Description

Technical Field

[0001] The utility model relates to the technical field of magnesium oxychloride boards, in particular to a structure of a polyurethane composite magnesium oxychloride board. Background Technique

[0002] Magnesium oxychloride board fireproof materials are widely used in the fields of construction and interior decoration. The main components of this material are a ternary system formed by magnesium oxide, magnesium chloride / magnesium sulfate, and water, and it is a magnesium-based cementitious material with stable performance made by configuration and adding modifiers. It is a new non-combustible decorative material composed of a medium-alkaline glass fiber mesh as the reinforcing material and a lightweight material as the filler. However, the overall structural strength of the existing single-layer magnesium oxychloride board is low and the heat preservation effect is average.

[0003] The patent with the authorization announcement number CN205522745U discloses a magnesium oxychloride board, which includes a magnesium oxychloride board body. Three layers of grid-type high-silica low-alkali glass fibers are evenly arranged inside the magnesium oxychloride board body. The magnesium oxychloride board body is made of sawdust, magnesium oxide, and perlite mixed in a ratio of 1:3:1. Anticorrosion coatings are provided on the upper and lower surfaces of the magnesium oxychloride board body. The anticorrosion coating is made of melamine resin and polyurethane resin mixed in a mass ratio of 1:1. A solid wood strengthening skeleton is arranged between the glass fiber and the magnesium oxychloride board body. It enhances the strength by arranging a solid wood strengthening skeleton inside the magnesium oxychloride board body. Although it can increase the strength of the magnesium oxychloride board, it uses a solid wood skeleton. Limited by the thickness of the magnesium oxychloride board, the thickness of the solid wood skeleton is thin, and the strength increase is limited, and its heat preservation effect is average.
