Abstract

The invention discloses a wear-resistant, flame-retardant and antistatic rubber floor mat and a production method thereof. The rubber floor mat is formed by laminating a bottom layer and a surface layer, and at least one layer of fiber gridding cloth is embedded in the surface layer; the bottom layer is formed by bonding waste rubber particles; the surface layer is formed by bonding ethylene-propylene-diene monomer particles; and the ethylene-propylene-diene monomer particles comprise ethylene-propylene-diene monomer, calcium carbonate, white carbon black, zinc oxide, a nitrogen-phosphorus compounded flame retardant, an antioxidant, an antistatic agent, an ultraviolet absorber, an anti-mold and antibacterial agent, an accelerator, rubber oil and a toner. The production method comprises thefollowing steps: 1) production of the bottom layer; 2) production of surface layer particles; 3) production of the surface layer; and 4) lamination of the surface layer and the bottom layer. The rubber floor mat has the advantages of good wear resistance, excellent flame retardant performance, excellent antistatic performance, large elasticity, and no discoloration, particle falling or deformation warping, and the production method ahs the advantages of simplicity, low production cost, and convenience in large-scale promotion and application.

Description

technical field [0001] The invention relates to a wear-resistant, flame-retardant and antistatic rubber floor mat and a preparation method thereof, belonging to the technical field of the rubber industry. Background technique [0002] Rubber floor mats refer to floor mats made of natural rubber, synthetic rubber and other polymer materials. They are generally installed in bathrooms, kitchens, gyms, kindergartens, sports fields, parks, playgrounds, etc., with the ability to keep the ground clean, Anti-slip, shock absorption and other functions. However, the rubber floor mats currently on the market generally have defects such as poor shock absorption effect, easy to breed bacteria and mildew, poor fire resistance, easy to wear and other defects, and the production cost is relatively high, requiring a large amount of rubber resources to be consumed, which limits its use. large-scale application. [0003] According to incomplete statistics, at least 50,000 automobile tires ar...
