Abstract

The invention relates to an ultraviolet photo-cured coating for the electrostatic prevention of the surface of plastic and a preparation method thereof, in particular to a photo-cured coating containing conductive powder of a metal oxide system or composite conductive powder. The coating comprises the following compositions in weight percent: 30 to 70 percent of oligomer, 25 to 65 percent of active thinner, 0.5 to 10 percent of light evocating agent, 5 to 40 percent of conductive powder, 0.2 to 8 percent of additive and 0 to 50 percent of solvent. As the added conductive powder of the metal oxide system and the composite conductive powder is white or light color, the prepared photo-cured has the characteristic of easy color modulation, has lasting antistatic property, high rigidity and wearing resistance, can be used for electrostatic prevention of the surface of electronic equipment, plastic vessel, shell of an electric appliance, office supplies, sports equipment and other plastic products.

Description

technical field [0001] The invention relates to an ultraviolet curable coating for antistatic plastic surface and a preparation method thereof, which is characterized in that the photocurable coating is prepared by using metal oxide conductive powder or composite conductive powder, which has antistatic durability, adjustable color, and is very durable. High hardness and wear resistance and other characteristics. Background technique [0002] Plastic has the characteristics of light weight, good design flexibility, low price and durability. It is increasingly used in industrial production and daily life instead of metal or wood materials. However, it is a good choice due to its high surface resistance and low dielectric constant. Insulators are prone to static electricity due to friction or impact, resulting in the accumulation of a large amount of static electricity on the plastic surface, which can easily cause surface dust collection, affect the appearance quality of the p...
