Super heat insulation coating loaded with nano titanium dioxide and preparation method of super heat insulation coating

Abstract

The invention discloses a super heat insulation coating loaded with nano titanium dioxide. The super heat insulation coating is prepared from the following raw materials in parts by weight: 38-42 parts of ethyl orthosilicate, an appropriate amount of ethanol and deionized water, 0.1-0.2 part of maleic anhydride, 0.7-0.9 part of hexamethyldisilazane, 0.4-0.5 part of 3-aminopropyl triethoxysilane, 0.4-0.5 part of nano titanium oxide, 70-75 parts of E-12 epoxy resin, 9-12 parts of ethylene glycol diglycid ether and 7-7.5 parts of triethanolamine. The coating disclosed by the invention uses silicon dioxide aerogel and has a super heat insulation property; by loading nano titanium dioxide to the aerogel, the ageing process of the aerogel is retarded, and the service life of the aerogel is prolonged; and by using hexamethyldisilazane to perform modification, the hydrophilic property of the aerogel is improved, and the phenomenon that the aerogel is broken up and degraded by absorbing water is reduced.

AI Technical Summary

Benefits of technology

This patented technology describes how an oxidized layer can be added onto certain materials like ceramic or metal for better heat retention without losing their effectiveness over time due to damage caused during use. Silicon Aerogels have excellent properties such as high specific surface area (BSA) that makes them ideal candidates for this purpose. They also provide good water repelling characteristics with reduced air permeability compared to traditional methods used for creation of porous structures. Overall, these technical improvements make it possible to improve durability while maintaining its ability to effectively absorb infrared light waves.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the mechanical property (strength) of an organopolymer called polytreegum oxide that contains tiny holes or cracks made through chemical reactions during manufacturing processes like synthesis. Current methods involve modifying the surfaces of these particles without changing their functionality, leading to weakened structures even if they were reinforced afterwards. To address this issue, there have been attempts at adding various types of functional agents onto the modified particle surface before mixing them into resin systems.
