A heat-transfer joint sealing material is prepared through steps as follows: polyethylene glycol is dissolved, methacrylic acid, benzenediol and phenothiazine are added, the temperature is increased, concentrated sulfuric acid is added, the temperature keeps constant after being increased, nitrogen is introduced, the materials have the thermostatic reaction, and an esterification product is obtained after reduced pressure distillation and dehydration; the esterification product, acrylic acid, lauryl mercaptan and deionized water are mixed, and a material A is obtained; ammonium persulfate and the deionized water are mixed, and a material B is obtained; the deionized water is heated, the material A and the material B are titrated simultaneously, heat is preserved after titration, a product is naturally cooled, pH value of the product is regulated, and a bonding agent is obtained; a heat-transfer base material, an adhesive and an expanding agent are mixed, the bonding agent is added under the vacuum condition, filler is added after stirring, the mixture is repeatedly stirred and heated, and the heat-transfer joint sealing material is prepared. The joint sealing material can be used for joint sealing between heat exchange surfaces, so that directional transfer of heat between different interfaces and between different devices and facilities is realized, energy loss is reduced, and energy is saved; the joint sealing material has good insulation performance and hydrophobic performance and can be directly taken as the heat exchange surface after a casting mould is hardened, and special-shaped and irregular heat exchange surfaces are provided.
