Crosslinking of saturated elastomers with diazides
In this paper diazides are presented as alternatives to peroxide vulcanization systems, particularly in combination with the use of plasticizing oils. The performance of three diazides; tri...
The Mechanism of Phenolic Resin Vulcanization of Unsaturated
The basic curing resins used are generally 2,6-dihydroxymethyl-4-alkylphenols 1 or their condensation polymers 2 (Scheme 1). These materials are produced via the base-catalyzed reaction of the p -substituted phenol with formaldehyde. R is typically methyl, t -butyl, or t -octyl in commercial resins.
- Can bio-based phenol functionalized liquid rubber be used as rubber plasticizer?
- 4. Conclusions The bio-based phenol functionalized liquid rubber by the olefin metathesis reaction of high molecular weight 1,2-PB and bio-based phenols, which can be used as rubber plasticizer to greatly improve the compatibility of rubber and silica, resulting in excellent performances of vulcanizates.
- Which plasticizer is used for silica filled styrene-butadiene rubber (SBR)?
- The 1,2-PB- g-CA was used as a plasticizer for silica filled styrene-butadiene rubber (SBR). The enhanced interfacial interaction between phenolic hydroxyl groups of cardanol and the silanol groups of silica significantly increased the compatibility of silica and rubber matrix.
- Can functional liquid rubber be used as a plasticizer?
- To study the effect of the synthesized functional liquid rubber as a plasticizer, 1,2-PB- g -CA (Mn = 1.5 × 10 4 g/mol, Fn = 11.34) was blended with paraffinic oil by a certain proportion. As shown in Fig. 6, when adding carbon black and plasticizer at 115 °C, the mixing torque and the mixing temperature increased instantaneously.
- What are the advantages of vulcanizate based plasticizer?
- The vulcanizates also exhibited better rolling resistance, wet grip, low temperature build-up, and tensile properties. Compared with paraffinic oil, the prepared cardanol based plasticizer has excellent anti-migration properties because it can be co-crosslinked with rubber matrix, being more green and environmentally friendly.
- Does plasticized SBR reduce filler aggregation in vulcanizates?
- The bound rubber content indicates a stronger interaction between rubber and silica in 1,2-PB- g -CA plasticized SBR. This result confirms that 1,2-PB- g -CA is a perfect material for processing aid by reducing filler aggregation and oil migration in vulcanizates.
- Can bio-based products be used in rubber additives?
- In addition, the present method can also be applied to other rubber products containing 1,2-polybutadiene structures, such as styrene-butadiene rubber, nitrile-butadiene rubber, etc., which provides new methods and ideas for the application of bio-based products in rubber additives.
