Embodiment 1

[0035] Offset printing ink (rotary printing ink), the composition and content of ink raw materials (parts by weight): rosin 15, PS12, acrylic acid ester 5, emulsifier 7, carbon black 18, talcum powder 3, high boiling point kerosene 20, water 20

[0036] Break waste polystyrene plastic PS into pieces, dissolve rosin with high boiling point kerosene (distillation range 300-400 degrees), put the broken PS into eutectic, when PS is completely dissolved, add pure water, emulsifier fat Alcohol polyoxyethylene ether [RO(CH2CH2O)nH], use a high-speed dispersing emulsifier to disperse the PS that has been dissolved into extremely small particles in the water / oil emulsion. Add acrylic resin and carbon black, mix and grind to obtain offset printing ink. The ink has been used in Guangxi Traffic Safety News, Nanning Daily, Guilin Daily, Liuzhou Daily and Beihai Daily since 2001, and the printing quality is very good.

Embodiment 2

[0038] Offset printing ink (rotary printing ink), ink raw material composition and content (parts by weight): rosin 10, PS 18, acrylic acid ester 7, emulsifier 7, carbon black 18, talcum powder 3, high boiling point kerosene 20, water Servings 20.

[0039] Break the waste polystyrene plastic PS into pieces, dissolve the rosin with high-boiling kerosene (distillation range 300-400 degrees), put the broken PS into eutectic, when the PS is completely dissolved, add pure water, emulsifier poly Ethylene oxide, using a high-speed dispersing emulsifier, evenly disperses the PS that has been dissolved into extremely small particles in the water / oil emulsion. Add acrylic resin and carbon black, mix and grind to obtain offset printing ink. Since 2001, this ink has been used in Guilin Printing Factory, Guangxi Elderly News, and Youjiang Daily, and users have reported that the printing quality is very good.

Embodiment 3

[0041] Printing ink (embossing ink), ink raw material composition and content (parts by weight): rosin 8, PS 12, acrylic acid fat 6, emulsifier 7, golden red 12, talcum powder 3, high boiling point kerosene 16, water Servings 25.

[0042] Break waste polystyrene plastic PS into pieces, dissolve rosin with high boiling point kerosene (distillation range 300-400 degrees), put the broken PS into eutectic, when PS is completely dissolved, add pure water, emulsifier fat Alcohol polyoxyethylene ether [RO(CH2CH2O)nH], use a high-speed dispersing emulsifier to disperse the PS that has been dissolved into extremely small particles in the water / oil emulsion. Add acrylic resin and Jinguanghong, mix and grind to obtain offset printing ink. The ink has been used in Guangxi Pingle Printing Factory and Pingle Daily since 2003, and users have reported that the printing quality is very good.

Abstract

A water soluble printing ink and its production are disclosed. The ink consists of pine resin 5-20 proportion, polystyrene 1-20 proportion, acrylate 2-8 proportion, pigment 4-20 proportion, emulsifier 1-10 proportion, mineral spirits 10-30 proportion, assistants 1-10 proportion and water 20-70 proportion. The process is carried out by adding solvent, emulsifier, pigment and filler into waste polystyrene. Its advantages include stable performance, good color fixing ability, fast dry speed, low cost and no environmental pollution.

Description

technical field [0001] The invention relates to an ink, in particular to a water-soluble printing ink product produced from waste plastics as a raw material and a production method of the ink Background technique [0002] Ordinary inks are divided into offset printing inks, custom writing inks, stereotyped printing inks, speed printers, digital printing inks and other varieties according to their viscosity and performance requirements. This ink is mainly made of modified natural resin and petrochemical raw materials. Synthetic resin, vegetable oil, solvent oil composed of linking material, pigments, additives, and fillers. When using this ink, it needs to be adjusted with resin oil, varnish and solvent oil. The production price is expensive and the production cost is high. cause environmental pollution. [0003] In recent years, some scientific journals have disclosed some water-soluble printing inks and their production methods, such as: 1. [Title] Synthesis and Characteri...
