Embodiment 1
[0043] A kind of elastic soft rubber, the elastic soft rubber is made of the following components by weight percentage:
[0044] Simethicone oil: 21%;
[0045] Ultrafine calcium carbonate: 7%;
[0046] Boric acid: 1%;
[0047] TPR: 25%;
[0049] Silicone resin: 15%;
[0050] Bentonite: 8%;
[0051] Barium carbonate: 3%;
[0052] Linseed oil: 15%;
[0053] Erucamide: 3%.
[0054] The silicone resin is an organic silicon resin with a softening point between 80°C and 160°C.
[0055] The preparation method of this elastic soft glue comprises the following steps:
[0056] (1) Mix simethicone, TPR and linseed oil, and heat the mixture to 100°C, 100°C
[0057] (2) Heat the silicone resin to 160-165°C to melt it, then add it to the mixed liquid in step (1), stir for 2-5 hours, and keep the temperature of the mixed liquid between 100-115°C between. Choose a silicone resin with a softening point between 80 and 160°C. This silicone resin can be com...
