Base material of self-adhesive water-proof coiled material and self-adhesive water-proof coiled material manufactured by the same

Abstract

The invention discloses the base material and self-adhering water-proofing coiled material made with the base material. The base material is made by the modified PVC material, comprising PVC, polyester plasticity agent, modifier, filling agent, stabilizer, lubricating agent and antiaging agent. On the surface of base material add creep rubber bitumen self-adhering layer and non-stick coating to get self-adhering water-proofing coiled material. The self-adhering water-proofing coiled material has good physical-mechanical properties, thermal distortion property, elasticity, cold-resistant, flame-proof, abrasion-proof and resistance to chemical attack; it also has low volatility and long life.

Description

technical field

[0001] The invention relates to the field of building waterproof materials, in particular to a self-adhesive waterproof roll material made from the base material of the waterproof roll material with single-sided or double-side self-adhesive adhesive. Background technique

[0002] At present, the existing waterproof rolls with single-sided or double-sided self-adhesive (and isolation layer), the base material (or tire material, which is a sheet) generally uses polyester felt or PE film material, not PVC. PVC has many advantages such as good mechanical and physical properties, good thermal deformation performance, good bonding force with self-adhesive adhesive, good elasticity, cold resistance, flame retardancy, wear resistance, chemical corrosion resistance and low leakage of gas and water vapor. Why is PVC not popular? What about using as a base material? This is because when PVC material is used as the base material, due to the migration of the plasticizer...
