Abstract

The invention relates to the technical field of preparation of high-whiteness flashing metallic paint. The invention further discloses a preparation method of the high-whiteness flashing metallic paint. Polyamide wax and EVA wax are reasonably added into low-hydroxyl acrylic resin according to a weight ratio, and the preparation method comprises the following steps of: preparing flashing paste, namely aluminum paste, mixing low-hydroxyl acrylic resin into the aluminum paste, and adding polyamide wax and EVA wax into the low-hydroxyl acrylic resin; preparing the leveling agent, and adding cellulose acetate butyrate into the leveling agent; selecting a diluent, which is one of butyl acetate or xylene; and sequentially mixing all the mixed reagents according to a weight ratio. According to the preparation method of the high-whiteness flashing metallic paint, the polyamide wax and the EVA wax are reasonably added into the low-hydroxyl acrylic resin according to the weight ratio, so that arrangement of aluminum paste in the flashing metallic paint can be effectively assisted, the requirement for improving whiteness is met, the excellent anti-settling performance can be improved, and thestorage life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of high-whiteness glitter metallic paint, in particular to a preparation method of high-whiteness glitter metallic paint. Background technique [0002] Automotive metallic paint, also known as automotive metal flash paint, commonly known as silver powder paint; it is a popular car baking paint, with fine aluminum particles added to its paint base. After the light hits the aluminum particles, it is passed through by the aluminum particles The air film is reflected; therefore, it looks as if the metal is shining. This kind of metallic flash paint gives people a pleasant, light and novel feeling of painting color, so it is very common now, changing the shape and size of aluminum particles, Just can control the sparkle degree of metal glitter paint film; Outside metallic paint, also add a layer of varnish to protect. [0003] At present, the market has higher and higher whiteness requirements for flash metallic...
