Description

紫外线稳定的聚乙烯醇缩丁醛片材
                        本发明背景
本发明涉及在安全层压板中与玻璃一起使用的聚乙烯醇缩丁醛(PVB)片材。
PVB片材广泛用在用于建筑用窗、汽车挡风玻璃、天窗等的与一层或多层玻璃结合的层压板中。当玻璃层压板在暴露于来自日光的紫外(UV)射线下使用一定时间后，夹层片材将可能发生化学降解、脱色或褪色。因此在片材配方中通常使用紫外线吸收剂以防止这种现象的发生或使该现象的发生减少到最小。
在玻璃层压板制备的过程中或在以后的使用过程中沿暴露的片材边缘可从湿热的环境中吸收高达约为片材2％(重量)的水分。这是我们所不希望发生的，因它将导致沿层压板的边缘与玻璃脱层。
片材配方中粘合控制剂(ACA)控制着片材粘合到玻璃上的状况，以提供对玻璃层压板冲击的能量吸收。虽然适用于此目的，但一些ACA在高的夹层水分的水平下将得到零粘合。有机一元羧酸的多价金属盐能控制这种粘合，并且对于片材的水分吸收具有所需的相对不灵敏性。然而很遗憾的是，本发明人发现即使是在特定的紫外线吸收剂的存在下，PVB片材中的多价金属盐也将对其紫外线稳定性产生不利的影响。
               本发明概要
在PVB片材抵制暴露的紫外光的性能方面现已取得改进。
因此本发明的主要目的是在包含作为ACA的多价金属羧酸盐的PVB片材中提供紫外线稳定性。
其它目的部分是明显的，部分从下述说明书及权利要求书中是显而易见的。
通过提供包含多价金属盐和具有下式的使紫外线稳定量的苯并三唑基的化合物的聚乙烯醇缩丁醛片材来实现这些和其它目的：
Figure A9719473000041
式中，R1代表CH3、直链或支链的C5烷基或直链或支链的C12烷基，R2代表CH3或直链或支链的C5烷基。
                     附图的详述
在描述本发明的过程中将参照附图，其中图1和2是含有不同紫外线吸收剂的PVB片材的泛黄度对暴露紫外光的时间的曲线图。
                     本发明的详述
在本发明的紫外线稳定的片材中的ACA大都是C1-C8有机、优选脂族一元羧酸的多价、优选二价金属盐，其中所述金属阳离子通常是镁、钙或锌。可用这些盐的混合物。具代表性的阴离子是乙酸根、丁酸根、取代的丁酸根如2-乙基丁酸根、辛酸根等。优选2-乙基丁酸镁。在片材配方中的这些多价金属盐控制着其粘合到玻璃上的状况并且更重要的是将片材中水分含量维持在所需的广域范围内，可高至约2％(重量)。一价金属盐通常作为来自将用于缩醛化聚乙烯醇(PVOH)以生成PVB树脂的酸性催化剂中和的过程所引出的结果，存在于片材中。通常将乙酸钾用于这种中和过程，并且在干燥后仍被截留在树脂中。片材中的这种一价盐与多价盐一样影响着粘合状况，但比起后者来前者对水分更为敏感。对于所需的水分低灵敏度而言，片材配方中多价金属盐的量应使得可提供至少3个EDTA滴定单位(在下文定义)。基于PVB树脂计，片材中ACA的总的浓度一般约为0.01-0.1％(重量)，优选0.01-0.05％(重量)。
PVB树脂的重均分子量大于70,000，优选约为100,000-250,000(通过大小排阻色谱法用小角度激光散射测得)。基于重量计，PVB通常包含少于19.5％，优选约为17-19％的按聚乙烯醇(PVOH)计算的羟基；0-10％，优选0-3％的按聚乙烯酯如乙酸酯计算的残余酯基，其余为缩醛，优选为丁醛缩醛，但除缩丁醛外可任选地包括少量的缩醛基，例如见述于U.S.5,137,954(1992年8月授权)中的2-乙基己醛。
通过已知的水溶液或溶剂缩醛化方法，在酸性催化剂的存在下使PVOH与丁醛反应，然后中和催化剂、分离、稳定化和树脂的干燥来生产PVB树脂。它可从Monsanto Company以Butvar树脂购买到。
片材的PVB树脂通常每100份树脂用约20-80份，更常用25-45份增塑剂来增塑。常用的增塑剂是多元酸或多元醇的酯。适宜的增塑剂是三甘醇二(2-乙基丁酸酯)、三甘醇二(2-乙基己酸酯)、四甘醇二庚酸酯、己二酸二己酯、己二酸二辛酯、己二酸庚酯和己二酸壬酯的混合物、癸二酸二丁酯、聚合增塑剂如石油改性的脂肪醇酸和例如见述于U.S.第3,841,890号中的磷酸酯与己二酸酯的混合物以及例如见述于U.S.第4,144,217号中的己二酸酯和邻苯二甲酸烷基苄基酯。以及如见述于US.5,013,779中的从C4-C9烷基醇和环状C4-C10醇中制得的混合己二酸酯。C6-C8己二酸酯如己二酸己酯为优选的增塑剂。
相应于式(1)的紫外线吸收剂的量可以变化，通常每100份PVB为0.1-1份。
