Punching polyethylene self-adhered waterproof coiled material as well as preparation method and using method thereof

Abstract

The invention discloses a punching polyethylene self-adhered waterproof coiled material as well as a preparation method and a using method thereof. A punching area and a self-adhering area are arranged on two sides of the coiled material in the length direction of the coiled material respectively; adhering holes are formed in the punching area at intervals, and the adhering holes are through holes; the self-adhering area is coated with a self-adhering adhesive. The preparation method comprises the following steps: in the production processing process, processing the coiled material on an assembly line in the punching area and the self-adhering area, forming the adhering holes in one side of the coiled material, and performing blade coating on the self-adhering adhesive on the other side ofthe coiled material. The using method comprises the following steps: (1) clearing a base layer; (2) paving cement gel, and adhering the punching area; (3) leveling the adhered punching area, so thatthe adhering holes can be filled with the cement gel; (4) paving and pasting the self-adhering area onto the punching area in a lapping manner, so that two punching polyethylene self-adhering waterproof coiled materials are tightly and smoothly connected. Through the technical scheme, false adhesion can be avoided to cause cracking, layering and falling of a waterproof layer.

Description

technical field [0001] The invention relates to a waterproof coiled material and a preparation method thereof, in particular to a perforated polyethylene self-adhesive waterproof coiled material and its preparation and use methods.
