Abstract
本发明涉及一种制备低渗透性橡胶层合物的方法,其包括:将包含聚烯烃树脂(A)层和(根据JIS K7126在30℃下测定的)空气渗透系数为0.5×10-12cc·cm/cm2·sec·cmHg或更小且平均厚度(ε)满足0.05<ε<20μm的低渗透性树脂(B)薄膜层的层合膜(其中(A)层/(B)层处于假粘合态并且根据JIS K6256在30℃下测定的剥离强度小于0.05N/mm)与未硫化橡胶组合物(C)层以(A)层/(B)层/(C)层的顺序层合,以使(B)层牢固粘合于(C)层,并使(C)层和(B)层的(根据JIS K6256在30℃下测定的)剥离强度为0.05N/mm或更大,随后从所得层合物剥离(A)层,以形成包含(B)层和(C)层的低渗透性橡胶层合物。
Description
技术领域
本发明涉及一种使用低渗透性树脂多层膜制备低渗透性橡胶层合物的方法,更具体而言涉及一种制备低渗透性树脂的薄膜和可用于轮胎应用的基于二烯的橡胶组合物层的低渗透性橡胶层合物的方法。
背景技术
用于轮胎元件的橡胶组合物包含配混了炭黑和硫化剂并因此具有高粘度的橡胶。此外,在高温下橡胶交联,因此对成形温度存在限制。例如,难以共挤出高成形温度的乙烯/乙烯醇共聚物(EVOH)(成形温度:190-250℃)来制造EVOH薄膜/橡胶组合物的层合物,因此形成EVOH薄膜的单层,然后通过与橡胶组合物层合的方法是不可能的。工业上还没有建立制备EVOH薄膜/橡胶组合物层合物的方法。也没有这类技术的已知的现有技术文献。
发明内容
因此,本发明的目的是提供一种容易地制备低渗透性树脂薄膜和未硫化橡胶组合物的均匀的低渗透性橡胶层合物的方法。
根据本发明,提供了一种制备包含层合在橡胶组合物(C)层上的低渗透性树脂(B)薄膜层的低渗透性橡胶层合物的方法,其包括:
(i)制备聚烯烃类树脂(A)层和基于JIS K7126在30℃下测定的空气渗透系数为0.5×10-12cc·cm/cm2·sec·cmHg或更小且平均厚度ε为0.05<ε<20μm的低渗透性树脂(B)薄膜层的低渗透性多层膜,其中(A)层/(B)层处于假粘合态并且(A)层/(B)层根据JIS K6256在30℃下测定的剥离强度小于0.05N/mm,
(ii)以(A)层/(B)层/(C)层的顺序,在低渗透性多层膜上层合未硫化橡胶组合物(C)层,以粘结(B)层/(C)层,以使(C)层和(B)层的根据JIS K6256在30℃下测定的剥离强度为0.05N/mm或更大,和
(iii)从(B)层上剥离所得层合物的假粘合态的(A)层。
根据本发明,进一步提供了一种制备包含层合在橡胶组合物(C)层上的低渗透性树脂(B)薄膜层的低渗透性橡胶层合物的方法,其包括:
(i)制备聚烯烃类树脂(A)层和基于JIS K7126在30℃下测定的空气渗透系数为0.5×10-12cc·cm/cm2·sec·cmHg或更小且平均厚度ε为0.05<ε<20μm的低渗透性树脂(B)薄膜层以及增粘剂/粘合剂(D)层的低渗透性多层膜,以(A)层/(B)层/(D)层的顺序层合,其中(A)层/(B)层处于假粘合态并且(A)层/(B)层根据JIS K6256在30℃下测定的剥离强度小于0.05N/mm,
(ii)以(A)层/(B)层/(D)层/(C)层的顺序,在低渗透性多层膜上层合未硫化橡胶组合物(C)层,以粘结(D)层/(C)层,以使(C)层和(D)层的根据JISK6256在30℃下测定的剥离强度为0.05N/mm或更大,和
(iii)剥离所得层合物的假粘合态的(A)层。

附图简要说明

本发明的最佳实施方式
本发明发明人致力于解决上述问题,结果发现了通过使低渗透性树脂(B)薄膜层假粘合于聚烯烃树脂(A),以得到低渗透性多层膜(A)/(B),随后直接或通过增粘剂/粘合剂(D)层与橡胶组合物(C)层合,可以得到(A)层/(B)层/(C)层或(A)层/(B)层/(D)层/(C)层的层合物,并通过剥离(A)层,我们成功地均匀制备了所需低渗透性的(B)层/(C)层或(B)层/(D)层/(C)层的层合物。
在本发明的第一方面,通过如下方式可以制备包含层合在橡胶组合物(C)层上的低渗透性树脂(B)薄膜层的低渗透性橡胶层合物:
将由假粘合态层合的聚烯烃类树脂(A)层和低渗透性树脂薄膜层组成的(A)层/(B)层的层合膜,其中低渗透性树脂薄膜层基于JIS K7126在30℃下测定的空气渗透系数为0.5×10-12cc·cm/cm2·sec·cmHg或更小,优选0.1cc·cm/cm2·sec·cmHg或更小,且平均厚度ε为0.05<ε<20μm,优选1-10μm,低渗透性多层膜(A)/(B)基于JIS K6256在30℃下测定的(A)层/(B)层剥离强度为小于0.05N/mm,优选0.01N/mm或更小,以及未硫化橡胶组合物(C)层和所述(B)层的基于JIS K6256在30℃下测定的剥离强度为0.05N/mm或更大,优选0.05-5N/mm,与
