Abstract

The present invention provides a composite durable antistatic non-asphalt-based self-adhesive gas insulation board and its preparation method, which solves the problem that the gas insulation board in the prior art is a hard plastic board due to long-term high and low temperature changes in the use environment. It has the phenomenon of dimensional change, which leads to the technical problem of gas leakage. It includes a polymer waterproof board layer, a self-adhesive material layer and a polyurethane coating layer; the polymer waterproof board layer is the bottom layer, the self-adhesive material layer is covered on the polymer waterproof board layer, and the polyurethane The paint layer is the surface layer. The invention forms a composite weather-resistant and antistatic non-asphalt-based self-adhesive gas isolation board for gas tunnels through the compounding of polymer waterproof board layer, self-adhesive rubber material layer and polyurethane coating layer, thereby effectively preparing an excellent Mechanical properties, good flexibility, weather resistance, excellent gas insulation performance, excellent flame retardancy and antistatic properties, and easy construction and transportation of gas insulation panels.

Description

technical field [0001] The invention relates to a gas isolation board, in particular to a composite durable antistatic non-asphalt-based self-adhesive gas isolation board and a preparation method thereof. Background technique [0002] The anti-gas and waterproof isolation projects of tunnels in my country mainly need to meet gas barrier properties, flame retardancy, antistatic properties and excellent mechanical properties. Most of the gas barrier panels currently in use have poor gas barrier properties, are not antistatic, and are hard Due to the long-term high and low temperature changes in the use environment, there are dimensional changes in the plastic sheet, which leads to gas insulation performance defects; because of the long-term harsh use environment, the material has performance attenuation, and due to the lack of flexibility of the material, It is not easy to fold, which also causes some troubles for road transportation, and has the disadvantage of poor constructio...
