Abstract

The invention discloses a radiation-resistant external wall decoration board which is prepared from, by mass, 50 parts of magnesium sulfate heptahydrate solution with the Baume degree of 24-30 degrees, 25-35 parts of light calcined magnesia powder, 50-80 parts of barium sulfate, 5-10 parts of saw dust and 0.005-0.015 part of additive through room-temperature even mixing. The radiation-resistant external wall decoration board has the advantages of being free of scumming and moisture regaining, high in strength, long in service life, resistant to radiation and the like and has a wide application prospect by serving as a safe and environmentally-friendly radiation-resistant building external wall material.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a radiation-resistant exterior wall decorative board. Background technique [0002] Housing is an important indicator to measure a country's economy and people's living standards. The safety, durability, heat preservation and ease of construction of its building materials are important means to improve the quality of housing and improve the living environment. Lightweight, high-strength magnesium materials are increasingly used in contemporary buildings. [0003] Although magnesium materials have been widely used in the market at present, there are phenomena of returning moisture and halogen, which are corrosive to metals; after absorbing moisture, the mechanical strength decreases significantly, which affects the service life; the radiation resistance of the material is not strong, and electromagnetic radiation has Problems such as certain harm to human life and heal...
