Abstract

The invention belongs to the field of multi-functional insulating coatings and discloses a solvent-free polyurethane flame-retardant insulating coating capable of being applied to protection of motors, electric appliances, electric wires and cables as well as a preparation method and an application of the coating. The solvent-free polyurethane flame-retardant insulating coating comprises the components in parts by mass as follows: 50-70 parts of modified ricinic acid polyester polyol, 20-30 parts of a flame retardant, 5-20 parts of abrasion-resisting packing, 1-2 parts of a surfactant, 0.5-1 part of a catalyst and 20-30 parts of an isocyanate curing agent. The insulating coating has the good insulating performance, also has the excellent flame-retardant performance, does not produce volatile organic compounds during usage and is an environment-friendly product.

Description

technical field [0001] The invention belongs to the field of multifunctional insulating coatings, and in particular relates to a solvent-free polyurethane flame-retardant insulating coating which can be used for the protection of motors, electrical appliances and wires and cables, as well as its preparation method and application. Background technique [0002] Paint has a history of thousands of years. It is a multifunctional material that is coated on the surface of objects to protect, decorate, mark and endow special functions.
