Abstract
The invention discloses a method for preparing a doping type carbon dioxide absorbing agent for a vehicle. The method includes the steps that acrylamide and a first part of acrylic acid are dissolved in deionized water and react under catalysis of sodium bicarbonate powder so that a first reagent can be prepared, then the first reagent, remaining acrylic acid and 2-hydroxyethylamine react, and sodium chloride and ammonium bicarbonate are added. The prepared doping type carbon dioxide absorbing agent can effectively absorb carbon dioxide, is free of toxin and harmless, does not corrode other objects in the environment, and can be used in the vehicle easily.
