Abstract

The invention specifically relates to a self-cleaning flame-retardant environment-friendly coating for timber architectures and a preparation method thereof, belonging to the technical field of environment-friendly functional coatings. According to the invention, polyurethane emulsion is used as a film forming substance; a fluorine silicon auxiliary agent containing a hydroxyl group is used as a hydrophobic auxiliary agent with low surface energy; a halogen-free flame-retardation system is composed of ammonium polyphosphate, aluminum hydroxide and zinc oxide; titanium dioxide, sericite, a wetting agent, a thickening agent, an antifoaming agent, a dispersant and a film forming auxiliary agent are additionally added; so the self-cleaning flame-retardant environment-friendly coating for timber architectures is prepared. The coating prepared in the invention has self-cleaning and flame-retardant functions and other functions, is widely applicable to timber architectures, protects the architectures and improves the living and working environments of people.

Description

technical field [0001] The invention belongs to the field of functional coatings, in particular to a self-cleaning, flame-retardant and environment-friendly coating for wooden structures and a preparation method. Background technique [0002] Wood has the characteristics of light weight, high strength, beautiful appearance, and good processing performance. It has been favored by people since ancient times and is an important class of building materials. Compared with reinforced concrete or brick and tile structure houses, wooden structure houses have the advantages of renewable raw materials, recyclable utilization, and green environmental protection. At the same time, wooden structures have good resistance to instantaneous impact and periodic fatigue damage, which makes wooden structures better able to resist natural disasters such as earthquakes. In addition, the use of wooden structure houses can protect the land, and the construction period of wooden structure buildings...
