Problems solved by technology

Generally, hot spray galvanizing or galvanizing is used for brushing, and some of them are painted with anti-corrosion paint. The existing problems are: high requirements for anti-corrosion substrate treatment, too thick coating film is easy to crack, and the paint film is greatly affected by temperature and humidity when it is cured. , 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
In addition, it is also necessary to pickle and wash the steel substrate, and to treat and discharge waste water and waste acid, which is not conducive to environmental protection, and consumes a lot of energy and uses high costs.

Abstract

The present invention discloses a cold zinc-spraying coating material, which comprises, by mass, 5-10 parts of a modified resin, 93-98 parts of high-purity zinc powder, 1-3 parts of nanometer siliconcarbide, 0.5-1.0 part of an anti-settling agent, and 5-10 parts of an organic solvent. The invention further discloses a preparation method of the cold zinc-spraying coating material. According to thepresent invention, the obtained cold zinc-spraying coating material has characteristics of strong adhesion, low influence by external temperature and humidity, and good weather resistance, and does not require acid washing and water washing for steel and iron substrates so as to greatly reduce energy consumption and greatly reduce the treatment and discharge of wastewater and waste acids, such that the environmental protection is easily achieved, and the cold zinc-spraying coating material is the ideal product for replacing the hot-dip galvanizing process.

Description

technical field [0001] The invention belongs to the field of anticorrosion coatings, and in particular relates to a cold-coated zinc coating and a preparation method thereof. Background technique [0002] Since the steel structure is often corroded by external factors such as the atmosphere and chemical substances, corrosion usually occurs after several years of operation, which seriously affects the life of iron materials. In order to prolong the service life of the equipment and ensure the safe operation of the equipment, it is necessary to take timely anti-corrosion measures for iron materials, and propose high-efficiency and durable anti-corrosion coatings, and even require semi-permanent protection to prolong the service life of the equipment. [0003] At present, more than half of the steel products in the world are protected against corrosion by zinc protection. Zinc remains the simplest and most effective corrosion protection material. Generally, hot spray galvaniz...
