Embodiment 1
[0014] Embodiment 1 (comparison table 1, 2 in embodiment row sequence, component, proportioning number in parts by weight):
[0015] Mix 73 parts of CaCl2 6H2O and 0.3 part of HEC (hydroxyethyl cellulose), add 0.5 parts of BaCO3 and 1 part of FeCl2, add to the reaction kettle, and heat to 1-3 parts higher than the melting point of CaCl2 6H2O (29.7°C). The temperature of ℃, that is, 31-33 ℃, makes it melt to the transparent liquid phase, and adds 0.1-1 times (note that it is a multiple) of the total weight of the above three components of porous mineral materials, specifically 15 parts by weight of diatomaceous earth, Fully stir evenly, heat-preserve and absorb for 4 hours, cool to a solid phase, discharge, and pulverize to a material with a particle size of 0.1mm-20μm for later use. Then carry out film coating, which can be compared with sequence 1 in Table 2, use 10 parts of paraffin, 80 parts of No. 200 solvent oil, heat to melt the paraffin, then add 10 parts by weight of p...
