Soft felt and viscose are a new type of waterproof material researched and promoted in recent years. It is based on polyvinyl chloride, plasticizers, stabilizers and other base materials. The finished product is black, each roll is 10m long, with a width of 1m, a thickness of 1mm, and a soft texture. Technical performance parameters are as follows: soft felt: low temperature flexibility: -30 °C fold without cracks; tensile strength: more than 0.8MPa; tensile elongation at break: more than 120%; heat resistance: 80 °C without foaming, no stickiness; Water permeability: more than 0.2M Pa; Shore hardness: 50; water absorption: less than 0.5%; bulk density: 1600kg/m~3; heat aging retention rate: tensile strength of not less than 80%, elongation at break is not low At 70%. Viscose: hot work, drying time: surface drying 5 to 20 minutes; actual drying 2 to 10 hours. Bonding strength: 0.1 to 0.4 MPa, bulk density: 13 60 to 1380 kg/m~3. Cold work, consistency; 8 ~ 10cm; drying time: surface drying is less than 4 hours,
