Problems solved by technology

[0002] At present, although the binder prepared by ordinary rosin phenolic modified resin is widely used in ordinary offset printing inks, it has poor solubility and poor stability in non-aromatic kerosene, and the viscoelasticity cannot meet the printing requirements. The prepared non-aromatic soybean oil is thermoset Rotary inks

Abstract

The invention relates to a preparation method of high-viscoelasticity coupling material for non-fragrant soybean oil thermosetting web offset ink, comprising the following steps: in a standard normal-pressure kettle, adding 40+/-1 parts of non-fragrant ink oil and 12+/-0.5 parts of industrial soybean oil into the kettle according to parts by weight; adding 43+/-1 parts of high-viscosity rosin modified phenolic resin while stirring for raising the temperature; keeping warm at the temperature of 180+/-2 DEG C until resin is totally dissolved; stopping heating, and adding 4+/-1 parts of non-fragrant ink oil; adjusting viscosity to 65000+/-2000 MPa.s/25 DEG C by the non-fragrant ink oil; adding 0.73+/-0.01 part of gelling agent, and reacting at the temperature of 175+/-2 DEG C; sampling and detecting per 0.5 hour; when viscosity is 500000+/-50000 MPa.s/25 DEG C, stopping temperature reduction reaction to obtain the product; and at the temperature of 135+/-5 DEG C, filtering and packaging according to the normal ink coupling material production procedures. The high-viscoelasticity coupling material of the invention has favourable viscoelasticity and dissolubility in non-fragrant kerosene, has favourable performance in non-fragrant soybean oil thermosetting web offset ink and can satisfy high-speed and exquisite thermosetting web offset ink printing. The high-viscoelasticity coupling material has favourable dot reproduction, printability, simple technology and obvious effect.

Description

technical field [0001] The invention relates to the field of synthetic resins, in particular to a method for preparing a high-viscosity elastic binder for non-aromatic soybean oil offset printing heat-setting rotary ink. Background technique [0002] At present, although the binder prepared by ordinary rosin phenolic modified resin is widely used in ordinary offset printing inks, it has poor solubility and poor stability in non-aromatic kerosene, and the viscoelasticity cannot meet the printing requirements. The prepared non-aromatic soybean oil is thermoset Rotary inks have poor printability, which can easily cause printing failures such as ink flying, and can only print low-end printed products at low machine speeds. Since the gelling agent requires low temperature and dispersion, the preparation process is complicated, energy is wasted, the production cycle is long, and the production cost is high. [0003] Therefore, to provide a method for preparing a high-viscoelastic...
