The Function And Classification Of Antioxidant And Light Stabilizer.Triphenyl Phosphite (TPPI)
Antioxidant And Light Stabilizer, The Role And Functions, Plastic Materials Due To The Different Molecular Structure, Or With The Molecular Structure Due To The Different Polymerization Process, Different Processing Technology, The Use Of The Environment And Conditions Different, Their Thermal Oxidation, Light Oxidation Reaction Rate And Thermal Oxidation, Photo Oxidation Reaction Capacity Have Very Different. Antioxidants And Light Stabilizers Are Added In Plastic Materials, And Effectively Suppress Or Reduce The Thermal Oxidation Of Plastic Molecules, Photo Oxidation Reaction Rate, Significantly Improve The Heat Of Plastic Materials, Light Performance, Slow Down The Degradation Of Plastic Materials, The Aging Process And Extend The Use Life Of Plastic Additives, Plastic Products.The Function And Classification Of Antioxidant And Light Stabilizer.Triphenyl Phosphite (TPPI)
The Function And Classification Of Antioxidant And Light Stabilizer
Antioxidant Antioxidant Is The Most Widely Used In Plastics Additives. One Of The Most Widely Used In Plastic Polymerization Synthesis, Granulation, Storage, Processing, Use Of Different Stages And Has Antioxidant Application. The Most Widely Used The Second Component Is That In Today'S World Has Appeared On A Variety Of Different Molecular Structure Types Of Plastic Materials, Such As Polyethylene, Polypropylene, Styrene Polymer, Engineering Plastics, Plastic And Other Materials, The Application Of Antioxidant Types Of Plastic Materials Most.

1. As Synthetic Rubber And Resin Stabilizer, Antioxidant And Raw Materials PVC Alkyd Resin And Pesticide Intermediates. As The Cellulose Resin, Vinyl Resin, Natural Rubber And Synthetic Rubber Flame Retardant Plasticizer. This Product Is Of Low Volatility, High Flame Retardant Efficiency, With Excellent Mechanical Property Retention, Transparency, Flexibility And Toughness. Mainly Used For Nitrocellulose, Cellulose Acetate Film (E.G., Film Base) And A Flame-Retardant Plasticizer Plastic Film, Can Also Be Used In Viscose Fiber As Camphor Nonflammable Substitutes.
2. As Polyethylene, Polypropylene, Polyvinyl Chloride, ABS Resin, Epoxy Resin, Synthetic Rubber And Polyester Polymers Antioxidant Stabilizer. Halogen Flame Retardants And Use, Can Play Its Fire-Retardant And Antioxidant Effect, And Having A Light Stabilization. Also Widely Used In PVC Chelator, When A Metal Soap-Based Stabilizers, Together With The Product Can Reduce The Harm Of Metal Chlorides, And To Maintain The Transparency Of Products And Inhibit Change Chromaticity.
Commonly Used Plastic Antioxidant According To Their Molecular Structure And Mechanism Of Action Are Generally Classified Into Four Categories: Hindered Phenol, Phosphite Esters, Thio And Compound. Hindered Phenolic Antioxidant Is Plastic Materials Of The Main Antioxidant, Its Main Role Is With Plastic Materials Due To Oxidation Of Free Radical Oxidation Of The R - And Roo - Reaction, Interrupt Activity Chain Growth. According To The Molecular Structure Of Hindered Phenolic Antioxidants Into Single Phenol, Bisphenol A, Polyphenols, Heterocyclic Polyphenols And Other Varieties. Single Phenol And Bisphenol Antioxidants, Such As BHT, 2246 And Other Products, Because Of The Low Molecular Weight, Volatile And Migration Of Large, Easy To Make Coloured Plastics Products, In Recent Years In Plastics Consumption Is Greatly Reduced. Polyphenol Antioxidant 1010 And 1076 Is Dominant Product Today, Foreign And Domestic Of Antioxidants For Plastics, 1010 With Molecular Weight High, With Plastic Material Compatibility Good, Excellent Antioxidant Effect, Consumption Maximum As Antioxidants For Plastics In The Best Products. 1010 And 1076 Of Domestic Production And Consumption Accounted For About 60% Of The Total Domestic Production Of Antioxidant Consumption.The Function And Classification Of Antioxidant And Light Stabilizer.Triphenyl Phosphite (TPPI)
Phosphite Antioxidant And Sulfur-Containing Antioxidant As Auxiliary Antioxidant. The Main Mechanism Of Auxiliary Antioxidant Is Through Changes In Its Molecular Phosphorus Or Sulfur Atom Valence, The Plastic In The High Activity Of Hydrogen Peroxide Is Decomposed Into Low Molecular Activity. The Domestic Production Of Phosphite Antioxidant Consumption Accounts For About 30% Of The Total Domestic Production Of Antioxidant Consumption. Domestic Production Of Sulfur-Containing Antioxidants In Molecular Structure Can Be Divided Into Three Types: Thio Ester Antioxidant, Thio Bisphenol Antioxidant And Sulfide Type Phenol. Different Types Of Main And Auxiliary Antioxidants, Or The Same Type Of Different Molecular Structure Of Antioxidants, Function And Application Effect Of The Differences, Strengths And Weaknesses. Antioxidant Compound By Two Or More Than Two Kinds Of Different Types With Different Varieties Of Antioxidant Compound, In Plastic Materials Can Complement Each Other, Showing A Synergistic Effect, With Minimal Added Amount, And The Minimum Cost And Achieve The Best Thermal Oxygen Aging Effect. Synergistic Effect Refers To The Use Of Two Or More Than Two Kinds Of Additives, The Effect Is Greater Than The Effect Of The Use Of Each Agent Alone And The Effect, That Is, 1+1 > 2. The Composite Antioxidant And Light Stabilizer Compound, Antioxidant And Light Stabilizer Compound Synergistic Effect, Can Greatly Enhance The Antioxidant And Light Stabilizer Anti-Aging Effect. The More Common Phosphite Antioxidant Is Triphenyl Phosphite, Phosphorous Acid Triphenyl Ester Antioxidant, Stabilizer Tppi) Is Mainly Used In Polyvinyl Chloride, Polyethylene, Polypropylene, Polystyrene, Polyester, ABS Tree Ester, Epoxy Resin, Synthetic Rubber And Other Antioxidant Stabilizer, Used In PVC Products For The Chelator.The Function And Classification Of Antioxidant And Light Stabilizer.Triphenyl Phosphite (TPPI)
In The Fifties Of The 20th Century In China, Developed A Single Phenol Hindered Phenolic Antioxidant BHT And Sixties Developed Thio Ester Antioxidant DLTDP Or Dstdp, 1970s Developed Polyphenol Hindered Phenol Antioxidant 1010 And 1076. In The 1980s Developed Phosphite Antioxidant 168 And Composite Antioxidant 215, 225 And So On. In 1982 The National Production Of Plastic Antioxidants Total Consumption Of Less Than 1000 Tons. In 2002, Domestic Plastic Production Of Antioxidant Consumption Has More Than 20000 Tons, Close To The United States And Western Europe In The 20th Century In The Late Eighties Of The Consumption Quantity. Domestic Of Antioxidants For Plastics Products And The Quality Of Products, Able To Basically Meet The Needs Of The Domestic Petrochemical And Plastic Industry. The Main Antioxidant Varieties Each Year Exports.
