Use of stabilizers for stabilizing a foam, foaming agent, process for producing an air-entrained building material and air-pore-containing building materials and construction products obtainable by the processes

摘要

A foaming agent for the foaming of a binder lime or a building material mash for the production of air pore-containing building materials, in particular filling, lightweight and insulating materials, consists of a) 0.1 to 65.0 wt .-% of ionic, preferably anionic, foam-forming surfactant; b) from 0.05% to 9.0% by weight of at least one room temperature solid compound ELF-HG selected from the group consisting of ethoxylated long-chain fatty alcohols, ethoxylated natural resins, ethoxylated artificial resins and ethoxylated glycols; c) 0 to 9.0 wt .-% fatty alcohol having a chain length of C10 to C18, preferably from C12 to C16; d) 0.1 to 60.0% by weight of solvent selected from the group vicinal diols having 1 to 6 carbon atoms, diethylene glycol, triethylene glycol and diethylene glycol ethers; e) 0 to 20% by weight of organic additives; f) 0 to 20% by weight of pH regulators; g) 0 to 99.75% by weight of water, the mixture giving a total of 100% by weight.
