Abstract

The invention provides titanium-polymerized polyester-modified organic silicon high-temperature-resistant paint. The paint is prepared from, by weight, 40-60 parts of polyester-modified organic silicon resin, 10-30 parts of solvent, 0.1-2 parts of titanium polymers, 0.5-15 parts of pigments, 5-25 parts of filler, 0.5-2 parts of levelling agent, 1-3 parts of anti-sticking auxiliary and 0.1-5 parts of silver pearl powder. Compared with the prior art, the paint has the advantages of being low in curing temperature, high in curing crosslinking degree, excellent in adhesive force between a coating and a substrate and long in coating service life, is high-quality, durable and healthy paint and can be widely applied to kitchen ware products such as a cake plate, a non-stick pan, an electric baking pan and a bread maker.

Description

technical field [0001] The invention relates to the technical field of high-temperature-resistant coatings, in particular to a titanium-polymerized polyester-modified silicone high-temperature-resistant coating and a preparation method thereof. Background technique [0002] In the 21st century, people pay more and more attention to the improvement of the quality of life, especially in home cooking, people increasingly hope to have high-quality, healthy and environmentally friendly kitchen utensils. At present, polyester-modified silicone coatings, which are widely used in non-stick cookware, have good non-stick properties and are very popular in home kitchens. However, the curing temperature of the coating is as high as 280°C, the bonding force with the substrate is relatively poor, the MEK resistance is average, and the water resistance is insufficient, resulting in a short service life of the coating. Contents of the invention [0003] In view of the problems existing i...
