Description
技术领域
本发明涉及聚酰胺树脂组合物及含有该组合物的中空成形体。
背景技术
以下对聚酰胺树脂的称呼是基于JIS K6920-1。
聚酰胺12(PA12)在制成成形体时,由于柔软性、耐破坏压力性、低温冲击耐受性、环境耐受性及耐化学试剂性优异,制造成形体时的成形性和加工性也良好,因此作为以汽车用管等中空成形体用途为代表的产业用聚酰胺树脂被广泛使用。
发明内容
发明要解决的课题
另一方面,近年来,出于以下的主要原因,PA12需求的紧迫化逐渐变得常态化。
(1)以中国为首的新兴国家对PA12的需求在国际上增大;
(2)作为PA12原料单体的丁二烯由于也是汽车轮胎等橡胶制品的原料,因此丁二烯的需求也很紧迫。
本发明的课题在于提供具有与PA12至少为同等水平的柔软性、耐破坏压力性、低温冲击耐受性、环境耐受性及耐化学试剂性、制造成形体时的成形性和加工性也良好的组合物及使用了该组合物的中空成形体。

(本发明的中空成形体)
本发明的中空成形体具有将本发明的聚酰胺树脂组合物进行成形而成的层1。
但是,这里在将本发明的聚酰胺树脂组合物进行中空成形而制成层1时,当配合有除该聚酰胺树脂组合物中所含的成分以外的树脂和/或添加剂等时,在配合后的树脂组合物相当于本发明中规定的聚酰胺树脂组合物的情况下,将配合后的树脂组合物视作聚酰胺树脂组合物。
本发明的中空成形体可以用在通过中空成形来成形的部件或制品、例如燃料罐、如石油罐、油罐、其他的罐;农药瓶、饮料水用瓶等各种瓶;空气导管、进气歧管等各种机械及汽车的吸气、排气系部件;空气扰流器、挡泥板、保险杠等汽车外板/外装结构构件等用途中。另外,作为中空成形部件,可举出染料输送管、节气阀体、共鸣器、空气过滤器盒、悬吊保护罩、进气歧管、空气过滤器、共鸣器、燃油分配管、软管连接头、油压管、空压管、燃料管、油压软管、空压软管、燃料软管。
本发明的中空成形体即便仅由层1构成,也具有与使用PA12的单一层的中空成形体同等的实用性能。
本发明的中空成形体从成形加工时的稳定性及耐环境性的观点出发,优选进一步具有将含有聚酰胺树脂的树脂组合物进行成形而成的层2,且层1与所述层2相接触地层叠,此时从成形加工时的稳定性、耐环境性及外观的观点出发,更优选层1是中空成形体的最内层。
本发明的中空成形体另一方面从成形加工时的稳定性及耐环境性的观点出发,优选进一步具有将含有聚酰胺树脂的树脂组合物进行成形而成的层3及4,且层1、3及4相接触地层叠,而且层1不是所述中空成形体的最外层、最内层中的任一者。
层1、3及4相接触地层叠是指只要是它们全部直接地接触,则层1、3及4可以以任意的组合相接触。例如可举出层1/层3/层4、层1/层4/层3或层3/层1/层4的情形。但是,为层1/层3/层4及层1/层4/层3时,优选层1不是所述中空成形体的最外层、最内层中的任一者,若层1是内层侧,则优选按照层1不会变为最内层的方式来实施与层1接触的层叠。
进而,从成形加工时的稳定性及低温冲击性的观点出发,优选上述层3及4含有聚酰胺11和/或聚酰胺12。
从减少PA12的含有率的观点出发,以上的中空成形体的层1的合计厚度优选为中空成形体的层叠整体的厚度的15~100%、更优选为中空成形体的层叠整体的厚度的50~100%、进一步优选为中空成形体的层叠整体的厚度的70~100%。
但是,当各层是由不同组成的本发明聚酰胺树脂组合物构成时,由于这些各层均是组成不同的层1,因此层1的厚度就变成这些各层的厚度的合计。
本发明的中空成形体还可以使用例如挤出成形机、吹塑成形机、压缩成形机、注塑成形机等将本发明的聚酰胺树脂组合物成形为膜状、片材状、管状、软管状等各种形状,膜状、片材状者还可进行后加工制成中空成形物。层叠方法采用以共挤出成形法(T-口模挤出、膨胀挤出、吹塑成形、异型挤出、挤出涂覆等)、层叠注塑成形法为代表的任意的熔融成形法。
作为制造多层管或层叠软管的方法,例如可举出以下方法:将利用对应于所构成的层的数量或者对应于材料的数量的挤出机所挤出的熔融树脂导入到1个模具中、在模具内使各层粘接或者离开模具后立即使各层粘接、之后与通常的管成形或软管成形同样地进行制造的方法;以及先成形单层管或单层软管后、在该管或软管的外侧涂覆其他层的方法等。
管或软管的形状可以是直管,也可加工成蛇腹状。
对于直管的多层管或层叠软管,还可在其外侧设置保护层,作为其形成材料,例如可举出氯丁二烯橡胶、乙烯丙烯双烯三元共聚物、环氧氯丙烷橡胶、氯化聚乙烯、丙烯酸橡胶、氯磺化聚乙烯、硅橡胶等橡胶。

对于形成实施例2~3的中空成形体的层1的树脂组合物和形成比较例1~5中制造的相当于中空成形体的层1的层的树脂,利用注塑成形机制作ISO527-1Type A型的试验片。注塑条件是树脂温度为240℃(形成实施例2~3的层1的树脂组合物)、240℃(聚酰胺树脂(PA6/12))、250℃(聚酰胺树脂1(PA6))、240℃(聚酰胺树脂2(PA12))、240℃(聚酰胺树脂3(PA6/66))、220℃(粘接剂(アドマーQB520E)),通过模具温度为80℃的注塑成形进行成形,获得试验用板。
注塑成形条件是注塑压力:一次压50MPa、注塑时间:20秒、冷却时间:20秒。
在90℃的热水中将所制作的试验片处理2小时后取出,将10重量%的氯化锌水溶液滴加在试验片上。
接着,在100℃的热风循环式烘箱中将试验片干燥处理2小时后取出。
将此作为1个循环,在下述评价条件下观察试验片表面,反复进行操作直至发生断裂或者到达10个循环。
断裂发生如下确认:每1个循环中使用显微镜放大至10倍,观察试验片表面,确认在试验片表面是否发生了断裂。
将以上的结果汇总示于表1。
由表1可知,作为通过本发明的聚酰胺树脂组合物(实施例1)成形的成形体的单层(实施例2)及4层(实施例3)的中空成形体显示出了与PA12的单层的中空成形体基本同等的物性,本发明可作为近年需求紧迫的PA12的代替树脂组合物来使用。

接着,利用进行尺寸控制的整形模实施冷却、牵引,获得层的厚度为1.5mm、内径为9mm、外径为12mm的单层管。
(3)比较例6
除了在实施例4中使混合比为成分A:85重量%、成分B:0重量%、成分C:15重量%以外,在相同的条件下制造单层管。
