synthesis and properties of a novel reactive and low,the addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. however, antioxidant migration can cause environmental pollution. to address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (gma) and p-aminodiphenylamine (ppda). the
various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.

this work provides a unique source of inspiration for the preparation of low-cost, highly effective clcds from plant biomass waste, most of lignin being used to produce steam and energy, with excellent antioxidant capability for rubber, which is beneficial for a green and sustainable world.
accelerators and antioxidants in the rubber industry,however, the knowledge gradually reached other rubber chemists and started them on a search for other and better accelerators. the first u. s. patents on accelerators were issued in 1915 to hofrnann and gottlob, and on this basis the claim was made (and accepted for a time) that
(pdf) rubber antioxidants and their transformation products
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation...
recent progress in the rubber antioxidants Rubber Auxiliary Agent,the anti-aging behavior of styrene-butadiene rubber (sbr)/silica with cos-gmmp, as well as the low molecule antioxidant gm, was systematically investigated by the accelerated thermal aging...

in this study, we chose natural rubber (nr) as a matrix and provided a screening strategy based on diverse natural phenolic antioxidants to evaluate their ability in protecting nr composites. thymol, a-tocopherol, and lipid-soluble epigallocatechin gallate (lsegcg) were chosen from 18 natural phenolic antioxidants as potential alternative
rubber antioxidants and chemical 6ppd,amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.

- Can antioxidants prevent rubber aging?
- The addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. However, antioxidant migration can cause environmental pollution. To address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (GMA) and p -aminodiphenylamine (PPDA).
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- What is thermo-oxidative aging of rubber?
- This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers. The oxidative degradation of rubber proceeds by a free-radical chain reaction mechanism . As shown in Fig. 1a, rubber aging processes have three distinct phases: (i) Initiation, (ii) Propagation, and
- What are the different types of antioxidants in rubber?
- Chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (NBC)) antioxidants according to their chemical structure (Figure 1). During the rubber production, various antioxidants are often used as a mixture to improve performance and ensure an antiaging effect.
