▎ 摘 要
NOVELTY - Conductive cushioning material for new energy vehicles comprises 100 pts. wt. base material comprising silicone rubber, acrylic rubber, chloropropylene rubber, ethylene propylene diene monomer rubber, natural rubber, butadiene rubber and polyurethane rubber, 10-30 pts. wt. carbon fiber, 30-100 pts. wt. thermally conductive filler, 1-5 pts. wt. defoamer comprising physical defoamer or chemical defoamer, and 0.1-0.5 pt. wt. catalyst, where the chemical defoamer comprises platinum catalyst or organotin catalyst. USE - The conductive cushioning material is used in new energy vehicle power batteries. ADVANTAGE - The conductive cushioning material has low density, low compression set rate, excellent thermal conductivity, and simple preparation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of low-density thermally conductive cushioning material for new energy vehicles involving (i) mixing base material, carbon fiber, thermally conductive filler, foaming agent and catalyst in the mixer, controlled mixing temperature at 60 degrees C for 2 hours, (ii) calendering the mixture obtained in the step (i) into a sheet through a calendering device, where the thickness of the sheet is 0.5-5 mm, (iii) cutting the sheet obtained in the step (ii) into pieces with a cutting length of 500-1500 mm, (iv) superimposing the sheets cut in the step (iii) in a container of the same specification with a thickness of 50-500 mm, and applying a pressure of 0.5-3 MPa and maintaining the pressure for 4 hours, (v) cutting the cube obtained in the step (iv) twice based on to the calendering direction, with a cutting thickness of 0.5-3 mm, and (vi) placing the sheet obtained in the step (v) into an oven for solidification and foaming at 90-170 degrees C, solidifying and foaming for 10 minutes, taking it out and cooling it to normal temperature and leaving still for 2 hours, performing secondary curing at 90-170 degrees C for 20-120 minute to obtain a low-density thermally conductive buffer material for new energy vehicles.
