AI Technical Summary

Technical Problem

Existing hydrophobic and oleophobic coating materials exhibit performance degradation at high temperatures, and their fluorinated compounds are harmful to the environment and human health, failing to meet the requirements of high-temperature equipment.

Method used

A coating composition consisting of silicates, inorganic fillers, high-temperature resistant inorganic silicon carbon resin, inorganic silicon resin, polybutadiene, high-temperature resistant and corrosion-resistant resin, silane coupling agent and catalyst is used to form a high-temperature resistant hydrophobic and oleophobic coating through the superposition of a base coat and a top coat, ensuring that it maintains hydrophobic, oleophobic and easy-to-clean properties in high-temperature environments.

Benefits of technology

It can maintain its hydrophobic, oleophobic and easy-to-clean properties even after working continuously at high temperatures for more than 2 hours, meeting food contact requirements. It is environmentally friendly and non-toxic, and suitable for high-temperature ovens, microwave ovens and other equipment.

Abstract

The application discloses a high-temperature-resistant hydrophobic and oleophobic coating composition, a high-temperature-resistant hydrophobic and oleophobic coating and a preparation method and application thereof. The high-temperature-resistant hydrophobic and oleophobic coating composition comprises 2.4-3.6 parts by weight of silicate, 2.4-3.6 parts by weight of inorganic filler, 6.4-9.6 parts by weight of high-temperature-resistant inorganic silicon-carbon resin, 5.6-8.4 parts by weight of inorganic silicon resin, 1.6-2.4 parts by weight of polybutadiene, 4.8-7.2 parts by weight of high-temperature-resistant corrosion-resistant resin, 1.6-2.4 parts by weight of silane coupling agent, 24-36 parts by weight of catalyst and 18.5-27.5 parts by weight of solvent. The coating formed by the coating composition of the application can keep the hydrophobic and oleophobic performance and the non-stick / easy-to-clean performance for a long time in a high-temperature environment. The coating formed by the coating composition is environment-friendly and non-toxic, and meets the food contact requirement (food grade).
