Abstract

The invention discloses a preparation method of a high-performance water-based coating special for elevator guide rails. The preparation method comprises the following steps: S1, material preparation; S2, stirring: adding waterborne epoxy ester resin into a stirring kettle, performing stirring, adding a cosolvent, a drier and an amine neutralizer, performing stirring to dilute and neutralize the resin uniformly, adding deionized water, performing stirring to completely emulsify the resin, performing stirring again, and adding the wetting dispersant, the defoaming agent, the pigment, the filler and the anti-settling aid to obtain uniform pigment and filler slurry; S3, grinding; and S4, paint mixing: taking another stirring kettle, adding emulsion, performing stirring at a second rotating speed, adding the ground pigment and filler slurry, sequentially adding a defoaming agent, a base material wetting agent, an anti-flash-rust auxiliary agent and a thickening agent according to the formula, and performing filtering to obtain a coating product. The coating product is high in drying speed, adhesive force and hardness development speed, the film-forming resin is good in water resistance and salt spray resistance, and the product is good in tensile planing resistance by being matched with a proper amount of pigment filler and auxiliaries.

Description

technical field [0001] The invention relates to the technical field of industrial coatings, in particular to a method for preparing a high-performance water-based special coating for elevator guide rails. Background technique [0002] The general method to prepare water-based elevator guide rail protective paint, the coating effect on the surface of the workpiece with oil, rust, and dust is not ideal, and there are paint defects such as shrinkage cavities and volcanic pits on the surface of the paint film; the brushing has poor leveling, and there are problems such as brush marks and exposed bottom. The paint film of the workpiece is too thin and the exposed bottom area is corroded; the coating has poor anti-sag performance after being diluted with water, the façade paint is lost, and the ability to cover and protect the workpiece is lost. When the volume shrinks, the surface cracks; after the coating is completed, the paint film falls off when the elevator guide rail underg...
