This study employed a high-speed rotating crushing process to modify pyrolyzed carbon black (CBp) using self-lubricating and low-friction polytetrafluoroethylene (PTFE). The effects of PTFE content on the dispersion, mechanical properties, wear resistance, thermal stability modified PTFE-CBp/natural rubber (NR) composites were investigated. from grinder altered physical structure PTFE, forming tiny fibrous structures that interspersed among CBp particles. arrangement encouraged alignment...
Abstract Prolonged operations of mixers cause wear mixer rotors and chamber walls affect the clearances between walls, which reduce mixing effect, weaken dispersion packing, quality rubber products. In this study, effects traditional wet on friction chamber, properties were compared by using 60 phr a silica natural formulation system. The results show that silanization reaction occurs silane coupling agent during process rate is fastest when temperature maintained 145 155°C for 1 min...
Abstract Studies show that the mixing process is one of most critical steps in rubber processing, which directly affects performance and service life products. However, unjustifiable complexity, high processing time, low quality conventional technologies restrict development industry. Aiming at deficiency technology present, wet continuous are complementary to each other, developed. Then experiments carried out evaluate proposed method. The obtained experimental results have synergetic...
Spent Fluid Catalytic Cracking (FCC) Catalyst is a major waste in the field of petroleum processing field, with large output and serious pollution. The treatment cost these catalysts high, how to achieve their efficient reuse has become key topic research at home abroad. To this end, paper conducted mechanistic experimental study on replacement some carbon blacks by spent FCC for preparation rubber products explored synergistic reinforcing effect blacks, order extend methods reduce pollution...
Abstract The drying process of natural rubber latex significantly affects the structure raw network and vulcanizate crosslinking network, resulting in various anti‐aging performances. In present study, a microwave generator was used as an efficient source clean energy; potassium oleate introduced foaming agent to increase porosity water loss channel system. Aiming at dehydrating efficiently, aging resistant composite prepared. Meanwhile, mechanism agent‐assisted on cross‐linking studied....
Abstract Using sodium thiosulfate and hydrochloric acid as the raw materials a silica aqueous dispersion carrier, sulfur is generated in situ by chemical precipitation method, an sulfur‐silica/natural rubber (in S‐Silica/NR) composite prepared. The characterized, its effects on natural composites' cross‐linking density, vulcanization characteristics, mechanical properties, aging dynamic Payne effect are studied. experimental results show that particle size of small, with maximum 5 μm,...
Abstract This study proposes that the foaming pre‐dispersion technology is combined with gas‐phase‐assisted spray technology, and a agent potassium oleate introduced. The volume expansion power generated by bubbles promotes dispersion of filler. uniformity chemical bridging between rubber silica. Then, large velocity difference compressed air emulsion, gun refines emulsion breaks filler aggregates. Next, atomized droplets splash on surface high‐temperature roller, then deposit it to achieve...
Abstract This paper prepared potassium oleate/silica/natural rubber composites by atomization spray drying technology. study compared the effects of environmental protection accelerator oleate and amine 1,3‐diphenylguanidine on Payne effect, silane reaction index, vulcanization performance, mechanical properties, static dynamic aging properties silica/natural rubber. The results show that can promote increase reaction's efficiency. When formed silica coating, carboxyl group hydroxyl were...
The Thermochemical method (pyrolysis) is the most promising means to treat waste plastics, which can be converted into high value-added products with significant economic and social benefits. In this study, pyrolysis characteristics synergistic effects of mixed plastics under different atmospheres (nitrogen carbon dioxide) were explored, various kinetic models used calculate parameters. experimental results demonstrate that dioxide atmosphere beneficial reduce onset temperature activation...
