,形成j维网状结构。

Effect of diisopropyl thiophosphoryl‐N‐oxydiethylene sulfenamide and some disulfidic compounds in the covulcanization of NR–EPDM blends

Synergistic combinations of diisopropyl thiophosphoryl‐N‐oxydiethylene sulfenamide (DIPTOS) with some disulfide accelerators or sulfur donors improve the physical properties of NR–EPDM blend vulcanizates. Various combinations of DIPTOS with dibenzothiazyl disulfide (MBTS), tetramethyl thiuram disulfide (TMTD), bis(N‐oxydiethylene) disulfide (ODDS) and bis(diisopropyl) thiophosphoryl disulfide (DIPDIS) were used in this study. DIPTOS when used alone produces NR vulcanizates with a moderate range of physical properties, whereas in conjunction with MBTS and DIPDIS it exhibits significant mutual activities. Morphological studies of the tensile‐fractured surfaces of the blend vulcanizates by scanning electron microscopy corroborate the physical data. Copyright © 2003 Society of Chemical Industry

A DSC study of curative interactions. II. The interaction of 2,2′-dibenzothiazole with ZnO,sulfur, and stearic acid

The interaction of combinations of sulfur, 2,2′-dibenzothiazole (MBTS), ZnO, and stearic acid were studied by differential scanning calorimetry. A MBTS/stearic acid interaction was indicated as evidenced by the effect the MBTS/stearic acid combination had on the melting of sulfur, the S_α → S_β transition being suppressed in favor of a S_α → S_γ transition. The dissolution/interaction of MBTS in molten sulfur was also delayed by the MBTS/stearic acid interaction, which, it is proposed, involved protonation of the N atom in MBTS by stearic acid. MBTS did not affect the formation of zinc stearate from ZnO and stearic acid, but when sulfure was added to the mixture, the ZnO/stearic acid reaction did not go to completion. No direct evidence for the formation of 2,2′-dibenzothiazole polysulphides was found, but the absence of the S_γ → S_μ transition in sulfur/MBTS mixes was interpreted as indirect evidence of a reaction between these curatives. There was no evidence for the formation of a sulfur/MBTS/ZnO compound of the type generally attributed the role of an active sulfurating agent in accelerated sulfur vulcanization.     

Bifunctional silane (TESPD) effects on improved mechanical properties of silica containing nitrile‐butadiene rubber/poly(vinyl chloride) compound

Organo bifunctional silane (TESPD) is added into silica containing NBR/PVC blend and its effects are investigated with respect to the vulcanization property, the processability, and the physical property. The addition of the TESPD into silica filled NBR/PVC compound increases the degree of crosslinking by formation of a strong three‐dimensional network structure between silica surface and rubber matrix via coupling reaction, which results in improved mechanical properties. It also improves the processability of the compound compared to the Control compound. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

Studies on Cure Synergism. II,Effect of Diisopropyl Thiophosphoryl-N-Oxydiethylene Sulfenamide and Dibenzothiazyl Disulfide in the Vulcanization of NR

Thiazole sulfenamides as well as thiocarbamyl sulfenamides in the presence of dibenzothiazyl disulfide (MBTS) form synergistic combinations of rubber accelerators that provide technologically important rubber vulcanizates. The present investigation explores the feasibility of using thiophosphoryl sulfenamide with MBTS as a binary system of mutually activated accelerators in the vulcanization of rubber. The cure characteristics of the NR compound containing various proportions of diisopropyl thiophosphoryl-N-oxydiethylene sulfenamide (DIPTOS) and MBTS have been investigated keeping the total concentrations of the accelerators at 6 mmol per 100 rubber. The results indicated mutual activity of the mixed accelerators and significant enhancement of torque, modulus, and tensile strength of the resulting vulcanizates. The general character of the reaction of thiophosphoryl sulfenamide and MBTS has been established by replacing DIPTOS by diisopropylthiophosphoryl-N-cyclopentamethylene sulfenamide (DIPTCS), in the investigation. The mutual activity consequent upon the interaction of the accelerators can be demonstrated through isolation and identification of the reaction products formed in the early part of cure using the HPLC technique, which is also extremely helpful in explaining the cure behavior of the different stocks used in the investigation. The study reveals that diisopropylthiophosphoryl-2-benzothiazole disulfide (DIBDS), formed (in situ) as a result of interaction of DIPTOS and MBTS, plays an active part in improving the physical properties of NR vulcanizates. From the chemical analyses of the vulcanizates it is evident that the network structure obtained with the binary system of accelerators is highly rich in monosulfidic linkages that render the vulcanizates resistant to aging at 100°C.
