Non-asphalt self-adhesion type EVA composite waterproof plate and processing technology thereof

The invention discloses a non-asphalt self-adhesion type EVA composite waterproof plate in the technical field of waterproof coiled materials. The non-asphalt self-adhesion type EVA composite waterproof plate is composed of an EVA waterproof base material, non-woven geotechnical cloth, a macromolecular hot melt adhesive and an isolating membrane, wherein the non-woven geotechnical cloth and the macromolecular hot melt adhesive are arranged on two sides of the EVA waterproof base material respectively; and the upper part of the macromolecular hot melt adhesive is covered with the isolating membrane. According to the technical scheme, through the improvement for the procedures, the non-woven geotechnical cloth (composite layer) and the macromolecular hot melt adhesive (self-adhesion layer) are arranged on two sides of the EVA waterproof base material respectively, and therefore, the non-asphalt self-adhesion type EVA composite waterproof plate for a tunnel, which is better in waterproofeffect, more convenient t
