Description
技术领域
本发明属于SMC模塑料领域，具体涉及一种高导热SMC及其制备方法。
背景技术
片状模塑料，即SMC(Sheet Molding Compounds)，常称作不饱和聚酯树脂片状模塑料，是以不饱和聚酯树脂、引发剂、脱模剂、填料、色浆等先混合，然后浸渍短切玻璃纤维纱或者玻璃短切毡，并在两面用聚乙烯或者聚丙烯薄膜包覆起来形成的“三明治”型模塑料，然后通过熟化一定时间后得到的产品。SMC成型工艺是在高温高压条件下在闭合的模具内成型。与其他材料及成型工艺相比，SMC制品具有优良的力学性能、电气性能、耐热性能及耐化学腐蚀性，且产品尺寸稳定，成型周期短，轻量化，可实现阻燃要求，因此，该工艺适合应用在5G通讯产品上。
现有4G和5G通讯设备多采用塑料制品，而塑料制品的导热系数一般在0.2以下；一般SMC产品主要以碳酸钙和氢氧化铝做填料，产品的导热系数一般在0.5w/mk以下，由于5G通讯设备需要高的导热系数，只能采用高导热系数的材料。
发明内容
本发明的一个目的是针对以上要解决的技术问题，提供一种具有较高导热系数的适用于5G通讯设备的高导热片状模塑料。
本发明的另一个目的是提供上述高导热片状模塑料的制备方法。
为了实现以上发明目的，本发明提供了一种高导热SMC，其特征在于按重量计包括以下组分：55-65份不饱和聚酯树脂、35-45份低收缩添加剂、1.2份引发剂、0.8份阻聚剂、1.2份PE粉、4份脱模剂、1份BYK助剂、80份氢氧化铝、80份氮化铝或氮化硼、5份色浆、6份增稠剂、以及占前述全部组分重量之和20％-24％的无碱玻璃纤维。
优选地，所述高导热SMC按重量计包括以下组分：65份不饱和聚酯树脂，35份低收缩添加剂、1.2份引发剂、0.8份阻聚剂、1.2份PE粉、4份脱模剂、1份BYK助剂、80份氢氧化铝、80份氮化铝或氮化硼、5份色浆、6份增稠剂、以及占前述全部组分重量之和22％的无碱玻璃纤维。
优选地，所述低收缩添加剂为聚苯乙烯、聚醋酸乙烯酯、聚甲基丙烯酸甲酯或其混合物。
优选地，所述引发剂为过氧化苯甲酸叔丁酯。
优选地，所述阻聚剂为BHT、二叔丁基对甲酚、苯醌的一种或多种。
优选地，所述氢氧化铝的平均粒径为5-10微米。
优选地，所述氮化铝或氮化硼的规格为100目、400目和800目。更优选地，所述氮化铝或氮化硼为20-30重量份的100目氮化铝或氮化硼、20-30重量份的400目氮化铝或氮化硼和20-30重量份的800目氮化铝或氮化硼复配而成的混合物。
优选地，所述色浆为18重量％的炭黑溶于载体树脂中。
优选地，所述增稠剂为SMC模压通用增稠剂，优选35重量％的活性氧化镁(RA-150)分散于载体树脂中。
另一方面，本发明还提供了所述高导热SMC的制备方法，其包括以下步骤：
1)将不饱和聚酯树脂、低收缩添加剂、引发剂、阻聚剂、PE粉、脱模剂、BYK助剂、氢氧化铝、氮化铝或者氮化硼分散成均匀的树脂糊；
2)分别测定步骤1)中分散好的树脂糊、色浆、增稠剂这三个组分的流量，按比例输入SMC机组；
3)将步骤2)的三个组分导入SMC设备，同时加玻璃纤维，保证玻璃纤维浸渍良好；
4)熟化，达到设定粘度后得到所述高导热SMC。
本发明的高导热SMC引入了氮化铝和氮化硼，氮化铝和氮化硼具有高导热系数，通过合理的组分配比，将不同粒径的氮化铝、氮化硼与氢氧化铝及树脂形成致密的产品，在不改变SMC机械性能的基础上，产品具有较高的导热系数，此外，本发明采用基本方法生产SMC，可以使SMC大批量生产。
