Shoe coating dispersant: the hero behind the bright and beautiful shoes
Shoes are an indispensable item in our daily life, and a pair of beautiful and durable shoes cannot be separated from the modification and protection of shoe coatings. In the production and application of shoe coatings, there is a key auxiliary agent that is often overlooked, which is the shoe coating dispersant. Although it is inconspicuous, it plays a vital role in shoe coatings, and its application range is widely involved in multiple links of shoe production.
Shoe coatings are usually composed of pigments, resins, solvents and various auxiliary agents. Among them, pigments are the key components that give shoes color, but pigment particles tend to gather together to form larger particle clusters. If these particle clusters cannot be evenly dispersed in the coating, it will cause uneven color, precipitation, rough surface after coating, etc., which seriously affects the appearance and quality of the shoe. The role of the shoe coating dispersant is to disperse these aggregated pigment particles so that they form a stable and uniform dispersion system in the coating.
The application range of shoe coating dispersants is first reflected in shoe coatings of various materials. Whether it is a sole made of rubber as the main material or a shoe upper made of leather or synthetic leather, the paint used needs to be added with a dispersant. For rubber sole paint, the properties of rubber itself are relatively special, and the pigments in the paint are difficult to disperse. Dispersants can help the pigment particles better blend into the paint, ensure that the color of the sole paint is uniform, and it is not easy to fall off after coating, thereby improving the wear resistance and aesthetics of the sole. Leather and synthetic leather upper paints have higher requirements for color. Dispersants can fully disperse the pigments, so that the uppers present bright and uniform colors, while ensuring a good combination of the paint and the upper material, and enhancing the adhesion of the coating.
In the process of shoe material coating with different processes, shoe material coating dispersants also play an important role. For example, in the spraying process, the paint needs to have good fluidity and uniformity so that it can be evenly coated on the surface of the shoe material through a spray gun. If the pigments in the paint are unevenly dispersed, it will cause the spray gun to be blocked, or defects such as spots and stripes will appear on the surface of the shoe material after coating. Dispersants can keep the paint in a stable dispersed state, ensure that the spraying process goes smoothly, and obtain a smooth and smooth coating. In the brushing and rolling processes, the pigments in the paint also need to be evenly dispersed. Dispersants can reduce the appearance of brush marks and rolling marks, making the coating on the surface of the shoe material more uniform and beautiful.
In addition, in special functional shoe material coatings, shoe material coating dispersants are also indispensable. For example, shoe material coatings with functions such as waterproof, antifouling, and antibacterial contain various functional additives in addition to pigments. Dispersants can not only disperse pigments, but also help these functional additives to be evenly dispersed in the coating, ensuring that every part of the shoe material can have the corresponding function, rather than uneven distribution of functions.
It can be said that although the shoe material coating dispersant does not directly determine the function and style of the shoe material, it indirectly affects the appearance, performance and service life of the shoe material by ensuring the quality of the shoe material coating. In many links of shoe material production, it plays a role silently and is the hero behind the scenes who makes the shoe material glow brightly.
