Application effect of water-based wax lotion in leather finishing agent field

With the development of technology. Leather chemicals are increasingly being applied in daily life. This article introduces the application of water-based wax lotion in leather chemical industry. Emulsified liquid wax is divided into wax lotion, wax differential dispersion and wax dispersion. Wax with different particle sizes has different manufacturing methods and applications.

Wax lotion is used in leather industry: wax lotion is used as leather brightener, matting agent and hand feeling agent. At present, people have two kinds of requirements for the appearance of leather products. One is to increase the luster of leather, such as polished leather, patent leather, polishing effect leather, etc; Another approach is to avoid a glossy finish and give the leather a genuine leather feel and natural beauty. The former requires the use of brighteners, while the latter requires the use of matting agents.

When different wax lotion are selected for leather top coating, some can increase the luster or brightness of the leather, and some can produce the matting effect to present the leather charm. The size of wax lotion that produces brightness effect is very small, and the composition is relatively simple. A homogeneous and continuous wax film is formed on the leather surface. The film is smooth on the micro level, which has a strong reflection on the light wave, so it has a luster sense; The particle size of wax lotion that produces the extinction effect is large, forming a heterogeneous and micro uneven surface on the leather surface, which strongly scatters light waves. Scattering is the fundamental reason for the extinction effect of the extinction agent.

Wax lotion can be compounded with fatliquoring agent. A small amount of wax lotion can be compounded in fatliquoring agent to improve and enhance the effect of fatliquoring agent. Experiments show that 1%~5% wax lotion can be compounded into leather fatliquoring agent to improve the filling performance of fatliquoring agent, improve the permeability of fatliquoring agent in leather fiber, increase the waterproof performance of leather, and make leather feel smooth, soft and plump. As an additive for leather finishing, wax lotion were mainly prepared from beeswax, palm wax, insect wax, white wax, montane wax and other raw materials at the early stage. These waxes have limited production and high prices. In recent years, it has been reported that wax lotion are used as the main raw materials to prepare wax lotion for leather. With wax lotion as the main raw material, the price of wax lotion can be greatly reduced, and the use effect is not worse than that of natural wax. It is the main auxiliary agent for finishing high-grade leather, which can give the leather special brightness and wax feeling. Adding wax lotion into leather finishing agent mainly plays the role of filling coating, improving coating feel, abrasion resistance, anti sticking and increasing gloss. From the perspective of usage, it can be divided into soft wax and hard wax, which are respectively used for the bottom, middle, and top coating of leather; According to the ionic properties of lotion, they can be divided into non-ionic, anionic and cationic wax lotion, which can be used in combination with finishing agents with different ionic properties; Lotion type or solid emulsified wax can be made from the dosage form.

All products have good water solubility, stable lotion, and no layering and floating wax during long-term storage. It can be applied to the coating of various types of leather, with a soft and natural luster, a full and moisturizing feel, and can improve the friction resistance of the leather surface after coating.
