Layer is fixedly connected, and the anti-downside for piercing through layer is equipped with steel mesh layer, and downside and the burlap layer sewing of the steel mesh layer are integrated,
The downside of the burlap layer is equipped with degradation plastic basal layer, and the lower surface of the degradation plastic basal layer is equipped with anti-skidding convex
It rises.
Preferably, the anti-skid bulge includes adhered layer, and the downside of the adhered layer is equipped with non-slipping block, and the non-slipping block is
The lower surface of prismatic table shape structure, non-slipping block is fixedly installed several anti-slop serrations, and anti-slop serrations are pyramid-shaped structures.
Preferably, the junction of the steel mesh layer and burlap layer interspersed connection of antistatic copper wire, antistatic copper wire is in S
Shape.
Preferably, the anti-skid bulge is arranged in matrix form, and there are gaps for adjacent anti-skid bulge.
Preferably, the thickness of the glue adhesive layer is 0.2-0.5 millimeters.
Compared with prior art, the beneficial effects of the invention are as follows:Structure of the invention is reasonable, can by the way that steel mesh layer is added
Electrostatic effective to increase the intensity of carpet, and that carpet can be guided to generate avoids the safety for influencing vehicle, anti-by being added
Layer is pierced through, steel mesh and antistatic copper wire can be prevented to be broken and pierce through carpet, protect the personal safety of user, it is degradable by being added
Plastic substrate, after car carpeting damages can natural degradation, it is environmentally friendly, it is pollution-free, be suitble to promote the use of.
Description of the drawings
