Problems solved by technology

[0002] At present, a large number of ordinary lighting panels on the market are usually made of glass fiber reinforced composite materials. Although they have high light transmittance, their transparency is also very high. When used as lighting materials, infrared rays and ultraviolet rays will directly irradiate indoors. , not only cause high indoor temperature, but also cause damage to human skin, especially in hot summer, when the temperature and ultraviolet intensity are high, the temperature in workshops and workshops rises, and cooling appliances such as air conditioners or fans need to be turned on indoors, consuming A large amount of electric energy, in addition, the flame retardancy of the existing daylighting board is not enough, so we propose an improved daylighting board and its preparation method

Abstract

The invention relates to the technical field of daylighting panels, and discloses an improved daylighting panel and a preparation method thereof. The improved daylighting panel comprises a PET lower film, a fiber reinforced composite material, a gel coat layer and a solar film, wherein the fiber reinforced composite material comprises the following raw materials: 50%-60% of unsaturated polyester resin; 18%-30% of reinforced glass fiber; 0.8%-2.0% of a flame retardant; 0.8%-2.5% of an antioxidant; 1.0%-2.5% of a curing agent; 0.5%-2.0% of an accelerant; 0.1%-8% of an infrared blocking agent; and 0.1%-8% of an ultraviolet blocking agent; wherein the sum of the components is 100%. The invention also provides a preparation method of the improved daylighting panel, the daylighting panel prepared by the method can effectively block the transmission of infrared rays and ultraviolet rays on the premise of meeting the mechanical property requirements and daylighting requirements of the daylighting panel, and meanwhile, the daylighting panel prepared by the method also has relatively strong flame retardant property and corrosion resistance and is very suitable for popularization and application.
