Antioxygen 1024 test piece for cable material and evaluation experimental method thereof

Abstract

The invention discloses an antioxygen 1024 test piece for a cable material and an evaluation experimental method thereof. The test piece is of a ''sandwich '' structure or a ''coating '' structure composed of a sample piece and a copper foil, the sample piece is made of LDPE resin pellets matching with different antioxygen materials, and the sample piece is prepared from the following in parts byweight: 100 parts of the LDPE resin pellets, 0.1-0.2 part of antioxygen 1010, 0.1-0.2 part of antioxygen DLTP and 0.2-0.6 part of antioxygen 1024; and the test piece with the ''sandwich '' structure is suspended in a constant temperature and humidity test box with the temperature of 50 DEG C and the humidity of 80% and is taken out for observation after 48 h, and the test piece with the ''coating'' structure is placed into a constant temperature oven with the temperature of 90 DEG C to be baked for 144 h and then taken out for observation. According to the antioxygen 1024 test piece for the cable material and the evaluation experimental method thereof, the requirements of cable material manufactures for raw material incoming evaluation are met, the experimental cost is slow, operation is easy, the effect is intuitive visible, and it is convenient for operating personnel to make decisions.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to an antioxidant 1024 test piece for cable materials and an evaluation experiment method thereof. Background technique [0002] Antioxidant and anti-copper agent 1024, chemical name N,N'-bis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine, has two functional groups of hindered phenol and hydrazide , wherein the hydrazide structure can complex copper ions, making it lose the destructive effect of copper ions on catalytic aging, and the effect is good. With the development of the cable industry, the amount of anti-oxidant and anti-copper agents is also increasing year by year. [0003] In the prior art, the evaluation of the anti-oxidation and anti-copper agent 1024 is mostly carried out from the aspects of volatile matter, ash, melting point, purity, etc. In these evaluation methods, the purity index monitored by HPLC is the most critical, but the equipm...

Problems solved by technology

[0003] In the prior art, the evaluation of the anti-oxidation and anti-copper agent 1024 is mostly carried out from the aspects of volatile matter, ash, melting point, purity, etc. In these evaluation methods, the purity index monitored by HPLC is the most critical, but the equipment is expensive and has a great impact on the operation. There are high requirements for personnel, which is not conducive to the cost control of the manufacturer and is not easy to observe
