Black water-based guide rail paint

The invention relates to black water-based guide rail paint. The paint comprises components in parts by weight as follows: 50 parts of organic silicon resin, 12 parts of a black pigment, 4 parts of filler, 1.5 parts of a carbon black dispersing agent, 25 parts of a solvent, 1.5 parts of an anti-settling agent and 6 parts of a curing agent. The prepared black water-based guide rail paint has gloss and keeps the gloss at the temperature higher than 300 DEG C and has the higher temperature resistance, the hardness of a paint film is higher than 0.5, and the hardness of the paint film is increased. Mica powder and talc powder are used as the high-temperature-resistant filler and have reinforcing effects on coatings of the black water-based guide rail paint, both the mica powder and the talc powder are silicate filler, and surfaces of the mica powder and the talc powder have a few hydroxyl groups which can have certain chemical reactions with functional groups of polysiloxane at the high temperature during grinding, so that mechanical properties such as abrasion resistance and the like of the black water-based guide rail paint are enhanced.
