Inorganic heat-conducting packaging material as well as preparation method and application thereof
The invention belongs to the technical field of inorganic functional materials. The invention provides an inorganic heat-conducting packaging material. The inorganic heat-conducting packaging material comprises 630-670 parts of magnesium oxide, 120-180 parts of magnesium sulfate, 60-95 parts of a network forming agent, 5-25 parts of a crystallization auxiliary agent, 3-20 parts of a beta-sodium naphthalene sulfonate formaldehyde condensate, 0-15 parts of latex powder and 300-350 parts of water. Through cooperation of all the components, the heat conductivity coefficient of the packaging material is obviously improved, and the packaging material is excellent in fluidity, good in adaptability to a system, easy to fill and seal an electric heating system and not prone to deformation after solidification. The invention also provides a preparation method of the inorganic heat-conducting packaging material, various components are uniformly dispersed by adopting a step-by-step mixing process, the process requirement is low, the caking and layering phenomena are avoided, and the preparation method is simple, rapid, convenient and good in economical efficiency.
本发明属于无机功能材料技术领域。本发明提供了一种无机导热封装材料，包含氧化镁630～670份、硫酸镁120～180份、网络形成剂60～95份、结晶助剂5～25份、β‑萘磺酸钠甲醛缩合物3～20份、乳胶粉0～15份、水300～350份。本发明通过各组分之间的配合，封装材料的导热系数得到了明显的提高，而封装材料的流动度优异，对系统的适应性好，易于充满和密封电热系统，凝固后不易变形。本发明还提供了无机导热封装材料的制备方法，采用分步混合的工艺将各种组分均匀分散，工艺要求低，不出现结块分层现象，制备方法简捷，快速方便，经济性好。
