Problems solved by technology

However, when the thermosetting powder coating is applied to the substrate coating, it is often necessary to carry out chemical pretreatment on the substrate; specifically, the iron substrate is a main substrate that requires protective decoration. When applying the existing thermosetting powder When coating, it is necessary to carry out complicated chemical pretreatment on iron substrates (mainly including silane pretreatment, zinc pretreatment and other chemical pretreatment processes), which will cause great pollution and energy consumption to the construction environment; if no chemical pretreatment , directly using thermosetting powder coatings for coating, which cannot meet the anti-corrosion requirements for substrate coating

Abstract

The invention discloses a corrosion-resistant powder coating composition, and the coating at least comprises the following raw materials: thermosetting resin, a curing agent for curing the thermosetting resin, carbon nanotubes and zinc powder. The invention further discloses a preparation method of the corrosion-resistant powder coating composition. The corrosion-resistant powder coating composition is obtained through mixing, melt extrusion and crushing. The invention also discloses a corrosion-resistant coating. The corrosion-resistant coating is prepared by spraying the corrosion-resistant powder coating composition on a base material and then carrying out curing molding. According to the invention, when the coating is directly carried out on the premise of not carrying out chemical pretreatment on the base material, the anti-corrosion requirement on the coating of the base material can be completely met, the coating process is obviously simplified, the coating efficiency is improved, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the field of powder coatings, and in particular relates to a corrosion-resistant powder coating composition. The invention also relates to a preparation method of the corrosion-resistant powder coating composition and a corrosion-resistant coating applied thereto. Background technique [0002] Thermosetting powder coatings are widely used to replace paints and water-based paints to achieve protective decoration on various material substrates due to their advantages of environmental protection, low energy consumption, convenient construction and no VOC emissions. However, when the thermosetting powder coating is applied to the substrate coating, it is often necessary to carry out chemical pretreatment on the substrate; specifically, the iron substrate is a main substrate that requires protective decoration. When applying the existing thermosetting powder When coating, it is necessary to carry out complicated chemical pretreatmen...
