Abstract
Description
technical field
[0001] The invention relates to an adhesive tape for matching polymer pre-laid waterproof coiled material and its construction application. Background technique
[0002] The polymer pre-laid waterproof membrane is formed by coating the polymer self-adhesive on the surface of the polymer sheet main body (HDPE, TPO, etc.), and finally spreading the particle layer on the adhesive layer; It has good tensile strength and elongation at break, and excellent physical properties, so there is no need to construct a protective layer during construction, which greatly reduces the construction period and cost; and the coiled material layer can be fully adhered to the post-cast concrete floor without water leakage, which is the current The most economical and reliable solution for basement floor waterproofing.
[0003] However, through a large number of engineering examples, there are still the following problems in the on-site construction of polymer pre-laid waterproof ...
Examples
Embodiment Construction
[0037] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0038] The invention provides an adhesive tape for supporting polymer pre-laid waterproof coiled materials, which includes: PE release film, polymer self-adhesive adhesive film, and strong cross layer arranged sequentially from bottom to top. Pressed PE composite film, polymer self-adhesive film, special particle layer on the surface;
[0039] The polymer self-adhesive film is composed of the following components in parts by weight: 25-50 parts of styrene-isoprene-styrene block copolymer, 10-30 parts of plasticizer, 30-60 parts The first tackifying resin, 3 to 10 parts of nano fillers, 10 to 20 parts of the second tackifying resin, 0.02 to 0.05 parts of ultraviolet absorbers, ...
