  • Comparison of water-based paint and oil-based paint

    Water-based paint is a paint that uses water as a thinner and does not contain organic solvents. It does not contain toxic heavy metals such as benzene, toluene, xylene, formaldehyde, and free TDI. It is non-toxic and non-irritating. , crystal clear, good flexibility and has the characteristics of water resistance, wear resistance, aging resistance, yellowing resistance, fast drying, easy to use and so on. Can be used on: wood, metal, plastic, glass, building surfaces and other materials. The oil-based paint refers to the paint made of organic solvents, containing volatile organic compounds (VOC), which are not only toxic to the human body and pollute the environment, but also flammable and explosive; some varieties also contain a large amount of formaldehyde, benzene, Toxic substances such as lead are "invisible killers" that pollute the environment and damage consumers' health. In addition, due to the composition of oil-based paint, its transportation conditions are quite harsh, but it is undeniable that the contribution made by oil-based paint in water-based paint is undeniable. Advantages of water-based paint: 1. Water-based coatings use water as a solvent, which saves a lot of resources; water-based coatings eliminate the risk of fire during construction; reduce air pollution; water-based coatings only use a small amount of low-toxic alcohol ether organic solvents, which improves the operating environment conditions. 2. Water-based coatings can be directly applied on wet surfaces and in humid environments; water-based coatings have good adaptability to material surfaces and strong coating adhesion. 3. The water-based paint coating tools can be cleaned with water, which greatly reduces the consumption of cleaning solvents. 4. The electrophoretic coating of water-based paint is uniform and smooth. Good flattening; inner cavity, welds, edges and corners can be coated with a certain thickness of coating, which has good protection; electrophoretic coating has the best corrosion resistance, thick-film cathodic electrophoretic coating The salt spray resistance can reach up to 1200h. Advantages of oil-based paint: 1. Anti-corrosion, waterproof, oil-proof, chemical resistance, light resistance, temperature resistance, etc. Objects are exposed to the atmosphere and are eroded by oxygen, moisture, etc., causing damage such as metal corrosion, wood decay, and cement weathering. The surface of the object is coated with oil-based paint to form a protective film, which can prevent or delay the occurrence and development of these damage phenomena and prolong the service life of various materials. . 2. Color, gloss, pattern and flatness, etc. Objects of different materials are coated with oil-based paint to obtain a colorful and colorful appearance. 3. Low price and easy to produce. Good brushing effect Disadvantages of water-based paint: 1. Water-based coatings have high requirements on the cleanliness of the construction process and the surface of the material. Due to the large surface tension of water, the dirt is likely to cause shrinkage holes in the coating film. 2. The water-based paint is highly corrosive to the coating equipment. It needs to use anti-corrosion lining or stainless steel material, and the equipment cost is high. 3. Baking water-based coatings have stricter requirements on construction environmental conditions (temperature, humidity), which increases the investment in temperature and humidity control equipment, and also increases energy consumption. 4. The latent heat of evaporation of water is large, and the baking energy consumption is large. Cathodic electrophoretic coatings need to be baked at 180°C; latex coatings take a long time to dry completely. 5. Organic co-solvents with high boiling point will produce a lot of oil fumes during baking, which will drop on the surface of the coating film after condensation to affect the appearance. 6. The water-based paint has the problem of poor water resistance, which makes the stability of the paint and the bath liquid poor, and the water resistance of the coating film is poor. Disadvantages of oil-based paint: 1. Slow drying and poor physical and chemical properties of the coating film 2. The harmful substances are high to the human body, and the harmful substances are continuously released and long-term volatilized. 3. It is easy to yellow, and the quality of the paint film is not good. Most of the paint films have been replaced by synthetic resin paints with excellent performance. 4. The paint film is harder and more brittle, and it is not easy to repair after damage. 5. Extremely flammable, must be stored separately in accordance with fire protection requirements Both oil-based paint and water-based paint have their own shortcomings. In decoration, it is necessary to consider where they can be used. The advantages and disadvantages must be clearly understood, so as to avoid the trouble of repainting.

  • Waterborne polyurethane applied to wallpaper composite

    Water-based polyurethane, also known as WPU, is more and more used in people's daily life, such as: dyeing, finishing, printing, etc. of various textile materials; coating of slow-release fertilizer, seed coating, etc.; building inner and outer walls of houses Latex paint, furniture paint for solid wood furniture, leather and synthetic leather on sofas, etc.; interior adhesives for buses, high-speed railways, private cars, car paint, etc....Wallpapers are widely used in the interior decoration of residences, offices, hotels and hotels It is widely used in developed countries and regions because it has the characteristics of various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price that other interior decoration materials cannot match. In the Chinese market, more and more young people now have an explosive growth in the choice of wallpaper when decorating. At present, the wallpaper composite glue on the market is mainly solvent-based glue, water-based styrene-acrylic glue, and bio-based glue. Solvent-based glue contains a lot of VOC and other unenvironmental factors, which are harmful to human health and will eventually be eliminated; water-based styrene-acrylic glue Due to the poor aging resistance of the benzene ring structure in the glue, it is not conducive to the long-term use of the product, and the characteristics of acrylic acid are hot, sticky, cold and brittle, which will cause inconvenience in transportation and construction in winter and summer; bio-based glue is prone to mold and bacteria, especially in Meiyu in Jiangnan Seasons have an immeasurable impact on the entire family environment and human health. The use of aliphatic water-based polyurethane as the main material of the wallpaper composite adhesive, supplemented by various environmental protection additives, has achieved good results. The specific process is as follows: Material: thick paper, thin paper Product: Waterborne Polyurethane Resin Apparatus: 30 micron wire rod, oven, heat press
