Production method of ink wax

Abstract

The invention discloses a method for preparing ink wax. The method comprises carrying out hydro-conversion on an F-T synthesis product as a raw material under action of a catalyst, carrying out distillation on the hydrogenation product to obtain a component as a sweating raw material for a distillation range and carrying out emulsification and sweating to obtain a desired product. Based on the ordinary sweating method, airflows pass through a wax layer and carry away a liquid component in the sweating process so that a solid component and the liquid component are forcibly separated, and preferably, the sweating raw material and water or a salt solution are emulsified so that the liquid component can be fast discharged. The method has the advantages of low equipment investment, simple production process, low operation cost, safety, energy saving and no solvent pollution. The product has a narrow melting range and can be used as ink wax.

Description

technical field [0001] The invention belongs to the technical field of special wax production, and in particular relates to a production method of ink wax, especially a production method of wax used for hot-melt ink. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate through printing. Inks are widely used in various printings such as books, periodicals, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. [0003] Hot melt inks, or phase change inks or coldset inks, are solid at ambient temperatures and liquid at the higher temperatures at which inkjet printing devices operate. When the inkjet printing device is in operation, liquid ink droplets are ejected, and when the ink droplets directly or indirectly contact the surface of the recording substrate, they a...

Problems solved by technology

[0014] The sweating process is an intermittent operation, and the product yield is low and the production cycle is long. However, the sweating process has the advantages of less investment, simple production process, low operating cost, safe production process, energy saving and no pollution to the environment. At present, there are still some Manufacturers are using this method to produce soap wax products

[0015] Over the years, the sweating method has been developed in terms of production equipment and technology, such as CN89214332 (vertical square multi-section sweating tank), CN94223980.6 (dish-type sweating device), CN98233254.8 (paraffin sweating tank), CN200920033500. X (new paraffin sweating tank), CN201210508905.0 (a high-efficiency paraffin sweating device), CN201320127680.4 (tubular paraffin deoiling device), etc., have made improvements in sweating production equipment; CN91206202 (a high-efficiency paraffin sweating tank ) Improvements have been made in the sweating process, but these improvements still cannot produce wax products for inks with a melting point of about 70 °C
