DCBS Resistance to vulcanization


When the rubber is vulcanized at high temperature for a long time, the vulcanization phenomenon usually occurs.In fact, when vulcanization of large cross - sectional rubber products, should often pay attention to vulcanization reversion.Because in this case, the outside is affected by the high temperature for a longer time than the inside.In the other case, when a part of rubber products received a long time, the higher temperature effect, will also occur vulcanization back to the original phenomenon.Good vulcanization reversion is shown in the T90R value in the rheometer experiment, and when the torsion drops (after reaching the maximum value), it remains at the same level as that in T90. Another performance is good fixed-elongation performance.The constant elongation properties obtained under normal vulcanization conditions are comparable to those obtained under some severe vulcanization conditions, such as high temperature and/or prolonged vulcanization.CBS, TBBS, MBS, DCBS sulfur properties and physical properties, can see from the table under the condition of NR conventional vulcanization, DCBS at 150 ℃, 170 ℃ rheometer numerical best, with close to MBS tensile modulus.In addition, in 170 ℃, DCBS provides the most wide flat vulcanization line.


Viscosity is fluidity


DCBS is considered to be an excellent promoter for elastomers. DCBS has better properties than other sulfonamides.It is mainly used for steel wire rubber products and cloth rubber products.Good coking property and low vulcanization rate are the necessary conditions for vulcanization of steel wire rubber products. MBS,DIBS and DCBS can meet these conditions.The longest coking time and the lowest vulcanization rate can be obtained by using DCBS.Because MBS, DIBS can produce N- nitrosamines, only DCBS and TBSI are better.According to the data, DCBS has incomparable coke safety, and its performance is much better than TBBS. TBSI.
