Composite type foam concrete foaming agent and preparation method thereof

The invention discloses a composite type foam concrete foaming agent and a preparation method of the composite type foam concrete foaming agent. The foaming agent comprises the following components according to weight proportion: 25-45% of hydrogen peroxide, 1-2% of a foaming catalyst, 10-15% of a surfactant, 5-10% of a foam stabilizing agent and of the balance of water, wherein the volume percentage concentration of the hydrogen peroxide is 24-42%. The preparation method comprises the following steps of: adding the hydrogen peroxide, the surfactant and the foam stabilizing agent into water and agitating for 1-2 min; adding the foaming catalyst into a mixed solution; and uniformly agitating to obtain the concrete foaming agent. The composite type foam concrete foaming agent prepared by the invention has the advantages of long time for stabilizing foams, difficulty in generating mildewing and high foam strength.
