Acrylate modified hydroxyl-terminated butadiene resin with low infrared emissivity, and preparation method thereof

The invention discloses an acrylate modified hydroxyl-terminated butadiene resin with low infrared emissivity, and a preparation method thereof. The acrylate modified hydroxyl-terminated butadiene resin is obtained through free radical copolymerization of hydroxyl-terminated polybutadiene and an acrylate monomer and/or a methacrylate monomer, and the solid content of the obtained acrylate modified hydroxyl-terminated butadiene resin with low infrared emissivity is 40-60wt%. The acrylate modified hydroxyl-terminated butadiene resin with low infrared emissivity has the advantages of low glossiness and good weather ability, can be used to prepare dual-component infrared camouflage coatings, and can be used to coat military use devices, machines, engineering, barracks and other places to realize a camouflage purpose.
