Magnesium oxychloride wall

Abstract

The invention provides a magnesium oxychloride wall. The magnesium oxychloride wall is prepared from raw materials in parts by weight as follows: 80-100 parts of magnesium chloride, 50-70 parts of magnesium oxide, 5-20 parts of fly ash, 6-12 parts of perlite, 5-10 parts of quartz sand, 5-20 parts of tetra calcium aluminoferrite, 5-20 parts of maize straw, 1-10 parts of a stearic acid-polyvinyl alcohol emulsion, 3-5 parts of phosphorus slag powder, 5-10 parts of graphite powder, 1-5 parts of talc powder, 2-6 parts of ferrous sulfate, 1-4 parts of 307 resin, 5-10 parts of sawdust, 1-2 parts of polypropylene fibers and 5-12 parts of silicon carbide whiskers. According to the raw material formula of the wall, magnesium chloride and magnesium oxide are used as the main raw materials and matched with various functional components, and all the components are matched for use as a whole, so that the prepared magnesium oxychloride wall has excellent performance such as high strength, heat resistance, water resistance, heat insulation, freezing resistance, corrosion resistance, acid and alkali resistance and avoidance of efflorescence.

Description

technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to. Background technique [0002] With the rapid development of my country's economic construction, people's demand for infrastructure materials such as cement and wood is increasing day by day. This makes energy crisis, environmental pollution and other issues more and more serious. Magnesium oxychloride products have attracted widespread attention due to their light weight, high strength, low alkalinity, corrosion resistance, impact resistance, easy molding, simple production process, low cost, low energy consumption, and environmental friendliness. Magnesium oxychloride products are a kind of air-hardening cementitious material (commonly known as magnesium oxychloride cement) obtained by two-component mixing of activated magnesia and industrial magnesium chloride solution, adding fibers such as glass fiber cloth as reinforcing materials, and adding various ...
