New antioxidant
The development of new antioxidants is environmentally friendly. In order to meet the requirements of polymer processing and application, new anti-oxidant development has new characteristics in recent years due to the increasingly strict environmental protection and safety regulations.
Antioxidant besides consumption due to volatile, in under the action of light, heat and other spoiled or react with chemicals, in the process of products using the migration and solvent extract and deadweight loss, which reduces the efficiency of antioxidants. For this purpose, we hope to develop a new type of antioxidant, which can be polymerized with monomers and become part of the polymer, thus solving the defects such as volatilization, extraction and migration of antioxidant agents.
At present, the existing reactive antioxidants have NDPA and DENA, as well as TAP, DAC and DBA, all of which belong to phenolic compounds containing allyl.
Polymer quantitative persistence, efficiency is measured stabilizer comprehensive performance of the two aspects, the increasing of molecular weight is helpful to reduce the wip in the volatile, take out and migration losses, at the same time reduce the phenomenon such as products of fog, and sweating. But not the bigger the molecular weight, the better, because of oxidation occurs mainly in the products surface, when the surface antioxidant was consumed, the inside of the products whether antioxidants can migrate to the surface in time become the key to effective, so the relative molecular mass of the antioxidant usually under 1500.
At present, the most widely used antioxidant BHT has better processing stability than efficient Irganox1010, but its molecular weight is low and it is very easy to volatilize and dissipate.
Sasaki et al. Synthesis of antioxidant GA - 80 structure is relatively complex, high relative molecular mass of the antioxidant, has a good antioxidant effect, the hydrolysis resistance is strong, and low volatile, has been widely used.
Clean and specialty antioxidants are mostly powder goods, as people to the requirement of increasing the working environment, aggregate type antioxidant began to appear, this not only improved the working environment of workers, also makes people can accurately measuring the amount of antioxidants, and antioxidants in polymer distribution more uniform, helps to improve the overall stability of the product.
Triphenyl phosphite (antioxidant, stabilizer TPPi)
Packing method: net weight of 200KG/galvanized iron bucket (a small cabinet to hold 16 tons), 1000KG/IB (a small container with 18 tons) or 23 tons of it.
Port of shipment: Shanghai port
Price quotation validity: 15 days
Warehouse time: within 15 days (customs clearance)
Export rights: our own right to import and export.
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.
A new type of liquid antioxidant used to improve the polymerization efficiency of rubber and PVC (PVC). The new high performance liquid antioxidant has a low melting point, which is mainly used in synthetic rubber, especially polybutylene rubber (BR) and styrene butadiene rubber (SBR). The terminal application mainly includes tires, shoes, gloves, conveyor belts and other rubber products. It is reported that this additive can improve the color stability and Mooney viscosity of raw rubber. Because of its low melting point, it also helps to reduce the difficulty of processing.
An antioxidant used in the polymer industry. This antioxidant is a 2, 6-dit-butyl-4-methylphenol compound, which is not polluting, and is suitable for mixing plastics, resins and rubber, as well as various mineral and plant hydrocarbons and oils. This antioxidant product is crystalline powder insoluble in water, with purity not less than 98%, and 5% soluble in light oil.
The research direction of antioxidant has shifted to the development of highly efficient and versatile auxiliaries and reactive antioxidant agents.
Antioxidant butylated hydroxytoluene and synthetic rubber (nitrile, polyurethane, butyl benzene, butadiene, etc.), polyethylene, PVC stabilizer, antioxidant phenolic antioxidant butylated hydroxytoluene is commonly used in rubber, antioxidant butylated hydroxytoluene of natural rubber, butadiene, styrene butadiene, butyl, isoamyl, nitrile, synthetic rubber, such as ethylene propylene acrylate and latex products hot oxygen aging has protective effect, antioxidant butylated hydroxytoluene can inhibit copper, with the ozone resistance and wax and can prevent climate of various factors on the analysis of the damage, it is easily dispersed in rubber antioxidant butylated hydroxytoluene directly mixed with rubber or as dispersions in latex, can be used in the manufacture of the sidewall of the tire, white, bright color and transparent color of various rubber and dairy products and daily, health care, tape, rubber shoes and grocery rubber products, antioxidant butylated hydroxytoluene also can be used as a stabilizer of synthetic rubber processing and storage.
At present, the production and YingShi antioxidants more than 50 kinds of varieties, mainly include butylated hydroxytoluene, 1010, 1076, 168, DLTP, 2246, 4226, 3114, 246, DSTDP, etc., in 2006 the total production capacity of about 50 kt/a.
The consumption structure was roughly 60% of the total consumption of the blocked phenol, about 27% of the phosphoesters, about 7% of thioesters, and about 6% of the others. In our country, the antioxidant industry has also developed many new varieties with excellent performance, such as high hydrolysis stability and high heat resistance of bisphenol phosphite. The high effective calcium salt antioxidant 1425 was found in the higher molecular weight. In the chemical crosslinked cable, the antioxidant 1010 is substituted for the antioxidant 1035.
