Preparation method of novel phase-change silicon dioxide aerogel heat insulation pad
The invention discloses a preparation method of a novel phase-change silicon dioxide aerogel heat insulation pad. The preparation method comprises the following steps: A, adding a phase-change material, a catalyst, organic silicon, ethanol and deionized water into a beaker according to a certain proportion, and uniformly stirring; b, putting a base material into the solution; c, putting the mixed solution into an aging device for aging treatment; d, putting the aged mixed solution into a drying box for drying treatment; and E, the dried material is modified to obtain the phase change aerogel heat insulation pad, the content of the phase change material is 15-20 parts, and the phase change material is composed of octadecanol, polyethylene glycol, silica sol, calcium chloride hexahydrate, sodium sulfate decahydrate, sodium hydrogen phosphate decahydrate, barium hydroxide octahydrate and magnesium chloride hexahydrate. According to the invention, the phase-change material, the catalyst, the organic silicon, the ethanol, the deionized water and the base material are used as raw materials, and the prepared heat insulation pad has very good inhibition and delay effects on heat spread generated by a thermal runaway battery cell in a battery module.
本发明公开了一种新型的相变二氧化硅气凝胶隔热垫的制备方法，包括以下步骤：A、将相变材料、催化剂、有机硅、乙醇、去离子水按一定比例加入烧杯后搅拌均匀；B、将基材放入溶液中；C、并将混合液放入老化器内进行老化处理；D、将老化后的混合液放入干燥箱内进行干燥处理；E、对干燥后的物料进行改性后得到相变气凝胶隔热垫，所述相变材料的含量为15‑20份，相变材料由十八醇、聚乙二醇、硅溶胶、六水氯化钙、十水硫酸钠、十水磷酸氢钠、八水氢氧化钡和六水氯化镁组成。本发明采用相变材料、催化剂、有机硅、乙醇、去离子水和基材为原料，所制得的隔热垫在电池模组内对热失控电芯产生的热蔓延具有很好的抑制和延缓作用。
