character: this product is deep red liquid. relative density 0.894~0.90. soluble in benzene, ether, insoluble in water. small toxic than antioxidant 4010na.
this product under static anti ozone aging effect than antioxidant 4010na, in the dynamic in the short term anti ozone aging is good, can effectively protect the flex cracking, can be directly mixed with rubber, slightly promote the scorch effect. this product is a serious pollution of antioxidant, discoloration. the general dosage is 0.7~1.5 mass.
toxicity: toxic. the ld50 of the mice was 750mg / kg. it is irritating to the skin and sometimes causes allergic reaction to the skin.
use:
as an anti ozone aging agent in natural rubber, polybutadiene rubber, styrene butadiene rubber, isoprene rubber, nitrile rubber, butyl rubber. can the general anti tear or antioxidant agent.
antioxidant 4030 is a small tonnage, anti ozone antioxidant, although the dynamic anti ozone effect is not obvious, is seldom used in the tire industry, but because of its high static ozone resistant function, in addition to the product is liquid products, easy dispersion, easy processing rubber, rubber products and rubber products used in some special environment the wire and cable, automotive applications with good market prospects.
this product is a natural rubber and synthetic rubber and effective anti ozone protection additives, static resistance to ozone aging effect is excellent, superior resistance to ozone aging antioxidant 4010na excellent performance and 4020, but in the dynamic anti ozone effect. therefore, it is especially suitable for the rubber products which are in the static state for a long time. it is suitable for long time working in static condition, such as aviation tire, engineering tire, agricultural equipment tire, vehicle structural support, fixed rubber hose, sealing strip and so on.
antioxidant 4030 can effectively prevent the rubber material is copper and other heavy metal catalytic degradation, is used in the static under long-term use of wires, cables, rubber hose, rubber belt.
antioxidant 4030 is a liquid, easy to disperse in rubber, the solubility is very high, the higher molecular weight plus than antioxidant 4010na and 4020, so even if high concentration does not appear blooming, also not easy from compound precipitation. it can be used alone in some rubber products with strict resistance to static ozone aging.
the antioxidant 4030 used in the manufacture of articles in contact with food, there is no clear provisions can be used or not. in addition of antioxidant 4030 and chlorinated paraffin and can effectively improve the performance of anti microbial compound.
the amount of antioxidant 4030 is generally 0.5-3, the compound has accelerated the scorch time and curing effect, use a large amount of no adjustment in the static vulcanization system, rubber products can be used alone, but in the dynamic, with antioxidant 4010na and 4020.
the typical use of antioxidant 4030 materials:
