Abstract

The invention provides a creep type viscoelastic rubber waterproof coating and a production method thereof, belonging to the technical field of waterproof materials. It is made by mixing the following raw materials by weight percentage: 90# asphalt 30-40%, thermoplastic styrene-butadiene rubber 15-20%, butyl rubber 10-16%, active tackifying resin 8-12%, softening oil 7 -12%, coupling agent 3-5%, filler 8-10%; wherein said active tackifying resin is tackifying resin JT-260, alkylphenol acetylene tackifying resin, C5 petroleum resin is 1 according to mass ratio: 2:3~5 mixed composition. The waterproof material has excellent bonding performance, is sticky when touched, and is difficult to peel off. It can be bonded to wet substrates, and can also be bonded to wood, metal and other substrates. The membrane needs no maintenance, no overlapping, and high efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of waterproof products, in particular to a creep type viscoelastic rubber waterproof coating and a production method thereof. 【Background technique】 [0002] Creep type viscoelastic rubber waterproof coating is non-curable rubber modified asphalt waterproof coating (Non-curable rubber modified asphalt coating for waterproofing). Hot-melt waterproof coating. This product maintains the creep properties of viscous colloidal state, has the advantages of strong tensile ability, anti-repeated fatigue, and can be compounded with many coils. It is a multi-functional waterproof coating. This kind of waterproof coating maintains a viscous paste within the service life. It has self-healing, anti-seepage, anti-water channeling, anti-fatigue, anti-aging and other application advantages. It can seal the cracks and capillary pores of the base layer and adapt to complex construction. Working surface: It will not solidif...
