Problems solved by technology

However, during the use of insulating varnishes formulated with such active monomers (such as Axalta's Voltatex series products and Von Roll's Damisol-3630, etc.), due to their low volatility, the viscosity of the varnishes at high temperatures drops rapidly, and the insulating The varnish is seriously lost during the baking process, which leads to a small amount of varnish hanging on the motor after dipping the insulat

Abstract

The invention discloses an environmentally-friendly high-paint-hanging-amount pure resin impregnated insulating paint and a preparation method thereof. The environmentally-friendly high-paint-hanging-amount pure resin impregnated insulating paint comprises 97.89-99 wt% of imine-modified low-viscosity self-crosslinkable unsaturated polyester resin, 0.9-2 wt% of dicumyl peroxide, 0.01-0.1 wt% of cobalt naphthenate and 0.05-0.2% of hydroquinone. The imine-modified low-viscosity self-crosslinkable unsaturated polyester resin is prepared from maleic anhydride, saturated binary acid, polyhydric alcohol, modified monofunctional imine alcohol, methyl methacrylate modified hydroxyl diphenyl ether, tetrabutyl titanate and hydroquinone. No micromolecular active monomer is added into the product, andan imine structure and a diphenyl ether structure are introduced into the resin, so that the heat resistance, the mechanical properties and the electrical insulation property of the resin can be obviously improved, and the product has the advantage of high paint hanging amount, and avoiding of smoking during high-temperature baking.

Description

technical field [0001] The invention relates to the technical field of insulating varnish, in particular to a pure resin-impregnated insulating varnish with high hanging paint volume and an environment-friendly insulating varnish and a preparation method thereof. Background technique [0002] Vacuum pressure impregnation (VPI for short) technology has been widely used in the insulation technology of electric motors and electrical appliances at home and abroad. VPI technology includes many elements, but the insulation performance mainly depends on the VPI impregnated resin. Most of the VPI impregnating resins used at home and abroad use styrene as diluent. [0003] Styrene has strong reactivity, good compatibility with resin, high solid content of insulating varnish, uniform and full paint film after baking; styrene has low viscosity, therefore, the viscosity of insulating varnish with high solid content is small, and the permeability of insulating varnish Good, easy to rea...
