When we decorate, we often use various kinds of paints. In addition to wall paints such as latex paints, we also use wood lacquers for carpentry. Commonly used wood coatings are called wood lacquers and are used exclusively for wood products. A kind of resin paint, can be divided into two kinds of water and oil. People often say that water-based paint is more environmentally friendly and healthy, but in fact, oil-based wood paint still dominates the market. Why does this happen? A word to describe: water-based paint health and environmental protection, oil paint strong and durable. So, what are the differences between wood paints, water-based paints and oil paints ? We will now introduce the difference between water paint and oil paint in detail! First, from the perspective of health and environmental protection 1, water-based wood paint The environmental indicators of wood lacquers mainly look at the data content of VOCs. The lower the value, the more environmentally friendly. The waterborne wood paints use water as the medium for the dispersion medium. The main component is the composition of pyruvic acid and polyurethane. The content of VOC is far below the national environmental protection index, that is, the VOC content is less than or equal to 200g/L. Water-based paint with water as a dispersion medium, has a certain degree of flame retardant, reducing the danger of fire. The odor of waterborne wood lacquer is also very small. After brushing, it dries quickly and is truly non-toxic, odorless, healthy and environmentally friendly. 2, oily wood paint Oily Wood Coatings uses organic solvents as the dispersion medium. These organic solvents mainly contain hydrocarbon compounds. The rest are also volatile organic compounds such as ketones, alcohols, glycols, ethers, esters, and nitro-branched compounds. The hazards of oily wood paints are mainly from these volatiles. There are many kinds of oily wood lacquer, including lacquer, varnish, lacquer, polyurethane paint, polyester lacquer, UV-curable wood lacquer, etc. Among them, polyester lacquer and nitrolacquer have the highest toxicity and high benzene content. , formaldehyde, xylene and other toxic substances, and these toxic substances are also highly flammable, it is easy to cause fire. Oily wood paints have volatile organic solvents. Toxicants can easily become irritating and pungent. Second, from the perspective of physical performance 1, water-based wood paint Waterborne wood coatings have a hardness of between 1-2H when fully dry, and their hardness is slightly inferior to that of oily woodware. On the touch of the paint face, waterborne wood coatings are used due to the thin coating and “virtual†"Texture" technology, water-based wood lacquer feel is still very full; In addition, waterborne wood lacquer also has the advantages of resistance to yellowing, wear, durability. 2, oily wood paint The hardness of oily wood paint film is generally higher than that of waterborne wood paint, but it is also due to the hard paint film of oily wood paint, so it is easier to crack and fall off. Oily wood lacquer is easy to be colorful and full of touch. However, in the oil paint, the nitrocellulose paint has the worst color and feel, and because it needs to be applied more than ten times, the hardness of the paint film is also not good. In oil paints, nitrocellulose paints and polyester paints have the disadvantages of easy yellowing, easy collision and whitening, and lack of durability. Third, from the perspective of construction technology 1, water-based wood paint The construction of waterborne wood coatings is very simple. Only a few layers can be diluted with water. The amount of water-based paint is small and the working hours are short. If the film is damaged, it can be covered directly for repair. Its storage is also very convenient, just stored in a cool place. 2, oily wood paint Compared to waterborne wood coatings, the construction of oily wood coatings is much more troublesome. Before the construction of the oil paints, it is necessary to add Tianna water or related curing agents and add them in a certain proportion. During the construction, especially the lacquer and polyester paints must also be constructed under the guidance of professionals and must be used up once. Brushing process, such as nitrocellulose paint need to brush more than ten times. If the paint film is damaged and the oil paint wants to be repaired, the old paint film must be sanded off before it can be repaired! With regard to the difference between water paint and water-based oil paint , Xiao Bian introduced it to everyone and hoped to help everyone! Can only say that the water-based paint and oil paint have their own advantages, the current process, the water-based paint can not completely replace the oil paint, everyone in the purchase, you can choose according to their own needs!
