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...

Examples

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...
