Abstract

The invention relates to a high temperature 900-1200 deg.C resistant organic silicion-ceramic coating, using organic silicon resin as base material, mixing with high temperature-resistant pigment, metal oxide and silicate fillings as well as solvent to make it, converting the organic type to the inorganic type at high temperature by paint films so as to implement the high temperature protection of basal bodies. It combines two techniques of organic silicon coating and inorganic high temperature resistant coating to give play to their advantages and avoid their disadvantages, supplementing mutually, further obtaining the convenient-coated normal temperature-hardening high-temperature 900-1200 deg.C-resistant organic-inorganic coating. It has the characters of simple coating process, excellent coating properties, good high temperature resistance, excellent high-temperature anticracking property, ability of recycling, etc.

Description

Technical field: [0001] The invention relates to an organosilicon-ceramic coating resistant to high temperatures of 900-1200°C. It is an organic-inorganic high-temperature-resistant coating that is easy to apply and can be cured at room temperature. Suitable for steel and other metal substrates, components, and equipment used at high temperatures, such as high-temperature furnaces, high-temperature steam pipes, engines, exhaust pipes, heat exchangers, missile launchers, etc. The invention belongs to the field of paint preparation. Background technique: [0002] As stated in Chapter 3, Section 1 of "Special Coatings" published by Chemical Industry Press and Chinese Patent CN1295102A "Organosilicon High Temperature Resistant Coatings", with the development of aviation and aerospace, the important role of high temperature resistant coatings has attracted attention from all over the world. focus on. There are many kinds of high temperature resistant coatings, among which sili...
