Abstract
The invention relates to the research of long-afterglow luminous printing ink, mainly aiming to decrease the production cost of the luminous printing ink and improve the functions of the printing ink. The invention emphasizes the functions and the environmental protection of the printing ink product and the improvement of the luminous afterglow time of the printing ink and the wettability and the drying speed of paper.
Description
Technical field
The development of long-afterglow luminous printing ink belongs to chemical field.
Background technology
China has about 300,000 tons of the comprehensive annual capacity of printing-ink at present.Printing ink output accounts for 6% of world's printing ink ultimate production, has become the world the fourth-largest printing ink producing country, is only second to the U.S., Japan, Germany.The printing ink that is applied to digital printed industry at present mainly contains three kinds of water color ink, solvent type ink and UV curing inkss, and three kinds of printing ink respectively have superiority.Wherein solvent type ink is because cheap, and the user is numerous and occupy the maximum market share.
At the individual digital printing market, using maximum at present is laser printing technology.Though laser printer is many with respect to the confidential costliness of spray ink Printing,, seriously restricted the popularization of spray ink Printing at individual printing market because the cost of printing ink is higher and factor such as not environmental protection.Spray ink Printing is mainly used in commercialization printing markets such as wide cut at present.Under the Scientific Outlook on Development that current country establishes and the condition of carrying out the strategy of sustainable development, developing low-cost, environment-friendly type printing ink are the main directions of present figure punch development.
Summary of the invention
1, the preparation method of long after glow luminous material
The character of long after glow luminous material is not only relevant with composition, the structure of material, and the form that exists of material also has very significant effects to its luminescent properties.So at first will obtain to have the powder luminous material of excellent luminescent properties, in the preparation process of printing ink, not destroy the structure of luminescent material as far as possible.High temperature solid-state method is the traditional synthetic method of luminescent material, and this method is convenient to large-scale production.So the synthetic method of this project mainly based on high temperature solid-state method, is explored chemical precipitation method simultaneously, the material preparation method that hydrothermal method etc. are new.
Key in the sintering process is the control of temperature and atmosphere, usually generation and the distribution that the control by sintering atmosphere can the control material defective.Sintering is beneficial to and produces the oxygen room in material in the reducing atmosphere, thereby the effect that the electronics of excited state reaches the luminous twilight sunset of prolongation material can be caught in the oxygen room.Final stage can attempt adding various fusing assistants to improve the sintering character of material under the prerequisite that does not influence the material luminescent properties, reduce sintering temperature, reduces the production cost of material.

2+Content can prolong time of persistence.By changing the composition structure of silico-aluminate matrix, exploitation is based on Mn
2+The long after glow luminous material of silico-aluminate is to reduce the preparation cost of luminous printing ink.Weak action face promoting agents such as luminescent powder selection stearic acid are carried out finishing to luminescent powder.
3, the functional modification of water-based emulsion
Phosphoric acid ester is the important tensio-active agent of a class, and phosphoric acid ester is anionic emulsifier efficiently in letex polymerization.Utilize different types of phosphoric acid ester (alkyl phosphate, aliphatic alcohol polyoxyvinethene phosphate, alkylol amide phosphoric acid ester etc.) that emulsion is carried out functionalized modification, transfer the pH value of system with ammoniacal liquor.
4, the preparation of water-based long-afterglow luminous printing ink
Digital printed water color ink structurally is oil-in-water-type; Utilize suitable tensio-active agent to carry out finishing pigment, long-persistence luminous body, then it is scattered in the water-based emulsion behind the functionalized modification.Water-based emulsion belongs to penetration drying type ink, therefore keep reducing the water content of water color ink under water color ink stability of emulsion and the mobile prerequisite as far as possible, improves the solid content of printing ink, to improve water color ink rate of drying on paper.Water is formed pure water, water-retaining agent, water-holding agent (antidesiccant, wetting Agent for Printing Inks, antifreezing agent) and Antisepticize and mildew preventive.
The maximum difference of water-based long-afterglow luminous printing ink and other water color ink is that long after glow luminous material and colo(u)rant dispersion be the main tensio-active agent that relies in water.There is weak interaction between tensio-active agent and long afterglow luminescent powder material surface, the size of powder granule, the type of weak effect and the strong and weak persistent quality that all might influence powder.Therefore in printing ink preparation and use, do not destroy the original structure of luminescent powder as far as possible.
Based on aqueous polyurethane, aqueous epoxy resins and vinylformic acid, be that dispersion agent prepares the water-based long-afterglow luminous printing ink respectively with water.To the use properties of resulting printing ink, parameters such as flowability, drying property and long-persistence luminous performance characterize, and determine preferred embodiment.
