  • the present invention relates to an additive, and more particularly to an additive for a thermoplastic polymer, a process for the preparation thereof, and a polymer composition composed of the same.
  • Thermoplastic polymers are widely used in the fields of home appliances, packaging, automobiles, transportation and decoration, and require good surface sliding properties under certain conditions of use.
  • the standard requirements for the surface sliding property cannot be met, and thus many prior art techniques improve the surface of the plastic by various means.

Description

一种用于聚合物的添加剂 技术领域
本发明涉及一种添加剂，具体涉及一种用于热塑性聚合物的添加剂及其制备方法以及由其组成的聚合物组合物。
背景技术
热塑性聚合物广泛用于家电、包装、汽车、交通与装修等领域，在某些使用条件下需要良好的表面滑动性能。但是塑料由于表面硬度低，或者由于助剂迁移等原因造成表面摩擦系数增大，如果不加以改性，不能满足表面滑动性能的使用标准要求，于是许多在先技术通过多种途径改善塑料的表面滑动性能，公开号CN1236375A的专利通过提高聚丙烯材料的结晶度来提高表面滑动性能；公开号为CN1294614A的专利通过添加接枝共聚物提高树脂的表面滑动性能。这些技术在一定程度上解决了聚合物表面滑动性能差的缺陷，但是均需要添加新的助剂，会造成其它性能的下降。
Figure PCTCN2016111243-appb-000001
如上式所述的四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷是一种重要的用于热塑性聚合物的商业添加剂。例如，它保护有机材料，尤其是热塑性聚合物以抵制热、氧化和/或光化的降解。一般来说，由2，6-二叔丁基苯酚和丙烯酸甲酯先进行加成反应，生成β-(3，5-二叔丁基-4-羟基苯基)丙酸甲酯，然后再与季戊四醇进行酯交换反应制得。常规工艺制得的四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷对热塑性聚合物的表面滑动性能并没有改进，甚至会造成某种程度的降低。鉴于此种矛盾，业内技术人员对于改进表面滑动性能的努力一直在持续。
发明内容
本发明人通过多次实验惊奇的发现，当四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷作为添加剂用于聚合物中时，通过调整四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷的合成工艺从而得到一种特定范围静止角(也称为休止角)的四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷化合物，将其加入到聚合物中，对聚合物滑动性能的提高具有明显的作用。究其原理，可能是因为特定范围静止角的四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷化合物加入到热塑性聚合物中，改变了某些热塑性聚合物的结晶度，从而 提高了聚合物的内聚力，使得聚合物表现出良好的滑动性能。
本发明是通过以下技术方案实现的：
一种用于聚合物的添加剂A，由如式I所示结构式的化合物组成：
Figure PCTCN2016111243-appb-000002
其化学名称可以为：四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷，所述添加剂A的静止角是38°-48°，优选40°-45°。所述静止角，是指颗粒在不受任何限制和帮助下，由高点自然落到水平面上所形成的圆锥体的斜面与锥底平面构成的夹角，也称为休止角，按照GB 11986-89进行测试。
所述添加剂A具有至少55J/g的熔化焓，优选具有60-80J/g的熔化焓，更优选具有70-75J/g的熔化焓，其中所述熔化焓根据ISO11357-1/2测定，并且其中差示扫描量热法(DSC)以20K/分钟的加热速率进行。
所述添加剂A的堆密度为0.30g/cm3～0.60g/cm3，优选0.40g/cm3～0.50g/cm3。
为得到本发明特定范围静止角的添加剂A，本发明的制备工艺与常规工艺不同。
常规的以2，6-二叔丁基苯酚为起始原料制取四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷的工艺路线有一步法、二步法，国内企业主要以二步法为主。
所谓二步法就是：将2，6-二叔丁基苯酚与丙烯酸甲酯在碱性条件下进行对位加成反应，生成中间产物3，5-二叔丁基-4-羟基苯丙酸甲酯，3，5-二叔丁基-4-羟基苯丙酸甲酯经过结晶提纯后再与季戊四醇在含锡催化剂的条件下进行酯交换反应，生成四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷粗产品，粗产品精制后得到最终产品。这种经过3，5-二叔丁基-4-羟基苯丙酸甲酯提纯后再与季戊四醇进行酯交换反应的工艺，称为二步法工艺。
本发明采用的制备工艺是通过改进3，5-二叔丁基-4-羟基苯丙酸甲酯与季戊四醇的反应而制备四(β-(3，5-二叔丁基-4-羟基苯基)丙酰氧基甲基)甲烷的酯交换方法，即改进了二步法的第二步工艺，而第一步工艺可以采用常规工艺进行反应。其中本专利改进的制备工艺是在由氢氧化铝和异辛酸钠组成的酯交换催化剂结合物的存在下进行，其中该反应通过以下阶段进行：其中仅有氢氧化铝催化剂存在于反应混合物中的第一阶段，随后当反应5-12小时后，将异辛酸钠催化剂加入到反应混合物中而开始第二阶段。
本发明还提供一种添加剂组合物，包含所述的添加剂A和至少一种不同于添加剂A的其 它添加剂B；所述添加剂组合物优选包含50至99.9％重量的添加剂A、和0.1至50％重量的至少一种不同于添加剂A的其它添加剂B。
