Solid wood furniture has always been the leader in the furniture industry, popular for many years and enduring. As people's environmental awareness continues to increase, solid wood furniture has become more and more popular.
However, solid wood furniture has failed random inspections, including excessive formaldehyde content, which are also common topics in the furniture industry. In many cases, the main reason is still the wood paint.
We all know that the common furniture is currently divided into two categories: solid wood furniture and panel furniture, but solid wood furniture is relatively weak in texture. In order to prevent solid wood from deforming or cracking, wood paint is needed for protection.
Wood paint contains substances such as benzene that are harmful to the human body. Therefore, wood paint and furniture environmental protection have a significant relationship. Even solid wood furniture may not be environmentally friendly. It depends on what paint is used!
But most people pay attention to appearance, price, etc. when choosing wooden furniture, but few people pay attention to the paint surface of wooden furniture. If the wrong paint is chosen, even pure solid wood furniture will release various harmful substances and endanger health.
What is wood paint? Wood paint is all the paint that can be used on the surface of wood. It can be divided into three categories: water-based paint, oil-based paint and wood wax oil. It has two main functions: one is to make furniture beautiful, and the other is to protect furniture and reduce its impact on pollution or dry-wet changes. The surfaces of solid wood veneer furniture, multi-layer solid wood composite, three-layer solid wood composite, and pure solid wood furniture on the market are all painted (of course, they are painted during production).

Water-based paint is an environmentally friendly water-based paint. Water-based paint is a paint that uses water as a dispersion medium. It is non-toxic and pollution-free. Regarding water-based paint, many people have prejudices.
It is believed that water-based paint is not as good as oil-based paint in hardness, wear resistance and scratch resistance. In fact, water-based paint is also divided into three, six, and nine grades: low-end water-based paint uses acrylic acid as the main raw material, and its various performances are relatively low, which has attracted a lot of criticism for water-based paint. Mid-range water-based paint uses a compound of acrylic acid and water-based polyurethane as the main raw material, which improves the hardness, but the chemical properties (such as poor alcohol and alkali resistance) are still relatively low. High-end water-based paint uses acrylic modified water-based polyurethane as the main raw material. Both physical and chemical properties are very strong, and some indicators even exceed oil-based paint.

Oil-based paint solvent-based paint (oil-based paint/paint) is a paint with organic solvent as the dispersion medium.
Although the environmental performance is not good, oil-based paint still has many inherent advantages: low purchase price, good brushability, flexible coating film, good permeability... This is also the main reason for its high acceptance. Oil-based paint is divided into many types, such as PU paint, NC paint, UV paint, and PE paint. All are oil-based paints... Don't be scared when you hear others talk about these high-sounding words in the future.

Wood wax oil The main component of wood wax oil is vegetable oil, and iron oxide and other pigments are used for coloring. From the raw materials, toxic and harmful volatiles such as benzene and formaldehyde are eliminated, so its environmental performance exceeds that of water-based paint.
And whether from the perspective of manufacturing or use, wood wax oil consumes less environmental resources and is more beneficial to ecology and health. But one difference is that wood wax oil cannot cover up ugliness. It has no covering power, and will deepen the color difference of the wood itself, making the wood's furuncles and other defects more obvious, but many people like this now.
How to distinguish wood wax oil from paint? Because wood wax oil is an open coating method, it can fully display the details of the wood and retain the natural uneven texture of the wood, so it feels rough. The paint will form a paint film on the surface of the wood, and when the paint film is thick to a certain extent, it will produce a higher gloss. Therefore, it feels smoother and looks more glossy. However, you can't feel the natural texture of the wood when you touch it. Compared with the wood painted with wood wax oil, it feels fake.
In short, there is no need to say much about the degree of environmental protection: wood paint > water-based paint > oil-based paint. So not all solid wood furniture is environmentally friendly, there is a world inside, I hope everyone will analyze it carefully!
