Abstract

The invention relates to nanofiller modified solvent-free insulating paint and a preparation method thereof, belonging to the technical field of insulating paint. The preparation method is characterized by comprising the following steps: by taking a nano powdery filler as a modifier, filling the modifier into heat-resistant unsaturated polyester resin; adding an active diluent, a peroxide initiator and an auxiliary; and mixing the materials evenly to obtain the nanofiller modified solvent-free insulating paint. The method solves the problems of dispersibility and stability of nanopowder in the insulating paint. The nanofiller modified solvent-free insulating paint is applied to motor insulating treatment and has the advantages of environmental protection and no solvent, high paint hanging quantity, low loss, good insulation property, high heat resistance, long storage period, quick curing and the like. The nanofiller modified solvent-free insulating paint comprises the following components by weight percent: 50-70% of heat-resistant unsaturated polyester resin, 20-50% of diluent, 2-10% of nanofiller, 1-2% of initiator and 0.2-2% of auxiliary.

Description

technical field [0001] The invention belongs to the technical field of insulation, and in particular relates to a nano-material modified solvent-free insulating varnish. Background technique [0002] Due to their unique surface effect, small size effect and macroscopic quantum tunneling effect, inorganic nanoparticles have special mechanical, thermal, electrical and optical properties, and are widely used in various fields of materials. Studies have shown that adding some inorganic nano-fillers to insulating materials can improve the heat resistance and electrical properties of materials, but the dispersion and stability of nanoparticles in insulating materials are the relationship factors that determine the nano-advantages of materials. [0003] Unsaturated polyester solvent-free insulating varnish is mainly composed of diols, saturated dibasic acids and unsaturated dibasic acids after polymerization, and diluted with styrene, diallyl phthalate or acrylate. It has low visc...
