The radioresistant joint mixture accelerant is characterized by being prepared from, by mass, 2 parts to 3 parts of ethylene-vinyl acetate copolymers, 8 parts to 12 parts of hole-formed expanded perlite, 2 parts to 2.4 parts of organosilicon flatting agents, 1 part to 1.5 parts of acrylic resin, 3 parts to 6 parts of hydroxypropyl methyl cellulose, 1 part to 1.3 parts of inorganic aluminum salt water-proof agents, 0.5 part to 1.5 parts of magnesium aluminum silicate, 1.5 parts to 1.9 parts of RTV organic silica gel and 5 parts to 8 parts of 400-mesh barite powder. A preparing method includes the steps that the ethylene-vinyl acetate copolymer and the acrylic resin are dispersed through ultrasonic waves for 0.5 h to 1 h, then the organosilicon flatting agents, the inorganic aluminum salt water-proof agents, the magnesium aluminum silicate, the 400-mesh barite powder and the RTV organic silica gel are added, the mixture is rapidly stirred and dispersed for 1 h to 1.5 h, finally the hole-formed expanded perlite and the hydroxypropyl methyl cellulose are added, and the temperature of the mixture is slowly reduced to the indoor temperature.
