The 13th Five-Year Plan of the paint industry clearly sets out the VOC emission reduction plan for coatings in industrial fields such as automobile, shipbuilding, steel structure, container, construction machinery and color steel, etc. We need to vigorously promote the coating of low-VOC paint. Among them, The development and application of water-borne industrial coatings is one of the key points, which guarantees that the target of achieving 60% or above of low-VOC green paint as stipulated in the Action Plan for Volatile Organic Compounds Reduction in Key Industries will be achieved by the end of 2018.
In fact, in recent years, with the continuous improvement of environmental protection laws and regulations of our country and the enhancement of consumers' environmental protection awareness, the paint market tends to be more healthy and safer, and the overall reform of oil and water is intensifying .2011-2016, China's waterborne coatings market The scale has increased from 35.3 billion yuan to 54 billion yuan, with an average annual compound growth rate of 9%. Some agencies predict that the next 5 years, water-based coatings will grow at an average rate of 23%; to 2022 China's water-based paint production will be Reaching 6.34 million tons.
'Oil to water' process accelerated
Few people know that paint is also one of the factors that can cause smog, because many solvents in oily paints are extracted from petroleum, which contains large amounts of volatile organic compounds (VOCs) Pollute the air, endanger human health.As water-based paint as a solvent, water-based paint can effectively reduce the VOC emissions and reduce environmental pollution.Industry sources said that water-based paint VOC emissions lower than the oil-based paint 60% -70%, environmental benefits are obvious.
In recent years, with the continuous promulgation of various environmental protection policies, the coatings chemical industry has carried out a strong policy control, environmental coatings such as water-based paint usher in rapid development opportunities, 'oil to water' process and gradually accelerate.
At present, the architectural coatings, water-based coatings has basically completed the transformation of the current 95% of the interior and exterior coatings are water-based paint.
In the field of industry, water-based paint is also more and more favored by users.A relevant official said that the company currently all truck production has been the use of water-based paint, locomotive maintenance is also the basic use of water-based paint, including the shaft brushing are all used Water-based paint. "This is policy-oriented support on the one hand, on the other hand is also responsible for the enterprise itself. The use of water-based paint also allows the health of the coating industry staff well protected.
Recently, China's container industry also made clear that the whole industry has unified the technical route of promoting and applying water-borne coatings, and has formulated the product standards of container water-borne coatings. As a result, Process specifications, quality testing standards, as well as accounting standards for VOCs emissions, using standardized means to promote the development of waterborne coatings industry container.
Paint company chief engineer believes that the development of China's water-based industrial coatings in the technology has matured, the same quality use of water-based industrial paint will not increase customer costs; water-based industrial paint quality can reach or exceed solvent-based products, customers choose water-based industrial paint , No need to transform the painting site, the same applies to northern cold areas.
Promote the industrial application of the key
Although waterborne coatings have gained increasing popularity in the industrial arena, their proportion is still much lower than in the area of architectural decoration, for example, in the field of industrial protection, waterborne coatings make up only one third of the total. In the field of rail transportation, The proportion of water-based paint coating is lower.
A paint company engineer said that the developed countries in Europe have been implementing waterborne paint rail coating; domestic car industry, railway locomotive truck also achieved water-based paint spraying.For the rail passenger car, only a small amount of city subway to achieve the bulk of the vehicle water Coating, the EMU has not yet achieved operational assessment, bulk water-based applications.He believes that at present, for the rail vehicle coating, the implementation of standards of water-based paint ambiguous, there is no system standard, restricting the water-based paint Of the volume of use.In addition, water-based paint exhaust gas treatment and wastewater treatment issues also restrict the development of water-based coatings.
In recent years, with the rapid development of environmental protection, containers are required to be environmentally friendly, non-toxic and container-packed. Central European train and export cars are even more important. Therefore, accelerating the promotion of water-based coatings has become an inevitable trend in the development of the industry. A deputy chief engineer said.
'Ecological environment is all mankind, in the 21st century, we should do something meaningful and meaningful.Coatings account for 20% of air pollution, of which industrial coatings accounted for 2/3, so to solve industrial coatings pollution is the most important work The weight of environmental responsibility. 'Industry insider said.
In respect of environmental protection, a win-win future, the upstream and downstream waterborne industrial coatings companies to work together for the end-user service, create a new industrial coating development model. To protect the ecological environment to develop, manufacture and use of coating The Company will set up an efficient and interactive sharing platform for coating standards, products, technologies, information and services of water-borne industrial coatings to speed up the transformation of the surface protection and decoration of industrial products to realize the application technology system of waterborne industrial coatings with safety, environmental protection and reliability, Constantly establish and improve the branch of the various mechanisms conducive to green manufacturing and healthy development of the mechanism and system to promote environmentally friendly coating integrated project management.
