Abstract

The invention provides green and pollution-free environment-friendly aluminum paste. The green and pollution-free environment-friendly aluminum paste comprises, by weight, 100-150 parts of aluminum powder, 125-150 parts of solvent oil, 0.5-0.7 part of stearic acid, 0.2-0.4 part of coupling agents and 1-2 parts of auxiliaries. The green and pollution-free environment-friendly aluminum paste has theadvantages that the green and pollution-free environment-friendly aluminum paste can be safely used and is free of toxic and harmful effects on human bodies; the green and pollution-free environment-friendly aluminum paste can be used with diversified basic materials and accordingly is extensive in application; films are durable, and good protection effects can be realized; processes for producing the green and pollution-free environment-friendly aluminum paste are simple and are low in cost.

Description

technical field [0001] The invention relates to a green and pollution-free environment-friendly aluminum powder slurry. Background technique [0002] Aluminum powder paste is also called aluminum-silver paste. Aluminum-silver paste pigment is an important and indispensable metal pigment in modern industrial products. Its characteristics are that the surface of aluminum flakes is smooth and flat, the particle size distribution is concentrated, the shape is regular, and it has excellent light reflection ability and metallic luster. It can be used alone in paints, inks, and plastics to produce silver metallic effects; it can also be used with other pigments. , to produce a metallic effect in different colors such as gold. Aluminum-silver paste pigments can be evenly arranged in parallel for up to 12 layers in general protective coatings, and the sheets are sealed by the base material. The coating film structure can shield the substrate from external gas, moisture, light, etc. ...
