Anticorrosion water-based ultrathin fireproof paint for steel structures

Abstract

The invention discloses anticorrosion water-based ultrathin fireproof paint for steel structures. The anticorrosion water-based ultrathin fireproof paint comprises water-based silicone acrylic emulsion, water-based polyurethane emulsion, vinyl chloride-vinylidene chloride copolymer emulsion, chloric ether resin, water-based epoxy resin, aluminum triphosphate, pentaerythritol, melamine, zinc borate, trioxyde d'antimoine, zinc oxide, aluminum hydroxide, zinc phosphate, phosphorus-nitrogenous flame retardants, ceramic hollow micro-spheres, kaolin, mica powder, titanium dioxide, chlorinated rubber, thickeners, defoaming agents, mildew preventives, solubilizers, silicone with epoxy groups, fluorocarbon surfactants and deionized water. The anticorrosion water-based ultrathin fireproof paint for the steel structures has the advantages of excellent anticorrosion performance, good weather resistance, ageing resistance and adhesion, high steel bonding strength and long-acting fireproof, long-term weather-resistant, ageing-resistant and anticorrosion effects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a corrosion-resistant water-based ultra-thin fireproof coating for steel structures. Background technique [0002] Fireproof coating refers to a type of coating that is applied on the surface of objects to prevent fire, prevent the spread of fire or isolate the source of fire, prolong the ignition time of the substrate or increase the thermal insulation performance to delay the structural damage time, according to the purpose and the object of use. It can be divided into: decorative fireproof coatings, cable fireproof coatings, steel structure fireproof coatings, prestressed concrete floor fireproof coatings, etc. [0003] The development of China's fire-resistant coatings is 15-20 years later than that of foreign industrialized countries. Although it started late, it has developed rapidly, especially for steel structure fire-resistant coatings. International advanced level. I...

Problems solved by technology

With the development of society, people have put forward higher requirements for the performance of ultra-thin steel structure fireproof coatings. The formulations used in the existing ultra-thin steel structure fireproof coatings are not very reasonable. For example, the film-forming substances used are relatively simple; The synergistic effect of flame retardants is poor, and the obtained ultra-thin steel structure fire retardant coating has the defects of poor corrosion resistance and flame retardancy during use, so that the ultra-thin steel structure fire retardant coating loses its protective effect.
