Problems solved by technology

The application of foaming agents in my country is later than that of foreign countries. After decades of development, the comprehensive performance of foaming agents has been greatly improved compared with the early rosin foaming agents, but it is comparable to the international advanced foaming agents. However, there is still a large gap in terms of foamability and thermal stability, and the development level of foaming agents has gradually failed to meet the development needs of my country's foam concrete market.

Description

Technical field [0001] The invention relates to a foaming agent, in particular to an ether alcohol composite foaming agent and a preparation method thereof. Background technique [0002] In recent years, my country is vigorously implementing the building energy conservation policy, developing green buildings and circular economy, and realizing the greening of building materials will be an important development direction in the future. Construction projects have put forward new requirements for the use of concrete. Foamed concrete is a kind of lightweight concrete with a large number of closed pores inside, which is a kind of lightweight concrete with a large number of closed pores, which is energy-saving, heat-preserving, heat-insulating, lightweight, and fire-resistant. Compared with the organic thermal insulation material with polystyrene board as the main material, foam concrete has better fire resistance, durability, sound insulation and other properties. [0003] There are ma...
