(3) heat refining: 50～55 ℃ of roller temperature, three triangle bags of three thin-passes, two sections heat refining slices of roll spacing are adjusted in the back;

(4) rolling out film: roll spacing is decided 45～55 ℃ of temperature by product specification;

(5) one section die mould sulfuration of drum-type: the pressure 0.8～1.2Mpa of drum vulcanizer, linear velocity 2～3m/min, 150～180 ℃ of temperature;

(6) tank type vulcanizing: the vulcanizing boiler that post vulcanization adopts thermal oil to heat up, cure conditions is air pressure 0.3～0.4Mpa, and temperature is 150～180 ℃, and the time is 1～3h;

(7) test package warehouse-in.

By top narration as can be seen, the present invention has the following advantages: the tensile strength height, and elongation is big, and aging resistance height, long service life have performances such as good puncture resistance, erosion resistance and anti-bacterium.Production method of the present invention organically combines former traditional rubber drum-type sulfuration and pressure-pot vulcanization process, the change one step cure is post vulcanization, and one step cure makes the product die mould, and the surface produces different required decorative patterns, to increase the specific surface area of adhesive face, increase the visual appearance of product simultaneously.The present invention has improved the performance of product, has improved productivity, has reduced production cost and equipment cost, simultaneously energy efficient.

Following table is the survey report that relevant authoritative inspection department is done leading indicator of the present invention:

Project	Index	Assay
			Fracture tensile strength Mpa 〉=	4.0	4.9
Tensile yield % 〉=	450	472
			Tear strength kN/m	18	20.1
