Problems solved by technology

Today’s waterproof membranes are tailor-made according to the shape of the waterproof base layer in waterproof construction. For the base layer with complex shapes, multiple splicing is required. The waterproof membrane is difficult to bond, and the hidden danger of water leakage is large. At the same time, when the coil is in use, because it is in a curled and tight state for a long time, it is extremely easy to deform when it is used. For example, after a certain part is damaged, the local material will shrink, resulting in water leakage. The position of the point is shifted, which has great interference to the later maintenance and repair

Embodiment

[0017] Example: see figure 1 , the present invention provides a technical solution: a strong cross-membrane self-adhesive waterproofing membrane, comprising a base layer, an asphalt layer 4, and a self-adhesive layer 5, the asphalt layer 4 is arranged on the top of the foundation layer, and the self-adhesive layer 5 is arranged On top of asphalt layer 4.

[0018] Among them, the base layer includes a first film layer 1, a second film layer 2 and a glue layer 3, the first film layer 1 and the second film layer 2 are designed to be crossed, and the glue layer 3 is filled in the first film layer 1 and the second film layer. The cross gap of layer 2 and the outer surface, the first film layer 1 and the second film layer 2 have the same longitudinal and transverse elongation rates, the first film layer 1 and the second film layer 2 are both high-strength HDPE films, and the first film layer 1 and the second membrane layer 2 are made by the cross-lamination process. The self-adhesi...

Abstract

The invention discloses a strong cross film self-adhesive waterproof coiled material which comprises a base layer, an asphalt layer and a self-adhesive layer, the asphalt layer is arranged on the top of the base layer, and the self-adhesive layer is arranged on the top of the asphalt layer. The base layer comprises a first film layer, a second film layer and a glue layer, the first film layer and the second film layer are designed in a crossed mode, the glue layer is filled in the crossed gap and the outer surface of the first film layer and the second film layer, and the powerful crossed film is a high-strength HDPE film formed by adopting a crossed laminating and overlapping technology. The longitudinal and transverse elongation rates of the film manufactured by the process are the same, the coiled material does not deform, and the film is more attractive and more reliable in waterproof effect.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a strong cross-membrane self-adhesive waterproof roll material. Background technique [0002] Waterproofing membrane is a kind of waterproofing material, which can be divided into bitumen waterproofing membrane, polymer modified waterproofing membrane and synthetic polymer waterproofing membrane according to the main waterproofing components. When the current waterproof membrane is tailored according to the shape of the waterproof base layer and the gold one in the waterproof construction, multiple pieces of the base layer with complex shapes are required to be spliced ​​together. At the same time, when the coil is in use, because it is in a curled and taut state for a long time, it is extremely easy to deform during use. For example, after a certain place is damaged, the local material will shrink, resulting in water leakage. The position of the point is offset, wh...
