Development of anti-corrosion coatings
1. The product develops towards multi-function
According to incomplete statistics, there are more than 1,000 varieties of anti-corrosion coatings in my country. The traditional classification of resins includes epoxy, epoxy asphalt, asphalt, chlorinated rubber, chlorosulfonated polyethylene, polyvinyl chloride, perchloroethylene, and urushiol resin. , Ethyl silicate, high chlorinated polyethylene, polyurethane, polyurethane asphalt, phenolic, alkyd paint, etc.
In recent years, many modified resin anticorrosive coatings with excellent performance have emerged, such as alkyd resin modified polysulfide rubber modified epoxy waterproof anticorrosive coating and acrylic modified alkyd enamel paint for railway passenger car boxes At the same time, it combines the anti-corrosion coatings with our own characteristics, such as urushiol titanium, urushiol epoxy, urushiol silicon heavy-duty anti-corrosion coatings, etc. Beginning in the 1990s, a new generation of anti-corrosion coating systems gradually occupied the mainstream of market research and application. Environmentally-friendly anti-corrosion coatings such as water-based epoxy and water-based acrylic coatings came out one after another, enriching the types of anti-corrosion coatings and gradually moving towards multi-functionality. development of.
2. Market demand and wide application range
There are many anti-corrosion coating companies in my country. According to incomplete statistics, there are about 700 companies. Among them, there are nearly 100 manufacturers specializing in anti-corrosion coatings, but they are all small in scale, and only a few dozen have an annual output of more than 1,000 tons. These production enterprises are mainly concentrated in my country's coastal provinces and cities and the central and southern regions. Due to the differences in the natural environment and development characteristics of various provinces and cities, the varieties and uses of anti-corrosion coatings are also different.
At present, my country's anti-corrosion coatings are mainly used in the chemical and petroleum industries, railways, highways and bridges, metallurgical industries, power and energy industries, machinery and textile industries, industrial products, automobiles, ships and container industries. Among them, the industries with the greatest demand are the chemical and petroleum industries, which include oilfield measures, oil pipelines, offshore platforms, and the corrosion protection of steel structures and reinforced concrete structures of petrochemical plants; at the same time, the construction and maintenance of railways and highway bridges are also The key areas of anti-corrosion coatings application, in addition, industrial product areas and marine anti-corrosion fields such as automobiles and ships are also the biggest demand points in the anti-corrosion coating market.
3, environmentally friendly anticorrosive coatings have attracted much attention
At present, my country's anti-corrosion coatings are advancing in the direction of high performance, high efficiency, low energy consumption and low pollution. There is also a department of water-based anti-corrosion coating manufacturers that use low-pollution raw materials for production. Anti-corrosion coating companies have eliminated the prohibited use This kind of coating material is replaced by more environmentally friendly raw material products to achieve the purpose of energy saving, emission reduction and environmental friendliness.
I believe that in the next few years, ship coatings, oil platforms, container coatings, chemical anti-corrosion coatings, railways, highways and bridges, steel structure anti-corrosion coatings, coatings for urban infrastructure measures are still hot in the market, and domestic anti-corrosion coating companies should continue to strengthen their professional standards. , Provide high-quality products and perfect services, so as to make greater efforts and contributions to China's anti-erosion market.
4. Marine anticorrosive coatings are growing rapidly
Nowadays, the scale of marine development continues to expand, and the sea-crossing bridge, which is the basic measure of marine development, will continue to be built. These marine structures need to have a longer anti-corrosion period, which will bring a huge market for marine anti-corrosion coatings. In addition, following the massive development of subsea oil fields, pipelines to transport oil and gas will emerge one after another. In recent years, the construction of basic measures for China's ports has been significantly accelerated, and the country is still actively planning and constructing marine power generation, which has brought new development opportunities for the marine anti-corrosion coating market. At present, my country's marine anti-corrosion coating production companies are moving towards the development of green, resource-saving, high-performance anti-corrosion coatings. In the future, we will also develop multi-functional anticorrosive coatings with high temperature corrosion resistance, antistatic, high elasticity, and non-toxicity. According to industry insiders, my country’s marine anti-corrosion coatings market will grow at an annual rate of more than 30%, driven by factors such as ship and container manufacturing, as well as the construction of cross-sea bridges, offshore oil platforms and coastal ports.
