preparation example 1

[0043] This preparation example discloses a preparation method of a microcapsule phase change material (MCPCM), including:

[0044] S01, get n-tetradecane 200kg and methyl methacrylate 100kg and mix both; Add styrene maleic anhydride copolymer 12.5kg to the mixture of n-tetradecane and methyl methacrylate and mix evenly; Under ultrasonic vibration (frequency 60kHz), add 600 kg of water to the mixture of the above three (n-tetradecane, methyl methacrylate and styrene maleic anhydride copolymer), and control the addition time for 30 minutes; after that, ultrasonic vibration 2h, water is mixed with n-tetradecane, methyl methacrylate and styrene maleic anhydride copolymer to obtain an emulsion;

[0045] Among them, n-tetradecane is a low-temperature solid-liquid phase change material, and is used as a core material of the microcapsule; methyl methacrylate is a wall material monomer of the microcapsule; and styrene-maleic anhydride copolymer is used as an emulsifier.

Abstract

The invention relates to the field of printing ink, and particularly discloses a printing ink, and a preparation method and application thereof. The printing ink is prepared from, by weight, 100 parts of polyurethane resin, 106 to 120 parts of pigment, 75 to 85 parts of methyl 3-methoxypropionate, 135 to 145 parts of ethyl 3-ethoxypropionate, 25 to 35 parts of n-propyl acetate, 85 to 95 parts of ethanol, 6 to 12 parts of n-propyl alcohol and 7 to 10 parts of a first dispersing agent. The preparation method of the printing ink comprises the following steps: weighing the above raw materials, dissolving the resin, mixing for the first time, grinding, mixing for the second time and the like. The printing ink is printed on the surface of a packaging bag. By using the organic solvent with good environmental protection property, the damage of the organic solvent in the ink to a human body can be reduced, and the pollution of the organic solvent to the environment is also reduced, so that the environmental protection property of the ink is improved. Meanwhile, the printing ink disclosed by the invention has good adhesive force, surface dryness, normal-temperature viscosity and color, so that the ink has good working performance.

Description

technical field [0001] The application relates to the field of ink, more specifically, it relates to an ink and its preparation method and application. Background technique [0002] Ink is an important material for printing, which is a viscous colloidal fluid mainly composed of binders, pigments, solvents and additives. Among them, the binder acts as a medium for dispersing the pigment, and after ink printing, the binder can form a film layer with a certain strength to protect the pigment; the binder is usually a resin, such as polyurethane resin, polyacrylic resin, epoxy resin, etc. . Pigments are color-developing components that can impart various colors to inks. The solvent is the carrier of each component of the ink, including organic solvents and water; according to different solvents, inks can be divided into oil-based inks and water-based inks. Auxiliaries include leveling agents, matting agents, wear-resistant agents, etc., which can give ink more performance. ...
