Today, Rushan Beihua new materials to bring you in the production of polyethylene wax in the performance and benefits.
Low molecular weight polyethylene compared with high molecular weight polyethylene, low melt viscosity, with wax properties, commonly known as polyethylene wax. Polyethylene wax chemical stability, feel smooth, good wear resistance, high hardness, different ways to join the system can give different shine, as a dispersant, anti-wear agent, brightener, matting agent, slip agent, In the ink, paint industry widely used. However, due to the high softening point of polyethylene wax, non-polar characteristics of strong, difficult to emulsify, coupled with ink, paint industry, wax emulsion particle size, emulsifier dosage requirements, therefore, high melting point (higher than 120 ℃), ultra-fine Particle size (less than 100nm) of the development of polyethylene wax emulsion has been the domestic ink, paint industry, technical difficulties.
Jinhua Kang Hong water wax Technology Co., Ltd. in Beijing University of Chemical Technology with the support of the successful development of the AF series of synthetic wax emulsion products, in the field of ink, paint applications. The following is the characteristics of wax emulsion and in the application of water-based ink characteristics.
1, water-based ink commonly used wax characteristics and join the way
Water-based ink wax commonly used wax, microcrystalline wax, palm wax and polyethylene wax (synthetic wax), which, palm wax is "the king of wax", hard, tough, high gloss, feel good, easy to emulsify, Is the best combination of natural wax in a good performance. Melting range of 90 ~ 145 ℃, was white translucent, odorless and tasteless, strength, toughness and superb, easy to modify and get a variety of special properties, the price is lower than the palm wax, has become the preferred paint industry, ink industry. Wax in the ink in the way of dispersion in Table 1 (slightly), microstructure shown in Figure 1 (slightly).
2, AF series of polyethylene wax emulsion in the application of water-based characteristics
(1) smooth, abrasion resistance, scratch resistance
Wax emulsion into the water-based ink, the wax in the filming process drift to the coating surface, evenly dispersed in the coating on the formation of wax protective layer. As the AF series of high hardness of the selected wax, reducing the friction coefficient; so the coating wear and smooth excellent, but also changed the direction of the coating force to improve the coating scratch resistance , As shown in Figure 2 (omitted).
(2) the effect of emulsion particle size on the gloss of the coating
Visible light wavelength of 400 ~ 700nm, when the polyethylene wax particle size is less than 1/2 of the visible wavelength, that is ≤ 200nm, will produce light diffraction, which can improve the coating gloss. It is generally believed that the larger the change of particle size of wax particles, the more obvious the gloss effect; In addition, the coating gloss and wax crystallinity also have a certain relationship. AF series of wax emulsion broke through the emulsion technology difficulties, wax particle size has reached the nano-level, as shown in Figure 3 (omitted), is the best glossy ink system surface protection agent.
At present, the domestic wax emulsion in the basic performance has been and imported brand-name products, and reflects the obvious cost advantage. With the rapid development of water-based ink industry, should further improve the quality of wax products and production to meet market demand.
