Problems solved by technology

Alkyd paint and acrylic paint are one-component paints, which are easy to use, but have poor protection performance, and the general service life is about three years
Epoxy coatings and polyurethane coatings have good protective properties, but they are two-component coatings, which need to be mixed and stirred in proportion before they can be used, and have a pot life requirement, and coatings beyond the pot life cannot be used , easy to cause waste; in addition, the existing light pole coating will produce chemical wastewater during the production process, which will pollute the working environment and affect the health of workers

Abstract

The invention provides a high weather-resistant galvanized coating for a lamp post and a preparation method thereof, and relates to the technical field of coatings. The high weather-resistant galvanized coating for the lamp post is prepared from the following raw materials in parts by weight: acrylic resin, attapulgite, diatomite, light calcium carbonate, toughening agents, defoamers, driers, leveling agents, stearic acid, hindered amine antioxidants, anti-skinning agents, coupling agents, zinc powder and deionized water. The preparation method comprises the following steps: (1) weighing the raw materials; (2) preparing modified zinc powder; (3) mixing; (4) stirring and filtering the materials. The high weather-resistant galvanized coating for the lamp post prepared by the invention has the advantages of good protection and high weather resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a highly weather-resistant galvanized coating for light poles and a preparation method thereof. Background technique [0002] Most light poles are made of steel, which is prone to local damage during transportation and installation, and the damaged part will become a source of corrosion. In addition, light poles are also very easy to corrode under acid rain conditions. For corroded light poles, conventional alkyd paint, epoxy paint, polyurethane paint, etc. are usually used for repair. Alkyd coatings and acrylic coatings are one-component coatings, which are easy to use, but have poor protection performance, and the general service life is about three years. Epoxy coatings and polyurethane coatings have good protective properties, but they are two-component coatings, which need to be mixed and stirred in proportion before they can be used, and have a pot life requi...
