本发明涉及绝缘导热材料技术领域，特别涉及一种高机械强度的绝缘导热塑料。The invention relates to the technical field of insulating and heat-conducting materials, in particular to an insulating and heat-conducting plastic with high mechanical strength.
背景技术：Background technique:
在电子技术领域，由于电子线路的集成度越来越高，热量的聚积越来越多。热量的集聚导致器件温度升高，工作稳定性降低。根据Arhennius公式，温度每升高10℃，处理器寿命降低一半。因此，用于处理器的材料要求具有高导热性能，以便热量迅速传导出，达到降温目的。对于高集成度芯片，其设计热能是如此之高以致于普通散热装置难以保证有效散热，对于需要绝缘散热的器件多是通过高导热陶瓷，如氮化铝、氮化硼等承担。由于陶瓷产品的加工难度高，易破裂，人们开始寻求由容易加工、耐冲击的塑料来制备导热材料。In the field of electronic technology, due to the increasing integration of electronic circuits, the accumulation of heat is increasing. The accumulation of heat causes the temperature of the device to rise and the working stability to decrease. According to the Arhennius formula, for every 10°C increase in temperature, the life of the processor is reduced by half. Therefore, the material used for the processor is required to have high thermal conductivity, so that the heat can be conducted out quickly to achieve the purpose of cooling. For highly integrated chips, the design heat energy is so high that it is difficult for ordinary heat sinks to ensure effective heat dissipation. For devices that require insulation and heat dissipation, high thermal conductivity ceramics, such as aluminum nitride and boron nitride, are mostly used. Because ceramic products are difficult to process and easy to break, people began to seek heat-conducting materials made of easy-to-process and impact-resistant plastics.
目前采用基体塑料为聚丙烯、聚氯乙烯等通用塑料，导热填料主要有石墨、铝和铜粉及其纤维。因此绝缘性差，工作温度低。随着电子电器产业的迅猛发展，对绝缘导热塑料的需求越来越高，比如电路板绝缘材料、散热器件(如CPU散热器)、CPU风扇、电子隔离板、移动通信设备的外壳。要求既绝缘又导热，加工容易，成本低。中国专利CN200510101700.0公开了一种以大颗粒导热填料为主要填料的注射成型的导热绝缘塑料。其采用大颗粒的导热粉体增大填充量，复配细颖粒导热粉体增加导热网络的联通以及添加润滑剂保证一定的可注射流动性，具有较高的导热性能和良好的加工性能。但是其机械强度低，抗弯曲抗折扭的性能差，防压抗震能力差。At present, the base plastics are general-purpose plastics such as polypropylene and polyvinyl chloride, and the heat-conducting fillers mainly include graphite, aluminum, copper powder and their fibers. Therefore, the insulation is poor and the working temperature is low. With the rapid development of the electronic and electrical industry, the demand for insulating and heat-conducting plastics is getting higher and higher, such as circuit board insulation materials, heat dissipation devices (such as CPU heat sinks), CPU fans, electronic isolation boards, and casings for mobile communication equipment. It requires both insulation and heat conduction, easy processing and low cost. Chinese patent CN200510101700.0 discloses an injection-molded thermally conductive insulating plastic with large particle thermally conductive fillers as the main filler. It uses large-grained heat-conducting powder to increase the filling amount, compound fine-grained heat-conducting powder to increase the connection of the heat-conducting network, and add lubricant to ensure certain injectable fluidity. It has high thermal conductivity and good processing performance. However, its mechanical strength is low, its resistance to bending and bending is poor, and its ability to resist compression and shock is poor.
