7. a kind of method for preparing any one of claim 1~6 rubber floor covering, it is characterised in that comprise the following steps：
（1）Weigh butadiene-styrene rubber by above-mentioned formula, it is ethylene propylene diene rubber, junked tire, polyvinyl chloride resin, expanded vermiculite, filler, dilute
Soil, stearic acid, conductive fiber, flame-retardant mixture material, accelerator, age resistor, antimony oxide, nano inorganic antimicrobial agent, it is standby
With；
（2）Junked tire is first broken into particle diameter and is the particle of 10~20 mesh, then carries out first time magnetic separation, after magnetic separation is finished,
First time grinding is carried out under oxygen free condition, gained waste tyre particle crosses 50~70 mesh；
（3）By step（2）The waste tyre particle of gained carries out second of magnetic separation, and second of magnetic separation condition is：Temperature 90
~100 DEG C, 0.04~0.06MPa of vacuum, after magnetic separation is finished, carry out carrying out second of grinding in a nitrogen atmosphere, gained gives up
Old tire particle crosses 80~90 mesh；
（4）Butadiene-styrene rubber, ethylene propylene diene rubber, expanded vermiculite, filler, rare earth, stearic acid are pulverized last and step（3）
Obtained waste tyre particle is stirred well mixed at normal temperatures, then uses ultrasonic frequency anti-for 100~300Hz catalysis
Answer 15~25 minutes, obtain mixed material；
（5）By mixed material input banbury banburying 5~10 minutes, mixing temperature was 80~90 DEG C, then sequentially adds PVC trees
Fat, flame-retardant mixture material, accelerator, age resistor, antimony oxide, nano inorganic antimicrobial agent, banburying 8~12 minutes, banburying
Temperature is 90~115 DEG C, and obtained banburying sizing material is transferred in mill glue and smashes glue, smashes the uniform rear bottom sheet of glue, and cooling stands 10
~12 hours；
（6）By step（5）Obtained film is placed in banbury, adds conductive fiber, carries out secondary banburying, secondary mixing time
For 3~5 minutes, secondary mixing temperature was 85~95 DEG C, the sizing material after secondary banburying is gone to glue is smash in mill, smash glue uniform
Bottom sheet, cooling, stand 10~12 hours afterwards；
（7）By step（6）Obtained film is first put into Rubber Extruder, extrusion sheet, then carries out sulfidization molding, remembers the rubber
Adhesive floor.
8. preparation method according to claim 7, it is characterised in that the step（7）Middle conditions of vulcanization is：Curing temperature
155~165 DEG C, 18~22MPa of sulfide stress, cure time is 15~22 minutes.
