preparation example Construction

[0017] A method for preparing a self-adhesive SBS modified bitumen waterproofing membrane, comprising the following steps:

[0018] 1) Add 1 / 2 halogenated butyl rubber, 1 / 3 filler, and 1 / 6 styrene-isoprene-styrene block copolymer to the multifunctional rheometer, set the chamber temperature to 60°C, and set the rotating speed to 60°C. 70r / min, add vulcanization aid and vulcanization accelerator after banburying for 2min, heat up to 180℃ for banburying for 10min, and then cool as material A for use;

[0019] 2) Add polyisobutylene and plasticizer to the reaction kettle, heat up to 180°C, rotate speed 20r / min, add material A and stir for 40min, then add ethylene-vinyl acetate copolymer and tackifying resin, stir for 1h, and finally cool down to 130°C Add anti-aging agent and deodorant, stir well and serve as ingredient B for use;

[0020] 3) Spray material B evenly on the surface of the SBS coil through the glue spraying equipment, and then cover it with a release film. The thi...

Abstract

The invention belongs to the technical field of waterproof coiled materials, and particularly relates to an SBS modified asphalt waterproof coiled material capable of achieving self-adhesion construction and a preparation method thereof.The SBS modified asphalt waterproof coiled material is prepared from 80-100 parts of ethylene-vinyl acetate copolymer, 20-30 parts of halogenated butyl rubber, 15-25 parts of tackifying resin, 3-5 parts of styrene-isoprene-styrene block copolymer and 50-100 parts of polyisobutene. According to the non-asphalt-based self-adhesive material disclosed by the invention, a non-asphalt-based rubber component and an SBS modified asphalt rubber component are embedded together through vulcanization, and the problem of poor compatibility of a non-asphalt-based self-adhesive material and an SBS coating material is mainly solved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and in particular relates to a self-adhesive constructionable SBS modified bitumen waterproofing coiled material and a preparation method thereof. Background technique [0002] The self-adhesive SBS modified bitumen waterproofing membrane is a new product on the market in recent years, which mainly solves the problems of poor heat resistance of the self-adhesive membrane and hot-melt construction of the SBS membrane. It is an asphalt-based self-adhesive material and a non-asphalt-based self-adhesive material, but the asphalt-based self-adhesive material has the problems of easy aging and poor bonding effect. Layered. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a self-adhesive SBS modified bitumen waterproofing membrane and a preparation method thereof. The problem of poor compatibility between asphalt-based self-adhesive and SBS coa...
