Polyethylene wax is a kind of polyethylene with low molecular weight. Its melt viscosity is very low and has the characteristics of wax. The general degree of polymerization is 100 ~ 300 and the number average relative molecular weight is 2000 ~ 10000 It has stable chemical properties, smooth feel, good wear resistance and high hardness. It is widely used in ink, coating, shoe wax, textile and other industries Polyethylene wax micro lotion, which is prepared by heating and emulsifying polyethylene wax in aqueous system, has important application value in textile industry It has strong film-forming property and can significantly reduce the friction coefficient of the fiber surface, so it can be used as a smoothing agent; It has a high melting point and can be used as a softener for high-speed sewing threads; It has good flexibility and can be used as spinning oil or sizing agent Generally, the amount of emulsifier is large and the solid content of micro lotion is low Emulsified wax products with high solid content have the advantages of high production efficiency, low transportation cost, fast drying and low energy consumption The preparation of emulsified wax products with high solid content, good fluidity, low amount of emulsifier and nano-sized ultrafine particles is still a difficult problem to be solved in this field.
The formula of polyethylene wax ultra-fine lotion is: polyethylene wax 40%, emulsifier 6.4%, alkaline additive KOH 0.31%, and the rest is water. It is produced by high temperature and high pressure direct emulsification Polyethylene wax, emulsifier, KOH and water are added into the reactor at 130 ℃ and emulsified at a stirring speed of 60 r/min for 40 min. after natural cooling, a yellowish and transparent wax lotion can be obtained.
The application of polyethylene wax ultra-fine lotion in fabric waxing process can not only give the fabric good hand feeling, but also greatly improve the fabric strength, which has excellent practicability.
