Composite pre-laid waterproof coiled material

Abstract

The invention discloses a composite pre-laid waterproof coiled material which comprises a modified asphalt polyester tire coiled material base body and an adhesive layer and a protection layer which are arranged on the modified asphalt polyester tire coiled material base body, wherein the adhesive layer is used for adhering the protection layer onto the modified asphalt polyester tire coiled material base body; the protection layer comprises granular sand or colloidal particles; the adhesive layer is a hot-melt pressure-sensitive adhesive and is used for adhering the protection layer with the modified asphalt polyester tire coiled material base body into a whole. Due to the mode, the composite pre-laid waterproof coiled material can be firmly adhered into concrete to form a skin type waterproof layer together with a concrete structure; long-time waterproofing can be realized, and water breakthrough is avoided; furthermore, the adhesive layer in the waterproof coiled material cannot be irradiated by ultraviolet, so that the adhesive strength is high, and the construction performance is high.

Description

technical field [0001] The invention relates to building waterproof materials, in particular to a composite pre-paved waterproof coiled material. Background technique [0002] Waterproof membrane 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 basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. Waterproof membrane products mainly include bitumen waterproof membrane and polymer waterproof membrane. Asphalt waterproofing membrane is popular in construction and design departments because of its low price and convenient use. It is used in large quantities and is mainly used for foundation waterproofing at the bottom of buildings, and also for waterproofing exposed parts such as roofs. The raw materials of bi...

Problems solved by technology

However, most of the above-mentioned improved technical solutions are improved designs aimed at the service life of the waterproofing membrane, reducing the cost and improving the high and low temperature creep of the membrane. The durability of the junction is rarely concerned, and the waterproof membrane is easily exposed to the outdoors during the construction process, and it is exposed to ultraviolet radiation, which will cause the aging of the adhesive layer and affect the adhesion of the waterproof membrane when it is used.

In order to avoid the influence of ultraviolet rays on the waterproof membrane, construction workers often do not tear off the isolation protective film outside the waterproof membrane, but wait until the waterproof membrane is used before tearing it off, but because the isolation protective film is not removed for a long time, it will As a result, the isolation protective film is closely bonded to the waterproof membrane, which is difficult or even impossible to tear off, thus affecting the use effect of the waterproof membrane in the later stage

And the long-term experience of the engineering personnel at the construction site has found that when the waterproof membrane is used in the construction process, the bonding performance of the waterproof membrane and the concrete and other building materials used in the construction, and the structural performance of the concrete mixed with the poured concrete will be directly affected. It affects the waterproof performance of waterproof membranes to buildings, and there are few improvements or innovative designs for waterproof membranes from this point of view in the prior art, and there are almost no reports
