The invention provides a UV-resistant BMC material for outdoor use, including resin, aluminum hydroxide, calcium carbonate, curing agent, glass fiber, and anti-UV agent; the resin is an unsaturated resin and a low-shrinkage resin; the The anti-UV agent is benzoic acid or benzotriazole. The invention also provides a manufacturing method of the ultraviolet-resistant BMC material for outdoor use. According to the analysis, comparison and screening test of the existing anti-UV agents, benzoic acid or benzotriazole anti-UV agents are added to the existing common BMC materials, so that the compatibility with the unsaturated resin is good, and the Coloring without affecting material properties and molding. The product has high-efficiency light stabilization effect, non-toxic, non-flammable, non-explosive, non-corrosive, and good storage characteristics. |
