A kind of powder coating of oil-resistant bisphenol A type polycarbonate and preparation method thereof

Abstract

The invention discloses an oil-resistance bisphenol A type polycarbonate powder coating and a preparation method thereof. The coating comprises following raw materials in parts by weight: 48 to 55 parts of bisphenol A type polycarbonate, 1.5 to 2.0 parts of rosin resin, 12 to 15 parts of 4,4- diaminodiphenyl-methane, 0.8 to 1.2 parts of tributyl phosphate, 3.3 to 3.8 parts of amino propyl triethoxysilane, 15 to 25 parts of superfine barium sulfate, 6.0 to 8.0 parts of polyacrylamide, 1.1 to 1.3 parts of diethylenetriamine, and 25 to 30 parts of ceramic slag powder. The method, through adding ceramic slag powder as the stuffing material, greatly improves the waterproof ability of the powder coating. At the same time, through mixing rosin resin, 4,4- diaminodiphenyl-methane, tributyl phosphate, amino propyl triethoxysilane, superfine barium sulfate, and ceramic slag powder together, the dispersibility and compatibility of the raw materials are improved, thus coating property of the powder coating is improved and the film formed is smooth.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a powder coating of oil-resistant bisphenol A polycarbonate 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, cra...

[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
