Summary:The invention discloses a quaternary mixed molten salt heat storage material and a preparation process thereof. The quaternary mixed molten salt heat storage material is prepared by mixing the following four types of materials according to different proportions: 30 to 40 percent by weight of LiNO3, 50 to 55 percent by weight of KNO3, 5 to 10 percent by weight of NaNO2 and 5 to 10 percent by weight of NaNO3; and the preparation of the quaternary mixed molten salt heat storage material is implemented by the step of preparation of single-component salt and the step of preparation of a mixed molten salt heat storage material. Because Ca(NO3)2 is added in mixed molten salt in the prior art, although the upper service temperature limit of the molten salt is increased, the fluidity of the molten salt becomes poor, easily causing local high-temperature deterioration. On the basis of the LiNO3 and the KNO3, the NaNO2 and the NaNO3 are added to form the four-component mixed molten salt heat storage material; proved by
