Beschreibung
Zusammenfassung:	The invention relates to the field of nano calcium carbonate, in particular to a modification method of nano calcium carbonate for a silicone sealant. Nano calcium carbonate in different forms is selected and modified respectively to obtain nitrogen-containing nano calcium carbonate and phosphorus-containing nano calcium carbonate, then different modified nano calcium carbonate is compounded to obtain nano calcium carbonate for the silicone sealant, and the prepared silicone sealant has high hardness and high tensile strength, and can be used for preparing the silicone sealant. Meanwhile, the flame retardant grade is improved. 本发明涉及纳米碳酸钙领域，特别涉及一种硅酮密封胶用纳米碳酸钙的改性方法。本发明通过选用不同形态的纳米碳酸钙，并分别进行改性获得含氮纳米碳酸钙和含磷纳米碳酸钙，然后将不同改性纳米碳酸钙进行复配，获得硅酮密封胶用纳米碳酸钙，并使其制备得到的硅酮密封胶具有高硬度和高拉伸强度，同时提升阻燃等级。
