The invention discloses a plant straw, recycled plastic and reclaimed rubber composite plate stool surface which is characterized by being prepared from: I, a reclaimed rubber foamed layer which is prepared from the following raw materials in parts by weight: 100 parts of reclaimed rubber, 5-7 parts of a composite foaming agent, 1-2 parts of sulfur, 2-3 parts of zinc oxide, 1-2 parts of stearic acid, 1-2 parts of an accelerant M and 20-50 parts of light calcium, and II, a sythetic-wood foamed layer which is prepared from the following raw materials in parts by weight: 100 parts of recycled polyolefin, 30-50 parts of plant straw powder, 6-8 parts of a composite foaming agent and 10 parts of light calcium. The plant straw, recycled plastic and reclaimed rubber composite plate stool surface has the beneficial effects that the bending resistance of the stool surface is greater than 10Mpa, the tensile strength of the stool surface is greater than 20Mpa, the Shore type A hardness of the reclaimed rubber is 40-50 degrees, and the stool surface has the advantages that the waste is turned into wealthy, the cost is low, the density is relatively small, the heat preservation property is good, the heat is insulated, the external temperature influence is avoided, the surface is flexible, rich in elasticity and comfortable to sit, and the environment can be protected.
