High polymer plastic material antioxidant
Air and sunlight are essential for human survival and plant growth on earth, but they play a bad role in the storage, processing and use of polymer plastics. Oxygen in the air and the ultraviolet ray in sunshine plastic material thermal oxidation or light oxidation reaction, make the appearance of the plastic products and physical and mechanical properties, lose their original function and use value in advance.
This paper introduces the function and function of antioxidant agent of polymer plastics. Plastic materials because of the different molecular structure, or with the molecular structure on the basis of different polymerization process, different processing technology, the use of different environment and conditions, its heat oxidation, oxidation reaction rate and thermal oxidation, light oxidation reaction ability are quite different. Polymer is to add material antioxidant and light stabilizer for plastics in plastic material, effectively inhibit or reduce the plastic macromolecular thermal oxidation, light oxidation reaction speed, significantly improve the heat resistance, light resistance of plastic material, delay the degradation of plastic material, the aging process, prolonging the service life of the plastic products of plastic additives.
The function and classification of antioxidant and light stabilizer of polymer plastics. The antioxidants of polymer plastics are the most widely used additives in plastics. One of the most widely used contents is the application of antioxidants in the polymerization, granulation, storage, processing and use of plastics. The most widely used the content of another, is to point to in the world today there has been a different molecular structure of plastic material, such as polyethylene, polypropylene, styrene polymers, engineering plastics and modified plastics materials, application of antioxidants most kinds of plastic materials.
There are four main types of antioxidants in the molecular structure and action mechanism of polymer materials: hindered phenol, phosphatide, thiotype and composite.
The blocking phenol antioxidant is the main antioxidant of plastic materials, and its main function is the oxidation free radical R in plastic materials. And ROO? Reaction, interruption of the growth of the active chain. The inhibiting phenolic antioxidants were divided into single phenol, bisphenol, polyphenol, and nitrogen heterocyclic polyphenols by molecular structure. Monophenol and bisphenol antioxidants, such as BHT and 2246, are relatively low in molecular weight, volatile and mobile, and easy to stain plastic products. In recent years, the consumption of plastics has been greatly reduced.
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.
Polyphenols antioxidant 1010 and 1076 is the foreign and domestic plastics antioxidants leading products, 1010 with high molecular weight and good compatibility with plastic material, excellent antioxidant effect, consumption is the largest and become the most outstanding product plastic antioxidants. Domestic production consumption of 1010 and 1076 accounts for about 60% of the total domestic consumption of antioxidants.
The antioxygen and sulfur-containing antioxidants are used as auxiliary antioxidants. The main mechanism of the auxiliary antioxidant is to decompose the highly active hydrogen peroxide in the plastic into low active molecules through the change of the phosphorous or sulfur atoms in their own molecules. The production consumption of domestic phosphatide antioxidant is about 30% of the total domestic consumption of antioxidants. There are three kinds of sulfur-containing antioxidants in China, which can be divided into three kinds: thio-ester antioxidant, thio-biphenol antioxidant and thioether phenol.
Different types of main and auxiliary antioxidants, or antioxidants with different molecular structures of the same type, have different functional and application effects, each of which has its own advantages and disadvantages. Composite antioxidant by two or more than two kinds of different type or different varieties of the same type of antioxidants compound and into, can complement each other in the plastic material, shows synergistic effect, with the minimum quantity, the lowest cost and best thermal oxygen aging effect.
Synergistic effect refers to the effect of two or more additives used in compound use, which is greater than that of each auxiliary agent. The anti-aging effect of antioxidant and light stabilizer can be greatly enhanced by the synergistic effect of compound of antioxidant compound, light stabilizer, antioxidant and light stabilizer.
In China in the 1950 s developed single phenol hindered phenol antioxidant butylated hydroxytoluene, 60 s developed glucosinolates ester antioxidant DLTDP, DSTDP, developed in the seventy s polyphenols hindered phenol antioxidant 1010 and 1076, developed in the eighty s and the phosphate ester antioxidant 168 and antioxidant 215, 225, etc. In 1982, the total consumption of plastic antioxidant in China was less than 1000 tons. In 2002, the total amount of domestic plastic antioxidant production exceeded 20,000 tons, which was close to the consumption amount in the United States and Western Europe in the late 1980s. The product variety and product quality of domestic plastic antioxidant can meet the needs of domestic petrochemical and plastics industry, and the main antioxidant varieties are exported every year.
