Abstract
The invention discloses a shock-absorbing, wear-resisting and antibacterial rubber floor mat and a preparation method thereof, wherein the rubber floor mat is formed by laminating a bottom layer and a surface layer, the bottom layer is formed by bonding waste rubber particles, and the surface layer is made of Ethylene Propylene Diene Monomer (EPDM) foaming material; the ethylene propylene diene monomer rubber foaming material is composed of ethylene propylene diene monomer rubber, calcium carbonate powder, white carbon black, a nitrogen-phosphorus compound flame retardant, nano montmorillonite powder, zinc oxide, reinforcing fibers, an organic foaming agent, an inorganic foaming agent, an antioxidant, an ultraviolet absorbent, a mildew-proof antibacterial agent, an accelerator, rubber oil and toner. The preparation process comprises the following steps: 1) manufacturing a bottom layer; 2) manufacturing a surface layer; 3) and (5) jointing the surface layer and the bottom layer. The rubber floor mat disclosed by the invention is large in elasticity, good in damping effect, good in wear resistance, flame-retardant and antibacterial, not easy to decolor and deform and warp, simple in preparation process, low in production cost and convenient to popularize and apply on a large scale.
