Towards water-based marine coatings

China's paint from nothing, and gradually developed into an important industry in the national economic life exudes vitality, especially since 2009 China has been six consecutive years "paint production and sales of the world's first" throne, in the world paint industry occupies a place.
high-speed development history is surprising, but the times change, China's paint transformation has become the primary proposition."13th Five-Year Plan" formally proposed to reduce the total amount of VOC emissions by 10%, "target" proposed to reduce emissions by 3.3 million tons over three years, regional emission reduction plans have been issued .
At present, China continues to introduce emission standards, levy VOC sewage charges and give treatment subsidies, some urban sewage charges have been higher than or close to the cost of pollution control, in addition to VOC prevention and control countries are strongly supporting the development of aerospace, ship docks, high-end cars, bridge steel structure, marine, wind power generation and other industries in urgent need of high-grade special coatings, improve product quality, replace imports.ships sail in the ocean, and the parts of the hull that come into contact with seawater are subject not only to strong electrochemical corrosion of seawater, but also to the defaces attached to marine life.
seawater and microorganisms reduces the life of the ship, increases the cost of maintenance and repair, and, more seriously, threatens the safety of the ship's navigation. At present, the most effective anti-corrosion and anti-fouling method is through water-based coatings to protect the hull metal, to prevent its corrosion.compounds (VOCs) produced by conventional solvent-based coatings are mostly toxic.
with the enhancement of the whole society's awareness of environmental protection and labor protection, countries around the world have formulated laws and regulations to limit VOC emissions.
To water-based acrylic coatings, for example, it is prepared with water, additives and acrylic / methyl acrylic / acrylates, acrylic polymer dispersed in water and crosslinking agents, crosslinking agents in curing can cross-link with acrylic polymers, forming a mesh structure of the polymer coating film, and thus play a corrosion-resistant effect.The current modified study of acrylic resin has replaced the study of a single acrylic system,
such as epoxy resin modified acrylic resin makes it both advantages, such coatings in high temperature resistance, acidity and alkalinity and environmental protection, etc. have a greater advantage, has been successfully applied to marine platforms, containers, bridges, chemical plants and television towers and other facilities
.with the 13th Five-Year Plan emission reduction pressure more and more huge, in the long run is the fundamental way to achieve VOC emission reduction.
paint alone, the country consumes 15 million tons of paint per year, VOC emissions reached more than 6 million tons.
when solvent-based coatings under environmental pressure scenery no longer, a water-based coating era has quietly come.
