Abstract

The invention discloses waterborne type aluminium paste for leather coating, which is characterized by consisting of the following raw materials in parts by weight: 40 to 60 parts of micron-sized leafing aluminium powder, 1 to 2 parts of sea-foam stone powder, 1 to 2 parts of zeolite powder, 10 to 12 parts of ethyl orthosilicate, 0.01 to 0.02 parts of ethylene glycol diglycidyl ether, 0.05 to 0.1 parts of melamine, 0.01 to 0.02 parts of sodium diethylhexyl sulfosuccinate, 0.2 to 0.4 parts of silane coupling agent A-151, 0.05 to 0.1 parts of disodium polyepoxysuccinicate, 4 to 6 parts of poly dimethyl diallyl ammonium chloride, 6 to 8 parts of carboxymethylcellulose, 0.1 to 0.2 parts of zinc borate and 8 to 10 parts of an assistant. The aluminium paste disclosed by the invention has excellent covering power and metallic texture, has a certain light resistance, heat resistance and tarnishing resistance, has good dispersibility in a waterborne coating system, enables the coating to have a high adhesion property and a leveling property and be firm, has certain air permeability and is suitable for the leather coating.

Description

technical field [0001] The invention relates to the field of metal pigments, in particular to a water-based aluminum-silver paste for leather coating 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 pollutio...
