Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to an ultraviolet-curing urethane acrylate coating and a preparation method thereof.
Background
The light-cured coating is a liquid formula added with a photoinitiator by irradiating a light source with certain intensity, and the photoinitiator absorbs light quanta to generate active groups to initiate polymerization reaction, so that liquid resin is instantly converted into a solid film. Photocured coatings have gained rapid development due to the properties of the photocuring technique itself, as compared to conventional naturally dried or thermally cured coatings. First, the photocuring is performed only at normal temperature, and the construction unsuitable for the product of the heat drying method can be satisfied. Second, the photo-curing technique enables coating quality, such as mechanical properties and gloss, to be brought to a higher level, in addition to improving productivity and saving energy consumption. Third, because a "solventless" system is used, expensive waste disposal facilities do not have to be installed during the manufacturing application.
The photocureable coating mainly comprises four parts: photoinitiator, resin prepolymer, reactive diluent and auxiliary agent. Prepolymers, also known as photosensitive resins, are film-forming substances which are present in considerable proportions in the overall system and have a decisive influence on the properties of the coating film. There are two main types: radical polymerization type resins and cationic polymerization type resins.
Among all UV photocureable coatings, the polyurethane acrylate coating has the advantages of high hardness, good luster, strong toughness and yellowing resistance, and is the most widely applied UV photocureable coating. Although the polyurethane acrylate coating has the advantages of good adhesion, high surface hardness, good gloss and strong toughness, the oil stain resistance is generally poor.
The principle of stain resistance: the stain resistance of organic coatings is mainly related to the surface energy and surface characteristics of the coating, neglecting the influence of external factors. The smaller the surface energy, the better the stain resistance because the contaminants are generally oil stains caused by water, which accumulate to a large extent, and the stains are relatively less likely to form as long as water droplets do not readily adhere thereto. Therefore, the micro-rough structure is formed on the surface of the coating, and the oil stain is not easy to adhere to the surface of the coating by increasing the contact angle between the pollution source and the coating.
The traditional solution for improving the stain resistance of a paint film is to use a fluorine-containing auxiliary agent or add inorganic nano particles in the preparation process of the paint to improve the stain resistance effect after film formation, but the method only has a transient effect and poor stain resistance durability, and mainly shows the following two points: on one hand, under the condition of high temperature and high humidity, the surface of the pattern layer is easy to damage, and the fluorine-containing auxiliary agent is easy to migrate, so that the stain resistance and stain resistance are not durable; on the other hand, if the coating is applied to floor paint, the fluorine-containing auxiliary agent is easy to fall off under the environment of long-term friction, so that the stain resistance and stain resistance of a paint film are greatly reduced, and the performances of hydrophobicity and oil resistance are also poor. Therefore, there is an urgent need to develop a urethane acrylate coating having excellent durability and oil stain resistance.
