[China Aluminum Industry Net] Environmental protection waterborne coatings have low VOC content and have little harm to the environment and human body. With the continuous improvement of environmental protection awareness and the improvement of environmental protection regulations, waterborne coatings have made considerable progress. In foreign countries, waterborne coatings have entered some high-end industries such as rail transit vehicles.
Domestic water lacquer is also developing relatively quickly, such as the use of water lacquer in auto parts, steel structures, engines, and agricultural machinery. In recent years, China's construction machinery products have also been rapidly developed. Due to the large size of most construction machinery products, the demand for paints is large. The average amount of paint used for an excavator has reached 50KG, and the market prospects for construction machinery coatings Very broad, in order to improve the competitiveness of products, construction machinery manufacturers are no longer limited to the internal quality and performance of the product, and obtain coatings with good corrosion resistance and good appearance quality. At the same time, construction machinery painting is singing energy saving, environment-friendly and low-carbon. Coating technology should be trending, such as waterborne coatings, high solids coatings, and powder coatings. However, due to the complexity of structural parts of construction machinery, powder coatings cannot be applied at present. Therefore, high solids and waterborne coatings are preferred.
There are still toxic solvents in high-solids coatings. Therefore, the waterborne coating of construction machinery is of great significance to the entire coating industry. The water-based paint spraying process has been applied in the coating production of automotive parts. The accumulation of these technologies provides technical guidance for the application of water paint in construction machinery.
Of course, waterborne coatings also have their own weaknesses, such as: strict requirements on the pre-treatment of the workpiece surface; strict humidity control during the drying process; and the use of stainless steel equipment.
Waterborne industrial paint primers and topcoat performance requirements:
Primer: Primer commonly used in construction machinery. According to the classification of resins, there are mainly alkyd primers, epoxy primers, polyurethane primers, and acrylic primers. Among them, the two-component epoxy primer has better overall performance and is currently Apply a wider range of coatings.
Topcoat: Polyurethane resin topcoat is a topcoat used in construction machinery industry in recent years. The paint film has high hardness, high gloss, fullness, abrasion resistance and excellent overall performance. Waterborne two-component polyurethane topcoats have outstanding resistance to aging and corrosion.
