【摘要】：烟用内衬纸作为卷烟行业的一种包装材料,主要分为复合铝箔纸与真空镀铝纸两大类;其主要功能是起到保香、保润、遮光等阻隔作用,同时也完美展示材质的美观性。鉴于复合材料的缺陷,归类为:(1)在纸基金属复合过程中,复合铝箔纸残留有害溶剂,如:粘合剂、着色剂及添加剂等;在去溶剂过程中,干燥系统需要消耗较多能源。(2)在生产中,真空镀铝纸具有能耗高、经济性差以及铝层过薄增加了印品的报废率等缺点,并对运输与存储具有严格要求。因此,本文以凹印的方式为基础,提出基于水性金属油墨及其在纸张表面改性的研究构思,将研究内容归纳如下:首先,对目前烟用内包装材料的现状进行市场调研,结合现有烟用内衬纸生产工艺,综合阐述了纸基金属复合材料和水性油墨的发展现状,明确了存在的问题和发展趋势,指出了研究水性金属油墨及其纸张表面改性的必要性和可行性。其次,在对水性金属油墨各组成部分的理论分析基础上,结合目前在油墨配方中最常用的原材料,通过各原材料性能分析和对比的方法,选择了水性金属油墨配方中的各组成部分的原材料,之后参考金属油墨配方专利确定了各成份的用量,提出水性金属油墨配方,并根据提出的配方制备出了水性金属油墨样品。该配方所选原材料均符合绿色环保的要求。再者,本文以制备的水性金属油墨样品为试验材料,通过调试印刷压力、印刷速度和改变试验辊参数等方法,得到了水性金属油墨在纸张涂覆的样品,并对试验样品的重金属、可挥发性化合物、色差、含水量等性能指标进行了检测和结果分析。通过对试验样品性能的检测可知,用该水性金属油墨配方生产的印刷样品与压延复合铝箔纸在色差、厚度、克重等指标上还有一定差距,但该产品在重金属和可挥发性化合物等指标上均满足食品级包装材料的要求。
[Abstract]:As a kind of packaging material in cigarette industry, cigarette liner paper is mainly divided into two categories: compound aluminum foil and vacuum aluminized paper. Its main function is to protect fragrance, moisturize and shade, and at the same time, to show the beauty of material perfectly. In view of the defects of the composite materials, they can be classified as: (1) in the process of paper-based metal composite, the residual harmful solvents such as adhesives, colorants and additives are retained in the composite aluminum foil paper; In the process of solvent removal, the drying system needs to consume more energy. (2) in production, vacuum aluminized paper has the disadvantages of high energy consumption, poor economy and too thin aluminum layer, which increases the scrap rate of printed matter, and has strict requirements for transportation and storage. Therefore, on the basis of gravure printing, this paper puts forward the research conception of water-based metal ink and its modification on paper surface. The research contents are summarized as follows: firstly, market research on the present situation of tobacco inner packaging materials is carried out. Combined with the existing production process of cigarette lined paper, the development status of paper matrix metal composite material and water-based ink was comprehensively expounded, and the existing problems and development trend were clarified. The necessity and feasibility of surface modification of waterborne metal ink and its paper are pointed out. Secondly, on the basis of the theoretical analysis of the components of water-based metal ink, combining with the most commonly used raw materials in ink formulation at present, through the method of performance analysis and comparison of each raw material, The raw materials of each component in the formulation of water-borne metal ink were selected, and then the dosage of each component was determined by referring to the patent of the formula of metal ink, the formula of water-borne metal ink was put forward, and the sample of water-borne metal ink was prepared according to the formula. The raw materials selected by this formula are in line with the requirements of environmental protection. Furthermore, by adjusting printing pressure, printing speed and changing the parameters of the test roll, the waterborne metal ink coated on the paper is obtained, and the heavy metals of the test sample are obtained by using the waterborne metal ink sample as the experimental material. Volatile compounds, color aberration and water content were tested and analyzed. By testing the performance of the test sample, we can see that there is still a certain gap between the printing sample produced by the waterborne metal ink formula and the calendered composite aluminum foil in terms of color difference, thickness, gram weight, etc. However, the product can meet the requirements of food-grade packaging materials in heavy metals and volatile compounds.
