Stain-resistant artificial quartz stone and manufacturing method thereof

The invention is suitable for the field of building decoration, and provides a stain-resistant artificial quartz stone and a manufacturing method thereof. The stain-resistant artificial quartz stone is prepared from the following raw materials: 44 to 66 parts of quartz sand powder, 12 to 20 parts of modified diatomite, 10 to 20 parts of unsaturated polyester resin, 2 to 8 parts of modified nano silicon dioxide, 1 to 2 parts of pigment, 1 to 2 parts of curing agent, 1 to 3 parts of coupling agent, 2 to 3 parts of accelerant, 1 to 2 parts of antifreezing agent and 1 to 2 parts of stain-resistant agent. The stain-resistant artificial quartz stone provided by the embodiment of the invention is simple in preparation method and high in structural strength, has relatively strong stain resistance, is not easy to deform, blister, fade, lose gloss and the like, also has the characteristics of strong crack resistance, low production cost and good decorative effect, is an ideal plate for industrial and civil buildings, a
