Abstract: The present invention provides a solid addition-type diesel environmental protection anti-smoke additive and a method for preparing the same. The additive includes a solvent, vinyl ferrocene, and vinyl acetate. The method includes the following steps: under the condition that nitrogen is introduced to completely replace air, adding to a high-pressure reactor the solvent, vinyl ferrocene, vinyl acetate, and a free radical initiator; starting stirring to introduce a high-pressure vinyl monomer; polymerizing and synthesizing a free radical into a crude product of a diesel anti-smoke oxidant; under the condition of the constant temperature of a system, completing reaction when a pressure is not changed for 60 min; cooling down a reaction product to a room temperature and releasing the pressure to an atmospheric pressure to obtain the crude product; and performing atmospheric distillation for the crude product to remove a petroleum ether and an unreacted raw material from the crude product.