橡胶组合物(C)层以(A)/(B)/(C)的顺序层合,粘结(B)/(C)层,
然后通过一般方法剥离假粘合态的(A)层(如使用与(A)层具有粘性的表面处理的缠绕辊,将(B)/(C)紧密地压在一起,然后仅缠上(A)层并将(A)层合在缠绕辊上)。
根据本发明的第二方面,通过如下方式可以制备包含经由增粘剂/粘合剂(D)层层合在橡胶组合物(C)层上的低渗透性树脂(B)薄膜层的低渗透性橡胶层合物:
以(A)层/(B)层/(D)层的顺序,在聚烯烃类树脂(A)层和低渗透性树脂(B)的薄膜层的(B)层侧上层合增粘剂/粘合剂(D)层,得到低渗透性多层膜,以(A)层/(B)层/(D)层/(C)层的顺序层合低渗透性多层膜(即(A)层/(B)层)和橡胶组合物(C),以使(A)层/(B)层处于如上所述的假粘合态,并且(A)/(B)的剥离强度(注释:测定方法如上所述)小于0.05N/mm,此外未硫化橡胶组合物(C)层和(D)层基于JIS K6256在30℃下测定的剥离强度为0.05N/mm或更大,优选0.05-5N/mm,将(D)层/(C)层合在一起,然后通过如上所述一般方法剥离假粘合态的(A)层。
这样,根据本发明,可以直接或经由增粘剂/粘合剂(D)层将低渗透性树脂(B)薄膜层在与聚烯烃树脂(A)层假粘合的状态下,与硫化前的橡胶组合物(C)粘结,因此可以在硫化前在橡胶组合物(C)层上,直接或经由增粘剂/粘合剂(D)层,均匀和简单地层合低渗透性树脂(B)薄膜,而无需将低渗透性树脂(B)薄膜共挤出或形成用于层合的单层。如此获得的低渗透性多层膜例如可将低渗透性树脂(B)薄膜层用作充气轮胎的内片(inner sheet)。橡胶组合物(C)层可充当低渗透性树脂(B)薄膜层的保护层,或充当防湿层用于抑制由于湿度引起的(B)层的气体阻隔性能的降低。
根据本发明,在第一和第二方面,通过在低渗透性多层膜的低渗透性树脂(B)层侧经由一般方法进一步层合与橡胶组合物(C)相同或不同的橡胶组合物(C’),可以得到其中低渗透性树脂(B)薄膜层被橡胶组合物(C)和(C′)(注释:橡胶组合物(C)和(C′)可相同或不同)夹在其中的结构的低渗透性橡胶层合物。
可用于本发明的聚烯烃类树脂(A)不受特别限制,只要其满足与(B)的剥离强度。特别地,例如,可提及但不局限于高密度聚乙烯(HDPE)、低密度聚乙烯(LDPE)、聚丙烯(PP)、聚(4-甲基-1-戊烯)等。
可用于本发明的低渗透性树脂(B)不受特别限制,只要其满足空气渗透系数(注释:该值越大,可获得的所需气体阻隔性能越小,因此越不优选)并满足(A)/(B)的剥离强度以及(B)/(C)的剥离强度,但具体而言优选使用主要包含乙烯-乙烯醇共聚物的组合物。也可使用气体阻隔性能树脂如聚乙烯醇(PVA)、聚偏二氯乙烯(PVDC)。
本发明的聚烯烃类树脂(A)和低渗透性树脂(B)的低渗透性多层膜可通过将树脂(A)和(B)经由常规方法多层挤出、吹胀成形等而制备。具体条件不受限制。可使用一般方法进行制备。
作为可用于本发明的橡胶组合物(C)和(C′),可以使用任何可用于充气轮胎的橡胶。可特别提及但不局限于:天然橡胶、聚丁二烯橡胶、苯乙烯-丁二烯共聚物橡胶、聚异戊二烯、丁基橡胶、卤化丁基橡胶、乙丙橡胶等。要注意的是橡胶组合物可含有炭黑、二氧化硅或其它增强剂(填料),硫化剂或交联剂,硫化促进剂或交联促进剂,各种类型的油,抗氧化剂,增塑剂,和通常包括在轮胎用途或其它橡胶组合物用途中的其它各种类型的添加剂。可通过一般方法混合这些添加剂以得到用于硫化或交联的组合物。这些添加剂的配混量可以是常规的一般配混量,只要本发明目标不受不利影响。
可用于本发明的增粘剂/粘合剂(D)不受特别限制,只要满足与橡胶组合物(C)的剥离强度。例如可提及,具有环氧基或含有无水马来酸基的苯乙烯-丁二烯-苯乙烯共聚物(SBS),其可以与萜烯树脂、萜烯苯酚树脂、芳族萜烯树脂、松香酯类树脂等混合。要注意的是这些增粘剂/粘合剂(D)层可包括一般硫化促进剂(如噻唑类硫化促进剂、秋兰姆类硫化促进剂或亚磺酰胺类硫化促进剂)或硫化促进助剂(如氧化锌、硬脂酸或硬脂酸锌)和其他常用添加剂。
可用于本发明的树脂中可以已经共混入任何常用于配混的添加剂,如抗氧化剂、防老剂、着色剂、增塑剂、填料、加工助剂等。
