Embodiment 1

[0027] The epoxy coating of the present embodiment is made of iron red epoxy ester primer and Y 2 o 3 Composition, Y 2 o 3 The quality of iron red epoxy ester primer is 0.05% of the quality of iron red epoxy ester primer; the mass percentage of iron red epoxy ester primer consists of: iron red 22%, zinc yellow 12%, talcum powder 8.00%, ZnO7.00%, 10% Pb lead naphthenate 0.70%, 3% Co cobalt naphthenate 0.60%, 3% Mn manganese naphthenate 0.90%, 7:3 xylene / butanol 5%, the balance is 50% solid epoxy ester resin . Among them, 10% Pb lead naphthenate is a lead naphthenate solution with a mass concentration of 10%, and 3% Co cobalt naphthenate and 3% Mn manganese naphthenate have similar meanings.

[0028] The preparation method of the epoxy paint of the present embodiment comprises: Y 2 o 3 The powder is ground to a particle size of no more than 15 μm, then mixed evenly with the one-component iron red epoxy primer, and left to stand for 20-30 minutes to obtain the product.

Abstract

The invention discloses an epoxy coating as well as a preparation method and an application method thereof. The epoxy coating is prepared from iron oxide red epoxy ester undercoat and Y2O3, wherein the mass of Y2O3 is 0.05%-0.25% that of the iron oxide red epoxy ester undercoat. According to the provided epoxy coating, Y2O3 can increase the reaction activity of the epoxy coating, the epoxy coating can have a function of a catalyst, and the binding force of a coating film and a base body is improved. The epoxy coating has good binding force with different base bodies after hot galvanizing sand papering, rusted hot-dip galvanized steel brush treatment, steel material power treatment, rusted steel sand papering, aluminum alloying treatment, sand blasting of steel, phosphating treatment of the steel, treatment of old acrylate polyurethane coatings through manual or power tools, treatment of old epoxy coatings through manual or power tools, treatment of old fluorocarbon coatings through manual or power tools and the like, has very high adaptability and can be conveniently used for outdoor coating maintenance construction of power transmission and transformation equipment.

Description

technical field [0001] The invention belongs to the field of epoxy coatings, and in particular relates to an epoxy coating, a preparation method thereof, and a coating method. Background technique [0002] After the power transmission and transformation equipment is put into operation, due to the relatively harsh service environment, the paint film on the surface of the substrate is damaged quickly, and generally needs to be repainted and maintained after 2 to 3 years; and the equipment that needs to be maintained is often scattered. When maintaining and repairing the equipment on the mountain, it is often difficult to meet the pre-treatment requirements of the general anti-corrosion primer. GB / T 8923-2011 "Steel Surface Treatment Before Coating" stipulates the derusting level of steel before painting. Rust removal effect, easy to ensure the protective effect of the coating; when the power transmission and transformation equipment is repaired with old coatings, it is often ...
