Abstract

The invention discloses a composite board used for buildings. The composite board comprises the following components in parts by weight: 20-35 parts of ethylene vinyl acetate resin, 5-8 parts of gelatine powder, 15-25 parts of polystyrene foaming particles, 18-30 parts of glycerinum, 5-10 parts of silica sand, 2-5 parts of flame retardant, 1-3 parts of foaming agent and 5-8 parts of water. The composite board has the advantage of convenience in installation in the using process and a function of fire prevention due to the use of the fire retardant, the foaming agent improves the strength and tensile effect of the board and prolongs the service life of the board, and the silica sand and the glycerinum have a soundproof function.

Description

technical field [0001] The invention relates to a board, in particular to a composite building board. Background technique [0002] Traditional building materials, such as various fiber materials, foam materials, hollow glass materials, etc., are industrially produced inorganic or organic materials. The sound insulation material made of the above raw materials has the problems of not being fire-proof if it is heat-insulating, and having low strength if it is fire-proof. The existing building boards are cumbersome in the process of installation and use, and at the same time release strong toxic gas during the burning process, which is harmful to human health. [0003] Therefore, in order to solve the above problems, a new technical solution is provided to meet the demand. Contents of the invention [0004] The object of the present invention is to provide a composite building board. [0005] The technical scheme adopted in the present invention is: [0006] A composite ...
