Heat-conducting high-temperature-resistant balancing daub and preparation method thereof
The invention relates to a heat-conducting high-temperature-resistant balancing daub and a preparation method thereof, and belongs to the technical field of balancing daub. The resin mud is formed by kneading 10-20 parts of organosilicon epoxy resin, 35-45 parts of a composite filler and 8-12 parts of a diluent, the cured mud is formed by kneading 9-15 parts of a curing agent, 1-3 parts of an accelerant, 20-30 parts of the composite filler and 10-15 parts of a solvent, the composite filler is formed by mixing branched boron nitride, mica powder, silica fume and tungsten carbide powder, and the diluent and the curing agent are mixed. Branched boron nitride is of a strut-shaped boron nitride structure and has good heat conductivity, and compared with existing spherical or porous structure heat conduction filler, the branched structure can be embedded with a resin matrix, increase the heat transfer area and improve the heat conduction efficiency, and meanwhile, the branched structure and the resin matrix form nail rolling strengthening, so that daub is not prone to deformation, and the balance weight stability is kept.
本发明涉及一种导热型耐高温平衡胶泥及其制备方法，属于平衡胶泥技术领域。该平衡胶泥包括由有机硅环氧树脂10‑20份、复合填料35‑45份和稀释剂8‑12份捏合而成的树脂泥，由固化剂9‑15份、促进剂1‑3份、复合填料20‑30份和溶剂10‑15份捏合而成的固化泥，其中，复合填料由支状氮化硼、云母粉、硅灰和碳化钨粉混合而成，支状氮化硼呈现支柱状氮化硼结构，本身具有良好的导热性，其与现有的球粒型或者多孔结构导热填料相比，支状结构可与树脂基体嵌合，增大传热面积，提高导热效率，同时与树脂基体形成钉轧强化，使得胶泥不易发生形变，保持配重稳定性。