除了增塑剂、根据上述式(1)的紫外线吸收剂以及ACA外，PVB片材还可含有其它增强性能的添加剂如用来使片材全部或部分着色的颜料或染料、抗氧化剂等。
通过将紫外线吸收剂、ACA和增塑剂混合，然后与PVB树脂混合，再使混合物在压力下通过口模以形成片材来制备片材。其厚度通常约为0.13-1.3毫米以在玻璃层压板中提供一适宜的冲击力吸收。
通过各种已知的方法，使用本发明的片材来制备玻璃层压板。将PVB片材插入玻璃层之间(或与玻璃单层组合)，然后将组合件置于压力约为1034-2067kPa、约90-165℃的高压釜中至少10分钟，以使各层紧密粘合并形成安全玻璃层压板。
下述实施例用来说明本发明，但并非限制本发明。用量及百分数都是以重量计。
在实施例中所述的各种性能基本上都是根据以下方法测定的。
泛黄度指数(YI)ASTM D1925。该数值越高，则泛黄度越大。
EDTA(乙二胺四乙酸)滴定度-测定片材中多价(非一价)羧酸金属盐浓度。1个EDTA滴定度单位等于每百万份PVB树脂25.4份2-乙基丁酸镁(Mg2EB)。将7克增塑的PVB片材溶解于甲醇中。加入12-15毫升缓冲液10溶液(氯化铵/氢氧化胺)和12-15滴甲醇中的羊毛铬黑T指示剂。滴定前，将光度计上的百分比透射率调节至约80％。加入羊毛铬黑T后，试样变成鲜品红粉红色。滴定结束后溶液为深靛蓝色。一个EDTA滴定度单位等于1×10-7摩尔多价金属盐/克PVB。
EMMA照射量-ASTM D4364。EMMA是DSET Laboratories的注册商标。该方法描述了利用Fresnel-反射聚焦器(concentrator)来测定在Arizona中的加速室外风化情况(使用聚焦的自然阳光)。照射量以兰勒计量，其中1兰勒=0.04184MJ/米2。
                  实施例1、2和C1-C4
A)该实施例显示多价(二价)羧酸金属盐粘合控制剂的水分容限。
将水分含量为0.2％-2％、用己二酸二己酯增塑并含有每百万份PVB树脂380份2-乙基丁酸镁(多价盐)的PVB片材按常规层压到两个玻璃层之间，并在-18℃用击打粘合(pummel adhesion)(PA)试验来测定片材粘合到玻璃上的状况。在该试验中，用1磅(454g)的圆头锤击打玻璃层压板以打碎玻璃并将未粘合到PVB层的碎玻璃移走。将剩下的粘合的玻璃与一组已知击打等级的标准目测比较，标准值越高，则仍粘合到片材上的玻璃就越多，即当击打为0时，没有玻璃剩下，而当击打为10时，则100％的夹层表面粘合到玻璃上。良好的冲击分散作用对应于约为2-7的击打粘合值。小于2时，将丧失太多的玻璃，而大于7时，粘合力又太高。在0.2％水时，PA为7,2％水时，PA为6。为了比较，在相同的PA下(0.2％和2％)仅使用一价金属盐即乙酸钾(KOAc)的片材水分分别为7和0。这就证实了多价金属羧酸盐ACA对于水分的相对不灵敏性。
B)片材紫外光容限。将含有32phr己二酸二己酯增塑剂、有效粘合控制量的2-乙基丁酸镁和各种苯并三唑紫外线稳定剂/吸收剂的PVB片材层压到两层浮法玻璃之间并根据ASTM D 4364曝光不同的时间段。每个配方中紫外线稳定剂的摩尔量相同。曝光结果绘于图1和图2中。配方的细节示于表1中。实施例C1-C4并非根据本发明，虽然为了方便分析起见，这些对比实施例用于苯并三唑的结构基团被定义为与用于本发明实施例1和2中的R1和R2名称相同，并示于上式(1)中。具有负的YI的试样在颜色上看起来带兰色，它来自与明净玻璃相关的兰色。

从以上的曝光数据可看出，与实施例1和2相比，对比例C1、C2和C3的YI迅速增加(C2为1M兰勒及C1和C3超过0.5M兰勒)。曝光水平为1ML的YI被认为是代表含有一特定的紫外线稳定剂的层压板的长期性能。虽然其苯并三唑化合物的结构与实施例1和2的结构相对类似，但在紫外线稳定性能上对比实施例C1-C3是不能接受的。在对比例中泛黄度的增加相信是由于多价ACA盐与紫外线吸收剂之间发生结合作用所致。这就导致在C4中仅使用一价乙酸钾作为ACA表示出＜0.5YI(1M兰勒后)的结果。虽然实施例2仅曝光至0.5L，但在1M兰勒处可预计得到可接受的性能(＜0.5YI)。
当R1为CH3时，可预计得到与实施例1和2相类似的性能。虽然在上述实施例中金属阳离子是镁，但使用其它二价金属阳离子也预计可获得类似的结果。泛黄度通过本发明得以降低或避免与PVB增塑剂的类型无关。使用其它的增塑剂即四甘醇二庚酸酯、三甘醇二庚酸酯和三甘醇二-2-乙基己酸酯可获得与实施例1和2类似可接受的YI。
