Powder coating containing modified tree ash and preparation method of powder coating

Abstract

The invention discloses a powder coating containing modified tree ash and a preparation method of the powder coating. The powder coating consists of the following raw materials: modified epoxy resin, low-density polyethylene resin, phenolic resin, modified tree ash, organosilicone leveling agent, film-forming resin, polydimethylsiloxane, aliphatic amine, silver powder, acrylic resin, ultra-fine calcium carbonate, hexamethylenetetramine, catechol and simethicone. The powder coating is a green and environmental-friendly coating, has no toxicity, has high-temperature resistance, contains no solvent and has no VOC (Volatile Organic Compounds) emission; and furthermore, the modified tree ash is added in the powder coating, so that the compatibility of the modified epoxy resin, the low-density polyethylene resin and the phenolic resin is enhanced, the surface leveling of the powder coating is improved, the powder coating has the advantage of high gloss retention and the decorative property of the powder coating is enhanced; and the qualified rate of the finished product obtained by preparing is high and the industrial mass production can be realized.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a powder coating containing modified tree ash and a preparation method thereof. Background technique [0002] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the powder coating business of metal components is also increasing, especially in industries such as household appliances, instruments and meters, transportation facilities, aluminum profiles, various vehicles, and daily hardware. , powder coating can provide metal with excellent anti-corrosion protection and decorative properties, but due to the unsatisfactory anti-pollution performance of existing coatings used in the above-mentioned fields, various types of dust, dirt and even oil are often attached to the coating; anti-sticking ability It is also not ideal, and the coating formed by the existing powder coating is prone to blistering, cracking, pee...

[0002] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the powder coating business of metal components is also increasing, especially in industries such as household appliances, instruments and meters, transportation facilities, aluminum profiles, various vehicles, and daily hardware. , powder coating can provide metal with excellent anti-corrosion protection and decorative properties, but due to the unsatisfactory anti-pollution performance of existing coatings used in the above-mentioned fields, various types of dust, dirt and even oil are often attached to the coating; anti-sticking ability It is not ideal, and the coating formed by the existing powder coating is prone to blistering, cracking, peeling and other phenomena under the influence of natural conditions such as outdoor long-term exposure to the sun and rain. Therefore, the mechanical properties of the coating are not ideal
