Abstract

The invention discloses insulating waterborne type aluminum paste which is characterized by consisting of the following raw materials in parts by weight: 40-60 parts of micron-size flake aluminum, 2-4 parts of mica powder, 1-2 parts of shell powder, 0.5-1 part of gypsum powder, 10-12 parts of tetraethyl orthosilicate, 0.01-0.02 part of sodium molybdate, 0.1-0.2 part of sodium hydroxymethylglycinate, 0.1-0.2 part of aluminum dihydrogen phosphate, 0.2-0.4 part of silane coupling agent A-151, 4-6 parts of poly-dimethyl diallyl ammonium chloride, 0.1-0.2 part of castor oil phosphate, 6-8 parts of carboxymethyl cellulose, 1-2 parts of glycerol and 8-10 parts of auxiliary agent. The aluminum paste disclosed by the invention has good electrical insulating property, anti-aging property, water dispersity and coating adhesion, and is suitable for using places with relatively high insulation requirements.

Description

technical field [0001] The invention relates to the field of metal pigments, in particular to an insulating water-based aluminum-silver paste and a preparation method thereof. Background technique [0002] Aluminum silver paste is mainly composed of aluminum powder, solvent and additives. After special processing technology and surface treatment of pigments, the surface of aluminum flakes is smooth and smooth, and it has excellent compatibility with coating systems. It has excellent light reflection ability and metallic luster. The paint film has "Different color effect with angle", the decorative effect is beautiful. [0003] With the development of industrialization and the deterioration of the environment, protecting the environment has become a common issue for all mankind. Traditional solvent-based aluminum silver paste contains a large amount of VOC (volatile organic compounds), which volatilize into the atmosphere during the coating process and cause pollution to the...
