Abstract

The invention discloses an organic / inorganic hybrid transparent heat-insulating coating material. The coating material comprises the following raw materials by mass: 45 to 85 parts of a UV light-cured resin, 5 to 50 parts of a nanometer heat-insulating particle dispersion liquid and 1 to 4 parts of an auxiliary agent. The invention also discloses a preparation method for the coating material. The preparation method comprises the following steps: (1) preparation of the nanometer heat-insulating particle dispersion liquid; (2) preparation of a nanometer modified sol; (3) preparation of the organic / inorganic hybrid UV-cured resin; and (4) preparation of the hybrid transparent heat-insulating coating material: a step of preparing the raw materials according to above-mentioned mass proportions, adding the raw materials into a reaction vessel and carrying out high speed dispersion so as to obtain the coating material. The invention further discloses application of the coating material. The coating material is applicable to heat insulation and protection in the aspects of energy-saving electric light sources, photoelectric materials, energy-saving windows, solar cells, etc. According to the invention, through addition of a functional heat-insulating particle into an organic / inorganic hybrid resin system, an obtained transparent heat-insulating coating has high visible light transmittance and a substantial effect on obstruction of infrared and near infrared heat radiation.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an organic / inorganic hybrid transparent heat-insulating coating material for the surface of a polymer substrate, a preparation method and an application thereof; Good adhesion and visible light transmittance, obvious blocking effect on infrared and near-infrared photothermal radiation; Background technique [0002] Heat insulation coating is a functional coating with heat insulation, sun protection, energy saving and environmental protection. Infrared heat reflective coating is an earlier application of heat insulation coating. It has high reflectivity and high emissivity. By selectively reflecting infrared radiation, it prevents heat transfer from the source, inhibits heat deposition, and reduces exposure to solar heat radiation. The surface temperature of the lower equipment and the internal ambient temperature. So as to achieve the effect of thermal ins...
