Abstract
The present invention refers to a chromium-free insulation coating material for non-oriented silicon steel, comprising, in parts by weight, the following components: metal dihydrogen phosphate salt of 100 parts, epoxy resin of 10˜60 parts, naphthenate drier or isooctanoate metal salt drier of 0.001˜10 parts, organic solvent of 0.001˜100 parts and pure water of 60˜2000 parts. The metal dihydrogen phosphate salt is Al(HPO), Mg(HPO), Ca(HPO)or Zn(HPO); the epoxy resin is water-soluble epoxy resin or epoxy resin emulsion. Chromium-free insulation coating material of the present invention, after being coated on non-oriented silicon steel, renders highly transparent appearance, and has excellent insulativity, corrosion resistance, adhesiveness, weldability and manufacturability, so as to eliminate defects of the existing chromium-free coating, such as sticky and un-wear-resistant and to meet environment protection requirements.
