Preferably, described antioxidant is the mixture of propionic acid carbon alcohol ester oxidation inhibitor and sulfo-alkoxide oxidation inhibitor.Preferably, both mass ratios are 1:1 ~ 2:1, preferred, 25:18.
Preferably, described sulfo-alkoxide oxidation inhibitor is one or more in the two octadecyl of thio-2 acid, the two lauryl alcohol ester of thio-2 acid, the two tridecanol ester of thio-2 acid, the two tetradecyl alcohol ester of thio-2 acid.
Preferably, described propionic acid carbon alcohol ester oxidation inhibitor is the positive octadecanol ester of propionic acid.
Preferably, described photostabilizer is benzophenone ultraviolet absorption agent.
Preferably, described benzophenone ultraviolet absorption agent is one or more in ESCALOL 567, Octabenzone and 2-hydroxyl-4-dodecyloxy benzophenones.
Preferably, described peroxide cross-linking agent is tert-butyl peroxide class superoxide.
Preferably, described tert-butyl peroxide class superoxide is ditertiary butyl peroxide, tertbutyl peroxide.
Preferably, described additional crosslinker is oximes or methyl methacrylate.
Preferably, described oximes is the one in paraquinonedioxime, dibenzoyl paraquinonedioxime.
Relative to prior art, material for anti-aging peroxide-crosslinked polyethylene pipe of the present invention has following advantage: the crosslinked polyethylene pipe using material produce of the present invention, and its degree of crosslinking is high, crosslinked good stability, degraded probability is low, and the consumption of linking agent is few.Add a kind of composite anti-aging, resisting ultraviolet radiation formula, ensure that it is anti-aging, resisting ultraviolet radiation ability; Extend its work-ing life, expand its use range; For its large-area applications, provide safety control.
