Abstract

在聚氯乙烯复合材料的配方中，用（ＲＣＯＯ）ａＭ（ＯＸ）ｂ其中Ｒ为烃基；Ｍ为金属元素；Ｘ为磷酰基或磺酰基］代替常用的单烷氧型钛酸酯偶联剂，有良好的物料间的相容性和流变性。此种偶联剂对无机填料的种类和含水量无特殊要求，且成本低。复合材料成型后其拉伸强度与伸长率都不低于用ＮＤＺ－１０２偶联剂（南京曙光化工厂生产）的复合材料。叙述了此种偶联剂的合成方法。

Description

一类聚氯乙烯复合材料的配方
本发明属于一类聚氯乙烯复合材料的配方。
聚氯乙烯树脂中常加入无机填料以改善其力学性能和减少制品的树脂用量，但无机填料和树脂间的相容性差，树脂加入无机填料后，加工时的流变性小，给加工带来困难。目前的配方是加入单烷氧型钛酸酯偶联剂以改善物料间的相容性和加工时的流变性。此类钛酸酯含有一个水解基团〔如异丙氧基〕，因此对无机填料的含水量有较严格的要求，并且单烷氧型钛酸酯的成本较高。
本发明的目的在于提供一类对无机填料含水量的要求不严格的，成本较低的聚氯乙烯复合材料的配方。
本发明提供了一类聚氯乙烯复合材料的配方，其特征是将以化学式（RCOO）aM（OX）b为代表的物质代替钛酸酯加入到树酯，无机填料或其它助剂的配料中，以改善物料之间的相容性和加工时的流变性。在式（RCOO）aM（OX）b中，M中心原子可以为Ca、Sr、Ba、Al、Sn、Pb、Mn、Fe、Ti、Zr、Sb、Bi、V、Cu、Cr、Co、Ni、Zn、Cd等金属元素，R可以为C7-C21饱和或不饱和的烃基或者芳香族烃基，X可以为二异辛氧基磷酰基

、十二烷基苯磺酰基、十二烷基磺酰基
Figure 85102666_IMG2
基团，b≥a，a≥0，且a+b＝n，n为金属原子M的氧化数。此类物质〈＆＆〉PH＝6-11的水溶液中，于室温至100℃之间，将相当于M（OH）n的化合物与RCOOH和磷酸二异辛酯作用制得：
M（OH）n+aRCOOH+bHOX（RCOO）aM（OX）b
由于（RCOO）aM（OX）b中不含有水解基团，因此对无机填料的种类和其含水量均无特殊要求，且成本比钛酸酯低得多。它使无机填料与树脂间的相容性改善，流变性增加，在1000份CaCO3和1500份矿物油中含有5份（RCOO）aM（OX）b时，体系的粘度如下：

在本配方中若加入环氧大豆油，可以减少或代替热稳定剂铅盐的用量。
以下通过具体实施例进一步说明本发明内容。

例2.在500ml水中加入Al2（SO4）3·18H2O333克，搅拌，然后加入NaHCO3调节PH＝6～8，加入油酸282克，磷酸二异辛酯644克，搅拌均匀，在50～80℃下反应二小时后，除去水层，用去离子水洗至无 <math><msup><mi>SO</mi><msub><mi>2-</mi></msup><mi>4</mi></msub></math> 存在，干燥后得，它为白色固体，熔点为141.8～148℃。
例3.聚氯乙烯复合材料配方：PVC（三型）〔镇江树脂厂生产〕：100份;轻质CaCO3（320目全通过）〔南京跃进炼灰厂生产〕：100份;三盐：5份;硬脂酸铅;1份;硬脂酸钡：1.5份;DOP：20份;：1份，配料后，在198℃加工成型，其拉伸强度横向为204.9kg/cm2;纵向为226.2kg/cm2（用ND-102偶联剂分别为202.1kg/cm2和238.9kg/cm2），其伸长率横向为10.0%;纵向为15.2%（用ND-102偶联剂分别为8.8%和11.2%）。
