Problems solved by technology

Some of these wall materials have good heat insulation performance but the wall core material is not resistant to high temperature, some have good heat insulation performance but not enough fire resistance, and some are heavy and inconvenient for installation and construction.
Without exception, the above materials have not achieved breakthroughs in high temperature resistance technology, so they cannot be widely used
Especially in terms of fire fighting, it seems powerless

Abstract

The invention discloses a magnesium oxychloride cement foam light wallboard and a preparation method as well as equipment. The two surfaces of the wallboard are made of a mixture of glass fiber cloth and magnesium oxychloride cement; the middle part of the wallboard is made of a magnesium oxychloride cement foam material; and the magnesium oxychloride cement foam material is mainly prepared from MgO, MgCl2 and H2O. The magnesium oxychloride cement foam light wallboard has the advantages of water prevention, thermal insulation, heat preservation, shock absorption, high temperature resistance, light weight, high strength and convenience in mounting and construction. Through the magnesium oxychloride cement foam light wallboard, the problem of over high load of a high-rise building can be solved; and the volume weight of the wallboard can be controlled to be below 500kg / cu.m, so that the load is greatly reduced. Through the wallboard, the problem that the building is warm in winter and cool in summer can be solved; and the wallboard has thermal insulation, heat preservation and excellent water-proof performance. The wallboard has two extremely smooth surfaces and can be directly usedas a decorative material.

Description

[0001] technical field [0002] The invention relates to the technical field of building materials, in particular to a magnesium oxychloride cement foamed lightweight wallboard, a preparation method and equipment. Background technique [0003] Nowadays, there are more and more high-rise buildings (more than 10 floors), how to effectively reduce the load of the building while maintaining the strength of the wall is the dream goal of countless people. However, there are severe cold in winter and intense heat in summer, so it is necessary to consume as little energy as possible and to satisfy people's warm and comfortable requirements to the greatest extent. Pursuing energy saving and emission reduction is the common goal of mankind. Fires are relentless, especially in high-rise buildings with more than ten floors, and fire ladders are difficult to reach to play a role in extinguishing fires. People hope to have wall materials that can not only prevent fire but also insulat...
