Abstract

The invention specifically relates to an antistatic abrasion-resistant UV coating and a preparation method thereof, and belongs to the field of materials. The antistatic abrasion-resistant UV coating comprises the following components in percentage by mass: 5 to 35 percent of multifunctional polyurethane acrylate, 15 to 45 percent of epoxy acrylate, 10 to 40 percent of reactive diluent, 2 to 12 percent of photoinitiator, 0.5 to 3 percent of other additives, 5 to 25 percent of conductive nano-attapulgite powder, and 0.05 to 0.5 percent of silane coupling agent. The coating of the invention has an appearance of white liquid or light yellow liquid; the surface resistance of a coat prepared by the coating of the invention is 4.8*10<6> to 6.5*10 <8> ohms; the 100-revolution weight loss in the Taber abrasion resistance test is 0.0045 to 0.0075 gram; and the surface hardness is more than or equal to 3 H; and the coating does not change after dipping in 5 percent sodium hydroxide for 24 hours. The antistatic abrasion-resistant UV coating of the invention has the advantages of simple preparation, low cost, convenient use, good effect and wide application prospect.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an antistatic and wear-resistant UV coating and a preparation method thereof. Background technique [0002] Antistatic coatings are a group of special functional coatings with volume resistivity within a certain range. Its earliest research record is the conductive adhesive patent published in the United States. Japan has long developed silver-based and carbon-based antistatic coatings, which are used in the electronics industry and military fields. Our research in this area started relatively late, but developed rapidly, especially since the country mandated the use of antistatic coatings for oil tanks in the 1990s, the application of such coatings in oil tanks has developed rapidly. [0003] At the same time, with the development of high technology and the wide application of polymer materials, static electricity problems are also very prominent in some electronic industr...
