Abstract

The invention provides a preparation method of antirust durable powder painting for an automobile. The painting is rich in raw material source and low in cost; by virtue of combination of various auxiliary materials and main materials as well as interaction and coordination of all the ingredients, the insulating painting has the characteristics of strong light exposure resistance, ageing resistance, rainwater erosion resistance, skid-proof property and the like, and especially has quite excellent antirust property and endurance quality.

Description

technical field [0001] The invention relates to the field of paint materials, in particular to an antirust and durable powder paint for automobiles, and also to a preparation method thereof. Background technique [0002] Automotive paint has gone through three major leaps in history: alkyd paint in the 1920s; acrylic paint in the 1960s and clear paint in the 1980s. The main characteristics of the performance of automotive paint: good fullness of the paint film, high gloss, high hardness, good adhesion, excellent mechanical properties of the paint film, excellent gloss retention, weather resistance, wear resistance, and good Acid resistance, alkali resistance, alcohol resistance, gasoline resistance. [0003] However, the existing car paints cannot meet the requirements of use, and the antirust effect is poor; in particular, the existing car paints have poor durability, and the phenomenon of discoloration and oxidation after a few years is serious.
