Problems solved by technology

However, due to the influence of the environment during the use of PVC waterproof membranes, small molecules such as plasticizers often migrate and precipitate. After losing the plasticizers, the PVC waterproof membranes will shrink, crack, and harden. It may lead to the failure of the waterproof function of the PVC coil; at the same time, when using adhesives for construction, as time goes by, the plasticizer inside the PVC coil tends to migrate to the adhesive layer, between the adhesive and the PVC coil. Form an isolation layer, which causes a sharp drop in bond strength, resulting in weak bonding or degumming
[0004] The prior art has the following defects: (1) The mechanical properties of the PVC waterproof membrane are not high; (2) The low temperature flexibility is poor; (3) The service life is short

Description

technical field [0001] The invention relates to an elastomer modified PVC waterproof membrane and its production process, specifically the mechanical properties and usability of PVC waterproof membrane modified by elastomer chlorinated polyethylene (CPE) and its production process, belonging to field of waterproof materials. Background technique [0002] The polyester fiber internally reinforced polyvinyl chloride (PVC) waterproof membrane is a thermoplastic PVC membrane. The membrane uses polyester fabric as a reinforcing rib. Through a special extrusion coating process, the double-sided Polyvinyl chloride plastic layer and polyester reinforcing rib in the middle are combined to form a polymer membrane. The combination of advanced polyvinyl chloride plastic layer and mesh structure polyester fabric makes the membrane have excellent dimensional stability and low thermal expansion coefficient. [0003] In accordance with the requirements of the national development plan, ne...
