The polymerization inhibitor is the mixture of one or both of p-hydroxyanisole, 1,4-benzoquinone；
The lubricating grease can reduce the surface tension of ink system, thus make ink can be attached to after brushing as
On the substrate surface of the low surface tensions such as plastic film, promoted ink just coat after and low surface tension substrate combination energy
Power；
The preparation process of the offset litho printing ink includes the following steps:
Step 1: it is molten to weigh agitating and heating after UV solidified resin, filler, polymerization inhibitor are mixed with photoinitiator according to parts by weight
Melt, is uniformly mixed；
Step 2: pigment, antiwear assistant and lubricating grease are added in the molten mixture obtained suddenly one step up, sufficiently stir
Ink intermediate is made after mixing dispersion；
Step 3: will ink intermediate be added grinding device in carry out grinding so that ink is reached regulation fineness after obtain finished product
Offset litho printing ink.
The UV solidified resin is prepared by the processing of following raw material:
Epoxy acrylic resin 30-40 parts by weight, polyurethane acrylic resin 20-30 parts by weight, polyoxyalkylene acrylate resin
15-20 parts by weight, polyvinyl acetate 4-5 parts by weight and glass mixture 5-10 parts by weight；
The glass mixture is uniformly to be mixed by the glass fiber powder of 40%-60% with the glass fibre of 40%-60%
Composition, wherein the filament diameter of glass fibre is 3-10 μm, and the filament length of glass fibre is 1-3mm；
The processing technology of the UV solidified resin are as follows:
After S1, the pH to 3.5-4 by inorganic acid adjusting deionized water, silane coupling agent is added thereto, stirs to molten
Liquid clear makes silane coupling agent complete hydrolysis, and wherein the volume ratio of silane coupling agent and deionized water is 1:1.5-3, obtains
To silane coupling agent hydrolyzate, glass mixture is added in silane coupling agent hydrolyzate, after reaction 30-60min is mixed
It is separated by solid-liquid separation, glass mixture is stand-by in 110-120 DEG C of at a temperature of solidification drying；
S2, it will obtain being uniformly mixed in the polyvinylacetate particle of glass fibre addition solid state in previous step
Afterwards, it under the revolving speed of 200-300r/min, is heated with the heating rate of 2-3 DEG C/min, keeps polyvinylacetate gradually soft
Change dissolution to be homogenously mixed together to obtain additive with glass mixture；
S3, epoxy acrylic resin, polyurethane acrylic resin, polyoxyalkylene acrylate resin are uniformly mixed according to parts by weight
Heating and melting afterwards is uniformly mixed simultaneously, and adjusting revolving speed is that 200-300r/min is stirred and to being slowly added thereto
The additive that previous step obtains, object to be added continue to stir 30-60min after being added completely into；
S4, the molten mixture extruding pelletization that previous step obtains is obtained into finished product UV solidified resin.
UV solidified resin of the present invention makes the UV solidified resin tool of preparation using a variety of UV-cured resins as raw material
There are good tensile strength, hardness, flexibility, resistance to yellow and chemical-resistance, while by the way that polyvinylacetate is added thereto, gathering
Vinyl acetate is a kind of thermoplastic macromolecule material, can reduce the cure shrinkage of acrylic materials, while also benefit
Disperse glass mixture with the property of the watery fusion of polyvinylacetate, glass fiber powder can reduce UV in glass mixture
The shrinking percentage of solidified resin, and glass fibre then improves the freedom from cracking ability of ink after brushing, to promote the attachment of ink
Ability.
The filler is to be modified to be prepared to kaolin:
The preparation process of the filler includes the following steps:
SS1, kaolin is added in Muffle furnace, in 1000-1100 DEG C of roasting temperature 2-2.5h, after roasting,
Kaolin is taken out into cooling for use, kaolinic crystal structure can be destroyed by carrying out calcination process to kaolin, make kaolinite
The partial size of soil increases, and hardness is promoted, and surface can reduce, so that kaolinic dispersibility be made to get a promotion；
After SS2, the pH to 3.5-4 by inorganic acid adjusting deionized water, silane coupling agent is added thereto, stirs to molten
Liquid clear makes silane coupling agent complete hydrolysis, and wherein the volume ratio of silane coupling agent and deionized water is 1:2-2.5, obtains
To silane coupling agent hydrolyzate, in this step, the silane coupling agent hydrolyzate prepared will be timely used, and prevent polycondensation shadow
Ring the effect of silane coupling agent；
SS3, mass concentration is prepared as the potassium chloride deionized water solution of 0.2%-0.35% and is heated to boiling, press
It takes K-type carragheen to be added in the deionized water solution of the potassium chloride according to parts by weight, adjusts its pH to 7, be cooled to after boiling 10min
After 95-98 DEG C and 8-15min is kept the temperature, wherein the mass ratio of the deionized water solution of carragheen and potassium chloride is 1:15-20；
SS4, the carrageenan solutions for taking previous step to obtain, stirring keep the temperature after being cooled to 70-80 DEG C and adjust speed of agitator
Silane coupling agent hydrolyzate obtained in step SS2 is slowly added into thereto to 300-400r/min, to silane coupled hydrolyzate
After being added completely into, stop stirring and being cooled to rapidly 5-10 DEG C, obtain coagulated colloid structure, wherein carrageenan solutions and silane are even
The volume ratio for joining agent hydrolyzate is 2.5-4:1, and coagulated colloid is ground into uniform small particles, coagulated colloid by mechanical shear stress
The partial size of particle is 2-3mm；
SS5, the kaolin for obtaining step SS1 are added in blender, adjust revolving speed to 300-400r/min, thereto plus
Enter coagulated colloid particle obtained in previous step, after colloidal solid to be solidified is added completely into, promotes revolving speed to 600-800r/
Min continues to stir 5-8min, guarantees that temperature of charge is no more than 10 DEG C in whipping process, ball milling is added in the mixture stirred to get
Modified kaolin is obtained in machine after ball milling 20-50min, wherein ratio of grinding media to material is 2-3.5:1, revolving speed 250-350r/min, kaolinite
The weight ratio of soil and coagulated colloid particle is 10:0.5-2；
SS6, by modified kaolin that previous step obtains 110-120 DEG C at a temperature of baking and curing after crushed 200-
400 meshes obtain filler.
In the method, by the way that silane coupling agent and carragheen are cooperatively formed gel solids, by gel solids obtained
It is dispersed in kaolin after crushing, is easy to appear when to preventing in the prior art using silane coupling agent hydrolyzate
Disperse non-uniform situation, improve the dispersion effect of silane coupling agent, in step SS5, is further promoted by ball milling
Dispersion effect, while passing through the hydrolysis that generated heat when ball milling accelerates carragheen under acidic environment, keep silane coupling agent sudden and violent
Reveal and be coupled with the active group of kaolin surface, is realized to modifying kaolin.
