Abstract

The invention discloses an environmentally friendly high polymer self-adhesion waterproof rolled material. The environmentally friendly high polymer self-adhesion waterproof rolled material comprises a high polymer waterproof base layer, an upper enhanced layer, an upper self-adhesion layer, an upper isolating layer, a lower enhanced layer, a lower self-adhesion layer and a lower isolating layer, wherein the upper enhanced layer, the upper self-adhesion layer and the upper isolating layer are successively arranged on one side of the high polymer waterproof base layer; the lower enhanced layer, the lower self-adhesion layer and the lower isolating layer are successively arranged on the other side of the high polymer waterproof base layer; the high polymer waterproof base layer is a high-density polyethylene intersected layer pressed film; the high polymer waterproof base layer comprises an adhesion promoter; the thickness of the high polymer waterproof base layer is 0.1-0.2 m; the upper enhanced layer and the lower enhanced layer are polypropylene non-woven fabric enhanced layer; the upper self-adhesion layer and the lower self-adhesion layer are high polymer SIS hot melting pressure-sensitive adhesive layers; the upper isolating layer is a photocatalyst film isolating layer; the thickness of the upper isolating layer is 50-80 nm; and the lower isolating layer is silicon oil film isolating layer. The environmentally friendly high polymer self-adhesion waterproof rolled material has the beneficial effects that the waterproof rolled material is non-toxic and odorless, safe and environmentally friendly, high in tensile strength, good in tear resistance and convenient to construct.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to an environmentally friendly polymer self-adhesive waterproof coiled material which is non-toxic, tasteless, safe and environmentally friendly, has high tensile strength, good tear resistance and convenient construction. Background technique [0002] Waterproof roll material is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering foundation and building There is no leakage connection between objects, which is the first barrier for waterproofing of the whole project and plays a vital role in the whole project. [0003] With the rapid development of the economy, the environmental smog is becoming more and more serious, and environmental protection issues are getting more and more attention and attention from...

Problems solved by technology

Asphalt waterproofing membranes are low in cost, but low in tensile strength and elongation, poor in temperature stability, easy to flow at high temperatures, brittle at low temperatures, poor in aging resistance, and short in service life; and harmful gases are easily produced during the production process, causing environmental damage pollution

In addition, its production and use process is cumbersome, the process is complicated, and there is a high labor cost; in addition, in the prior art, the asphalt coil needs to be baked with an open flame to make it melt and bond with the foundation. During the baking process, the baking temperature and time need to be strictly controlled. If the baking is overdone, it will cause damage to the coil and carbonize the asphalt, resulting in aging and water leakage. If the baking temperature is not enough or the time is too short, the PE film on the surface will not melt. The bond is not firm and causes water leakage in the later stage

[0004] To sum up, the existing asphalt-containing waterproofing membranes require a lot of manpower and material resources, and the material performance is low, not environmentally friendly and energy-saving. Harmful gases are produced during construction, causing environmental pollution, and even prone to fire, causing harm to people and property. Therefore, at present, A new energy-saving and environment-friendly waterproof membrane is needed
