Elastic wind and sand-resistant weather-proof and temperature change-resistant coating and preparation method thereof

The invention discloses elastic wind and sand-resistant weather-proof and temperature change-resistant coating and a preparation method thereof. The elastic wind and sand-resistant weather-proof and temperature change-resistant coating is prepared from the following raw materials of saturated polyester resin, hydroxy acrylic resin, elastic toughened resin, phase change paraffin microcapsules, titanium dioxide, silica powder, polyvinyl alcohol, aluminium silicate fiber, an uvioresistant additive, a wetting dispersant and a curing agent. According to the elastic wind and sand-resistant weather-proof and temperature change-resistant coating, the saturated polyester resin and the hydroxy acrylic resin are used as basic materials, by performing the cross-linking reaction between the two, a reticulate three-dimensional structure can be formed, so as to enhance the performance of the coating such as elasticity, weather resistance, high and low temperature deforming resistance and adhesive force; furthermore, the thr
