Embodiment 1
[0056] A silica gel wave-absorbing material for high-frequency welding provided in this embodiment, in parts by mass, includes: 100 parts of silicone rubber; 8 parts of reinforcing agent; 3 parts of coupling agent; 10 parts of vulcanizing agent; 400 parts Absorbent.
[0057] Its preparation method is as follows:
[0058] S1. Surface-treat the wave-absorbing agent with a coupling agent, and then stir the wave-absorbing agent treated with the coupling agent with the silicone rubber;
[0059] S2. Stir the mixture obtained by stirring with the remaining raw materials until they are evenly mixed;
[0060] S3. The mixture obtained by uniform mixing is poured into a calender to be calendered and solidified to obtain a silica gel wave-absorbing material. The specific conditions for calendering and curing are: curing at a temperature of 150°C for 5 minutes;
[0061] S4. Winding up the silica gel absorbing material by a winding machine.
Embodiment 2
[0063] A silica gel wave-absorbing material for high-frequency welding provided in this embodiment, in parts by mass, includes: 200 parts of silicone rubber; 1 part of reinforcing agent; 15 parts of coupling agent; 0.8 parts of vulcanizing agent; 900 parts Absorbent.
[0064] Its preparation method is as follows:
[0065] S1. Surface-treat the wave-absorbing agent with a coupling agent, and then stir the wave-absorbing agent treated with the coupling agent with the silicone rubber;
[0066] S2. Stir the mixture obtained by stirring with the remaining raw materials until they are evenly mixed;
[0067] S3. The mixture obtained by uniform mixing is poured into a calender to be calendered and solidified to obtain a silica gel wave-absorbing material. The specific conditions for calendering and curing are: curing at 150°C for 15 minutes;
[0068] S4. Winding up the silica gel absorbing material by a winding machine.
Embodiment 3
[0070] A silica gel wave-absorbing material for high-frequency welding provided in this embodiment, in parts by mass, includes: 150 parts of silicone rubber; 5 parts of reinforcing agent; 10 parts of coupling agent; 5 parts of vulcanizing agent; 600 parts Absorbent.
[0071] Its preparation method is as follows:
[0072] S1. Surface-treat the wave-absorbing agent with a coupling agent, and then stir the wave-absorbing agent treated with the coupling agent with the silicone rubber;
[0073] S2. Stir the mixture obtained by stirring with the remaining raw materials until they are evenly mixed;
[0074] S3. The mixture obtained by uniform mixing is poured into a calender to be calendered and solidified to obtain a silica gel wave-absorbing material. The specific conditions for calendering and curing are: curing at 150°C for 10 minutes;
[0075] S4. Winding up the silica gel absorbing material by a winding machine.
