Description
Technical field
The present invention relates to offset printing fountain solution technical field, be specifically related to a kind of humectant fountain solution compounding containing kappa-carrageenan-konjac glucomannan 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, blank parts is made to have the strongest water absorbing properties, areas oleophylic water repellent.In printing process, first whole forme is supplied water, make the blank parts absorption water of the space of a whole page 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 effect in offset printing is very important.
Non-ionic surface active fountain solution is the novel fountain solution grown up in recent years, it it is the low surface tension fountain solution replacing alcohol with nonionic surfactant, avoid the alcohol steam produced after isopropanol volatilization in traditional water dampening system, owing to nonionic surfactant surface tension is low, wettability is good, the consumption of fountain solution can be reduced, become preferable fountain solution in high speed multicolour offset press.Therefore, research new non-ionic fountain solution has great significance to improving printing quality.
Kappa-carrageenan (κ-carrageenan) is by the natural sea phycocolloid extracted in red algae, have heat-convertible gel, anti-albumen condenses and the hydrophilic characteristic such as nontoxic, also there is the premium properties such as formation hydrophilic colloid, gel, thickening, emulsification, film forming, stable dispersion, it is widely used in food industry, daily chemical industry and the field such as biochemistry, medical research, thus carragheen industrial boom.The gel that kappa-carrageenan is formed has that desired concn is low, transparency advantages of higher, but there is the problems such as big, elastic little, the easy syneresis of gel fragility, 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 Phillips etc. and Williams etc., after carragheen mixes with locust bean gum, its elasticity, strength and stability increase significantly；Adding xanthans can make carragheen more soft, more flexible and viscosity increase；Gelatin is with the cogelled system of carragheen, and storage modulus increases along with carrageenan concentrations and increases, and low concentration sodium chloride is conducive to improving gelatin and carragheen cogelled matter structure.
Wei Yu, Wang Yuanlan, Hu Yunchu et al. report a kappa-carrageenan and the rheological property of konjac glucomannan compound gel and Study on Microstructure thereof, the impact on compound gel rheological behavior such as examination shear rate, vibration frequency and temperature.A certain amount of konjac glucomannan (konjac gum) is added in Kappa-Carraginan, owing to konjac glucomannan has higher retentiveness and stickiness, can be filled into smoothly in the ordered network structure that kappa-carrageenan is formed, define based on kappa-carrageenan network structure by intermolecular hydrogen bonding, konjac glucomannan interts cross-linked network system therein, can form the resilient heat-convertible gel of tool, the gel formed has the features such as needed raw material is few, gel strength big, good springiness.Compound gel preparation fountain solution hence with kappa-carrageenan with konjac glucomannan has the biggest Research Prospects.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of humectant fountain solution compounding containing kappa-carrageenan-konjac glucomannan and preparation method thereof, in order to solve the environmental problem that in now widely used alcohol edition-0 moistening liquid, alcohol and isopropanol volatilization cause.
