Abstract

The invention relates to a long-acting antistatic coating as well as an application and a product thereof. The long-acting antistatic coating comprises the following components in parts by mass: 5-30 parts of a hydrophilic photosensitive resin, 5 to 30 parts of a water-soluble active monomer; 0.01 to 1 part of nano ceramic powder; 0.05 to 3 parts of an antistatic agent; 0.5 to 5 parts of a photoinitiator; 45 to 90 parts of water; and 0.5 to 6.3 parts of an auxiliary agent. The inventor specially selects the nano ceramic powder to be applied to preparation of the long-acting antistatic coating and cooperates with other components, the hardness of a coating formed by the long-acting antistatic coating is improved, the antistatic performance requirement is met, water is adopted as a solvent, and the prepared long-acting antistatic coating is a water-based coating, so that the long-acting antistatic property of the long-acting antistatic coating is improved. The method has the characteristics of environmental friendliness, ultralow VOCs content, high safety and the like.

Description

technical field [0001] The invention relates to the technical field of material chemistry, in particular to a long-acting antistatic coating and its application and products. Background technique [0002] Due to their good processability and electrical insulation properties, polymer materials and products are widely used in 3C electronics, integrated circuits, communications, household appliances, lens windows, and precision equipment manufacturing. However, due to the high surface resistivity of polymer materials and products (>10 14 Ω / cm 2 ), it is easy to accumulate static electricity during use, resulting in electrostatic dust collection, reducing the manufacturing yield of electronic products, and even causing adverse consequences such as fire and explosion. In the ANSI / ESD S20.20:2007 standard, the hazards and protection requirements of electrostatic discharge (ESD) are clearly stated. [0003] Antistatic treatment of polymer materials is generally divided into t...
