Description

一种可透射激光的无卤阻燃增强PBT组合物及其制备和应用 技术领域
本发明属于加工塑料领域，特别涉及一种可透射激光的无卤阻燃增强PBT组合物及其制备和应用。
背景技术
激光焊接技术是借助激光束产生的热量使塑料接触面熔化，将模塑零部件粘结在一起的技术。与传统的热板焊接、振动摩擦焊接、超声波焊接相比，激光焊接效率高、环境污染小、特别适用于汽车塑料零部件的流水线加工，尤其是塑料零部件是非常精密的电子元件或要求无菌环境时，激光焊接技术具备明显的优势。近年来，随着新能源汽车的发展，越来越多的电子元件，如电子执行器、管路接头采用激光焊接的工艺，在该领域内，阻燃PBT材料应用广泛，因此对无卤阻燃增强PBT材料的透光率提出了更高的要求。
聚对苯二甲酸丁二醇酯(英文名polybutylene terephthalate，简称PBT)，是由对苯二甲酸和1,4-丁二醇缩聚制成的聚酯，为结晶性工程材料，树脂呈半透明状态，玻璃纤维和阻燃剂加入到PBT树脂后，复合材料的透光度极大的降低，无卤阻燃增强PBT材料作为激光焊接的透光层材料面临透光度不足的问题。
发明内容
针对现有技术的缺陷，本发明所要解决的技术问题是提供一种可透射激光的无卤阻燃增强PBT组合物及其制备和应用。
本发明的一种PBT组合物，按重量份数，组分包括：
其中PBT树脂为特性粘度0.8-1dL/g；特性粘度测试标准GB/T 14190-2008。
所述PA6T/6I中PA6T重量含量不高于41％。
PBT树脂：聚对苯二甲酸丁二醇酯。
PA6T/6I：聚对苯二甲酰己二胺/聚间苯二甲酰己二胺共聚物。
优选地，所述无卤阻燃剂为有机次磷酸锌、有机次磷酸铝中的至少一种。
优选地，所述氨基类硅烷偶联剂为γ-氨丙基三甲氧基硅烷、γ-氨丙基三乙氧基硅烷、N-(2-氨乙基)-3-氨丙基三乙氧基硅烷中的一种或几种。
优选地，所述抗氧剂为受阻酚类抗氧剂(如抗氧剂1010、1076、1098)、亚磷酸酯类抗氧剂(抗氧剂168)中的一种或几种；所述润滑剂为酯类(如聚乙二醇酯、多元醇酯)、褐煤酸盐、乙撑双硬脂酸酰胺、聚乙烯蜡中的一种或几种。
优选地，所述成核剂为Na2CO3、NaHCO3中的至少一种。
优选地，所述PA6T/6I中PA6T的重量含量为30-40％。
优选地，按重量份数，组分包括：
本发明的一种所述PBT组合物的制备方法，包括：
氨基类硅烷偶联剂的溶液和扁平玻纤搅拌混匀，烘干，得到氨基类硅烷偶联剂处理后的扁平玻纤；
将PBT树脂、PA6T/6I、抗氧剂、润滑剂和成核剂按配比预混后，由双螺杆塑化，将氨基类硅烷偶联剂处理后的扁平玻纤、无卤阻燃剂分别按比例由不同的侧喂口加入，经过牵引、冷却、切粒、干燥后，得到PBT组合物；双螺杆挤出机设置温度为220～250℃，螺杆转速为300～400转/分。
所述烘干温度为80-100℃，时间为10-12h。
本发明的一种所述PBT组合物在塑料电子元件或能源汽车中的应用，如电子阀体、控制器、高压连接器、电控盒等。
原理：PBT是一种具备聚酯结构的高分子材料，PA材料是一种具有酰胺键结构的高分子材料，含有PA6T结构的聚酰胺材料与PBT有一定的相容性，能提高PBT的透光性， 当PA6T的含量较高时，理论上与PBT的相容性提高，但此时PA6T/6I材料的刚性较大，分子链运动能力较弱，与PBT材料加工时的混合效果很差，不利于材料透光性的提高；当PA6T的比例降低时，材料的分子链运动能力增强，能够与PBT材料在分子层面有很好的混合效果，兼顾材料的力学性能和透光性。
PBT的特性粘度低于0.8dL/g时，PBT的分子量较小，分子量分布较宽，制备的复合材料力学性能偏低；当PBT的特性粘度高于1.0时，PBT的分子量太高，粘度大，结晶度高，不利于材料的分散和相容，影响材料的力学和透光性能。
有益效果
本发明的阻燃增强PBT材料可同时满足可激光焊接性、高强度、无卤化的要求；缺口冲击强度≥9.8KJ/m2以上，透光率≥27％，阻燃达到V-0～V-1等级。

实施例1和对比例1-2可知，PBT粘度过大或过小，透光性能差、冲击也差。
本发明中无卤阻燃增强PBT组合物具有阻燃性、较好的缺口冲击强度的同时，透光率为27％以上能够满足可激光焊接性。
