Problems solved by technology

[0002] The anti-corrosion of existing power transmission and transformation lines and equipment is generally painted by hot-spray galvanizing or galvanizing, and some are painted with anti-corrosion paint. When the paint film is cured, it is greatly affected by temperature and humidity, and the curing time is long, and most of them have the disadvantages of poor weather resistance and weak adhesion, so the anti-corrosion performance is generally not ideal

Embodiment Construction

[0007] Below in conjunction with embodiment the present invention is described in further detail.

[0008] Cold-applied zinc anti-corrosion coatings are composed of two parts: primer and surface sealing material. The primer contains two components, A and B. The component A is composed of E- 44 Epoxy and S 01-2 Polyurethane paint is made by mixing 7:3 by weight. Component B is made by mixing cured zinc paste (zinc oxide) and dibutyl fat by weight ratio 5:1. The weight ratio of A and B is 12.5: 1 mix. The surface mount material contains two components C and D, and the C component consists of E- 44 Epoxy and S 01-2 The polyurethane paint is made by mixing 6:4 by weight, the D component is dibutyl fat, and the C and B components are mixed by 6:1 by weight.

[0009] The mature zinc paste in the primer is zinc oxide, which is one of the important components of anti-corrosion coatings. Zinc oxide is used as a film-forming material to directly protect the corrosion substrate and e...

Abstract

The invention relates to a cold zinc coating anticorrosive paint, in particular to the cold zinc coating anticorrosive paint for transmission and transformation lines and devices. The paint consists of a backing material and a surface sealing material. The backing material contains epoxy resin, a polyurethane paint, cured zinc slurry and bioctyl ester. The surface sealing material contains epoxy resin, the polyurethane paint and bioctyl ester. According to the paint, zinc is used as a film forming material to protect lines and devices, a corrosion product (zinc hydroxide) of zinc is filled in a pinhole of the coating, and the epoxy resin is used as a high molecular bond, so that the affinity to the surface of a corrosive matrix is enhanced. The surface coating is sealed, so that the anticorrosive performance of the paint is improved. The cold zinc coating anticorrosive paint provided by the invention has the characteristics of strong bonding force, good anticorrosive performance, and convenience in construction.

Description

technical field [0001] The invention relates to a cold-coated zinc anti-corrosion coating, in particular to a cold-coated zinc anti-corrosion coating used on power transmission lines and equipment, and belongs to the technical field of anti-corrosion coatings. Background technique [0002] The anti-corrosion of existing power transmission and transformation lines and equipment is generally painted by hot-spray galvanizing or galvanizing, and some are painted with anti-corrosion paint. When the paint film is cured, it is greatly affected by temperature and humidity, and the curing time is long, and most of them have the disadvantages of poor weather resistance and weak adhesion, so the anti-corrosion performance is generally not ideal. Contents of the invention [0003] The purpose of the invention is to disclose a cold-coated zinc anticorrosion paint with good anticorrosion performance and convenient construction. [0004] In order to achieve the above purpose, the techni...
