Multifunctional inorganic composite foam concrete modifier and preparation method thereof

Abstract

The invention discloses a multifunctional inorganic composite foam concrete modifier and a preparation method thereof. The multifunctional inorganic composite foam concrete modifier is prepared from inorganic functional material nano silicon powder, mineral powder, expansive quick-hardening cement, rubber powder, a water reducing agent powder and a water repellent powder. The preparation method comprises the following steps: sequentially adding all the materials into a stirrer in parts by weight, mechanically stirring while adding the raw materials, and uniformly mixing, thereby obtaining themultifunctional inorganic composite foam concrete modifier; and then mixing and foaming according to the ratio of 0.80 part of a master batch to 0.20 part of the multifunctional inorganic composite foam concrete modifier to prepare a high-performance foam concrete product. The compressive strength of the foam concrete added with the modifier reaches 1.45 times of the industrial standard, and the foam concrete has the advantages of light weight, hydrophobicity, no cracking, flame retardance, heat preservation and insulation, sound insulation, the same service life as a building main body structure and the like, and is simple to prepare and convenient to operate and produce.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to the technical field of building material additives. Background technique [0002] All countries in the world start building energy conservation by focusing on the innovation of building envelope materials. As early as the 1960s, some developed countries began to replace traditional wall materials with new wall materials with good thermal insulation performance and low production energy consumption. [0003] Although my country's building energy conservation work started late, it has been vigorously promoted. First-tier cities such as Beijing and Shanghai have required building energy conservation rates to be greater than 80%. With the comprehensive advancement of my country's building energy-saving work and building industrialization, traditional building wall materials obviously cannot meet the requirements of modern buildings, and a new generation of foam concrete se...

AI Technical Summary

Problems solved by technology

After ordinary foam concrete is added with the modifier of the present invention, it realizes light weight, ultra-high strength (the compressive strength reaches 1.45 times of the industry standard), thermal insulation, sound insulation, water repellency, no cracking, and the same life span as the main structure of the building, etc. Excellent quality, so that the foam concrete wall material overcomes the current shortcomings of low strength, poor waterproof, high thermal conductivity, easy to crack, etc.
