Problems solved by technology

[0004] In addition, when the emulsified high-density polyethylene wax emulsion achieves a transparent effect, the emulsifying performance of the emulsifier is often required to be high, and the more economical and better-performing emulsifiers will have the problem of being banned for environmental protection: such as NP, OP series emulsifiers

Abstract

The invention relates to the field of petrochemical industry, in particular to high gloss wax emulsion for waterborne varnish printing, and a preparation method of the high gloss wax emulsion. The high gloss wax emulsion for waterborne varnish printing is prepared from high density polyethylene wax, Fischer-Tropsch wax, an emulsifying agent, alkali, a wetting dispersant and water; the high densitypolyethylene wax and the Fischer-Tropsch wax are mixed and emulsified; the molecular weight of the high density polyethylene wax is within a range of 500-5000, and the molecular weight of the Fischer-Tropsch wax is within a range of 500-1000; the emulsifying agent is an environment-friendly emulsifying agent which has a cyclic structure and has a carbon number of 10-35. According to the method, the wax emulsion is prepared by mixing and emulsifying the polar oxidized polyethylene wax and the non-polar Fischer-Tropsch wax, and is applied to the waterborne varnish printing, so that a high oilyfeeling and glossiness is provided for varnish, and the surface of the varnish has a high degree of fineness; furthermore, due to smoothness of the Fischer-Tropsch wax, the viscosity, caused by acrylate, of the varnish is greatly reduced, the surface friction coefficient is reduced, and the wear resistance and the scratch resistance are improved; the environmentally friendly emulsifying agent is used and water is used as a solvent, so that pollution caused by adopting NP / OP emulsifying agents in the past is avoided.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a high-gloss wax emulsion for water-based varnish printing and a preparation method thereof. Background technique [0002] As an important special wax product, wax emulsion is a homogeneous liquid containing wax and water. It does not need to be heated and melted or dissolved in certain solvents when it is used. It has stable performance, uniform film formation and good coverage. , easy to mix with other substances in aqueous solution or emulsion, and non-toxic, non-corrosive, simple production process, easy to store, easy to use, cheap, etc., widely used in wood-based panels, paper, polishing agents, agriculture, ceramics , water-based products for textile, rubber and construction industries. [0003] However, various types of wax emulsions, due to the use of different types of waxes such as high-density polyethylene, modified polyethylene, low-density polyethylene, Fische...
