Foaming agent

Abstract

The invention discloses a foaming agent. The foaming agent is prepared from the following raw materials in parts by weight: 2 to 5 parts of aluminum powder, 1 to 5 parts of sodium lauryl sulfate, 5 to10 parts of water glass, 3 to 5 parts of silicon carbide, 1 to 3 parts of carbonate, 0.1 to 0.5 part of ammonium nitrite, 0.1 to 0.3 part of ammonium carbonate, 10 to 15 parts of petroleum ether, and1 to 3 parts of dichlorodifluoromethane. The foaming agent proposed by the invention has strong foaming capacity, large foam quantity per unit volume, and stable foam, has good compatibility with a use media, is non-corrosive to the cement and metal, has short degradation time, is easy to recycle, has strong flame retardant, has no pollution to the environment, and is easy to transport.

Description

technical field [0001] The invention belongs to the field of engineering materials, in particular to a foaming agent. Background technique [0002] Foaming agents are any surfactants or surface-active substances whose aqueous solutions are capable of generating foam in large quantities when air is introduced. The foaming agent has high surface activity, can effectively reduce the surface tension of the liquid, and arrange the double electron layers on the surface of the liquid film to surround the air, forming bubbles, and then the bubbles form foam. Because most surfactants and surface-active substances have a large amount of foaming ability, foaming agents contain most surfactants and surface-active substances. [0003] The existing foaming material has a long degradation time and is difficult to recycle, which causes great pollution to the environment. Contents of the invention [0004] The object of the present invention is to propose a kind of easily degradable foam...
