Abstract

The invention discloses a textile coating with a radiation refrigeration function and a preparation method of the textile coating, and the textile coating is prepared by coating paint with the radiation refrigeration function. Comprising 20.5%-39.85% of water-based acrylic resin, 30.04%-47.15% of reflective pigment filler, 0.23%-0.43% of a dispersing agent, 0.09%-0.15% of a wetting agent, 0.25%-0.52% of a defoaming agent, 0.27%-0.56% of a thickening agent, 0.37%-0.72% of a coalescing agent and 26.99%-37.99% of water, the elongation at break of the water-based acrylic resin is 400%-850%, the reflective pigment filler comprises first filler and second filler, and the second filler comprises the first filler and the second filler. The particle size of the second filler is larger than that of the first filler, the mass ratio of the first filler to the second filler is 6.5: 1-1: 3, the textile coating adopts a one-step coating method to form a functional layer on the surface of the textile material, the reflectivity of the functional layer in visible light and infrared light is larger than or equal to 85%, and the emissivity of the functional layer in the wave band of 7-14 microns is larger than or equal to 85%. The textile coating disclosed by the invention has good radiation refrigeration function and cooling effect, and also has the advantages of simple preparation method and process, soft surface, folding resistance and the like.

Description

technical field [0001] The invention relates to a functional coating, in particular to a textile coating with radiation cooling function and a preparation method thereof. Background technique [0002] Radiation refrigeration technology, as a new passive refrigeration technology with zero energy consumption and zero pollution, has broad application prospects and is in line with the national green development concept. By coating the radiant cooling paint on the surface of the textile, it can inhibit the heat transfer on the surface of the fabric, reduce the temperature inside the fabric covering, and play the role of energy saving and heat insulation. [0003] However, in order to achieve a better radiative cooling effect, the existing textile radiative cooling functional layer needs to be superimposed with multiple layers of paint, resulting in thicker thickness, poor flexibility of textiles, and easy cracking of the paint, which limits its application. In addition, due to ra...
