[0030] The present invention provides a paint for a slider, and the preparation raw materials include a paint base, a curing agent, and a thinner;

[0031] The paint base includes:

[0032] 30 to 50 parts by mass of a saturated polyester resin;

[0033] 1 to 15 parts by mass of a polyurethane micro-powder;

[0034] 0.5 to 3 parts by mass of an organosilicon resin micro-powder;

[0035] 5 to 10 parts by mass of a matting powder;

[0036] 20 to 60 parts by mass of a solvent;

[0037] 0.3 to 3 parts by mass of an auxiliary agent;

[0038] In the paint base, the hydroxyl value of the saturated polyester resin is 140 to 170;

[0039] The paint is sprayed on the slider to form concave and convex textures.

[0040] The preparation raw materials of the paint provided by the present invention include a paint base. Among them, the paint base includes 30 to 50 parts by mass of a saturated polyester resin, which can be 30, 35, 40, 45, 50, or any value between 30 and 50 parts by mass. Among them, the hydroxyl value of the saturated polyester resin is 140 - 170. Within this hydroxyl value range, the hydroxyl value reflects a high crosslinking density. Appropriately increasing the hydroxyl value of the saturated polyester resin can make the paint layer have better weather resistance, yellowing resistance, and washing fastness.

[0041] The paint base further includes 1 to 15 parts by mass of a polyurethane micro-powder, which can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or any value between 1 and 15 parts by mass. In the present invention, the particle size range of the polyurethane micro-powder is 15 - 35um. Within this particle size range, the qualified rate of the finished slider can be ensured, and the adhesion of the paint layer can be increased.

When the particle size is lower than 20 μm, the cloth texture effect cannot be formed on the paint layer; when the particle size exceeds 50 μm, the pull head and the cap are prone to sticking and scratching each other.

[0043] The paint base material further includes 5 to 10 parts by mass of matting powder, which can be 5, 6, 7, 8, 9, 10, or any value between 5 and 10 parts by mass. In the present invention, the matting powder is selected from Degussa OK520 matting powder.
