Waterborne anti-corrosion and fireproof integrated paint

Abstract

The invention provides waterborne anti-corrosion and fireproof integrated paint and relates to building paint. The waterborne anti-corrosion and fireproof integrated paint comprises, by weight, 20-25 parts of waterborne epoxy resin emulsion, 25-30 parts of waterborne acrylic resin emulsion, 5-10 parts of flame-retardant filler, 3-5 parts of anti-corrosion filler, 10-13 parts of curing agent, 0.5-2 parts of dispersing agent, 0.5-0.8 part of defoaming agent and 10-15 parts of water. The waterborne epoxy resin emulsion and the waterborne acrylic resin emulsion serve as base body emulsion, so the paint has good corrosion resistance and high adhesion performance of the waterborne epoxy resin emulsion and also has good acid resistance, alkali resistance and ultraviolet resistance of the waterborne acrylic resin emulsion. The flame-retardant filler is free of toxin and harm, water serves as a solvent of the paint, the paint is nonflammable, easy to store and environmentally friendly, and the paint has dual effects of corrosion resistance and fireproofing.

Description

technical field [0001] The invention relates to a building coating, in particular to a water-based anticorrosion and fireproofing integrated coating. Background technique [0002] With the development of my country's national economy, the continuous increase of steel output and the continuous improvement of steel structure construction technology, steel structure buildings will become a new economic growth point of construction. However, the wide application of steel structures also exposes a series of shortcomings, and the more serious ones are fire hazards and corrosion of steel structures. Therefore, fire protection and anti-corrosion treatment must be carried out for steel structures. [0003] At present, most steel structures deal with the problem of anticorrosion and fire prevention by first brushing a layer of anticorrosion primer on the surface of the steel, and then painting the surface with a fireproof coating after the anticorrosion primer is fully cured, so as to...

Problems solved by technology

Although this method has a certain fireproof effect, it also has many disadvantages: two layers of paint need to be brushed twice, resulting in complicated construction; two layers of coating need to consider the compatibility between the two coating interfaces, if they are compatible If the performance is not good, it will directly cause the external coating to fall off easily, which will affect the life of the coating.

In recent years, some anti-corrosion and fire-proof coatings have also appeared, but it is difficult to balance the performance of both anti-corrosion and fire protection, which will cause some unilateral defects in the coating, and most of the current anti-corrosion and fire-proof coatings are solvent-based , pollute the environment
