Problems solved by technology

[0002] At present, 80% of the distribution cabinets on the market are made of cold-rolled steel plates. The distribution cabinets of this type of material are reliable in quality and cheap, and are widely used. However, this type of distribution cabinet is used in Static electricity is often generated during the process. In order to ensure personal safety, it is necessary to spray antistatic insulating paint on the surface of the power distribution cabinet.

Embodiment 1

[0030] An insulating varnish. The insulating varnish is prepared from the following raw materials in parts by weight: 40 parts of unsaturated polyesterimide resin, 15 parts of polyester modified epoxy resin, 8 parts of phthalate, maleic acid ester 11 parts of dianhydride, 6 parts of phthalate, 3 parts of simethicone, 1 part of clay gelling agent, 2 parts of modified polysiloxane, 4 parts of glycidyl etheroxypropyl trimethoxysilane, 5 parts of mixture of polyvinyl butyral, light calcium carbonate and cyclomethicone, 3 parts of curing agent, 4 parts of leveling agent. Unsaturated polyesterimide resin has good heat resistance, radiation resistance, stable storage, fast curing at low temperature, and can meet the requirements of insulation. Polyester modified epoxy resin has low viscosity, high functionality, no chain entanglement and good solubility, has good toughness, and can increase the mechanical strength of insulating paint; phthalates are soluble in most organic solutions,...

Embodiment 2

[0032] An insulating varnish, the insulating varnish is prepared from the following raw materials in parts by weight: 40 parts of unsaturated polyesterimide resin, 15 parts of polyester modified epoxy resin, 10 parts of phthalate, 16 parts of dimethic anhydride, 5 parts of dimethyl silicone oil, 4 parts of clay gelling agent, 6 parts of modified polysiloxane, 5 parts of glycidyl etheroxypropyl trimethoxysilane, polyvinyl butyral, light 5 parts of mixture of calcium carbonate and cyclomethicone, 4 parts of diethylenetriamine, 6 parts of mixture of melamine formaldehyde resin and polydimethylsiloxane, among which, melamine formaldehyde resin and polydimethylsiloxane It is mixed at a ratio of 3:7. After many experiments and verifications, it has been shown that although melamine formaldehyde resin has good hardness, wear resistance and electrical insulation properties, it is easy to cause the adhesive layer to break after the paint is cured, so it should not be used alone. It shou...

Embodiment 3

[0034] An insulating varnish. The insulating varnish is prepared from the following raw materials in parts by weight: 35 parts of unsaturated polyesterimide resin, 10 parts of polyester modified epoxy resin, 8 parts of phthalate, 13 parts of acid anhydride, 4 parts of dimethyl silicone oil, 2 parts of clay gelling agent, 5 parts of modified polysiloxane, 4 parts of glycidyl etheroxypropyl trimethoxysilane, polyvinyl butyral, light calcium carbonate and 4 parts of mixture of cyclomethicone, 4 parts of polyether polyester modified organosiloxane, 2 parts of ketimine curing agent, the ketimine curing agent consists of 3-methyl-2-butyl Ketone and 1,3-diaminomethylcyclohexane are prepared by Schiff reaction. Although the ketimine type can cure the epoxy resin at room temperature, the lone pair of electrons on the nitrogen atom of the imine still has a certain The ring-opening activity of the insulating varnish is not fast, so the present invention uses the ketone 3-methyl-2-butanon...

Abstract

The invention discloses an insulated paint. The insulated paint is prepared from the following raw materials in parts by weight: 30 to 40 parts of unsaturated polyesterimide resin, 8 to 15 parts of polyester modified epoxy resin, 6 to 10 parts of phthalates, 11 to 16 parts of maleic anhydride, 2 to 5 parts of dimethicone, 1 to 4 parts of clay gel, 2 to 6 parts of modified polysiloxane, 2 to 5 parts of glycidoxy propyl trimethoxy silane, 1 to 5 parts of a mixture of polyvinyl butyral, light calcium carbonate and cyclomethicone, 2 to 4 parts of a curing agent and 2 to 6 parts of a leveling agent. The insulated paint disclosed by the invention has the beneficial effects of simple preparation process, low requirement on preparation equipment, high adhesive force, high mechanical strength, excellent electrical insulating property and high safety; the insulated paint takes polyesterimide resin as a main material and can be suitable for various power distribution cabinets.

Description

technical field [0001] The invention mainly relates to an insulating varnish suitable for a power distribution cabinet, in particular to an insulating varnish and a preparation method thereof. Background technique [0002] At present, 80% of the distribution cabinets on the market are made of cold-rolled steel plates. The distribution cabinets of this type of material are reliable in quality and cheap, and are widely used. However, this type of distribution cabinet is used in Static electricity is often generated during the process. In order to ensure personal safety, it is necessary to spray antistatic insulating paint on the surface of the power distribution cabinet. In the current industry, there are many kinds of insulating coatings. Due to the difference in formula and processing technology, the performance of each insulating coating is also uneven. In practical applications, the mechanical strength, insulation performance and breakdown resistance of insulating coatings...
