preparation example Construction

[0051] C, the preparation of curing agent is that raw material (15)-(16) is placed in the container by above-mentioned ratio and stirs and mixes, and stirs evenly, output curing agent product, packs with iron drum, stand-by;

[0052] D. The preparation of the flame-retardant topcoat is to mix the finished paint base and the curing agent in a weight ratio of 1:0.3-0.5 during use, which is the flame-retardant topcoat of the present invention.

[0053] The flame-retardant topcoat for subway vehicles prepared by the method of the invention.

example 1

[0056] The production of color paste, with 39.5 parts of acrylic resin (produced by Bayer, Germany, solid content 70%, available domestically), as pigment titanium dioxide (produced by U.S. Dupont (Taiwan) Company, available in the territory, TiO 2 Minimum 93%, Al 2 o 3 Typical 2.5%, SiO 2 3.0%, specific gravity 4.0, average particle size 0.26μm) 24.5 parts, dispersant (polymer block copolymer solution containing pigment affinity groups, produced by BYK company in Germany, available in China) 0.3 parts, as anti-settling agent gas phase SiO 2 , (produced by German degussa company, available in China, specific surface area 110±20m 2 / g) 0.2 part, foam-breaking polymer and polysiloxane (produced by BYK company in Germany as defoamer, domestically available, solid content 40%) 0.2 part, xylene+butyl acetate as diluent + 3.3 parts of a mixture composed of propylene glycol methyl ether acetate (prepared by weight ratio 1:1:1, xylene, butyl acetate, and propylene glycol methyl et...

Abstract

The invention discloses a subway vehicle inflaming retarding finish paint and aims at providing an environmental-friendly inflaming retarding finish paint with efficient inflaming retarding, low toxicity and low smoke, which is prepared by the steps of soaking, grinding, toning, filtering and the like after mixing raw materials not containing halogen family elements, such as acrylic resin, titanium, dispersant, anti-settling agent, antifoaming agent, thinning agent, flatting agent, drier, ultraviolet absorber, hindered-amine, organic phosphate and isocyanates of aliphatic hydrocarbon. The invention is mainly used as the inflaming retarding finish paint of subway vehicles.

Description

technical field [0001] The invention relates to a flame-retardant topcoat and a preparation method thereof, in particular to a flame-retardant topcoat for subway vehicles and a preparation method thereof. Background technique [0002] At present, the research and production of flame-retardant coatings in China are developing rapidly and there are many varieties. It can be roughly divided into two categories: one is architectural coatings with inorganic salts, oxides, and mineral powders as flame retardants. This type of coating has good flame retardant performance and low cost, and the coating is generally thick. It is decorative and beautiful as a topcoat Insufficient performance, not suitable for subway vehicle topcoat. The other is to use organic halogen compounds as flame retardants. This kind of flame retardants emits a large amount of corrosive gas when burned, which is highly toxic and has a high smoke content, which is easy to suffocate people. This also does not a...
