Fireproof polyurethane floor coating

Abstract

The invention discloses fireproof polyurethane floor coating. The floor coating comprises the following components in parts by weight: 78 to 86 parts of waterborne polyurethane resin, 20 to 24 parts of melamine formaldehyde resin, 15 to 25 parts of polyvinyl acetate emulsion, 16 to 18 parts of paraffin emulsion, 3 to 7 parts of alkylbenzene sulfonate, 6 to 8 parts of vinyl trimethoxysilane, 11 to 14 parts of hydroxyethyl cellulose, 3 to 7 parts of dinonylnaphthalene sulfonic acid, 1 to 4 parts of butyl titanate, 4 to 7 parts of citric acid, 3 to 7 parts of zinc naphthenate, 2 to 4 parts of sodium borate, 5 to 12 parts of a polyurethane curing agent and 10 to 15 parts of a polyurethane dispersant. The fireproof polyurethane floor coating disclosed by the invention is free of solvents, non-toxic and harmless, and environment-friendly to avoid harm of the organic solvents on health of a human body, and can realize completely environment-friendly construction and application. Furthermore, the fireproof polyurethane floor coating has the characteristics of better water resistance and fire resistance, high tinting strength and yellowing resistance, and further is higher in layer surface brightness, brighter in color and luster and more excellent in physical properties.

Description

technical field [0001] The invention relates to a floor paint, in particular to a polyurethane fireproof floor paint. Background technique [0002] Floor paint was first invented by Germany in 1934. It is mainly made of oil, tree materials, colors, solvents, etc. It is mainly divided into decorative floor paint, heavy-duty anti-corrosion floor paint, and heavy-duty floor paint. Floor paint is made up of many different substances through many production processes such as mixing, dissolving, and dispersing. Floor paint has the characteristics of bright, real, beautiful, wear-resistant, waterproof, and anti-corrosion. Floor paint is made up of many different substances through many production processes such as mixing, dissolving, and dispersing. According to the different functions of each component of floor paint, it can generally be divided into main film-forming substances, secondary film-forming substances and auxiliary film-forming substances. Since the middle and late ...

Problems solved by technology

At present, floor paint is divided into solvent-based and solvent-free. Solvent-based floor paint has high requirements for substrate humidity and environmental humidity during construction; solvent-free water-based floor does not have much requirements for substrate and environmental humidity. Because of its non-flammable and non-explosive nature, it is safer and more environmentally friendly in production, transportation, storage, construction, etc. However, compared with solvent-based floor coatings, water-based floor coatings have disadvantages such as low paint film density and poor construction, and their market share is relatively small.
