Description
The present invention is entitled：Electric wire and cable jacket material oxidation induction period and content of carbon black test device, the applying date are：
On 05 26th, 2014, Application No.：201410224862.2 application for a patent for invention divisional application.
Technical field
The invention belongs to electric wire and cable material inspection technology field, is induced more particularly, to electric wire and cable jacket material oxidation
Phase and content of carbon black test device and method of testing.
Background technology
Air and sunlight are essential to tellurian human survival and plant growth, but this makes to polyolefine material
Severe destruction is but played during.The ultraviolet in oxygen and sunlight in air causes plastic material that hot oxygen occurs
Change or photooxidation reaction, the physical and mechanical properties for being used in photoelectricity cable jacket and the polyolefine material of insulation are deteriorated, lost in advance
Remove original function and use value.Plastic material is because molecular structure is different, or with molecular structure because polymerization technique is different, processing work
Skill is different, use environment is different with condition, thermal oxide, photooxidation reaction speed and thermal oxidation resistance, the photooxidation reaction energy of itself
Power is very different.Antioxidant and light stabilizer make an addition in plastic material the heat that can effectively suppress or reduce plastics macromolecular
Oxidation, photooxidation reaction speed, significantly increase heat-resisting, the light fastness of plastic material, delay degraded, the aging of plastic material
Process, extend plastic products service life.But because supplier in order to reduce cost uses regenerated plastics, or antioxidant and light
Stabilizer addition deficiency and poor performance cause polyolefine material antioxygenic property in natural environment to be deteriorated, and reduce photoelectricity cable
Mechanical and physical performance and service life, so as to which all trades and professions are caused with larger harm.Therefore the thermal oxide of test material is stable
Performance is extremely important, and to the oxidation induction period of material be exactly reflect material thermo oxidative stability can an important indicator,
The service life of product, the quality of the performance of raw material are differentiated by the test of oxidation induction period.Oxidation induction period method be
By accelerating the aging of catalysis material come the hot oxygen life-span for material of extrapolating under high temperature pure oxygen, it is considered that, if oxidation induction period
For one minute, the service life of product was 1 year.For cable or optical cable, service life typically requires to be not less than 20 years；
Therefore, the People's Republic of China every household standard GB/T15065-2009《Electric wire black polyethylene plastic》In define it is black
Color ESCR low density polyethylene (LDPE) protective cover material（NDH）, black LLDPE protective cover material（LDH）, it is close in black
Spend polyethylene sheath material（MH）, black high density polyethylene (HDPE) protective cover material（GH）Oxidation induction period must be not less than 30min, so
And due to the continuous aggravation of competition, in the market occurs a variety of using electric wire and cable jacket material made of recycled plastic, this material
Expect using less than in 5 years there have been serious sheath cracking, deformation, premature ageing, reduce the service life of cable, be
This, user side's demand is compared strict test to oxidation induction period.
Electric wire has indoor and outdoor application differentiation, and the cable for outdoor is typically to be exposed to air and sun
In light, due to having substantial amounts of ultraviolet in sunlight, the aging for sheath has acceleration, therefore, if in cable material
Without appropriate antiultraviolet composition, then cable is unable to reach expected life, in industry, is typically employed in sheath material and adds
Add the mode of carbon black to realize.The filling of carbon black in the plastic does not embody significant enhancing effect, but can improve its resistance to thermal change
Shape performance, dimensional stability, rigidity and hardness etc..With the increase of black loading, its tensile strength and impact property are anxious
Play declines, and according to carbon black, its different loading of role is different in the plastic.When requiring that carbon black plays stable and anti-aging
When, its addition is the 2~3% of the weight of plastics；Carbon black in cable jacket material also acts simultaneously to sheath material
The effect of color.Therefore, in order that electric wire has preferable uvioresistant effect and appropriate deformability, stability, just
Degree and hardness, the content of carbon black in cable jacket material is examined to be even more important.
The content of the invention
In order to solve the above problems, the purpose of the present invention is to disclose a kind of test device, and it can both be used for testing electric wire
The oxidation induction period of cable sheath material, the content of carbon black tested in electric wire and cable jacket material can be used for again, it is to use

One end is connected on the temperature input interface of tester；The tubular unit is made of clear material；The cork
On glass airway tube is installed in another connecting hole for having；The thermocouple assembly is copper thermocouple assembly or platinum thermocouple
Component；Described electric wire and cable jacket material oxidation induction period test device test electric wire and cable jacket material oxidation induction period
Method, comprise the steps of：First power taking line cable jacket material is some, inserts the holding in thing unit of combustion boat, combustion boat is put into
In the cavity of quartz ampoule, and centre position is placed on as far as possible, then by cork plug in the cavity of quartz ampoule one end；In tester
Set temperature value is 200 DEG C on device, and nitrogen is accessed to the air inlet of second solenoid valve by pipeline, oxygen is accessed by pipeline
The air inlet of first magnetic valve, second solenoid valve is opened, and the air inflow of nitrogen is controlled by tester, open the first electromagnetism
Valve, and it is zero to control the air inflow of oxygen by tester, is heated ring shaped heating mechanism, tester passes through thermoelectricity
The thermometric end of even component monitors heating-up temperature when being setting value, closes second solenoid valve and cuts off nitrogen supply (NS) and simultaneously further beats
As the flow that the first magnetic valve is driven when making supply for oxygen and oxygen flow with for nitrogen and start timing, and be labeled as first
Time, the temperature in quartz ampoule is in the stable state for rising and becoming steady, dashed forward when there is temperature on the display screen of tester
It was labeled as the second time when so rapidly rising, now stops the heating of ring shaped heating mechanism and being passed through for oxygen；Second time with
The difference of the very first time is oxidation induction period；Another connecting hole on cork serve it is ventilative, make inside quartz ampoule
The effect of pressure remained steady.
