The invention relates to a halogenated butyl rubber plug, in particular to a halogenated butyl rubber plug for injection and a preparation process of the halogenated butyl rubber plug. The halogenated butyl rubber plug for the injection is prepared from the following raw materials in parts by weight: 110 parts of halogenated butyl rubber, 50-70 parts of calcined kaolin, 10-30 parts of talcum powder, 5-10 parts of amorphous silicon dioxide synthesized by a precipitation method, 3-5 parts of alkylbenzene disulfide resin, 2-5 parts of zinc oxide, 2-5 parts of magnesium oxide, 2-3 parts of titanium dioxide and 0.1-0.5 part of carbon black. The composite material has the advantages of excellent gas/vapor permeability, chemical agent and solvent resistance, ozone resistance, weather resistance, thermal stability, small compression deformation and good biological inertness, and various performance tests meet related standard requirements. 本发明涉及一种卤化丁基胶塞，特别涉及一种注射液用卤化丁基橡胶塞及其制备工艺。本发明所述的注射液用卤化丁基橡胶塞，以重量份数计，原料组成如下：卤化丁基橡胶11
