The invention discloses a high-weather-resistance gel coat and a preparation method thereof. The high-weather-resistance gel coat comprises the following raw materials by mass: 70-80% of unsaturated polyester resin, 1-3% of fumed silica M5, 10%-20% of titanium dioxide, 0.3%-0.7% of defoamer, 0.3%-0.7% of a leveling agent, 0.3%-0.7% of an antioxidant, 0.3%-0.7% of an ultraviolet absorber, 0.8%-1.2%of wax powder PA and 3%-5% of nanometer silicon oxide, summing to 100%. According to the high-weather-resistance gel coat, the weather resistance, the temperature resistance and the like of the gel coat are effectively improved; meanwhile, the mechanical property of the high-weather-resistance gel coat is improved; and preparation is simple, and cost is low.
Description
technical field [0001] The invention relates to a high weather-resistant gel coat and a preparation method thereof, belonging to the field of gel coats. Background technique [0002] Gel coat resin is a special resin, which is a special resin for making the gel coat layer of FRP products. It mainly plays the role of protecting FRP products, prolonging its service life and decorating its surface. It is crucial to the quality of FRP products. influences. [0003] With the rapid development of the FRP industry, the requirements for the quality, appearance and surface gel coat of FRP products are constantly increasing. Although the existing gel coats have improved mechanical properties and corrosion resistance to a certain extent, their weather resistance and temperature resistance are poor, and discoloration and cracking will occur after long-term use, continuous use at high or low temperatures. Contents of the invention [0004] The invention provides a high weather resist...
