Abstract

The invention relates to a flame retardant plate for a building. The flame retardant plate for the building is characterized by being composed of the following ingredients in parts by mass: 33-56 parts of expanded perlite, 25-45 parts of magnesium oxide, 1-15 parts of cement, 3-6 parts of a foaming agent, 2-5 parts of copper sulfate liquid and 4-7 parts of triethanolamine. The flame retardant plate prepared by adopting the preparation method provided by the invention is low in production cost and excellent in water resistance. Combustion grade in flame retardant standard GB8624-2006 C grade and above can be met.

Description

technical field [0001] The invention relates to a building material, in particular to a building flame-retardant board. Background technique [0002] Foamed cement brick boards and hollow bricks used in non-load-bearing masonry products in the construction and decoration industries have a large specificity and poor sound insulation effect; Fracture, the above-mentioned products have a large proportion, and the construction is troublesome. Foam boards have poor fire resistance and low compressive strength. Contents of the invention [0003] The present invention proposes a building flame retardant board aiming at the above problems. [0004] The specific technical scheme is as follows: [0005] A building flame-retardant board, characterized in that the composition is as follows in parts by mass: 33-56 parts of expanded perlite, 25-45 parts of magnesium oxide, 1-15 parts of cement, 3-6 parts of foaming agent, sulfuric acid 2-5 parts of copper liquid, 4-7 parts of trieth...
