【摘要】 绿色、可持续发展已成为当今科技的主题,天然环保油墨的研究是印刷领域凸显该主题的重要课题。然而,传统天然颜料大豆油基环保型油墨存在耐温性差的缺点。本文打破了传统天然颜料大豆油基油墨不能用于高温、加热食品及包装印刷的局限。研制实用型耐温天然颜料大豆油基环保油墨具有重要现实意义。本文引入有机硅,并充分利用其Si-O键的键能121千卡/克分子,在高温下(或辐射照射)分子的化学键不断裂、不分解特性实现油墨耐高温性能。实验选用二甲基硅油、甲基三甲氧基硅烷、乙烯基三甲氧基硅烷和氨丙基三乙氧基硅烷试剂作为油墨的耐温试剂,以红色油墨为例,分析不同温度下不同组油墨的色密度、光谱反射率,探究油墨对高温的敏感性,以便提高其实用价值。实验表明,二甲基硅油与大豆油混合时,发生交联反应,生产白色絮状物,影响实验继续进行。随温度的升高,以甲基三甲氧基硅烷、乙烯基三甲氧基硅烷、氨丙基三乙氧基硅烷作为耐温试剂的油墨,初步表现耐温性:油墨的色强、灰度、色效率均在合理范围内变化,油墨的光谱反射曲线波动较小。氨丙基三乙氧基硅烷除可作为耐温试剂外,还具备调色剂的功用。更多还原

【Abstract】 Traditional ink based on natural pigment and soybean oil has disadvantages of poor temperature adaptive in application process.This project broke the limitations that stocks printing with traditional ink based on natural pigment and soybean oil could not be used for heating. Developing practical temperature-resistance environment-friendly ink based on natural pigment and soybean oil is of great importance.The experiment introduced the silicone material,and made full use of its characteristic.The Si-O bond of silicone can be 121kcal/mole,and its molecular bond cannot be broken down at a high temperature(or exposure to radiation).The property of high temperature resistance mainly depends on its unique functional group or long polymer chain structure.The experiment studied temperature resistance environment-friendly ink’s performance in color,in order to improve its practical application value.更多还原
