Abstract

The invention relates to the technical field of green building design, in particular to a manufacturing technology of an energy-saving environment-friendly building board and a green building material. By adopting a composite hot press molding technology, the composite material prepared from mineral fibers, magnesium hydroxide, phosphoric acid, expanded perlite, isocyanate propyltriethoxysilane, phenolic resin, epoxy resin, a plasticizer, hexamethylenetetramine and polyurethane is low in heat conductivity coefficient and obvious in energy-saving and noise-reducing effect, and becomes a basic guarantee that the total energy consumption of buildings in the whole society reaches the standard. The mineral fibers which are low in price and easy to obtain are adopted for enhancing the mechanical property of the building board, the compressive strength and the breaking strength are improved by 10-50 times, and the building board is firm, reliable and not prone to damage and fracture. The magnesium hydroxide inorganic flame retardant which is non-toxic, non-corrosive and excellent in stability is adopted so that the defect that the composite material using a halogen (such as bromine)-containing flame retardant can generate a large amount of toxic and corrosive gas and smoke in the combustion process is overcome.

Description

technical field [0001] The invention relates to the technical field of green building design, in particular to a manufacturing technology of energy-saving and environment-friendly building panels and green building materials. Background technique [0002] Architecture is a symbol of modern civilization. Green building materials play a very important role in the water and air balance, air purification, ecological balance, and natural ecological cycle of the urban living environment. As a common building material, building panels directly affect the quality of buildings. Comprehensive Building panels with excellent performance are an important requirement and guarantee for building quality. Organic thermal insulation materials have small thermal conductivity and good thermal insulation effect, but they are easy to burn. Once a fire occurs, the flame will spread faster and a large amount of toxic gas will be emitted. In addition, organic thermal insulation materials are not re...
