With the development of China's national economy, the country continues to increase investment in infrastructure construction and speed up its construction. In this process, infrastructure construction has also driven the development of a series of industries and promoted the continuous progress and upgrading of various technologies. With the development trend of infrastructure design from reinforced concrete to steel structure, coatings are facing new requirements, especially in the aspects of corrosion protection life of coatings, coating performance of materials, seasonal versatility of materials and environmental friendliness.

 

 

 

According to the data of China corrosion survey report, the annual loss caused only by the corrosion of metal materials in China is up to 500 billion yuan, accounting for 5% of the GDP! Among them, the oil and gas system is about 10 billion yuan, the coal industry is about 5.5 billion yuan, and the power system is about 1.6 billion yuan. However, the total industrial output value of the whole coating industry (less raw materials) is only half of it, so it can be seen that the anticorrosive coating can be used as a large space.

 

 

 

Today's anticorrosive coating products are widely used as raw materials in petroleum industry, coking industry, organic synthetic chemical industry and other sectors, with more and more quality and expanding application range. How to further accelerate the development of anticorrosive coating field and make it better serve all walks of life is a glorious and arduous task in front of our coating people.

 

 

 

In the broad market environment of anticorrosive coatings, only if the coating people bravely take technological innovation as the driving force, take environmental protection as their own duty, and constantly develop new technologies and products, can the application scope of anticorrosive coatings be continuously expanded, and contribute their own strength to China's infrastructure and marine chemical industry.

 

 

 

Development status

 

 

 

Anticorrosive coating is widely used in modern industry, transportation, energy, marine engineering and other departments. According to the corrosion resistance and application requirements of the coatings, they are generally divided into conventional type and heavy-duty type.

 

 

 

Conventional anti-corrosion coating is a kind of anti-corrosion coating that can protect the service life of non-ferrous metals under general conditions and plays an anti-corrosion role on metals; heavy anti-corrosion coating is a kind of anti-corrosion coating that can be applied in relatively harsh corrosion environment and has a longer protection period than conventional anti-corrosion coating.

 

 

 

1. Product development towards multi-function

 

 

 

According to incomplete statistics, there are more than 1000 kinds of anti-corrosion coatings in China. The traditional classification by resin includes epoxy, epoxy asphalt, asphalt, chlorinated rubber, chlorosulfonated polyethylene, PVC, perchloroethylene, urushiol resin, ethyl silicate, high chlorinated polyethylene, polyurethane, polyurethane asphalt, phenolic, alkyd paint, etc.

 

In recent years, there are many kinds of modified resin anticorrosive coatings with excellent performance, such as alkyd resin modified polysulfide rubber modified epoxy waterproof anticorrosive coating and acrylic acid modified alkyd enamel used for railway passenger car box, etc. at the same time, combined with our own characteristics of anticorrosive coatings, such as URUSHIOL TITANIUM, urushiol epoxy, urushiol silicon heavy anticorrosive coating, etc. Since the 1990s, a new generation of anti-corrosion coating system has gradually occupied the mainstream of market research and application. Environmental friendly anti-corrosion coatings such as water-based epoxy, water-based acrylic paint, etc. have come out one after another, enriching the types of anti-corrosion coatings, and gradually developing towards the direction of multi-function.

 

2. Broad market demand and application scope

 

There are many anti-corrosion coating manufacturers in China. According to incomplete statistics, there are about 700, among which nearly 100 are specialized in producing anti-corrosion coating, but the scale is not large, and the annual output is only dozens. These enterprises are mainly concentrated in the coastal provinces and cities and the central and southern regions of China. Due to the differences of natural environment and development characteristics in various provinces and cities, the varieties and uses of anti-corrosion coatings are also different.

 

At present, China's anti-corrosion coatings are mainly used in the chemical and petroleum industry, railway, highway and bridge, metallurgical industry, power and energy industry, machinery and textile industry, industrial product field, automobile, ship and container industry. Among them, the industry with the largest demand is chemical industry and petroleum industry, which includes anticorrosion of steel structure and reinforced concrete structure of oilfield facilities, oil pipelines, offshore platforms and petrochemical plants; meanwhile, the construction and maintenance of railway and highway bridges are also the key areas of anticorrosive coating application, in addition, the industrial products field, automobile, ship and other marine anticorrosion fields are also anticorrosive. The biggest demand point of paint market.

 

3. Environmental protection anti-corrosion coating attracts much attention

 

At present, China's anticorrosive coatings are moving forward in the direction of high performance, high efficiency, low energy consumption and low pollution, and some water-based anticorrosive coating manufacturers have adopted low pollution raw materials for production. Anticorrosive coating enterprises have eliminated all kinds of prohibited coating raw materials and replaced them with more environmentally friendly raw materials to achieve energy conservation, emission reduction and environmental friendliness.
