Problems solved by technology

[0003] Although magnesia boards have been widely used in the market at present, there are phenomena of returning moisture and brine, which are corrosive to metals; after absorbing moisture, the mechanical strength decreases significantly, which affects the service life; the ability of the board is not strong, and electromagnetic radiation is harmful to human life. Certain hazards to health and other issues need to be resolved urgently to improve performance, otherwise it will face the crisis of affecting development and use, or even being eliminated

Abstract

The invention discloses a formaldehyde-free inner wall decoration board. The formaldehyde-free inner wall decoration board comprises, by mass, 50 parts of magnesium sulfate heptahydrate solution with baume degree being 24-30 degrees, 25-35 parts of light calcined magnesia powder, 1-5 parts of negative ion powder, 5-10 parts of sawdust and 0.005-0.015 part of additive. The formaldehyde-free inner wall decoration board is produced by evenly mixing the materials above under normal temperature. The formaldehyde-free inner wall decoration board is free of scumming, free of moisture regaining, high in strength, long in service life, capable of achieving A-level fireproof performance, capable of generating negative oxygen ions and the like and is promising in application prospect when being used as a safe and environment-friendly building inner wall board.

Description

technical field [0001] The invention belongs to the technical field of building panels, in particular to a formaldehyde-free interior wall decorative panel. 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 panels are important means to improve the quality of housing and improve the living environment. Lightweight, high-strength magnesium panels are increasingly used in contemporary buildings. [0003] Although magnesia boards have been widely used in the market at present, there are phenomena of returning moisture and brine, which are corrosive to metals; after absorbing moisture, the mechanical strength decreases significantly, which affects the service life; the ability of the board is not strong, and electromagnetic radiation is harmful to human life. Health problems such as certain hazards need to be resolved urg...
