(3) Upper tyre
A. Preparing a filament II type polyester base;
B. lifting the tire base to a tire base unfolding device, introducing the tire base onto a tire base lapping machine, a tire base stopping machine, a tire base drying machine and a deviation adjusting device, and entering an oil immersion tank;
(4) Film coating
A. Checking whether the surface of the laminating roller is clean;
B. cooling water is injected into the water tank to reach the position of an overflow surface, so that the normal circulation of the cooling water is ensured;
C. placing the PE film on a film covering device, and fastening bolts at two ends to fix the PE film at the middle position of the film covering device;
D. introducing one end of the PE film onto a laminating roller, and flattening the film surface;
(5) Cooling down

Furthermore, the type of the asphalt is AH-70 or AH-90, and the specific indexes are as follows,
further, the softening oil is base lubricating oil or naphthenic oil with pour point less than-30 ℃ and flash point more than 230 ℃.
Further, the SBS is a styrene-based thermoplastic elastomer, i.e., a styrene-butadiene-styrene block copolymer.
Further, the metallocene polyolefin is a special semi-crystal formed by copolymerizing ethylene and propylene, the melt flow rate is 3-8g/10min, and the density is 0.86-0.9g/cm 3 The Vicat softening point is 50-70 ℃, and the breaking elongation is more than 800%.

Furthermore, the talcum powder is white or white-like, fine and non-gritty powder, and the main component of the talcum powder is talcum powder with the fineness of 180-200 meshes.
The novel metallocene polyolefin composite modified asphalt waterproof coiled material and the preparation method thereof have the advantages of strong bonding force, aging resistance and environmental protection. The physical and mechanical property indexes of the obtained novel metallocene polyolefin composite modified asphalt waterproof coiled material are shown in the following table (taking type II as an example):
compared with the prior art, the novel metallocene polyolefin composite modified asphalt waterproof coiled material and the preparation method thereof have the following advantages:
(1) Has more excellent high and low temperature performance. After the SBS modified asphalt is secondarily modified by the semi-crystalline metallocene polyolefin, a metallocene polyolefin-SBS joint body is formed inside the asphalt colloid system, so that a space network structure in the asphalt system is more complete and firm, and the high-temperature sensitivity is reduced. Meanwhile, the metallocene polyolefin participating in modification is a special semi-crystal of ethylene-propylene copolymerization, a molecular chain contains a soft propylene side chain, the flexible component of asphalt is increased, and the deformability is enhanced, so that the metallocene polyolefin has more excellent low-temperature anti-cracking performance;
(2) Has more excellent weather resistance and stability. The metallocene polyolefin-SBS joint formed in the asphalt can absorb and fix more asphalt light components, and the swelling is more sufficient, so that the conversion of the light components such as saturated components and aromatic components in the asphalt to the heavy components such as colloid and asphaltene is effectively prevented, and the aging is delayed. The polyolefin molecular chain has no unsaturated bond, has stable chemical property and is not easy to crack, and the two modifiers form a compatible system in the molten asphalt due to winding of the polyolefin molecular chain and the SBS molecular chain under the high-speed shearing condition in the process of producing the asphalt coating material, so that the fracture rate of the butadiene chain segment C = C in the SBS molecular chain is further slowed down, and the material has extremely obvious stability and weather resistance;
(3) Has higher seam peel strength. The joint peeling strength of the hot-melt SBS modified asphalt waterproof coiled material mainly depends on the cohesion of the waterproof material asphalt coating material per se to a certain extent, SBS can enhance the cohesion of the material, but the modification mechanism of SBS on the asphalt determines that an SBS-asphalt blending system has instability, and the metallocene polyolefin-SBS coupling body subjected to secondary modification is distributed in the asphalt more uniformly to serve as a firmer asphalt framework, so that the cohesion of the material per se is improved, and the polyolefin is a thermoplastic material and has hot welding property, so that the material has higher joint peeling strength;
therefore, compared with the comprehensive performance of similar products, the novel metallocene polyolefin composite modified asphalt waterproof coiled material disclosed by the invention has excellent innovation in the aspects of physical indexes such as high temperature, low temperature, weather resistance, joint peeling strength, storage stability and the like.
Has great advantages in production cost and construction mode, and has certain economic benefit and social benefit.
