Description
Technical field
The present invention relates to offset printing fountain solution technical field, be specifically related to a kind of compounding containing kappa-carrageenan-Konjac glucomannan
Anticorrosive mildewproof fountain solution and preparation method thereof.
Background technology
Offset printing is to utilize the two natural law that profit is the most miscible, solid is to the selective absorption of liquid,
The picture and text replicated and blank parts are set up jointly at the unified plate surface through technical finesse, makes blank parts have very
Strong water absorbing properties, areas oleophylic water repellent.In printing process, first whole forme is supplied water, make the blank parts of the space of a whole page
Adsorb water and form water membrane, subsequently, then give forme ink supply.Now, owing to forme blank parts has existed water membrane,
Ink can not adsorb in blank parts, areas water repellent oleophylic and adsorb one layer of ink.Therefore, fountain solution work in offset printing
With very important.
Non-ionic surface active fountain solution is the novel fountain solution grown up in recent years, is to use nonionic surfactant
Replace the low surface tension fountain solution of ethanol, it is to avoid the alcohol steam produced after isopropanol volatilization in traditional water dampening system, by
Low in nonionic surfactant surface tension, wettability good, can reduce the consumption of fountain solution, becomes high speed multicolour offset press
In preferable fountain solution.Therefore, research new non-ionic fountain solution has great significance to improving printing quality.
Kappa-carrageenan (κ-carrageenan) is by the natural sea algin extracted in red algae, has heat-convertible gel, resists
Albumen condenses and the hydrophilic characteristic such as nontoxic, also has formation hydrophilic colloid, gel, thickening, emulsifying, film forming, stable dispersion etc. excellent
Optimum energy, is widely used in food industry, daily chemical industry and the field such as biochemistry, medical research, thus carrageenan industry is rapidly
Development.The gel that kappa-carrageenan is formed has that desired concn is low, transparency advantages of higher, but exist gel fragility big, elastic little,
The problems such as easy syneresis, can solve these problems by the synergistic function with other foodstuff glues.Research shows,
After adding other polysaccharide in kappa-carrageenan, even non-gelled polysaccharide, its gelling properties also can be greatly improved.According to
The reports such as Phillips etc. and Williams, after carrageenan mixes with locust bean gum, it is elastic, strength and stability has significantly
Raising；Adding xanthan gum can make carrageenan more soft, more flexible and viscosity increase；Gelatin and the cogelled system of carrageenan
In, storage modulus increases along with carrageenan concentrations and increases, and it is cogelled with carrageenan that low concentration sodium chloride is conducive to improving gelatin
Matter structure.
Wei Yu, Wang Yuanlan, Hu Yunchu et al. report a kappa-carrageenan and Konjac glucomannan compound gel rheological property and
Study on Microstructure, the impact on compound gel rheological behavior such as examination shear rate, frequency of vibration and temperature.In Kappa-Carraginan
Add a certain amount of Konjac glucomannan (konjac gum), owing to Konjac glucomannan has higher retentiveness and stickiness, can be filled into smoothly
In the ordered network structure that kappa-carrageenan is formed, defined by intermolecular hydrogen bonding based on kappa-carrageenan network structure, evil spirit
Taro glue interts cross-linked network system therein, can form the resilient heat-convertible gel of tool, and the gel formed has required former
Material less, the feature such as big, the good springiness of gel strength.Compound gel preparation fountain solution hence with kappa-carrageenan with Konjac glucomannan has very
Big Research Prospects.
