A preparation method of an antistatic one-component polyurethane coating including polyurethane oligomer 3651100, furnace carbon black 5, titanate coupling agent 0.1, dimethyl ethanolamine 0.6, the proportion of xylene, cyclohexanone and butyl acetate is 4 to 1 to 2, and mixed solvent 50. The carbon black is dried in 80 DEG C, sprayed with the coupling agent, and ball-milled for 90 minutes. Then the carbon black, the resin and the solvent are serially added into the container and at the same time stirred to form a preliminary mixing product, which is then poured into a ball-milling tank to be ball-milled for 90 minutes. Then the coating is filtered and stood still to get the finished product. The invention has the following advantages of simple preparation method, convenient operation, reduced cost, good antistatic performance, and no damage of intrinsic mechanical performance and other performances of the product.
Description
technical field [0001] The invention belongs to a method for preparing an antistatic one-component polyurethane paint. Background technique [0002] At present, the manufacturing method of products with antistatic properties is to use antistatic plastics for injection molding and molding. Antistatic plastics are expensive, with reduced performance, high cost and long cycle; antistatic performance is unstable. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of preparation method of antistatic one-component polyurethane coating. [0004] The technical solution of the present invention is: a preparation method of antistatic one-component polyurethane coating, characterized in that: polyurethane oligomer 3651 100, furnace carbon black 5, titanate coupling agent 0.1, dimethylethanolamine 0.6, Xylene: cyclohexanone: butyl acetate=4: 1: 2 mixed solvent 50, after carbon black is dried at 80 ℃, carbo...
