Insulating layer material, stainless steel based copper clad plate, surface treatment method and preparation method

Abstract

The invention discloses an insulating layer material, a stainless steel based copper clad plate, a surface treatment method and a preparation method. The insulating layer material with high thermal conductivity comprises components in parts by mass as follows: 80-120 parts of epoxy resin, 1-50 parts of a curing agent, 0.05-5 parts of a curing accelerator, 1-40 parts of an additive, 1-500 parts of hyperpure filler with high thermal conductivity and 1-50 parts of an organic solvent. The prepared stainless steel based copper clad plate with high thermal conductivity has the following advantages: 1, the stainless steel based copper clad plate has high thermal conductivity and is superior to like products in the market; 2, the insulation property is good, the puncture resistant voltage can be up to or higher than 6KV; 3, the insulating layer with high thermal conductivity is combined with the stainless steel base well, and the layered plate blasting phenomenon is avoided during heat shock; 4, the mechanical processing property is good, and the layered cracking phenomenon of a medium layer is avoided; 5, the production efficiency is high; 6, the cost is low and is about one second of commercially available products.
