The carbon fibers were oxidized with concentrated hydrochloric acid, and subsequently modified in two steps. First, the oxidized carbon fibers were grafted with γ‐aminopropyltriethoxysilane (KH550) with the purpose of building a platform on the fiber surface, then the epoxy functionalized elastomer (ethylene‐vinyl acetate‐glycidyl methacrylate terpolymer, EVMG) was grafted on the carbon fiber surface. Chloroprene rubber/natural rubber/carbon fiber (CR/NR/CF) composites were prepared by mechanical blending process. Carbon fibers were characterized by different techniques such as X‐ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and dynamic mechanical analysis (DMA). The results show that EVMG can enhance the interface adhesion between fiber and rubber. It was observed that the surface of the carbon fiber is covered with a layer of the macromolecular film by EVMG, which increases the surface roughness and introduces epoxy groups. On the one hand, carbon fiber and rubber can be entangled through macromolecular chains, and on the other hand, interfacial bonding can be enhanced by chemical interactions. Furthermore, modification by EVMG impacted tensile strength of CF composite increase by 11.05%, the 300% constant tensile stress increased by 21.87%, and the wear resistance increased by 29.8%, respectively.

The functionalized material ethylene vinyl acetate-glycidyl methacrylate terpolymer (EVMG) has carbon-carbon double bonds and epoxy groups [37]. Among them, the epoxy group can react with the amino group, and the carbon-carbon hydrogen bond can react with the sulfur in the rubber, which not only improves the compatibility with the rubber, but also helps to form a threedimensional crosslinked network with the rubber matrix [38,39].…”

The aim of this study is to explore a method for modifying waste brick powder (WBP) in order to reapply it to rubber products for effective resource recycling. Firstly, we use the auto polymerisation of catechol/polyamine (CPA) on the surface of WBP to form a poly catechol/polyamine (PCPA) coating as an intermediate reaction platform. And then the macromolecular modifier, epoxy-functionalized elastomer (ethylene vinyl acetate-glycidyl methacrylate terpolymer) (EVMG), is further grafted onto the PCPA coating to prepare the WBP@EVMG hybrid materials. During the preparation of the WBP@EVMG hybrid materials, a ring-opening reaction between the amine group of PCPA and the epoxy group of EVMG occurs. The NR/WBP@EVMG composites are prepared by mechanical blending. The interfacial interactions between WBP@EVMG and NR are analyzed and verified in detail by dynamic mechanical analysis (DMA) and rubber process analyzer (RPA). It is shown that the modified NR/WBP composites show increased vulcanization rate and better mechanical properties, and the tensile strength, abrasion resistance, cracking strength, and wet slip resistance of NR/WBP@EVMG-15 are increased by 29%, 6%, 16%, and 11%, respectively, compared with that of NR/WBP composites, which provides a unique idea for the reuse of waste brick powder in rubber.

In this work, we prepare epoxidized aramid pulp (AP) by grafting ethylene glycol diglycidyl ether (EGDE) onto the surface of AP via poly catechol/polyamine (PCPA). Subsequently, we premix the epoxidized AP with carboxylated nitrile butadiene rubber (XNBR) to induce a chemical reaction with the carboxyl group in XNBR. The carboxylated nitrile butadiene rubber/cis‐polybutadiene rubber/aramid pulp (XNBR/BR/AP) composites are prepared by mechanical blending. Water contact angle, FTIR, and XPS confirm the grafting of EGDE onto AP via an epoxy group ring‐opening reaction. The rheological performance results indicate that the addition of EGDE decreases the curing time of the composites and increases the degree of cross‐linking of the composites. The compatibility between AP and rubber is analyzed by SEM, and it is deduced that the interfacial bonding between AP and composite is enhanced by EGDE. The tensile strength, tear strength, abrasion resistance, and solvent resistance of the composites are significantly improved after EGDE modification. RPA results show that the modified AP is uniformly dispersed in the composites and reduces the rolling resistance of the composites. A new and effective strategy is provided for the surface functionalization of aramid pulp meal, which has a wide range of rubber industry applications.Highlights Composite mechanical properties increase with increasing EGDE content. Rheological properties of composites improved by EGDE incorporation. EGDE improves filler dispersion, reduced rolling resistance of composites. Increased interfacial bonding between AP and rubber due to EGDE.
