Abstract

本发明涉及基于聚三氟乙烯的软护套，这软护套可用于卷绕挠性金属管并被用作海上软管。

Description

由PVF3制造的软护套和 其应用于软金属管
本发明涉及由PVF3制造的软护套和其应用于软金属管。
在海洋油和气开发中普遍使用软管。这些软管由软钢管、塑料套和金属套壳组成，塑料套的作用是防止油和气的泄漏。例如欧洲专利EP166385描述了这类软管。
当液体的利用温度不超过80～100℃时，聚酰胺用作为防漏热塑塑料套是合适的。
在高温下，例如高达130℃或140℃时，使用聚(1，2-二氟乙烯)。然而，由于这种聚合物是半晶质的，具有的刚性大，不可能用于这样一种结构，该结构需要盘绕和展开，有时温度很低，没有内部或外部增塑。
上述的EP166385给出了内部增塑的例子：用氟化的单体共聚合1，1-二氟乙烯。由此增加了护套的柔软度，但通常降低了其使用温度，增强了对气体的渗透性，且在急速的降压下观察到对***增强的灵敏度(对于均聚物)，使得它在高温和高压操作下使用是危险的。
FR2560884、2592655和2618791提到使用外增塑剂。在加工软管使之柔软时，某些增塑剂可使用均聚的PVDF。但是，在操作中观察到随着与PVDF极其相容的增塑剂的耗尽该护套缓慢地恢复了其原始的刚度。不仅增加了刚度而且还变脆，结果由于增塑剂的耗尽产生了内应力，护套收缩的趋势受到阻止。
人们发现通过使用包含三氟乙烯单元的聚合物克服了由于需要的PVDF内外增塑带来的所有这些缺点。本申请人发现了通过使用包含三氟乙烯单元的聚合物使制造软(挠性)护套(或管)成为可能。
由此获得的护套的使用温度比由PVDF生产的护套高很多。此外，该护套更具柔软性。
本发明护套聚合物除了三氟乙烯(VF3)之外还可包含残余的三氟氯乙烯、四氟乙烯、六氟丙烯、1，1-二氟乙烯或乙烯单元。
向本发明中添加填料、颜料或者甚至少量的酯或磺酰胺类增塑剂不脱离本发明的范围。
本发明还涉及包覆有本发明的护套的软金属管。
所获得的软管特别适用于高温下输送液态或气态烃。这种软管可再用保护层如橡胶、金属或纺织布等包覆。
对于输送气体，优选护套的聚合物主要是三氟乙烯均聚物。
本发明还涉及包覆有本发明护套的电缆。
无论是电缆还是软性管，可通过挤出法套上该护套。
电缆可以是金属丝或一股或许多股形成的金属电缆。
实施例
有一根用厚为5mm的热塑塑料护套挤出包着的挠性钢管，该钢管的直径为32mm，由多个环组成，在环之间有孔和缝隙使得管子可以活动。
为了比较不同材料构成的护套的卷曲能力，可进行下面的过程：
将加护套的管置于两个固定的支承体上。采用半径为75mm的弯曲轮在与两端支承体等距离点上施加压力。所需使套管变形和得到该轮的曲率半径的压力作用于该轮上。轮的压痕深度表明软管的变形能力。最大深度为170mm：它相当于套管在轮上完全卷绕。如果套管在完全卷绕前破裂，未记录深度。深度越大，软管越能弯曲。
此外，试验是在不同的温度下进行的。
                     实施例1
                破裂前轮的压痕深度

护套II：VF2均聚物+7.5％(重量)N-丁苯磺酰胺。
护套III：VF2和六氟丙烯按95/5摩尔比的共聚物。
护套IV：VF3均聚物。
实施例2
