The rubber oil optothermal stabilizer of the present invention is using a variety of hindered phenol type antioxidants, phosphite type antioxidant, arylamine
Type antioxidant and UV absorbers produce to obtain with other auxiliary materials.In 50~100 DEG C of temperature range, mainly single phenol antioxygen
Agent is worked, and the mechanism of action is that single phenol provides a hydrogen atom to alkoxy radical and captures it, the benzene oxygen radical of production
It is stabilized by steric hindrance and resonant structure.In 100~160 DEG C of temperature range, mainly polyphenol and phosphite type antioxygen
Agent, the mechanism of action are similar to single phenol.In 160 DEG C~300 DEG C of temperature range, mainly aniline type antioxidant works, and acts on machine
Reason is that aniline type antioxidant provides a hydrogen atom to alkyl diradical, alkyl peroxy radical, alkoxy radical, is generated
Aniline free radical is stablized by being dissociated into benzoquinones and alkyl nitrosobenzene class.Photostability mainly by UV absorbers and
Hindered phenol type antioxidant collective effect.
