Abstract

The invention discloses an acid and alkali resistant metal powder coating and a preparation method thereof. The powder coating comprises the following used materials in parts by mass: 35-45 parts of bisphenol A epoxy resin, 25-35 parts of hydroxy acrylic resin, 15-20 parts of phenolic resin, 2-4 parts of 2-methylimidazole, 9-12 parts of aluminum-silver powder, 2 parts of a sand ripple agent, 16-18 parts of titanium dioxide, 12-14 parts of calcium carbonate, 0.5 part of benzoin and 0.4 part of white carbon black. The prepared powder material has excellent acid and alkali resistance, and due to usage of an automatic feed bonding machine in the preparation process, the obtained powder has high and stable quality.

Description

technical field [0001] The invention belongs to the technical field of powder coatings, in particular to an acid-alkali-resistant metal powder coating and a preparation method thereof. Background technique [0002] Powder coating is a new type of solvent-free, easy-to-operate, 100% solid powdered environmentally friendly coating. Powder coating has high utilization efficiency and is widely used in household appliances, automobiles, construction, petroleum and petrochemical industries. A variety of powder coatings for pigments, it can display a bright, luxurious decorative effect, ideal for spraying indoor and outdoor objects such as furniture, accessories and automobiles. Existing metal powder coatings are usually not resistant to acid and alkali corrosion, and tend to be blackened and damaged after contact with acid or alkali liquids. [0003] Using a bonding machine to bond powder coatings and metal pigments is a relatively good method for preparing metal powder coatings ...
