introduction of rubber antiaging agent and its types and functions
there are anti-aging agent ndbc, anti-aging agent ndibc, anti-aging agent ndmc. all green powder. with good ozone resistance and thermal oxidation resistance, expensive (due to nickel on the earth less storage, but a wide range of uses), but also a certain toxicity, deep color, easy to spray frost, not suitable for light color rubber products, in the rubber industry consumption is very few.
recent progress in the rubber antioxidants price,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 [1]. as shown in fig. This product is combustible, when storing and transporting, always pay attention to fireproof and damp proof.
synergistic effects of antioxidant 4010na ippd
although there are a variety of industrial antioxidants on the market at present, n, n′-substituted p-phenylenediamines are one of the most widely used as antioxidants in rubber industry [28].some studies about anti-oxidation activity of n, n′-substituted p-phenylenediamines have been reported, nevertheless, most of the papers evaluated their anti-oxidation activity by experimental methods.
synthesis and anti-aging property in acrylonitrile-butadiene rubber of,anti-aging properties of the antioxidants for nbr vulcanizates were evaluated by accelerated thermal aging tests and extraction resistance tests. the decomposition of vulcanizates containing dendritic antioxidants were investigated by thermogravimetric (tga) curves, and the thermo-oxidative aging kinetic parameters were calculated by the dakin-ozawa-doyle (dod) method.
facrory supply anti-aging agent, tmq, 6ppd, ippd production lead
it includes the most important type of anti-aging agent, and it is also a promising anti-aging agent. there are: anti-aging agent 4010na/ippd, anti-aging agent 4020/6ppd, anti-aging agent 4010/cppd, anti-aging agent oda, anti-aging agent dppd, anti-aging
synthesis and properties of a novel reactive and low-migration,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 product was characterized by fourier-transform.
performance characteristics of rubber additives and its application price
anti-aging agents 4010na and 4020 with excellent aging performance are especially suitable for outdoor rubber products such as wires and cables, hoses, and tapes under long-term static conditions. the main varieties of alkylaryl p-phenylenediamine antioxidants are antioxidants 4010, 4010na, 4020 and h. anti-aging agent 4020 is currently the largest amount of antioxidants used in tire rubber.

[performance] natural rubber, synthetic rubber and latex with excellent general antioxidant, excellent protective properties of ozone cracking; also the heat, oxygen, light and aging two protective agent. this product can also be used independently, but also with paraffin wax or other antioxidant and.
- Are rubber antioxidants effective against aging and antimigration?
- The antiaging and antimigration properties of the rubber antioxidants were enhanced without damaging the mechanical properties of the rubber matrix. The short-term and long-term antiaging and antimigration properties of this antioxidant are superior to those of commercially available antioxidants. CC-BY-NC-ND 4.0 . 1. Introduction
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- Does 4010na/cb/Nr composite increase thermo-oxidative aging resistance?
- The results shall indicate that, in comparison with 4010NA/CB/NR composite, there existed synergistic effect of antioxidant 4010NA and silica in 4010NA/SiO2 /NR composite on greatly enhancing thermo-oxidative aging resistance of NR material.
- Does antioxidant 4010na and silica enhance thermo-oxidative aging assistance?
- In this work, the synergistic effects of antioxidant 4010NA and silica on enhancing thermo-oxidative aging assistance for NR were investigated by experiments and molecular simulations, and the mainly conclusions were generalized as follows:
