Performance test
(1) hot strength test
Hot strength is one of most basic performance of PVC material, sample under tension effect, until fracture, sample bears
Maximum tensile stress, hot strength is big, and excellent performance is tested according to GB GB/T1040-2006.
(2) bending strength test
Bending strength test is mainly used to the inspection communication tubing performance when bearing bending load effect, conventional bending examination
Test the degree of bending property and the plastic deformation evaluating material, according to GB GB/T9341-2000.
(3) impact strength performance test
Measuring material impact intensity under the effect of shock loading, impact strength is used for evaluating material and supports shock proof ability
Or judge fragility or the degree of flexibility of material, test according to GB GB/T1843-1996.
The material of embodiment 1, embodiment 5, embodiment 6 and comparative example is carried out performance test, the result obtained such as table 7 institute
Show.
Table 7 result test table
From the result data in table 7, after organosilane crosslinked polyethylene, hot strength significantly improves, elongation at break
Declining, bending strength reduces, and impact strength improves, this is because structurally form network structure after silane polyethylene coach,
Intermolecular active force increases, and improves the mechanical property of material.
Contrast between embodiment 1,5 and 6, it is seen that the combination property of embodiment 5 is the most superior, using embodiment 5 as most preferably
Embodiment.
By in above-described embodiment, it is seen that for antioxidant, benzophenone ultraviolet absorbent selection to material
The impact of energy is little.
Therefore, for the selection of the tubing material prescription that communicates, select suitable silane and consumption the most important.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
