环保速印乳化油墨的研制

乳化油墨是以油为分散介质,水为分散相的W/O型乳状液,是以较少的油包大量的水,并要有较长的乳化稳定期,具有油性油墨的基本性能和印刷适应性。乳化油墨不仅印刷性能好,而且成本低,含水率高。以水代油有着显著的社会效益,是油墨发展的主要方向。设备和工艺简单、安全,所有的原料均无毒,是完全的绿色产品。     

FS-醇溶性塑料油墨通过技术鉴定

目前我国每年要花大量外汇进口聚酰胺树脂油墨、用于凹版塑料薄膜袋的印刷。这种油墨虽然光亮度好、附着力强、印刷性能好。但目前这种油墨所用的溶剂绝大多数是以有毒害的致癌物质甲苯、二甲苯等苯类为溶剂,在油墨的生产和印刷使用过程中,大量溶剂散发空间。严重污染环境、危害操作工人的身体健康。在国外已逐渐被以水-乙醇为溶剂的无毒油墨所代替。为了开发我国无毒的新型油墨,南宁市科委于1986年5月,下达给南宁市虫胶油墨厂和中国林业科学研究院南京林产化学工业研究所以紫胶为连接料、乙醇为溶剂、无毒的FS-醇溶性塑料油墨的研制任务。南京林产化学工业研究所是科研单位,有较深厚的

Development of mineral oil free offset printing ink using vegetable oil esters

Until the middle of this century, fats and oils are the major raw material source for paints, coating and lubricating applications. These markets are completely taken over by petroleum based stocks due to their abundance and versatility. However, recent public awareness to use environmentally acceptable products that minimize pollution, are compatible to human health and readily biodegradable created opportunities for vegetable oils for application in paints and printing inks. The formulation of vegetable oil methyl ester based 'green' offset printing ink that reduces the volatile organic compounds (VOC) has been discussed in the present study. Methyl esters of rapeseed, soybean, rice bran and palm oil have been prepared and their physical properties have been measured and compared with standard petroleum feed stock. Varnishes were prepared with these esters and their properties are also compared with that of the petroleum based products. Rheological properties of the inks are also evaluated and compared with standard printing ink using petroleum based solvent. In general performance of the ester-based printing inks are comparable with that of the mineral oil based product. On the basis of tack stability and gloss, ester based inks are much superior than the mineral oil based products. In conclusion, a new non-volatile diluent for printing ink has been developed. The diluent is made from common vegetable oils like rapeseed, soybean, rice bran and palm oil, a renewable source that is environmental friendly. Vegetable oil esters offer a cost effective solution for mineral oil based printing ink to meet VOCs regulations.

Development of karanja oil based offset printing ink in comparison with linseed oil

The conventional offset lithographic printing ink is mainly based on linseed oil. But in recent years, due to stiff competition from synthetic substitutes mainly from petroleum products, the crop production shrinks down to an unsustainable level, which increases the price of linseed oil. Though soyabean oil has replaced a major portion of linseed oil, it is also necessary to develop alternate cost effective vegetable oils for printing ink industry. The present study aims to evaluate the performance of karanja oil (Pongamia glabra) as an alternative of linseed oil in the formulation of offset printing ink because karanja oil is easily available in rural India. Physical properties of raw karanja oil are measured and compared with that of alkali refined linseed oil. Rosin modified phenolic resin based varnishes were made with linseed oil as well as with karanja oil and their properties are compared. Sheetfed offset inks of process colour yellow and cyan is chosen to evaluate the effect of karanja oil in ink properties. In conclusion, karanja oil can be accepted as an alternate vegetable oil source with its noticeable effect on print and post print properties with slower drying time on paper. However, the colour and odour of the oil will restrict its usage on offset inks.

Pollution preventing microemulsion inks

Pollution caused by the clean up of lithographic printing presses is a major problem faced by the printing industry. This paper explores alternate ink systems where the use of hydrocarbon solvents and volatile organic compounds (VOCs) for clean up is eliminated. The ink under consideration is a microemulsion, which can be emulsified in plain water-the property that can be used for its cleanup from presses. Furthermore, the washing is a completely physical process with no chemical reaction occurring thereby eliminating any salt streams. The ink washing commences in the form of tiny jets of water-soluble material vigorously coming out at the interface of the microemulsion ink drop and the wash liquid. Spontaneous emulsification is therefore proposed as the mechanism of washing. This paper discusses the ink formulation, its properties, and a model for spontaneous emulsification to explain its washing. The theoretical work is supported by experimental results.

Polyurethane Synthetic Papers Based on Different Inorganic Fillers with Water and Fire Resistance

Polyurethane synthetic papers based on different inorganic fillers are prepared via wet phase inversion process and inorganic mineral filling modification technique. The surface and cross‐section morphology, tensile strength and elongation at break, fire resistance, water and oil adsorption, ink contact angle, writing and printing effects, and water resistance of synthetic paper are investigated, respectively. A large number of pores are present on the surface and in the interior of the synthetic papers and provide huge space for ink molecules. The synthetic paper with transparent powder filled exhibits the optimal performance in tensile strength and elongation at break. Moreover, the fire resistance of polyurethane is improved by inorganic particles, and the highest limit oxygen index value of synthetic paper reaches up to 31.8%, which meets the standard of flame retardant. Meanwhile, filled synthetic papers exhibit high water and oil adsorption capacity, good ink‐affinity, excellent writing and printing effects. In addition, filled synthetic papers perform well in water resistance when written and printed synthetic papers are immersed in water. This work may provide a new idea to design a novel, greener, and multifunctional synthetic paper for its broad applications.

The influence of ink viscosity,water and fabric construction on the quality of ink‐jet printed polyester

This paper is concerned with the quality of lines and disperse ink in printing patterns on different untreated polyester fabric constructions. The lines running in the weft and warp directions were printed on polyester fabric constructions, and printing accuracy was assessed. Ink spreading is one of the important factors that influences the ink distribution. Thus, in order to acquire satisfactory ink‐jet printing products, it is essential to control the spreading of ink on the polyester fabric. To meet these conditions, a series of chemicals (disperse dye 5.01 wt%, PVP‐K30 0‐2 wt%, DEG 5‐20 wt%, water 64.17‐79.17 wt%, etc) with different mass fractions was used to prepare disperse ink. The jetting behaviour of ink was related to its surface tension and viscosity, which was characterised by an automatic surface tensiometer and rotational viscometer. Line profile was used to evaluate the printing effect. Low field nuclear magnetic resonance and three‐dimensional super depth digital microscopy were used to reveal the relationships between the state of water, ink diffusion behaviour and printing sharpness. The results showed that increasing ink viscosity or decreasing free water content is advantageous to improve the sharpness of the printing pattern. The effects of fabric structural parameters on line image quality are discussed. The printing quality was closely related to the weight and structure of fabric. The heavy weight fabrics had accurate print pattern sharpness. The fastness test results showed that the ink printing pattern had good colour fastness.
