The invention discloses a preparation method of an oil-resistant cable sheath material, which comprises the following steps: compounding 45-67 parts by weight of chloroprene rubber and 8-23 parts by weight of polyvinyl chloride in a Banbury mixer, keeping the temperature, and cooling to room temperature; adding 12-20 parts of decabromodiphenyl oxide, 1-9 parts of ethylene thiourea, 5-15 parts of benzoperoxide, 8-21 parts of aluminum hydroxide, 1-13 parts of dioctyl epoxytetrahydrophthalate and 4-17 parts of polyvinyl butyral, compounding for 3-5 minutes adding 3-14 parts of lubricant and 3-16 parts of antioxidant 1010, and compounding for 2-4 minutes; and carrying out thin passing in an open mill, and extruding through a double screw extruder. The cable sheath material has the advantages of higher volume resistivity, higher vertical burning grade and higher oil resistance. The method has the advantages of simple preparation technique and reasonable time and temperature control settings, and can be widely used in industrial production.

A kind of method that benzyl peroxide is prepared by toluene liquid-phase air oxidation method
ActiveCN106831521BGuaranteed oxygen contentAchieve the purpose of obtainingOrganic compound preparationOrganic-compounds/hydrides/coordination-complexes catalystsToluene oxidationReaction temperature
The invention discloses a method for preparing benzyl peroxide by adopting a toluene liquid-phase air oxidation method. Under the synergistic effect of a catalyst, an initiator and an assistant, toluene and oxygen in the air perform oxidizing reaction to generate the benzyl peroxide, the balance of reaction temperature is ensured by adopting an external circulated cooling mode, pressure balance in a toluene oxidation reactor is controlled according to the discharge amount of high-temperature compressed tail gas or nitrogen or reaction tail gas led from the upper portion of the reactor, the reaction process is full-automatically controlled, and safe, stable and continuous reaction is ensured. The oxygen content in the reaction tail gas is ensured by controlling the high-temperature compressed tail gas or nitrogen led from the lower portion of the reactor and reaction conditions, and higher toluene conversion rate is ensured. The product benzyl peroxide can serve as a raw production material of benzene-alcohol, aromatic aldehyde, aromatic acid and benzyl ester, and the method is a green and environment-friendly no-chloride involved process.
