The difference between water-based paint and oil-based paint
1. Different raw materials
The so-called oil-based paint is actually a kind of paint with more oil. It has more oil substances and can play a good decorative and protective role. However, some other materials such as anti-rust paint and blending paint are added, which makes the oil-based paint contain a large amount of harmful substances. The smell is relatively strong and has certain harm to the human body. The raw materials of water-based paint are different. Not only does it not have a large amount of oil items, but it uses water as a diluent for water-based paint. It is non-toxic and harmless, will not cause any harm to the body, and will not harm the environment. Water-based paint is more popular.
2. Different production
The production methods of the two are different. Oil-based paint has left a deep impression in people's minds. With the deepening of the concept of environmental protection, people began to look for better environmentally friendly products to replace oil-based paint. Water-based paint came out at this time. It uses water as a diluent and has no pungent smell, which makes people have an unusual good impression on water-based paint. The production process of oil-based paint is relatively complicated, and it has to go through many procedures and equipment for step-by-step processing. Compared with oil-based paint, the production of water-based paint has reduced many links in terms of process procedures and equipment alone.
3. Different hazards
People's understanding of oil-based paint is already deeply rooted, but many people still know very little about real oil-based paint. Even those who have been engaged in the paint industry for more than ten years do not know much about the hazards of paint. Generally, oil-based paint is used to paint the home, and it takes at least one month or more than three months before you can move in. In this process, although the smell of oil-based paint is gone, potential hazards still exist. The biggest feature of water-based paint is that it is harmless and there is no so-called dilution and volatilization, which is relatively safer.
4. Different characteristics
Characteristics of water-based paint: highly environmentally friendly water-based paint, no odor, even if there is odor, it is relatively low. During construction, the harm is not great, and there is no strong irritating smell; the coating of water-based paint has good corrosion resistance, wear resistance and heat resistance, which can effectively ensure the toughness of the paint film; a 100-degree Celsius high-temperature kettle can be placed on the surface layer of the water-based paint; it will not change color even under sunlight; it has anti-slip properties. Characteristics of oil-based paint: low price cost, more varieties, easy to produce, low production cost, and cheap oil-based paint.
5. Different prices
The price difference between the two is quite large. Compared with oil-based paint, water-based paint is much more affordable than oil-based paint, and its use is limited; although the price of oil-based paint is a little higher, its application range is relatively wide, such as building exterior wall painting, interior wall painting, home wall painting, industrial machinery surface painting, etc., ships, cars, etc.
What are the advantages and disadvantages
Water-based paint is easy to use and is not prone to common problems of oil paint such as bubbles; water-based wood paint has low hazards and little pollution; because it is a water-soluble paint, it is non-toxic, so it is environmentally friendly; water-based wood paint is not easy to turn yellow and has good water resistance; it can prevent rust, so there is no need to worry about rusting after encountering water, and it is very resistant to high temperatures, so very hot objects can be placed on it; it can be used at the same time with other paints such as latex paint.
Single-component water-based paint still has a certain gap with two-component oil paint in terms of hardness, high temperature resistance and other properties. If the hardness is not enough, scratches are easy to appear, affecting the beauty of the object. For example, a desk, if you accidentally leave marks on it with your own nails, then the desk will not look as good as it did at the beginning. Or on the floor, sharp objects on the shoes, especially some iron decorations on women's shoes, can easily scratch the floor with poor hardness. It also hinders the development of water-based paint. 2. Oil-based paint
Good protection function, of course, oil-based paint is anti-corrosion, waterproof, oil-proof, chemical-resistant, light-resistant, and temperature-resistant. Objects are exposed to the atmosphere and are corroded by oxygen, moisture, etc., causing metal rust, wood decay, cement weathering and other destructive phenomena. Applying oil-based paint on the surface of the object to form a protective film can prevent or delay the occurrence and development of these destructive phenomena and extend the service life of various materials. Therefore, protection is a major function of oil-based paint.
The decorative function is powerful. Oil-based paint has the characteristics of color, gloss, pattern and flatness. Objects of different materials are coated with oil-based paint to obtain a colorful and gorgeous appearance, which plays a role in beautifying the human living environment and makes a contribution to human material life and spiritual life that cannot be ignored.
Oil-based paint also has marking, anti-fouling, insulation and so on. For modern oil-based paint, this function is increasingly showing its importance compared with the first two functions. Some modern oil-based paint varieties can provide a variety of different special functions.
Oil-based paint has a strong odor and contains a lot of harmful substances in the gas, which is harmful to human health. Generally, after 1-2 months of use, the strong irritating odor evaporates to almost no odor. It uses banana water and thinner as diluents and contains a lot of harmful carcinogens such as benzene and xylene. After reading the article, everyone also knows the difference between water-based paint and oil-based paint, and the advantages and disadvantages are clear at a glance, which can help you choose paint better.
