Abstract

The invention discloses an energy-saving gypsum board. The energy-saving gypsum board is characterized by comprising the following raw material: 48 parts of gypsum, 17 parts of sodium salt slag with aparticle size of less than 2mm, 11 parts of silica fume, 4 parts of zeolite powder, 0.5 part of a superplasticizer, and 19.5 parts of water. The gypsum board is subjected to phenolic resin infiltration treatment. The energy-saving gypsum board provided by the invention has the advantages of good mechanical properties, green and environmental protection.

Description

technical field [0001] The invention relates to a gypsum board, in particular to an energy-saving gypsum board. Background technique [0002] Sodium salt slag has not been fully developed and utilized, which pollutes the environment and increases the environmental load. Therefore, the development and utilization of these slags to make them resources has become a major issue in environmental governance today. The traditional building materials industry is facing new opportunities and challenges. Gypsum board is one of the most widely used building materials at present, and gypsum as one of the cementing materials is a traditional high-energy-consuming industry. To maintain the sustainable development of gypsum materials, reducing the amount of gypsum in cementitious materials is an effective method. Therefore, partially replacing the amount of gypsum with sodium salt slag will certainly reduce the pressure on the environment and energy. In addition, the flexural performanc...
