Description

technical field [0001] The invention relates to a foaming agent, in particular to a hydroxyl compound compound foaming agent and a preparation method thereof. Background technique [0002] With the reform of wall materials and the implementation of building energy-saving policies in my country, the development and application of energy-saving building materials have received extensive attention. The country has vigorously developed new materials such as energy-saving, waste utilization, heat preservation, light weight, and heat insulation. Among them, foam concrete blocks occupy an important position in non-load-bearing wall materials. Foamed concrete has many advantages such as light weight, heat insulation, sound insulation and fire resistance, and good seismic performance. It has been widely used abroad, and it has developed rapidly in China in recent years. Foam concrete is usually made by mechanically preparing foaming agent aqueous solution into foam, and then adding ...
