A low-particle-release polyisoprene gasket for puncture, comprising the following raw materials in parts by weight: 100 parts of polyisoprene rubber, 1–10 parts of inorganic filler, 1–5 parts of plasticizer, 1–3 parts of antioxidant, 3–6 parts of colorant, 3–8 parts of vulcanization accelerator auxiliary, 0.1–3 parts of vulcanization accelerator, 1–5 parts of vulcanizing agent, and 0.5–10 parts of ultra-high molecular weight polyethylene. The preparation method of the low-particle-release polyisoprene gasket comprises the following steps: rubber compound mixing; sheeting; vulcanization molding; punching; extraction with alkaline aqueous solution; acid neutralization; pre-cleaning; fine cleaning; silicidation treatment and drying. The low-particle-release polyisoprene gasket has high self-lubrication, low resistance from the rubber gasket when punctured by an injection needle, reduces particle release during puncture, and avoids visible particles in the liquid medicine during infusion.
