2. A process of compounding a transparent non-slip carpet as claimed in claim 1, wherein: the TPE material of the transparent particles is preheated to 65 ℃ to remove moisture on the surface.
3. A process of compounding a transparent non-slip carpet as claimed in claim 1, wherein: the pressure between the rubber rod (5) and the embossing rod (6) is 45-55 kg during compounding.
4. A process of compounding a transparent non-slip carpet as claimed in claim 1, wherein: the extrusion amount of the paste TPE is 1.1-1.8 Kg per square meter.
5. A process of compounding a transparent non-slip carpet as claimed in claim 1, wherein: the compounding speed of the fabric layer and the TPE layer is 0.6-1.3 m/min.
6. A process of compounding a transparent non-slip carpet as claimed in claim 1, wherein: TPE layer bottom surface is suppressed out the skid resistant course through knurling rod (6), the skid resistant course is formed by a plurality of polygon combinations that are equipped with the three-dimensional anti-skidding line of elasticity, and two adjacent polygonal a plurality of three-dimensional anti-skidding lines of elasticity are towards different directions.
7. A process of compounding a transparent non-slip carpet as claimed in claim 1, wherein: the temperature of 15 heating areas of the die (3) is kept between 190 and 200 ℃ in the 1 st to 5 th heating areas and the 11 th to 15 th heating areas, and is kept between 180 and 190 ℃ in the 6 th to 10 th heating areas.
8. A process for compounding a transparent non-slip carpet as claimed in any one of claims 1 to 7, wherein: when the host is preheated, the temperature is reduced by 5 ℃ in summer and increased by 15 ℃ in winter.
9. A process for compounding a transparent non-slip carpet as claimed in any one of claims 1 to 7, wherein: the fabric layer is a polyester material layer, a wool material layer, a nylon material layer, a polypropylene material layer or a leather layer.
