Kind operating characteristics, and have diminishing, strengthen, prevent the good results such as be full of cracks.4, pottery: carbon content can be reduced for ceramic
Increasing green strength, reduce plastic clay consumption, slip fluidity is good, improves yield rate 70-90%.
The performance study of test example gained of the present invention one halogen-free polypropylene flame redardant CABLE MATERIALS (embodiment 5):
1, subjects
Take gained one halogen-free polypropylene flame redardant CABLE MATERIALS of the present invention and commercially available non-halogen flame-retardant cable (is purchased in Yangzhou dawn electricity
Cable limited company) carry out comparative study.
2, test method
Mechanics Performance Testing: carry out according to GB/T 528-2009；Combustibility: according to GB/T 2408-1996 standard testing water
Flat burn rate；Oxygen index (OI) is tested: carry out according to GB/T 2406.2-2009.
3, result of the test is as shown in table 1.
Table 1 CABLE MATERIALS of the present invention and the performance comparison of certain CABLE MATERIALS commercially available
As shown in Table 1, CABLE MATERIALS of the present invention is compared with commercially available CABLE MATERIALS, and its hot strength improves 35.5%, and elongation at break carries
High by 67%, show that CABLE MATERIALS mechanical property of the present invention is substantially better than commercially available non-halogen flame-retardant cable；By combustibility test data
It can be seen that non-halogen flame-retardant cable of the present invention to have the resistance to combustion time long, HRR is low, the advantage that total release heat is low,
Therefore than certain non-halogen flame-retardant cable commercially available, there is more preferable flame retardant effect.From oxygen index (OI) data, CABLE MATERIALS oxygen of the present invention refers to
Number is 32, and certain non-halogen flame-retardant cable more commercially available improves 10.3%, this be due to prescription mutually coordinated, to strengthen it fire-retardant
The effect of potentiation.
It should be pointed out that, the detailed description of the invention more representational example that is the present invention, it is clear that the skill of the present invention
Art scheme is not limited to above-described embodiment, it is also possible to have many variations.Those of ordinary skill in the art, the most public with present invention institute
What what that open or according to file written description was undoubted obtained, all it is considered as this patent scope of the claimed.
