preparation example Construction

[0028] The preparation method of the new energy vehicle battery potting material comprises the following steps:

[0029] S1. Put vinyl-terminated silicone oil, hexamethyldisilazane and white carbon black into the kneader, knead for 5-6 hours, add distilled water, raise the temperature to 150-170°C, and dehydrate under the condition of vacuum degree of 0.1-0.2MPa for 20 -50min, obtain base material;

[0030] S2. After mixing the modified epoxy resin, alumina, monoplatinum catalyst and halogen-free flame retardant, ultrasonically disperse, and then disperse evenly with a grinder to obtain material I;

[0031] S3. Put the base material, peroxide vulcanizing agent and reactive diluent RZ1021 into a kneader and mix evenly, and then disperse evenly with a grinder to obtain material II;

[0032] S4. Mix material I and material II evenly, and defoam under the condition of vacuum degree of 0.08-0.1 MPa for 1-2 hours to obtain the new energy vehicle battery potting material.
