Description
Technical Field
The invention relates to the technical field of fine chemicals, in particular to natural aromatic quick-drying offset printing ink and a preparation method thereof.
Background
As a functional ink for printing fragrance, the fragrance ink mainly comprises a binder, a pigment, an auxiliary agent and a fragrance microcapsule. Wherein, the main components of the ink are esters, alcohols or ketones and aromatic hydrocarbons. The main components of the perfume are alcohols, phenols, ethers, aldehydes, ketones, esters, or the like, and both can coexist in general. In order to maintain the stability and durability of the fragrance, the fragrance is prepared into a microcapsule with fragrance, and then the microcapsule is permeated into the ink for printing. During the use of the fragrant printed matter, the microcapsules are broken by friction and the like, so that the fragrance is released.
At present, the essence has quite complex composition, and most of organic substances contained in the essence are volatile and chemically unstable substances such as alcohol, phenol, ether, aldehyde, ketone or ester. Therefore, the volatile and volatile materials are inevitably volatilized and dissipated or decomposed and deteriorated during the use and the storage. At present, in order to protect essence from the influence of external environmental factors and prolong the fragrance releasing period, the traditional process is to slowly oxidize essence microcapsules after contacting with air to continuously release fragrance, so that the fragrance retaining period is greatly prolonged, and some essence microcapsules can mutually react to generate fragrance substances only under the catalysis of the environmental factors such as ultraviolet rays, sunlight irradiation, oxygen air circulation, heating, humidity change and the like. Although these methods can avoid the volatilization of the perfume, the microencapsulation increases the difficulty of the ink process and increases the production cost, and in addition, most of the perfume uses alcohol, phenol, ether, aldehyde, ketone or ester which are artificially synthesized volatile perfumes, and a large amount of adsorption can generate toxic and side effects. Therefore, the development of natural fragrant quick-drying inks is of great significance.
Disclosure of Invention
In order to solve the problems, the invention provides a preparation method of natural aromatic quick-drying offset printing ink, which comprises the following steps:
(1) cleaning and drying plant petal or leaf, pulverizing with pulverizer, sieving with 60 mesh sieve, placing the sieved powder in extraction kettle of supercritical fluid extraction device, and introducing into CO2Extracting the powder for 1-3h under the conditions of flow rate of 1-4kg/h, temperature of 30-60 ℃ and extraction pressure of 8-20MPa to obtain plant essential oil;
(2) uniformly mixing alkylphenol and formaldehyde, adding a catalyst, carrying out phenolic polymerization reaction for 0.5-2h at the temperature of 140-200 ℃ and the pressure of 0.4-1.0Mpa to obtain an oligomer, uniformly mixing the oligomer, rosin and polyalcohol, and carrying out phenolic modification for 0.5-1h at the temperature of 150-220 ℃ and the pressure of 0.3-1.0Mpa to obtain high-performance resin;
(3) stirring and mixing linseed oil, tung oil and mineral oil, heating to 150-180 ℃, adding high-performance resin, preserving heat for 20-40 min, cooling, adding a gelling agent, heating to 150-180 ℃, preserving heat for 30 min, and adding mineral oil for mixing uniformly to obtain a binder;
(4) uniformly mixing the prepared connecting material, the pigment and the plant essential oil, placing the mixture on a three-roll machine, rolling the mixture for 2 to 3 times under the pressure of 10 to 20MPa and the temperature of 30 to 50 ℃, then reducing the pressure of the three-roll machine to 3 to 6MPa, adding a drier and an antioxidant into the ground printing ink, uniformly mixing the mixture, and adjusting the viscosity to a set range by using mineral oil to obtain the natural aromatic quick-drying type offset printing ink.
Preferably, the plant petals and leaves in the step (1) are one of rose petals, lily petals, eucalyptus globulus leaves, lemongrass and mint; the addition amount of the plant powder is 200-400 g.
Preferably, the molar ratio of the added amount of the alkylphenol to the formaldehyde in the step (2) is 1: 1.5-2.5; the catalyst is a mixed catalyst of sulfonic acid type strong acid and metal sulfate; the addition amount of the catalyst is 0.2-0.5%.
Preferably, the polyol in step (2) is one of ethylene glycol, glycerol and 1, 4-butanediol.
Preferably, the mixing ratio of the linseed oil to the tung oil in the step (3) is 2:1: 0.5; the gel is diethyl aluminum acetate diisopropyl ester or dialkyl aluminum chelate of XP148, and the addition amount of the gel is 0.2-1.0%.
Preferably, the drier in the step (4) is a mixture of manganese isooctanoate and cobalt isooctanoate, and the addition amount of the drier is 1.0-2%.
Preferably, the antioxidant in the step (5) is one of tea polyphenol, citric acid, butyl hydroxy anisole and dibutyl hydroxy toluene, and the addition amount of the antioxidant is 1-2%.
Preferably, the viscosity in the step (5) is 11 to 13 Pa.s.
The natural aromatic quick-drying offset printing ink is prepared by the preparation method.
Compared with the traditional preparation method of the fragrant offset printing ink, the preparation method of the natural fragrant quick-drying offset printing ink has the advantages that natural fragrant components are extracted by adopting a supercritical fluid extraction technology to serve as a flavoring agent of the printing ink, so that the printing ink has natural fragrance, and adverse effects of the added artificial flavoring agent on a human body are avoided; rosin and polyhydric alcohol are used for modifying and modifying resin, so that the adhesion of the printing ink can be obviously improved, and the offset printing efficiency is improved; in addition, a drier is added in the process of preparing the ink, so that the ink can be quickly dried during offset printing, and the printing efficiency is improved.
