Abstract

The invention discloses a preparation method of environmental-friendly type pressure-sensitive oil for carbonless copying paper. The preparation method comprises the following steps: 1) pretreatment: compounding and heating solvent oil, and stirring uniformly; 2) dissolution: heating and dissolving colorless dye and the solvent oil to obtain a color forming agent; 3) pre-emulsification: adding and mixing an emulsifying agent, a wall material and deionized water into the color forming agent in the step 2) to obtain emulsified liquid; 4) emulsification: shearing and emulsifying at a high speed to the particle diameter needed by capsules, so as obtain emulsified liquid; 5) curing: carrying out curing on the emulsified liquid in the step 4) to form microcapsules; 6) hardening: carrying out water-bath insulation on the microcapsules in the step 5); 7) oil formation: adding an adhesive and an isolating agent into the microcapsules in the step 6) to obtain the pressure-sensitive oil. The environmental-friendly type pressure-sensitive oil for the carbonless copying paper, prepared by the preparation method, is non-toxic and non-irritating, is good in safety and wide in application range and is environmental-friendly and pollution-free.

Description

technical field [0001] The invention relates to a preparation method of carbon paper pressure-sensitive oil, in particular to an environment-friendly preparation method of carbon-free carbon paper pressure-sensitive oil. Background technique [0002] Carbon-free copy paper is mainly used for multi-part forms, bills, continuous financial notes, general business financial notes, etc. It has been widely used in people's work and life. The principle is to make the force-sensitive pigment in the microcapsules And the oil solution overflows, and after contacting with the color developer, a dyeing reaction occurs, thus playing the role of copying. [0003] With the continuous development of carbonless copy paper technology, people have higher and higher requirements for carbonless paper pressure-sensitive oil, not only require better performance, but also have requirements in terms of environmental protection, especially in Japan, Europe and the United States and other markets, peo...
