Example Embodiment
[0016] The method for preparing the aforementioned durable elastic floating body includes the following steps:
[0017] Step 1. Mix ethylene-vinyl acetate copolymer, thermoplastic elastomer TPE, fillers, foaming aids, lubricants and pigments, and then add coupling agent modified anti-ultraviolet agent, coupling agent modified antioxidant and coupling agent. The mixture of linking agent modified antibacterial agents is blended and then smelted and pelletized to obtain the first pelletized material, wherein the banburying temperature is 50-80°C and the time is 10-15min;
[0018] Step 2. Blend and inject the first pelletized material, foaming agent and crosslinking agent to obtain a mother embryo, wherein the injection temperature is 80-100°C;
[0019] Step 3. Molding and foaming the mother embryo to obtain a durable elastic floating body, the foaming temperature is 165-180°C, and the time is 30-60 min.
[0020] It can be seen from the above description that the beneficial effects of the...
