Advances in the technology of water-based wax additives and wear-resistant applications in coatings

With the improvement of environmental protection requirements in the coating industry, the application and exploration of water-based coatings are gradually deepening. Water-based wax additives are important additives for water-based coatings, for coatings to provide wear-resistant, anti-stick, anti-scratch, anti-sinking, hydrophobic, polishing and other roles, commonly used raw materials including polyethylene wax, paraffin, Feto wax, Mondan wax, polyteet fluoroethylene wax, etc., can be used alone or compound, performance varies, the use of different emulsification formulations and processes, the application in the paint is also different.
years, high-performance raw materials continue to introduce and domestic, domestic manufacturers from the simple imitation of foreign products to market demand for independent innovation

. The new emulsification technology includes a large number of applications such as interface emulsification, low-energy emulsification and micro-emulsification. In particular, the paint industry continues to expand demand and improve requirements, domestic water-based wax products have made a lot of progress.
emulsification method produces high melting point polyolefin wax water dispersions
polyethylene wax, polypropylene wax, Feto wax can be manufactured into 4-10 m particle size of water dispersion, in water-based coatings to improve scratch resistance, anti-wear resistance. Emulsification method to produce wax water dispersion to overcome the dispersion problem in the coating, by high temperature molten wax (oil) under the high shearing effect of emulsifying agents and equipment to form a reasonable particle size dispersion particles, cooling into solid particles suspension emulsion. Its spatial structure is similar to the emulsion beam, emulsifying agent oil-based solution in wax particles, hydro-water-based and water-like formation of a good combination, thereby greatly improving the dispersion stability of the dispersion.

wax and other materials constitute composite materials
In fact, the so-called use of wax surface treatment of the light-eliminating powder is the water-based wax to the anti-light powder coating composite materials. This type of anti-lightener is widely used in the coatings industry.
patent invented by Nanjing Tianshi - wax-water-based dispersion of nano-silicon dioxide and its preparation method and use (CN201310441008.7), using nano-grade silicon dioxide particles through silane even The organic inorganic composite water-based dispersion formed by the additive load on the micron-grade wax particles is used as an additive for coating, ink, leather coating and fabric finishing, and plays the role of friction resistance, stain resistance, wear resistance, lighting, easy scrubbing and so on. There are also reports on the use of wax as a carrier for new functional materials such as phototalysts and graphene.
