Abstract

The invention discloses a high-temperature resistance methyl phenyl polysiloxane resin powder coating and a preparation method thereof. The coating comprises following components, in parts by weight: 47 to 53 parts of methyl phenyl polysiloxane resin, 0.3 to 0.8 part of tert-butyl peroxide, 8 to 12 parts of methyltris(methylethylketoxime)silane, 1.1 to 1.3 parts of organic silicon levelling agent, 2.5 to 3.0 parts of polysiloxanes, 3.3 to 3.8 parts of triglycidyl isocyanurate, 9 to 10 parts of aluminium nitride powder, 5.5 to 7.5 parts of nano brick slag powder, 1.3 to 1.8 parts of 1-methyl amyl alcohol and 2 to 3 parts of propylene glycol methyl ether acetate. The methyl phenyl polysiloxane resin has the advantages of excellent damp-resistance, waterproofness, stainlessness, cold-resistance, ozone-resistance and weatherability. The methyl phenyl polysiloxane resin has a good high-temperature resistance performance, and the heat-resistance temperature arrives at 550 DEG C or more.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a high-temperature-resistant methylphenyl polysiloxane resin powder coating 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 pron...
