Problems solved by technology

The autoclaved aerated concrete block or plate made of autoclaved aerated concrete has the characteristics of low density, fire resistance, fire prevention, sound insulation, heat insulation and heat preservation. However, the building materials made of autoclaved aerated concrete are mechanically In terms of strength, it is difficult to reach the mechanical strength of other building materials such as stone and red bricks. Once natural disasters such as earthquakes occur, buildings made of autoclaved aerated concrete will be prone to collapse.

Abstract

The invention discloses polypropylene fiber autoclaved aerated concrete and a preparation method thereof. The method comprises the following steps: a) performing first mixing on oleic acid, triethanolamine and water to prepare soluble oil; b) performing second mixing on an aluminum source, a foaming agent and water to prepare an aluminum powder suspension; c) performing third mixing on alkali and water to prepare an alkaline solution; and d) performing fourth mixing on cement, slag, sand, polypropylene fiber, phenolic resin, red brick particles, ferriferrous oxide and water in the presence of a magnetic field with the magnetic field intensity of 0.002-0.003T, then adding the soluble oil, the alkaline solution and the aluminum powder suspension, performing fifth mixing, casting, and then aerating to prepare the polypropylene fiber autoclaved aerated concrete, wherein the aluminum source is aluminum powder or aluminum paste, the foaming agent is one or more of nekal, peregal, saponin powder, paraffin wax soap and washing powder, and alkali is sodium carbonate and / or borax. A building material prepared by using the polypropylene fiber autoclaved aerated concrete has excellent mechanical strength, density and freezing tolerance.

Description

technical field [0001] The invention relates to autoclaved aerated concrete, in particular to a polypropylene fiber autoclaved aerated concrete and a preparation method thereof. Background technique [0002] Autoclaved aerated concrete is a building material with cement, slag, silica sand, etc. as the main raw materials. The autoclaved aerated concrete block or plate made of autoclaved aerated concrete has the characteristics of low density, fire resistance, fire prevention, sound insulation, heat insulation and heat preservation, but the building materials made of autoclaved aerated concrete are mechanically In terms of strength, it is difficult to reach the mechanical strength of other building materials such as stone and red bricks. Once natural disasters such as earthquakes occur, buildings made of autoclaved aerated concrete will be prone to collapse. Contents of the invention [0003] The object of the present invention is to provide a polypropylene fiber autoclaved...
