Abstract
The invention discloses a kind of resistance to dynamic ozone aging sidewall rubbers, the characteristics of being stretched and be easy by ozone aging by flexion for a long time according to tire sidewall, in versatility rubber natural rubber, butadiene rubber, on the basis of butadiene-styrene rubber, the resistance to preferable chlorosulfonated polyethylene rubber of ozone ability is added, the resistance to preferable anti-aging agent 6PPD of the dynamic ozone aging and preferable antioxidant D TPD of suitable resistance to static ozone aging, ultraviolet absorbing agent UV-0 is added in sizing material, product ultraviolet absorbing agent UV-0 cooperation in rubber and chlorosulfonated polyethylene rubber is preferable, while in order to further increase the ozone-resistant aging property of the tire sidewall glue and reduce the cost of sizing material, it joined the high-tenacity butyl with significant ozone-resistant aging property and restore glue.
Description
Technical field
The present invention relates to a kind of tire sealants, and in particular to a kind of resistance to dynamic ozone aging tire sidewall glue and its preparation side
Method belongs to rubber processing techniques field.
Background technique
Ozone is exactly to crack to the erosion results for the rubber product that application centainly strains, these crackles eventually result in
The thorough failure of rubber product.Unlike other rubber products, it bears strength constantly and is constantly moving tire, and takes turns
Tire sidewall rubber is relatively thin, continual by flexion stretching action in motion process, so the present risen year by year in ozone content
It, it is easy to is by dynamic ozone aging.
The prior art is that a large amount of ozone-resistant anti-aging agent is added in tire sidewall glue, and operation in this way easilys lead to tire
During ozone and aging resistance, there is anti-aging agent and tire sidewall surface, especially rubber antioxidant protection wax is precipitated, energy is precipitated
Power is strong, causes tire sidewall to lose original color, influences Appcarance guality of tyres, so cannot go simply to guarantee sidewall
Ozone and aging resistance go that the anti-aging agent of resistance to ozone is largely added.
Summary of the invention
Place to overcome above-mentioned the deficiencies in the prior art, the present invention provides a kind of resistance to dynamic ozone aging tire sidewalls
Glue, it is natural in versatility rubber the characteristics of being stretched and be easy by ozone aging by flexion for a long time according to tire sidewall
On the basis of butadiene-styrene rubber, it is smelly that the preferable chlorosulfonated polyethylene rubber of resistance to ozone ability, resistance to dynamic is added in rubber, butadiene rubber
The preferable anti-aging agent 6PPD of oxygen aging and the preferable antioxidant D TPD of suitable resistance to static ozone aging, two kinds of anti-aging agents are taken
With keeping the aging effect of resistance to dynamic ozone of sizing material more preferable, and cooperate a small amount of protection wax and anti-aging agent TMQ and resistance to ozone ability
Preferably, the high-tenacity butyl that intensity is higher and price is lower restores glue, and rubber is under ultraviolet irradiation, the speed of ozone aging
Degree can more faster, and tellurian uitraviolet intensity is also gradually increasing at present, special thus that ultraviolet light is added in sizing material
Absorbent UV-0, the product ultraviolet absorbing agent UV-0 cooperation in rubber and chlorosulfonated polyethylene rubber preferably, have significant
Ageing-resistant performance.
The present invention is achieved through the following technical solutions: a kind of resistance to dynamic ozone aging tire sidewall glue, feature exist

Part；UV-0,1.5-2 parts of ultraviolet absorbing agent；N660 carbon black, 30 parts；N330 carbon black, 30 parts；High-tenacity butyl restores glue, 8-10
Part.
The preparation method of the resistance to dynamic ozone aging tire sidewall glue, it is characterised in that:
The preparation of step 1) masterbatch: use X (S) M-1.5L mixer, rotor speed 40r/min, hybrid technique and its add
Material sequence are as follows: natural rubber, butadiene rubber, butadiene-styrene rubber, high-tenacity butyl restore glue, chlorosulfonated polyethylene rubber, anti-aging agent
6PPD, anti-aging agent TMQ, zinc oxide, SA, antioxidant D TPD, protection wax, ultraviolet absorbing agent UV-0 → pressure floating weight (40s) →
N660 carbon black, N330 carbon black → pressure floating weight (100s) → aromatic naphtha, Petropols → pressure floating weight (70s) → dumping, dumping
127 DEG C of temperature；
The preparation of step 2 finished composition: XK-160 open mill, charging sequence are as follows: masterbatch → accelerator NS, sulphur → glue are used
Expect uniformly mixed, thin logical → sizing material slice.
Advantageous effects of the present invention: resistance to dynamic ozone aging tire sidewall glue prepared by the present invention has ageing-resistant performance
Excellent, inexpensive, after 6 months test phases, tire sidewall no cracking, also there is no point types to be cracked.
Specific embodiment
Below with reference to embodiment, the present invention will be further described.
