Composite material for producing shower pan

The invention in particular relates to a composite material for producing a shower pan and belongs to the technical field of sanitary ware manufacturing. The material comprises the following various materials in percentage: 30-45% of 200-mesh ground limestone, 10-15% of 300-mesh ground limestone, 14-20% of 100-mesh quartz sand, 14-20% of 200-mesh quartz sand, 10-24% of an unsaturated polyester resin, 7.9928% of pigment paste, 0.001-0.0024% of an accelerant and 0.0024-0.0048% of a curing agent. According to the composite material disclosed by the invention, the quartz sand and ground limestoneserve as the main fillers, the oil absorption rate of the quartz sand is extremely low, the oil absorption rate of the calcium carbonate is relatively high, the mixture of the two fillers has excellent complementary property, and the produced product is high in mechanical strength and does not layer or crack; due to the season change, the viscosity of the resin is changed at a normal temperature,the fillers of different p
