Effect of blending with additives on mechanical properties of PVC architectural membrane material
Polyvinyl chloride (PVC) architectural membrane material is a species of composite textile material. In comparison with other architectural membrane materials such as PTFE or ETFE, PVC membrane material is much cheaper, softer and easier construction feasibility. In this paper, γ-methacryloxypropyl trimethoxy silane (KH-570), chlorinated polyethylene (CPE) and pellet binder (PB) were added into PVC paste, respectively. The mechanical properties (tensile strength, peel strength and tearing strength) of the coated fabric were investigated. It was found that the mechanical characteristics of PVC coated fabric were evidently affected by the addition of KH-570 in the coating paste. Both tensile strength and peel strength of PVC coated fabric were improved by the addition of KH-570. The addition of CPE into the coating paste had little effect on the mechanical properties of the coated fabric. The mechanical properties of the coated fabric were greatly improved by blending with PB, the peel strength enhanced 157％ and the tensile strength increased 150N/50mm, but the tearing strength was largely reduced.
