Magnesium oxychloride foam fireproof concrete lightweight wall composite material and preparation method thereof

Abstract

The invention discloses a magnesium oxychloride foam fireproof concrete lightweight wall composite material and a preparation method thereof, and belongs to the field of building materials. The composite material comprises a bottom layer and a surface layer; the bottom layer is prepared from, by weight, 10-20 parts of magnesium chloride, 4-6 parts of magnesium oxide, 2-8 parts of water, 0.1-0.2 part of phosphoric acid, 4-8 parts of ceramsite, 3-8 parts of a filler, 0.1-0.2 part of inorganic glass reinforced plastic fibers, 0.1-0.2 part of a liquid polycarboxylate-type water reducing agent and0.1-0.2 part of hydrogen peroxide; the surface layer is prepared from, by weight, 10-20 parts of magnesium chloride, 4-6 parts of magnesium oxide, 2-8 parts of water, 0.1-0.2 part of phosphoric acid,3-8 parts of a filler, 0.1-0.2 part of inorganic glass reinforced plastic fibers, 0.1-0.2 part of a liquid polycarboxylate-type water reducing agent and 0-0.2 part of a toner. The magnesium oxychloride cement foam ceramsite fireproof sound-insulation concrete lightweight wall composite material has the advantages of light weight, high strength, fireproof performance, heat preservation, sound insulation and the like and is an environment-friendly sound absorbing and insulating material; the preparation method of the sound absorbing ceramic material is low in cost, short in consumed time and easy to implement.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a magnesium oxychloride cement foam ceramsite fireproof and soundproof concrete lightweight wall composite material, in particular to a magnesium oxychloride foam fireproof concrete lightweight wall composite material and a preparation method thereof. Background technique [0002] There are various types of enclosure materials for substation assembly buildings, each with its own advantages, but at the same time, they all have obvious performance shortcomings. The commonly used single-layer color steel plate has poor thermal insulation performance, roof waterproofing cannot be guaranteed, and the service life cannot meet the same service life requirements as the main structure; the use of sandwich panels cannot meet the same service life requirements as the main structure, and the sandwich panels as It is difficult to replace the roof panels in the later stage; although the double-...

AI Technical Summary

Problems solved by technology

[0004] In view of the fact that the existing magnesium oxychloride cement foam concrete production focuses on improving the water resistance of magnesium oxychloride cement products, while ignoring its light weight characteristics, the product has a high bulk density, heat insulation and sound absorption effects are poor, and production The problem of high cost, the purpose of the present invention is to provide a magnesium oxychloride foam fireproof concrete lightweight wall composite material and its preparation method, the obtained composite material can be widely used in wall fire prevention, wall sound insulation, wall decoration
