Water-based Anticorrosive Paint Boosts The Environmental Protection Trend Of Transportation Equipment

Jun 03, 2020

The most common water-based anticorrosive paints and coatings are three major systems: acrylic system, epoxy system, inorganic silicic acid zinc-rich system. In addition, there are alkyd system, styrene butadiene rubber system and asphalt system. Waterborne acrylic anticorrosive coatings are based on solid acrylic resins, modified resins, pigments, fillers, additives, solvents, etc. to make acrylic long-lasting waterborne anticorrosive coatings with weather resistance, gloss retention, color retention and other properties. The most recent research is water-based iron red acrylic anti-rust paint. Now water-based epoxy anticorrosive coatings have been applied to various fields involved in solvent-based epoxy anticorrosive coatings.

  Since the majority of the logistics transportation equipment is outdoors, its protection, safety and aesthetics need to be improved by coating. The quality of coating and coating quality are important indicators for logistics transportation equipment. With the increasing needs of the industry market and the awareness of environmental protection and the successive introduction of environmental-related industry regulations, logistics companies not only have higher and higher quality requirements for the coating of transportation equipment, but also invest in the safety, health and environmental protection of equipment production In order to pay more attention, the coatings of logistics transportation equipment have shown a trend towards water-based, high-curing and solvent-free.

  Water-based inorganic silicate zinc-rich anticorrosive coatings are mainly divided into ethyl silicate and silicate series. The silicate series include lithium silicate, sodium silicate, potassium silicate and other varieties, which are an important part of steel anticorrosive coatings. The coating utilizes the strong activity of zinc powder for electrochemical cathodic protection, thereby preventing steel corrosion. Inorganic polymers (silicates, phosphates, dichromates, etc.) are used as film-forming substances, and zinc reacts with them to form a zinc-iron complex coating on the steel surface. The coating has excellent corrosion resistance, weather resistance, thermal conductivity, salt water resistance, resistance to a variety of organic solvents; at the same time has good static conductivity and long-term cathodic protection; and excellent welding performance, can be welded with paint; Long-term resistance to 400℃ high temperature; long-term resistance to chemical corrosion in the range of 5.5~10.5pH. More importantly, it has no pollution to the environment and no impact on human health.
