Abstract

The invention discloses an electrical insulating packaging material and a preparation method thereof. The electrical insulating packaging material is mainly prepared from a carrier material, adhesive resin and organic silicon resin, wherein the carrier material is prepared from the following raw materials in parts by weight: 25-50 parts of epoxy resin, 15-35 parts of phenolic resin, 12-30 parts of PVC (polyvinyl chloride); 8-25 parts of weather-resistant acrylic resin; the adhesive resin is melamino-formaldehyde resin or melamine urea-formaldehyde resin suitable for being impregnated, wherein the solid content of the resin is 35-55%; the organic silicon resin is prepared from the following raw materials in parts by weight: 15-40 parts of methyl triethoxysilane, 12-30 parts of diethoxydimethylsilane, 8-25 parts of silicon carbide and 25-55 parts of an organic solvent. The packaging material disclosed by the invention has a good electric insulating property and good weather resistance, and the curing property of the epoxy resin is improved.

Description

technical field [0001] The invention relates to the field of packaging materials and production methods thereof, in particular to an electrical insulating packaging material and a preparation method thereof. Background technique [0002] Epoxy resin is a kind of thermosetting polymer material with good adhesion, electrical insulation and chemical stability. As a resin matrix for adhesives, coatings and composite materials, it is widely used in construction, machinery, electronics, electrical, aerospace and other fields. When epoxy resin is used, a curing agent must be added, and the curing reaction is carried out under certain conditions to form a three-dimensional network structure product, which will show various excellent properties and become an epoxy material with real practical value. Therefore, the curing agent is indispensable in the application of epoxy resin, and even plays a decisive role to some extent. [0003] At present, the research on latent curing agents ...
