An anti-blazing method of automotive SCR(Selective Catalytic Reduction) is provided to prevent the SCR from being blazed due to oxidation reaction heat of the hydrocarbon by controlling the regeneration temperature of a CPF(Catalyzed Diesel Particulate Filter) according to the amount of the hydrocarbon. An anti-blazing method of automotive SCR comprises: a step for setting up adsorption quantity of the hydrocarbon in which the blazing of the SCR starts as reference value and comparing actual hydrocarbon adsorption amount of the SCR with the reference value; and a step for heating a CPF filter through a mapping normal mode in case the actual hydrocarbon adsorption amount is less than the reference value and gradually heating the CPF filter through a mapping delay mode.
