Abstract

The invention provides amino drying static varnish. The amino drying static varnish is prepared from the following raw materials in parts by weight: 100-120 parts of polyphenylene sulfide, 30-40 parts of polytetrafluoroethylene, 40-50 parts of polyether-polysulfone, 30-40 parts of lead fluoride, 200-250 parts of water, 20-30 parts of surface active agent and 130-150 parts of propylene glycol. The amino drying static varnish is baked for 45 minutes at the temperature of 370 DEG C, a smooth coating with good adhesive force and high hardness can be formed, and the kinetic friction coefficient is not more than 0.155.

Description

technical field [0001] The invention relates to a method for preparing a coating, in particular to an amino drying electrostatic varnish. Background technique [0002] The current electrostatic varnish has been widely used, but the wear resistance of the electrostatic varnish is not good enough, and the paint film is not hard enough. Contents of the invention [0003] The purpose of the present invention is to provide an amino drying electrostatic varnish to solve one or more problems in the prior art. [0004] According to one aspect of the present invention, an amino drying electrostatic varnish is provided, comprising the following raw materials in parts by weight: 64-68 parts of castor oil alkyd resin, 32-35 parts of melamine formaldehyde resin, 3.6-4 parts of butanol, organic 0.4-0.6 parts of silicone oil, and the mass fraction of organic silicone oil is 1%-2%. [0005] The amino-drying electrostatic varnish provided by the invention comprises mixing melamine-formal...
