Embodiment 1
[0024] The one-time molding vulcanization process of the hollow rubber product of the present embodiment comprises the following steps:
[0025] Step 1, using the coating extrusion process to prepare rubber-coated rods; as figure 1 As shown, the rubber-coated rod consists of a rod core 1 and a rubber coating layer 2 coated on the rod core 1. The material of the rod core 1 is a phase change material, which is mixed with the following raw materials in weight percentage Uniformly made: 7% boron trioxide, 20% aluminum hydroxide, 17% sodium nitrate, 30% paraffin wax, 3% silicon dioxide, 5% talc, 6% rosin, 4% liquid coumarone, hard 2% fatty acid, 6% calcium carbonate, the phase change material is solid at room temperature, and the phase change temperature is 120°C; the rubber is EPDM rubber;
[0026] Step 2. Remove part of both ends of the rod core 1 of the rubber-coated rod described in step 1 (the removal length is about 100mm-200mm), fill it with rubber compound, and embed the a...

[0031] The one-time molding vulcanization process of the hollow rubber product of the present embodiment comprises the following steps:
[0032] Step 1, using the coating extrusion process to prepare rubber-coated rods; as figure 1 As shown, the rubber-coated rod consists of a rod core 1 and a rubber coating layer 2 coated on the rod core 1. The material of the rod core 1 is a phase change material, which is mixed with the following raw materials in weight percentage Uniformly made: boron trioxide 5%, aluminum hydroxide 22%, sodium nitrate 15%, solid paraffin 35%, silicon dioxide 2%, talc 3%, rosin 5%, liquid coumarone 4%, hard 1% fatty acid, 8% calcium carbonate, the phase change material is solid at room temperature, and the phase change temperature is 150°C; the rubber is EPDM rubber;
[0033] Step 2. Remove part of both ends of the rod core 1 of the rubber-coated rod described in step 1 (the removal length is about 100mm-200mm), fill it with rubber compound, and embed the...
Embodiment 3
[0038] The one-time molding vulcanization process of the hollow rubber product of the present embodiment comprises the following steps:
[0039] Step 1, using the coating extrusion process to prepare rubber-coated rods; as figure 1 As shown, the rubber-coated rod consists of a rod core 1 and a rubber coating layer 2 coated on the rod core 1. The material of the rod core 1 is a phase change material, which is mixed with the following raw materials in weight percentage Uniformly made: boron trioxide 8%, aluminum hydroxide 18%, sodium nitrate 20%, solid paraffin 25%, silicon dioxide 4%, talc 7%, rosin 7%, liquid coumarone 3%, hard 3% fatty acid, 5% calcium carbonate, the phase change material is solid at room temperature, and the phase change temperature is 135°C; the rubber is EPDM rubber;
[0040] Step 2. Remove part of both ends of the rod core 1 of the rubber-coated rod described in step 1 (the removal length is about 100mm-200mm), fill it with rubber compound, and embed the...
