Abstract

The invention discloses a preparation method of a flame-retardant anticorrosion coating for wood buildings, relating to the technical field of anticorrosion coatings. The preparation method comprisesthe following steps: dissolving glucose into water, carrying out hydrothermal reaction, drying the product, dispersing the product into water, adding silicon chloride, carrying out hydrothermal reaction, drying, calcining, dipping the calcined product into ACQ, drying, adding mixed acid, carrying out ultrasonic treatment, and drying, so as to obtain a material d; mixing the material d with polybasic acid, carrying out ultrasonic reaction, adding polyhydric alcohol and a catalyst, introducing nitrogen, carrying out fusion polymerization, adding 9,10-dihydroxyhexadecanoic acid for end capping reaction, and adding propylene glycol monoethyl ether and water, so as to obtain a modified polyester emulsion; adding amino resin, triethanolamine, tricresyl phosphate, zinc borate, a filler, other aids and deionized water into the modified polyester emulsion, and mixing, so as to obtain the flame-retardant anticorrosion coating. The water-based polyester coating prepared by virtue of the preparation method has excellent performance and very good insect prevention property, corrosion resistance and flame retardance, is high in coating film hardness and capable of resisting friction and does notsettle after being placed at the room temperature for one year.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a preparation method of a flame-retardant anti-corrosion coating for wooden buildings. Background technique [0002] With the improvement of people's living environment and the increasing awareness of environmental protection, more and more people begin to pursue more energy-saving and more comfortable green life. Wooden buildings are widely used in residential and other uses because of their inherent ecological characteristics It is favored by many advantages. However, as a natural organic material, wood has obvious biological characteristics and is easily attacked by bacteria, insects and other organisms. In addition, wood is also a flammable material. Therefore, it is very necessary to take anti-corrosion measures for wood. Coatings are an economical and effective way to enhance the anti-corrosion and flame-retardant properties of wood. [0003] As an importa...
