Abstract

The invention discloses a method for preparing water-based fireproof anticorrosive paint by filling aluminum tripolyphosphate-expanded vermiculite-water glass, and the method comprises the following steps: adding aluminum tripolyphosphate and modified nano zinc oxide into a sodium chloride solution, stirring to dissolve, filling into a polyethylene bag, sealing, putting into a gamma ray radiationfield, and carrying out radiation modification treatment; cleaning vermiculite with water, drying, putting into a crucible, calcining in a muffle furnace at high temperature to obtain expanded vermiculite, uniformly mixing the expanded vermiculite with water glass in equal mass, pouring into a stirrer, and uniformly stirring to obtain an expanded vermiculite-water glass composite flame-retardant system; uniformly mixing the phase change heat absorption expansion flame-retardant fireproof system with aluminum hydroxide and boric acid, putting the mixture into a ball milling tank, adding physically-chemically modified aluminum tripolyphosphate and the expanded vermiculite-water glass composite flame-retardant system, uniformly stirring, carrying out ball milling, uniformly dispersing, addingsilicone acrylic emulsion and a defoaming agent, uniformly stirring, and continuously carrying out ball milling to obtain the water-based fireproof anticorrosive paint.

Description

technical field [0001] The invention belongs to the field of water-based coatings, and in particular relates to a method for preparing water-based fireproof and anticorrosion coatings by filling aluminum tripolyphosphate-expanded vermiculite-water glass. Background technique [0002] Steel structure is a fast-growing building structure. The steel structure itself has the characteristics of light weight, high strength, easy construction and recycling, and is widely used in the construction field. Steel structure buildings also have obvious disadvantages. Steel itself does not burn, but as a metal, it has good thermal conductivity. When a fire breaks out, it only takes more than ten minutes to reach the critical temperature of the steel itself, and the bearing capacity of the steel is weakened sharply, causing The collapse of buildings caused casualties and economic losses. Therefore, it is necessary to improve the fire resistance limit of steel and effectively protect it. ...
