In a preferred embodiment of the present invention, be grouped into by the one-tenth of following masses number: polyether glycol 85 parts, vulcabond 48 parts, catalyzer 0.8 part, linking agent 4.5 parts, fire retardant 12.5 parts, 5.0 parts, softening agent and mill base 10.0 parts.

In a preferred embodiment of the present invention, be grouped into by the one-tenth of following masses number: polyether glycol 95 parts, vulcabond 55 parts, catalyzer 1.2 parts, linking agent 5.5 parts, fire retardant 15 parts, 6.5 parts, softening agent and mill base 10.0 parts.

The technical problem that the present invention also will solve is to provide the preparation method of above-mentioned this plastic floor mat, comprises the steps:

1) drying aids, puts into loft drier respectively by catalyzer, linking agent, fire retardant and softening agent, dry 2h under the condition of 80 ~ 90 DEG C;

2) pre-mixing, puts into reactor by polyether glycol, open stir, add vulcabond and linking agent gradually under stirring, after be warming up to 120 DEG C, insulation 2h, formed premix;

3) mix, open and stir, in premix, add catalyzer, fire retardant and softening agent, stirring velocity is controlled at 500 ~ 800r/min, add mill base after stirring 30min, then stir 30min, form work in-process plastic cement;

4) filter, extruding, work in-process plastic cement step 3) made filters, and obtains liquid plastic cement, then again on base material, coated technique, then through rolling, extruding, extrude or mould shape explained hereafter becomes the plastic floor mat of finished product.

The invention has the beneficial effects as follows: a kind of plastic floor mat of the present invention and preparation method thereof, technical process is simple, easy to operate, process controllability is good, be prepared into quality to stablize, the plastic floor mat that mentioned component and preparation technology prepare and obtain, has good mechanical property, has again good flame retardant properties and wear resistance simultaneously.
