Aqueous ultra low VOC laser printing transfer printing shaft paint, and preparation method thereof

Abstract

The invention discloses an aqueous ultra low VOC laser printing transfer printing shaft paint, and a preparation method thereof. The aqueous ultra low VOC laser printing transfer printing shaft paintis prepared from, by weight, epoxy resin 40 to 50%, an epoxy resin curing agent 8 to 12%, conductive carbon black 4 to 6%, and deionized water 38 to 42%. According to the conductive paint provided bythe invention, the VOC content of various raw materials are controlled strictly, so that the VOC content of the paint is extremely low, and is lower than 6.2 g / L. A raw material system different fromthe existing formula is adopted, so that the paint is convenient for equipment cleaning, and it is beneficial for environment protection. The paint technology performance is extremely excellent, the dispersibility of conductive carbon black is extremely excellent; the raw material system is subjected to grinding using a basket type sand mill, so that the paint possesses alcohol wiping resistance,paint film damage is not easily caused, fading is not easily caused, and wear resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of conductive coatings, in particular to a water-based ultra-low VOC, alcohol-resistant, wear-resistant and good dispersibility coating for laser printing transfer shafts and a preparation method thereof. Background technique [0002] Printer is an indispensable machine in our daily life, and its use has largely liberated people's hands. Laser printing transfer shafts are an important part of printers. With the increasing popularity of printers, there is an increasing demand for laser printing transfer shafts in the market. According to incomplete statistics, the number of laser printing transfer shafts consumed every year is about billions. The traditional laser printing transfer shaft uses a conductive paint to print, while the prior art uses oily nylon paint. Solvents such as toluene, xylene, and formaldehyde in the oily paint are very harmful to the human body and the environment. At present, there are...
