Problems solved by technology

The formula and process of this invention are classic and traditional, but it uses a large number of raw materials, and the fire resistance of the obtained product is single. etc.), to accelerate the aging of wood, at this time the fire retardant coating is unable to resist fire
[0005] As more and more attention is paid to the fire protection of ancient buildings, performance-based fire protection design has become the development trend of building fire protection design. It is a comprehensive fire protection strategy, which can make full use of various technologies and improve the utilization rate of equipment and personnel. , but it is undeniable that performance-based design, as an emerging technology, is not yet mature enough, and the social environment and technical conditions are not yet ready for the promotion and application of this technology
Therefore, there is currently a lack of modified fireproof coatings that can still maintain excellent fireproof performance in harsh environments

Abstract

The application of the invention discloses waterborne transparent fireproof coating for ancient building wood, made from, by weight, 3-15 parts of a carbided catalyst, 2-10 parts of a purging agent, 2-10 parts of a carbonizing substance, 15-30 parts of ammoniacal copper quaternary, 1-2 parts of UV-531 antiaging agent, 2-4 parts of a synergist, and 65-93 parts of water; a preparation method of thewaterborne transparent fireproof coating for ancient building wood comprises the steps of 1) weighing; 2) preparing guanidine phosphate crystal; 3) grinding the guanidine phosphate crystal, and dryingin vacuum to obtain guanidine phosphate powder; 4) adding the carbonizing substance, ammoniacal copper quaternary and antiaging agent to the guanidine phosphate powder, adding water, and stirring fordissolving to obtain the coating. The waterborne transparent fireproof coating for ancient building wood can keep excellent fireproof performance in ancient building wood in a severe environment.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a water-based transparent ancient building wood fireproof coating and a preparation method thereof. Background technique [0002] Wood is a combustible material and presents a high fire hazard. Wood fire retardant paint is a special paint that is applied on the surface of wood substrates to reduce the flammability of the wood surface, retard the rapid spread of fire, and improve the fire resistance limit of wood. The buildings of traditional wooden structure relics are important historical and cultural heritage, and also the precious wealth of all mankind. However, due to the limitation of historical conditions, the fire prevention infrastructure of wooden structures is weak, and it is extremely easy to be destroyed by fire. It is self-evident that transparent fireproof coatings are ideal for fire protection of ancient buildings. For those ancient buildings that have a str...
