Problems solved by technology

In order to overlap the upper and lower side films of adjacent coils during construction, the upper cover layer includes mutually independent anti-adhesive layers 1-3 and PET film overlapping side layers 1-4, which need to be divided into two parts at different positions during manufacture. The film, especially the anti-adhesive layer 1-3 needs to be covered in the middle, leaving a section on both sides and then covering the PET film to overlap the side layer 1-4. The manufacturing process is complicated and there are many types of materials
In mass automated production, the existing product structure increases the complexity of the system and the difficulty of management, resulting in higher manufacturing costs

Embodiment

[0029] Embodiment: the easy tear edge film that is used for self-adhesive waterproof coiled material of the present embodiment is as figure 2 and image 3 As shown, it is an integrated surface covering film 2, which can be selected from existing polyethylene film or polyester film. An indentation line 2-2 is formed on the edge of the surface coating 2, and the indentation line 2-2 adopts an existing easy-to-tear structure, such as an easy-to-tear line formed by a row of longitudinal long holes, and the easy-to-tear line runs through the entire The distance between the two ends of the surface coating 2 and the outer edge is 10-15 cm. The surface film 2 outside the creasing line 2-2 forms the edge film 2-1, and the extending direction of the creasing line 2-2 is the same as the pulling direction of the edge film 2-1.

[0030] Its usage status is as Figure 4 As shown, the edge film 2-1, the creasing line 2-2 and the surface film 2 are integrally compounded on the upper surfa...

Abstract

The invention discloses an easily torn edge film for a self-adhesive waterproof roll. The easily torn edge film and a surface film of the self-adhesive waterproof roll to form a one body, the edge portion of the surface film is provided with an impression line, the edge film is formed on the surface film at the outer side of the impression line, and the extension direction of the impression line is same to the tearing direction of the edge film. The easily torn edge film can simplify the film laminating technology of the self-adhesive waterproof roll and reduce the manufacturing and construction cost.

Description

technical field [0001] The invention relates to an auxiliary material for a waterproof coiled material, in particular to an easy-tearable edge film for a self-adhesive waterproof coiled material, and belongs to the technical field of layered products. Background technique [0002] The self-adhesive waterproof membrane is a self-adhesive waterproof membrane with resin and asphalt as the base material, the upper surface is covered with polyethylene film and aluminum foil, and the lower surface is covered with a release layer. The release layer is usually made of silicone oil that can be peeled off. membrane. Due to its strong self-adhesive and self-healing properties, it is very suitable for high and low temperature environments and on-site construction that cannot be fired, and is also suitable for waterproof and anti-corrosion projects for pipelines. Has the following advantages: [0003] 1. There is no need for adhesives and hot baking during construction, and it can be f...
