Abstract

The invention belongs to the technical field of building materials and particularly relates to a foaming agent for hydrophobic foam concrete and a preparation method of the foaming agent. The foaming agent for the hydrophobic foam concrete is prepared from the following raw materials in parts by weight: 200-260 parts of a frother, 20-30 parts of a foam stabilizer, 1-2.5 parts of a thickener, 210-300 parts of an enhancer, 15-20 parts of a diluent, 1.5-2.5 parts of a preservative and 420-480 parts of water. The foaming agent for the hydrophobic foam concrete is good in stability of generated foams, good in foaming effect, high in closed pore ratio of generated foamed concrete, good in hydrophobicity and high in compressive strength.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a foaming agent for hydrophobic foamed concrete and a preparation method thereof. Background technique [0002] The porous material formed by mixing the foam prefabricated by the foaming agent and cement mortar evenly and hardening is foam concrete. The foaming agent is the key factor in the production of foamed concrete. However, the existing foam concrete has problems such as low foaming power and poor stability. [0003] Chinese patent CN104860574A discloses a foaming concrete foaming agent, which includes the following raw materials by weight: 6-10 parts by weight of aminosiloxane, 15-25 parts by weight of isopropanol, and 20-30 parts by weight of ethanolamine , 1.5-2 parts by weight of hydroxymethylpropyl cellulose, and 2500-3000 parts by weight of water. The foaming agent of the present invention is used directly in the foaming process without dilut...
