APAO - Uses and synthesis methods
application
ethylene propylene copolymer is a synthetic polymer material with a wide range of uses. Ethylene propylene rubber with ethylene content less than 5% (weight) is a modified variety of isotactic polypropylene (iPP), the trade name is PPR, which has better toughness and transparency than iPP, and can be used to make pipes and other iPP incompetent A series of application fields. Ethylene propylene rubber (EPR) with ethylene content between 20 and 50% has the properties of elastomer and has been widely used as a plastic toughening modifier. Mixing an appropriate amount of EPR into iPP can obtain a modified polypropylene material with much higher impact resistance than ordinary iPP, which is used in many fields such as automobile bumpers and impact injection molded products.
structure and performance
Those made only by the copolymerization of ethylene and propylene are called ethylene-propylene rubber. If non-conjugated diene is added as the third monomer, it is called EPDM rubber. The main chain of ethylene-propylene rubber molecules is saturated structure, does not contain double bonds, and the ethylene and propylene units are randomly distributed, which makes it have excellent ozone resistance, atmospheric aging resistance, chemical corrosion resistance, high temperature resistance and electrical properties. When processed into rubber products, EPDM rubber can be vulcanized by traditional sulfur vulcanization process, but EPDM rubber can only be vulcanized with free-based vulcanizing agents such as peroxide due to lack of double bonds. Ethylene propylene rubber products can be used for automotive parts (such as door and window belts, sidewalls, heat-bearing parts), heat-resistant conveyor belts, hoses, linings, wires and cables, and building waterproof materials. The disadvantages of ethylene propylene rubber are poor compatibility with other rubbers and poor wet and slippery resistance.
use
1, used for crude oil dehydration, refinery demulsification and desalination. It can also be used as dispersant, defoamer, levelling agent and metal extractant.
2, used to make various gaskets, hoses, tapes, etc.
production method
1 mol of propylene glycol and 0.5% of solid NaOH were added to the pressure kettle. After replacing the air in the kettle with nitrogen, the temperature is increased to 120 ℃ under stirring until NaOH dissolves. The introduction of ethylene oxide m mol, the introduction speed to control the reaction temperature of 120 ℃ is appropriate. After the reaction is completed, n mol of propylene oxide is introduced at a temperature of 120 ℃. After the reaction is completed, cool and adjust the pH value to 7±1 with phosphoric acid. Press filter to remove inorganic salts. Use solvent to adjust the filtrate to the required specifications. Such as BP-169,BP-121, BP-2040,
