Peroxide decomposed antioxidant
Peroxide decomposition type antioxidant is the main variety of metal (such as copper, zinc, molybdenum and antimony etc.) alkyl thiophosphate compounds and amino acid compounds have certain antioxidant capacity, peroxide decomposition type antioxidant used in engine oil, mainly anti-wear, antifriction, anti oxygen and extreme pressure.
In particular, two alkyl two thiophosphate (ZDDP) products have good corrosion resistance, anti-wear resistance and extreme pressure resistance. Since the advent of peroxide decomposition type antioxidant, has been launched a major group of oil and oil industry indispensable, it can effectively prevent the corrosion of engine bearing, can inhibit the oil viscosity caused by high temperature oxidation growth in lubricating oil additive plays an important role in.
The antioxidant properties of different ZDDP (T202, T203, T204 and T205) in the base oil were investigated by SH/T0193 (0.25%).
It can be seen that ZDDP series of antioxidant and anti-corrosion agents have good antioxidant activities in 125N base oil, and the antioxidant effect of T204 in HVIW H150 base oil is better. In synthetic oil PAO6, ZDDP series antioxidants have good antioxidant effects. There are many kinds of antioxidants in organic copper salts, including copper salts of organic carboxylic acids, copper thiophosphate, copper thioformate, copper sulfide, and so on.
Such as two alkyl two thiophosphate antioxidant has good high temperature oxidation resistance. It is a lubricating oil antioxidant with low dose and high temperature oxidation resistance.
It can effectively control the oil viscosity due to oxidation of growth, and high temperature detergent and ashless dispersant has good compatibility, is an important additive modulation and high grade internal combustion engine oil. Organic copper salts can eliminate active alkyl radicals and peroxyl radicals, but copper ions also play a catalytic role in the decomposition of hydroperoxide to some extent. Therefore, the application of such antioxidants is still controversial.
Organic molybdenum compounds are an important class of peroxide antioxidant, and can also effectively reduce the friction factor of oil products. Such as two two ISO octyl phosphorothioate molybdenum is an oil soluble lubricating oil additive, antiwear and friction reduction effect is remarkable, it is the main group of internal combustion engine running in oil efficient modulation; can also be used in gear oil, hydraulic oil, crankcase oil and metal processing oil, to reduce friction and wear the role of.
Triphenyl phosphite (TPPi antioxidants, stabilizer) is mainly used in PVC, polyethylene, polypropylene, polystyrene, polyester, abs resin, epoxy resin, synthetic rubber antioxidant stabilizer, used in polyvinyl chloride (PVC) products as a chelating agent.
Cas no. : 101-02-0
HS: 29209019.00
The most important index of products: colorless, yellow liquid
Density (rho) 2525:1.183-1.192, refractive index (eta 020) : 1.585 1.590, freezing point ° C: 19-24, chloride (Cl - %) : 0.20 or less
Tax refund: the current tax refund of Triphenyl phosphite is 9 percent
Raw materials: phenol, phosphorus trichloride, phosphorus trichloride.
In recent years, fuel economy has become an international hot issue. Reducing friction and improving oxidation resistance is obviously reflected in the new generation of oil products in Europe and America.
Such as molybdenum dialkyldithiocarbamate antioxidant has excellent antifriction property, can help the new energy-saving internal combustion engine by bench test specification; molybdenum ammonia complex with good oxidation resistance and excellent antifriction performance, Shigeki Matsui with long chain alkyl complex 0.02% (molybdenum molybdenum ammonia mass fraction) modulation of a lubricating oil friction the factor is low, the wear scar diameter is small, very good detergency. The lubricating oil formulations containing molybdenum ammonia complex in 1.5% of the soot case, the determination of detergency was 10 (the maximum).
Researchers also introduced a molybdenum ammonia complex with excellent friction reducing performance. Its friction coefficient in oil is lower than that of two alkyl two molybdenum thiocarbamate.
Some people add it to fuel oil, so as to improve the oxidation resistance and storage stability of fuel oil. Alkyl thiocarbamates are used as lubricating oil antioxidants, mainly including two alkyl, two thiocarbamate zinc, two alkyl two thiocarbamate, two alkyl two thiocarbamate antimony, two alkyl two, thiocarbamate cadmium and so on. Such as two alkyl two thiocarbamate is a kind of multi effect additive, in high temperature conditions, the antioxidant effect is especially prominent.
Two alkyl two thiocarbamate has good antioxidation properties, and has good antifriction and corrosion resistance. In addition, no metal containing two alkyl two thiocarbamate is an ashless antioxidant important peroxide decomposition, and phenols, free radical scavenger and antioxidant compound with amine to good effect, can effectively suppress the oil due to the formation of high temperature oxidation caused by the viscosity increase, can also control the sludge.
Two together with two alkyl dithiocarbamates with many additives have a strong synergistic effect, can improve the efficiency of other additives, not easy to lose activity under high temperature conditions; at the same time has good extreme pressure effect at high concentration, can partially replace ZDDP. The mass fraction of the antioxidant used as an antioxidant was 0.1% to 1%, and the mass fraction was 2% ~ 4% when used as an extreme pressure agent. It is mainly applied to turbine oil, hydraulic oil, gear oil and internal combustion engine oil, which can improve the oxidation resistance and wear resistance of oil products, and increase the load of Timken OK in lubricating grease.
