With the development of modern industry, the concentration of gases such as carbon dioxide and hydrocarbons in the atmosphere continues to increase, leading to rising global temperatures and polluting the environment. According to statistics, about 20 million tons of hydrocarbons are released into the atmosphere every year worldwide, of which paint and coating processes account for a large proportion. The amount of organic solvents emitted into the atmosphere during paint manufacturing is 2% of the amount of paint, and the organic solvents volatilized into the atmosphere during the coating process are 50% to 80% of the amount of paint.
In recent years, companies that have transformed to produce water-based paints have continued to emerge, and some companies have made continuous breakthroughs in water-based paint technology, and water-based paints have been continuously recognized and accepted in the market. With the introduction of relevant national and local policies, as well as the construction training of paint companies and the popular science propaganda of the media, it can be proved that the performance of water-based paints can be comparable to solvent-based paints and can meet the performance needs of the market. There are also online studies that point out that the water-based paint market in 2021 will reach US$78.24 billion, with an annual compound growth rate of 5%.
There is a reason why the water-based paint market is so hot. In recent years, there has been an environmental storm. In 2016 alone, thousands of micro-paint companies across the country were eliminated and closed because they violated environmental regulations. Today, with increasingly strict environmental supervision, Jiangsu, Shandong, Hunan, Sichuan and other provinces have successively introduced some policies, which will have a certain impact on related industries such as paint. The paint industry has always been considered a "three highs" (high pollution, high energy consumption, and high emissions) industry. When conducting a national environmental inspection, paint companies can only see the future by following the laws of social development and embarking on the road of green and environmentally friendly production.
In addition to the advantages of environmental protection, water-based paint has many other benefits. Especially for workers in the paint industry, the widespread use of water-based paint can make them less or not subject to the potential toxicity of organic paints and avoid the hidden dangers of fire. In terms of waste treatment, the garbage generated by general water-based paints is easier to be detoxified than solvent-based paints. From an economic point of view, water-based paints are more popular because water is a cheap and easily recyclable solvent among engineering solvents. Compared with organic solvents that are often affected by oil prices, water is an economically stable choice. As various water-based paints have become more and more popular, many scientific researchers in the field of paints have increasingly devoted themselves to the research of water-based paints. In addition, my country's water-based paint market is widely optimistic, and companies have established water-based paint production bases to increase the proportion of water-based paint products. The demand for water-based paint in the Chinese market is increasing, and it has become an indispensable auxiliary material in the construction, furniture, automobile and other industries. In addition, with the growing strength of China's paint industry, the water-based paint market is bound to be driven by the overall upward trend of paints and get a share.
As a new type of paint with polymer resin as the base material, water as the solvent in production, and water diluted in construction, water-based paint is more environmentally friendly than traditional solvent-based paints, and has low toxicity and low odor, which can create a green and healthy environment for people. Let's analyze the advantages of water-based paint and the disadvantages of water-based paint promotion together.
● Advantages of water-based paint:
1. Water-based paint uses water as a paint solvent, which can greatly eliminate the risk of fire during construction, reduce air pollution, and improve the construction environment. It can not only save a lot of resources, but also reduce the pollution index in the atmosphere.
2. It has a high tolerance for the moisture content of the substrate, has good adaptability on substrates with relatively high moisture content, and has stronger adhesion than oil-based paint.
3. The spraying tools can be directly rinsed with clean water after completion, reducing the loss of cleaning solvents and air pollution.
4. The electrophoretic coating has high corrosion resistance and salt spray resistance, and the coating has good flatness. A certain thickness of coating can be applied to the inner cavity, welds, and edges and corners, which has good protection.
● Disadvantages of water-based paint promotion:
1. As the current environmentally friendly paint market is still immature, compared with the rapidly developing paint industry, my country's water-based environmentally friendly paint industry has been tepid. The production process of environmentally friendly paints has strict requirements and high costs. Most domestic water-based paint projects cannot achieve the coating effect of traditional paints and are easily affected by the environment. Therefore, the technology still needs to be continuously improved.
2. Consumers are not aware of environmentally friendly paints. Although water-based paints have been accepted and recognized by consumers, consumers' environmental awareness is lower than their economic awareness. Environmentally unfriendly products occupy most of the consumption share of the paint market, which restricts the development of environmentally friendly paints.
In short, water-based paint is a new type of environmentally friendly paint compared to oil-based paint. Its environmental protection principle is to use water instead of the diluent in traditional paints. Compared with traditional paints, the biggest feature of water-based paint is that it uses water as a diluent. Nearly 50% of it is water that is harmless to the human body and the environment. It does not contain toxic and harmful substances such as benzene, toluene, xylene, and formaldehyde, which can minimize the pollution to the natural environment and the harm to human health. At the same time, because 50% of it is water, water-based paint has low toxicity and low odor. During the construction process, it is non-flammable and non-explosive, and has a high safety factor.
As a new energy-saving and environmentally friendly material, water-based paint complies with the national industrial policy of energy conservation, emission reduction, low-carbon and environmental protection, and is an industry encouraged and supported by the state. With the introduction of a series of environmental protection policies in my country, it will continue to promote the rapid development of environmentally friendly coatings, and many domestic companies have also joined the market of environmentally friendly coatings. Upgrading and transforming, increasing investment in coating technology research and development, and constantly overcoming related problems, the current market share of water-based products has increased year by year, and there is even a trend of acceleration. In the future, the water-based environmentally friendly coating industry will develop more rapidly.
