Double-sided self-adhesive water-proof adhesive tape

Abstract

The invention discloses a double-sided self-adhesive water-proof adhesive tape, which contains butyl rubber. The water-proof adhesive tape comprises the following components in parts by weight: 30-70 parts of asphalt, 5-25 parts of oil, 2-20 parts of butyl rubber, 2-20 parts of a styrene-butadiene block copolymer, 2-20 parts of an SBRS (Styrene Butadiene Rubber Styrene) modifier, 2-20 parts of a tackifying resin, 2-20 parts of a PE (Poly Ethylene) modifier, 0-20 parts of rubber powder and 10-35 parts of stone dust. The butyl rubber is introduced as a bonding modifier, so that the bonding performance and storage stability of a material are improved greatly. The water-proof adhesive tape can be durably and tightly bonded with fundamental planes such as concrete, cement mortar, metals, plastic, glass, wood and the like, and has excellent physical property, superior high and low temperature resistance, high tensile strength, high adaptability to deformation and cracking of fundamental planes, high water tightness, high air tightness, high chemical performance, high corrosion resistance and high size stability.

Description

technical field [0001] The invention relates to a double-sided self-adhesive waterproof tape. Specifically, the invention designs an environment-friendly sealing adhesive material used for sealing and waterproofing treatment of window frames, door frames, pipe openings, and eaves. Background technique [0002] The external windows and door frames of buildings are the windows connecting the interior of the building with the outside world, but it is precisely because of the existence of these windows that the interior decoration is often moldy and black due to leakage, and the gaps between the pipe openings are greatly affected by water seepage and leakage. It affects the living environment and the service life of the building, and brings a lot of trouble and inconvenience to the user. At present, the waterproof treatment of doors and windows on the market is generally applied with waterproof mortar, and glass glue is used for sealing and caulking for waterproofing, and certai...

AI Technical Summary

Problems solved by technology

[0005] Waterproof mortar is used for smearing and sealing treatment, and glass glue is used for sealing. Because no high-elastic sealing material is used, the mortar layer on the edge of the window frame will crack and fall off, resulting in leakage. In addition, low-grade glass glue is used for caulking, glass glue Premature failure, rain seeps into the room from the outside of the window sill under the action of wind
