[0031] A kind of preparation method of the organosilicon foam gasket that is used for power battery case packaging of the present invention, such as figure 1 shown, including the following steps:
[0032] S1, silicone injection;
[0033] S2, pretreatment;
[0034] S3, parameter setting;
[0035] S4, dispensing and curing.
Embodiment 1
[0037] Embodiment 1, a method for preparing a silicone foam gasket used for encapsulation of a power battery box includes the following steps:
[0038] S1. Put the battery box to be packaged on the workbench; transport the prepared organic silica gel A and organic silica gel B to channel A and channel B respectively, and the mass ratio of the two components is A:B=1 :20.
[0039] S2. Set the working temperature of the pretreatment to 10° C. for 2 hours.
[0040] S3. Set the glue dispensing parameters, wherein the walking speed is 0.5m / min, the glue dispensing temperature is 10°C, and the glue spouting amount of the machine head is 0.5g / s.
[0041] S4. Start the dispensing machine, and mix the organic silica gel A and the organic silica gel B at a speed of 500rpm, so that the two components of the organic silica gel are fully mixed, and the glue mixing process is completed; the mixed glue is extruded from the machine head, along the Glue is dispensed at the junction of the ba...
