Abstract

The invention provides an anti-skid powder coating. The anti-skid powder coating is prepared from carboxyl-terminated polyester resin, a curing agent, filler, talcum powder, titanium dioxide, mica powder, an anti-skid additive, a wear-resistant additive, a curing accelerator, a three-dimensional sand streak agent, a conventional additive, a surface roughening agent, a dispersing agent and pigment. Through cross-linking reaction of two carboxyl-terminated polyester resins with different acid values and the curing agent, the weather resistance of the prepared anti-skid powder coating is improved, and the cross-linking reaction of the two carboxyl-terminated polyester resins with different acid values and the curing agent can be effectively accelerated by adding the curing accelerator, so that the coating is quickly cured, and the anti-skid performance of a coating film is improved; and the mica powder, the dispersing agent and the anti-skid additive are premixed and then added, and the mica powder, the dispersing agent, the anti-skid additive, the three-dimensional sand streak agent, the surface roughening agent and the wear-resistant additive have a synergistic effect, so that a concave-convex state is formed on the surface of a coating, a three-dimensional effect is achieved, and the anti-skid powder coating has remarkable anti-skid performance, wear resistance, weather resistance and scratch resistance.

Description

technical field [0001] The invention relates to the field of powder coating preparation, in particular to an anti-slip powder coating and a preparation method thereof. Background technique [0002] Coating is a general term for a class of liquid or solid materials that can form a solid coating film with protective, decorative or special properties (such as insulation, anti-corrosion, marking, etc.) on the surface of an object, including oil-based paint, water-based paint, and powder coating. The function of the anti-slip coating is to change the roughness of the coating surface, increase the friction on the surface of the coating film, and form a non-slip surface with a high friction coefficient to reduce casualties and property losses. However, most of the anti-slip coatings in the prior art are prepared by using paint as a binder (film-forming substance) and anti-slip aggregates with a particle size less than 50 meshes, but this type of anti-slip coating has the problem of...
