Process for preparation of water-proof sheets |
摘要 |
Disclosed is a process for preparing a water-proof sheet by forming a polymer coating on both the surfaces of a fibrous substrate fabric. At first, the fibrous substrate fabric is treated with a water repellant, and both the surfaces are subjected to the low temperature plasma treatment or corona discharge treatment. Then, a polymer coating is formed on both the surfaces. According to this process, the peel strength of the polymer coating is improved and the water absorbing property is reduced substantially to zero. If an inorganic fiber substrate fabric is treated according to this process, the bending resistance is highly improved in the resulting water-proof sheet.
