Embodiment 1

[0020] An embodiment of the present invention provides a composite foaming agent, including the following raw materials in parts by weight: 70 parts of triterpene saponins, 12 parts of sodium lauryl sulfate, 5 parts of foam-increasing components, 4 parts of foam-stabilizing components, functional components Divide into 2 parts and 10 parts of water.

[0021] Triterpene saponins are extracted from jujube leaves, hawthorn leaves, wild cotton leaves or American ginseng stems and leaves. Red date leaves, hawthorn leaves, wild cotton leaves or American ginseng stems and leaves are all low-cost raw materials, and triterpene saponins are extracted from this, which can Effectively reduce the production cost of the blowing agent.

[0022] The foam-increasing component is composed of the following materials in parts by weight: 11 parts of sodium lauryl polyoxyethylene ether sulfate, 10 parts of lauryl dimethyl amine oxide, and 12 parts of sodium decyl sulfate. The foam-increasing compon...

Embodiment 2

[0029] The embodiment of the present invention provides a composite foaming agent, including the following raw materials in parts by weight: 72 parts of triterpene saponins, 14 parts of sodium lauryl sulfate, 6 parts of foam-increasing components, 6 parts of foam-stabilizing components, functional groups Divide into 4 parts and 11 parts of water.

[0030] Triterpene saponins are extracted from jujube leaves, hawthorn leaves, wild cotton leaves or American ginseng stems and leaves. Red date leaves, hawthorn leaves, wild cotton leaves or American ginseng stems and leaves are all low-cost raw materials, and triterpene saponins are extracted from this, which can Effectively reduce the production cost of the blowing agent.

[0031] The foam-increasing component is composed of the following materials in parts by weight: 12 parts of sodium lauryl polyoxyethylene ether sulfate, 11 parts of lauryl dimethyl amine oxide, and 11 parts of decyl sodium sulfate. The foam-increasing component...

Abstract

The invention provides a composite foaming agent and a preparation method thereof, and relates-the technical field of foaming agents. The composite foaming agent comprises the following raw materials in parts by weight: 65-75 parts of triterpenoid saponin, 10-15 parts of lauryl sodium sulfate, 3-7 parts of a foam increasing component, 4-7 parts of a foam stabilizing component, 2-4 parts of a functional component and 8-11 parts of water. Triterpenoid saponin and lauryl sodium sulfate are used as foaming agent base materials, foam increasing components such as lauryl polyoxyethylene ether sodium sulfate, lauryl dimethyl amine oxide and decyl sodium sulfate and foam stabilizing components such as triethanolamine, sodium chloride and hydroxyethyl cellulose are added, and the foamability and foam stability of the foaming agent can be greatly improved; and meanwhile, tris(2, 3-dibromopropyl)isocyanurate is added into the foaming agent-serve as a flame-retardant functional component, and benzoic acid and isothiazolinone are added to serve as anti-corrosion functional components, so that the performance of the foaming agent is more perfect, and the foaming agent is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of foaming agents, in particular to a composite foaming agent and a preparation method thereof. Background technique [0002] Foamed concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then go through the pumping system of the foaming machine for cast-in-place construction or mold molding. A new type of lightweight insulation material containing a large number of closed pores formed by curing, and foam concrete foaming agent, also known as cement foaming agent, foam concrete foaming agent refers to the ability to reduce the surface tension of the liquid and produce a large amount of uniform and stable Foam is an admixture used to produce foam concrete. Foam concrete foaming agent is a kind of substance that can make its aqueous solution produce a large amount of foam when mechanical force is introduced...
