PURPOSE: Provided is a method for preparing thermoplastic rubber having superior heat resistance which is not deformed at high temperature of 110deg.C by crosslinking free radicals generated by incorporating vinyl methoxy silane, dicumyl peroxide, dibutyltin dilaurate, and anti-oxidant into raw rubber. CONSTITUTION: The thermoplastic rubber is prepared by (i) blending 0.1-15wt.% of vinyl methoxy silane, 0.01-0.02wt.% of dicumyl peroxide, 100wt.% of thermoplastic rubber, followed by grafting; (ii) blending 0.01wt.% of dibutyltin dilaurate, an effective amount of an anti-oxidant, and 100 wt.% of thermoplastic rubber; (iii) mixing 95 parts by weight of composition obtained in the step 1, and 5 parts by weight of a composition obtained in the step 2; (iv) crosslinking the composition at a temperature range of 160 to 180deg.C. In the method, deca bromo diphenyl and antimony oxides are added thereto for giving a fire-proofing property.
