The invention provides a composite durable antistatic non-asphalt-based self-adhesive gas separator and a preparation method thereof, which solve the technical problem that gas leaks due to the fact that the gas separator in the prior art is a hard plastic plate and has a size change phenomenon due to long-time high and low temperature change in a use environment. The waterproof coating comprises a high-molecular waterproof plate layer, a self-adhesive layer and a polyurethane coating layer; the polymer waterproof board layer is a bottom layer, the self-adhesive layer covers the polymer waterproof board layer, and the polyurethane coating layer is a surface layer. According to the invention, through the compounding of the high-molecular waterproof board layer, the self-adhesive glue layer and the polyurethane coating layer, the composite weather-proof antistatic non-asphalt-based self-adhesive gas isolation board for the gas tunnel is formed, so that the gas isolation board which has excellent mechanical property, flexibility, weather resistance and gas isolation performance, excellent flame retardance and antistatic property and is convenient to construct and transport is effectively prepared. |
