Study on Preparation of SnO₂ Polyacrylate Thermal Insulation Film with Liquid Phase Precipitation Process

Abstract:

In the modern world, the theme of low carbon economic development trend advocates energy conservation and discharge reduction, and the energy-saving technology of thermal insulation film of automobile glass and construction glass has attracted increasing more attention. This paper adopts liquid phase precipitation process to prepare nanoSnO₂ polyacrylate thermal insulation organic film: first, select precursor solution concentration in favor of generating outphase precipitation and pH value to prepare SnCl₄ solution with low concentration 2 mM-10 mM, and hydrochloric acid with concentration 0.1 M-0.4 M; select methyl methacrylate 34.5%-90%, BA 10%-35.5%, MAA 0%-30% and AIBN 0.1%-0.3% to prepare polyacrylate film; put the prepared PA film in SnCl solution, control reaction temperature to be 40°C-80°C, maintain reaction time 6-18h, take out the film, wash and dry to get nanoSnO₂ organic thermal insulation film. According to XRD analysis and SEM observation, SnO₂ is uniformly deposited on the surface of organic film, having good thermal insulation performance.
