This invention relates to the field of polymer composite materials technology, and discloses a material and manufacturing process for resistance to damage and staining. The manufacturing process includes: weighing unsaturated polyester resin, aluminum hydroxide and / or magnesium hydroxide, quartz powder and / or calcium carbonate, organically modified montmorillonite, ammonium polyphosphate crystal form II, and anhydrous calcium borate according to the formula, mixing them to form a homogeneous slurry, then casting it into a gel mold, and finally curing and demolding it to obtain the product.
