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

[0029] An insulating varnish The insulating varnish is prepared from the following raw materials by weight: 40 parts of unsaturated polyester imide resin, 15 parts of polyester modified epoxy resin, 8 parts of phthalate, maleic 11 parts of dianhydride, 6 parts of phthalates, 3 parts of dimethicone, 1 part of clay gelling agent, 2 parts of modified polysiloxane, 4 parts of glycidyl ether oxypropyl trimethoxysilane, 5 parts of a mixture of polyvinyl butyral, light calcium carbonate and cyclomethicone, 3 parts of a curing agent, and 4 parts of a 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, and has good toughness, which can increase the mechanical strength of insulating paint; phthalate is soluble in most organic solutions, low...

Embodiment 2

[0031] An insulating varnish prepared from the following raw materials in parts by weight: 40 parts of unsaturated polyester imide resin, 15 parts of polyester modified epoxy resin, 10 parts of phthalate, cis-butyl 16 parts of enedioic anhydride, 5 parts of dimethicone, 4 parts of clay gelling agent, 6 parts of modified polysiloxane, 5 parts of glycidyl ether oxypropyl trimethoxysilane, polyvinyl butyral, light 5 parts of the mixture of calcium carbonate and cyclomethicone, 4 parts of diethylenetriamine, 6 parts of the mixture of melamine formaldehyde resin and polydimethylsiloxane, wherein, melamine formaldehyde resin and polydimethylsiloxane Mixed at 3:7, after many experimental verifications, it has been shown that although melamine formaldehyde resin has good hardness, wear resistance and electrical insulation performance, it is easy to cause the adhesive layer to break easily after the paint is cured, so it should not be used alone and should be used with other fluids. Mi...

[0033] An insulating varnish The insulating varnish is prepared from the following raw materials in parts by weight: 35 parts of unsaturated polyester imide resin, 10 parts of polyester modified epoxy resin, 8 parts of phthalate, maleic acid 13 parts of acid anhydride, 4 parts of dimethicone, 2 parts of clay gelling agent, 5 parts of modified polysiloxane, 4 parts of glycidyl ether oxypropyl trimethoxysilane, polyvinyl butyral, light calcium carbonate and 4 parts of the mixture of cyclomethylsiloxane, 4 parts of polyether polyester modified organosiloxane, 2 parts of ketimine curing agent, the ketimine curing agent is composed of 3-methyl-2-butane Ketone and 1,3-diaminomethylcyclohexane are prepared by Schiff reaction. Although the ketone imine type can cure epoxy resin at room temperature, the lone pair of electrons on the imine nitrogen atom still has a certain amount of The ring-opening activity of 3-methyl-2-butanone and the highly active diamine 1,3-diaminomethylcyclohexa...

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 paint suitable for power distribution cabinets, in particular to an insulating paint and a preparation method thereof. Background technique [0002] At present, 80% of the power distribution cabinets on the market are made of cold-rolled steel plates. The power distribution cabinets of this type of material are reliable in quality and cheap in price, and are widely used. 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 formulation and processing technology, the performance of various insulating coatings is also uneven. In practical applications, the mechanical strength, insulating properties and breakdown resistance of insulating coatings are good. It plays a key role in the economic and technical indicators and operating li...
