Abstract

The invention discloses a high-polymer waterproof coiled material hot-melt pressure-sensitive adhesive and a preparation method thereof. The hot-melt pressure-sensitive adhesive comprises the following components in parts by mass: 30-200 parts of elastomer composition, 40-100 parts of tackifying resin, 20-70 parts of plasticizer, 0.3-5 parts of stabilizer and 0.1-3 parts of additive. The elastomer composition is selected from SIS (styrene-isoprene-styrene) / SEPS (styrene-ethylene / propylene-styrene), SIS / SBS (styrene-butadiene-styrene), and / or SBS / SEBS (styrene-ethylene-butadiene-styrene). The mass ratio of the two components in the elastic composition is 1-20; the styrene in the SIS in the elastic composition accounts for 15-30 wt%, the styrene in the SEPS accounts for 10-30 wt%, the styrene in the SBS accounts for 20-50 wt%, and the styrene in the SEBS accounts for 10-40 wt%. The hot-melt pressure-sensitive adhesive has the characteristics of excellent ultraviolet aging resistance, favorable thermal aging resistance, high peel strength, simple technique and low cost.

Description

technical field [0001] The invention relates to the technical field of hot-melt pressure-sensitive adhesives, in particular to a polymer waterproof membrane hot-melt pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] In 1992, Grace Company invented the pre-laid waterproof membrane system and construction technology. For the first time, the polymer self-adhesive film waterproof membrane was used to realize the full adhesion between the bottom plate and the side wall of the construction space and the structural concrete, providing the best waterproof Effect. In 2009, Grace developed a pre-paved waterproof membrane suitable for China and put it on the Chinese market. In November 2008 and March 2009, the state issued relevant standards to vigorously promote the application of pre-paved construction technology and self-adhesive waterproof membrane materials. Since the polymer waterproof membrane is mainly HDPE, which is a non-polar mater...
