Summary
New bio-based processing additives enhance rubber mixing and mechanical properties. Aminated epoxidized soybean oil reduces mixing energy and improves tensile strength in rubber composites.
Area of Science:
- Materials Science
- Polymer Chemistry
Background:
- Processing additives are crucial for rubber compound flowability.
- Conventional additives can negatively impact cured properties, necessitating formulation adjustments.
Purpose of the Study:
- To develop novel bio-based processing additives.
- To enhance rubber mixing and improve mechanical properties post-curing.
Main Methods:
- Substitution of petroleum-derived process oil with aminated epoxidized soybean oil.
- Evaluation of mixing energy and mechanical properties of rubber composites.
Main Results:
- A ~10% reduction in initial mixing energy was achieved.
- Aminated epoxidized soybean oil promoted rubber curing.
- Tensile strength of the final composite increased by ~20%.
Conclusions:
- Aminated epoxidized soybean oil serves as an effective bio-based processing additive.
- This additive improves both processing efficiency and final composite performance.
- Bio-based alternatives offer a promising route for sustainable rubber formulation.

01:29Additives and Fillers in Concrete
149
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.

129
Superplasticizers are advanced admixtures that enhance the workability of concrete by lowering the water content without compromising the strength of the material. These substances are highly effective water reducers, improving concrete flow, making it easier to work with, and enabling concrete to reach inaccessible areas or densely reinforced sections without mechanical vibration. The key components in superplasticizers are either sulfonated melamine or naphthalene formaldehyde condensates,...

Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

2.3K
Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.
