The invention discloses a high-reflection energy-saving roller shutter fabric and a preparation method thereof. The roller shutter fabric is prepared from, by weight, 20-25 parts of gaseous aluminum,15-20 parts of aluminum powder, 10-16 parts of a water-borne acrylate emulsion, 7-12 parts of a glass fiber fabric, 10-19 parts of a polyester fabric, 6-10 parts of silk, 1-7 parts of jute, 3-8 partsof sisal hemp, 1-5 parts of manila hemp, 2-9 parts of a wool fabric, 10-13 parts of modal, 7-11 parts of an inflaming retarding fabric and 4-9 parts of a chemical fiber fabric. According to the high-reflection energy-saving roller shutter fabric, by adding the glass fiber fabric, the polyester fabric, the silk, the jute, the sisal hemp and the manila hemp, the light transmittance of the roller shutter fabric is effectively reduced, the sun shading effect of the roller shutter fabric is improved, by adding the chemical fiber fabric, the functions, such as watertightness, fire prevention, staticresistance, ultraviolet light resistance, breathability and water permeability, of the roller shutter fabric are improved, and by adding polyester fibers, the roller shutter fabric is high in intensity and elasticity recovery capacity. The roller shutter fabric is high in preparation efficiency, simple in preparation method, convenient to use and low in cost.
