The invention relates to a high-buoyancy and high-elasticity life buoy. The life buoy is prepared from the following raw materials in parts by weight: 45-60 parts of an SEBS thermoplastic rubber, 8-12parts of an EPDM rubber, 12-18 parts of a POE rubber, 3-6 parts of a TPE rubber, 1-3 parts of color masterbatch, 2-5 parts of a calcium carbonate filler, 1-3 parts of pot clay, 6-10 parts of softening oil, 2-4 parts of a foaming agent, 1-2 parts of zinc oxide powder and 1-3 part of a cross-linking agent. The preparation method comprises the following steps: (1) respectively weighing the materials, adding into a mixer, stirring for 3-4 minutes at a temperature of 50-60 DEG C, transferring into a mixing mill, and mixing for 4-6 minutes at a temperature of 110-120 DEG C; (2) putting the mixed material into an open mill, and rolling into sheets; and (3) cutting a certain amount of the material sheets as required, putting the cut material sheets into a mold, carrying out hot pressing in a press vulcanizer at 170-180 DEG C under a pressure of 8-10 MPa for 8-10 min, opening the mold, cutting edges, and carrying out frosting treatment.

    本发明涉及一种高浮力高弹性救生圈,所述救生圈由以下重量份的原料制成:SEBS热塑性橡胶45~60,EPDM橡胶8~12,POE橡胶12~18,TPE橡胶3~6,色母1~3,碳酸钙填充剂2~5,陶土1~3,软化油6~10,发泡剂2~4,锌氧粉1~2,交联剂1~3。其制备方法如下:(1)将上述各物料分别称重后加入混料机中在50~60℃搅拌3~4min,移到混炼机中以110~120℃的温度混炼4~6min;(2)将混炼好的料投入到开炼机中辊压成片;(3)按需裁取一定量的料片放入模具,并在平板硫化机中热压,温度170~180℃,压力8~10MPa,热压8~10min,开模,裁边,磨砂处理。
